The TMNT Kraang Villian Detailing The Lurker, Multiverse, Reptilian Brotherhood, Irish, Artifacts, Bees, Robot Clones & More

TMNT: THE LURKER MULTIVERSE

Brotherhood, Reptilian, Bee, Irish & Robot Clone

This piece is really about the Lurker - the tentacled, other-dimensional entity this blog tracks through the Cobra/2012portal disclosure material, said to have fully emerged in 1996. Krang keeps surfacing as one of its clearest pop-culture stand-ins: an other-dimensional, tentacled brain-entity, and the recurring motifs around him line up with the same markers tracked elsewhere on this blog - the Irish thread running through the name O'Neil, the Bee/Wasp theme, the multiverse crossovers, the reptilian Krangazoids and Brotherhood, repeated Earth-invasion plots, the Cube/Transport Artifact, the 1996 timing behind "The Next Mutation," and the android/clone doubles built around O'Neil. This profile lays all of that out - pulled from two separate shows, the 1987 series and the 2012 series - merged into one continuous read organized by topic instead of by show. In 1987, Krang is a single exiled warlord. In 2012, the Kraang are an entire enslaved Hive Mind race. The two are directly linked - Krang and Kraang Sub-Prime are cousins - and that link gets its own section below. Where a detail is specific to one show, that's noted inline.

1. Origin & Identity +

Origin & Identity

Why It Matters

Both versions start from the same basic shape: an intelligence exiled from - or native to - another dimension, without a stable body of its own, reaching Earth through a Technodrome or portal network

That's the exact profile this blog tracks under the Lurker framework - a tentacled, other-dimensional entity without a body of its own, needing hosts and hardware to operate here. Everything else in this piece, the Shredder alliance, the technology, the clones, the multiverse crossovers, builds on this basic setup

Both trace back to the same lineage - the Utrom race - just diverging differently in each show's continuity

1987: Krang was originally a reptilian being with a full body (confirmed in "Invasion of the Krangazoids"); a dictator/warlord in Dimension X who commanded brutal campaigns using Rock Soldiers, with General Traag as his fanatically loyal subordinate

1987: built the Technodrome with help from Drakus, whom he then banished to Earth

1987: an unexplained incident stripped Krang of his reptilian body, reducing him to a brain-like form and exiling him from Dimension X to Earth - the Technodrome came with him

2012: the Kraang are a telepathically enslaved Hive Mind faction of Utroms, corrupted by and serving Kraang Prime; their goal is to conquer and mutate planets, Earth included, as staging grounds in their war with the Triceratons, with an ultimate ambition to conquer all of Dimension X and beyond

2012: since Kraang Prime's death, the Kraang reverted back into ordinary Utroms

2012 origin story ("The War for Dimension X"): the Utroms were originally a peaceful, knowledge-prizing race. A scientist named Kraang discovered a mutagenic substance from a local worm species, the Kraathatrogon, and it transformed him into a giant with immense psychic power

He then conquered and enslaved the Utrom race, turning them into psychic clones of himself and erasing their individual identities - renaming himself Kraang Prime and renaming the entire species after himself

Distinct from Bishop's Utroms - a tribe that defected from the Hive Mind centuries earlier and exist independently

Krang (1987) and Kraang Sub-Prime (2012) are cousins - full crossover story in Section 6

2. Dimension X +

Dimension X

Why It Matters

This is quite literally the entity's home - the place it operates from before crossing into ours, which is the core shape this blog tracks: something operating from outside our dimension that reaches through to influence and inhabit Earth

Both versions independently land on the same ambiguous "is it even a separate dimension, or just very far away" framing - a hedge worth noticing in its own right

Dimension or Galaxy?

1987The show never settles it - gives evidence for both readings. Interplanetary space is usually shown as orange or reddish; Shredder calls it "a far off galaxy"; Krang references an actual physical distance between Earth and Dimension X; Baxter Stockman travels there via spacecraft rather than a portal, leaning toward the galaxy reading

2012No such ambiguity here - it's explicitly a separate dimension with its own physical laws that don't match Earth's, reached through portals and Transport tech rather than travel through space

The Environment

1987Largely undescribed beyond the reddish/orange coloring of its space - the show is more interested in specific worlds within it (see locations below) than the dimension's general conditions

2012Actively hostile - a nitrogen-and-sulfur atmosphere, thick fog, and toxic air that only aliens and Kraang-made mutants (Leatherhead, Tiger Claw, Alopex) can breathe; its water carries a hydrocarbon that dissolves anything native to Earth's dimension, except April - later explained by her hybrid biology

Dimension X, 2012 series

2012 Episode History

"It Came From The Depths": Leatherhead's flashback reveals he was mutated and raised in a Kraang lab here

"TCRI": Donatello coins the name "Dimension X" for the Kraang's homeland

"Showdown, Parts 1-2": the Kraang are shown contacting Kraang Prime, who came to Earth from Dimension X specifically to terraform it for Kraang habitation

"The Manhattan Project": the Kraang import Kraathatrogons - the same worm species Kraang Prime's original mutagen came from - to Earth

"The Wrath of Tiger Claw": Tiger Claw's flashback shows him fighting his way through multiple dimensions

"Plan 10": Raphael gets a look at the Kraang's invasion plans

"Into Dimension X": time runs faster here than on Earth - Michelangelo is stranded for what feels like months, Leatherhead visibly ages after decades; also reveals where the Kraang Power Cell comes from, and that much of the environment reacts to sound

"Battle for New York, Part 1": April has recurring dreams of the mutated, enslaved humans the Kraang are forcing to work for them

"Battle for New York, Part 2": the Turtles and the Mutanimals fly in to rescue and de-mutate the captured humans; Kraang Sub-Prime secretly tails them; a Kraathatrogon downs their blimp; they steal a Kraang Stealth Ship, crash into a mutagen-powered Technodrome, convert its mutagen into Retro-Mutagen, and de-mutate the humans island by island while fighting off Sub-Prime and Kraang Prime; the Technodrome is destroyed crashing into an asteroid, and the surviving Kraang are teleported back to Dimension X

"Annihilation Earth!, Parts 1-2": Michelangelo offers the Triceratons Dimension X's location in exchange for sparing Earth; they refuse under Zanmoran's orders

"Tale of Tiger Claw": as children, Tiger Claw and Alopex wandered through an open door into Dimension X and were mutated there; when they returned home, years had passed for them while their own world had barely moved on

Trivia & Crossover Echo

1987The 1987 Shredder and Krang once accidentally opened a portal into the 2012 version of Dimension X; despite being outsiders, the Rock Soldiers there obeyed them anyway - a small echo of the crossover covered in Section 6

2012"TCRI" is the only episode where Dimension X's air appears green instead of its usual pink - that particular gas turns out to be poison gas from the research institute, not real Kraang atmosphere

Dimensional Limbo 1987 series

Dimensional limbo, the space between dimensions

A separate location from Dimension X itself - the space between dimensions, not a place in it

This is where Krang secretly banishes the Krangazoids instead of sending them home as promised (full story in Section 6)

Krang also banishes Baxter the Fly here at another point in the series

Recurs several times across the show's run as a go-to way to get rid of someone permanently

3. Relationship With Shredder +

Relationship With Shredder

Why It Matters

In both versions, Shredder is the earthly power that hosts and enables the other-dimensional entity - giving Krang a body, a base, and a foothold on Earth in exchange for his technology

That's the same shape this blog tracks elsewhere: an earthly network providing cover and cooperation for something operating from outside this dimension, with the human partner ultimately expendable once its usefulness runs out

The Alliance Itself

1987Technodrome and Krang end up in Oroku Saki's hands after the exile; the alliance is uneasy from the start, Krang's demands straining it constantly

2012Shredder never allies with the Kraang the way 1987's Shredder does with Krang - it's transactional, built on capture and interrogation rather than partnership

The Body / Technology Exchange

1987Krang wants a new body in exchange for tech and conquest help; Shredder resists (fears a rival) but gives in - the android body is built from Krang's own blueprints in "Shredder & Splintered." Once bodied, Krang reverts to megalomania, dreaming of an Earth-side Rock Soldier army, ruling with or without Shredder

2012Shredder captures a Kraang operative and takes an interest in weaponizing their technology after "The Alien Agenda"

Their View of the Turtles

1987Krang rarely fights directly, engaging mainly when the Technodrome is operational; he runs the actual scheming for 7 seasons and sees the Turtles as annoyances, not the personal enemies Shredder does

2012By "The Pulverizer Returns!" both sides admit they share a common enemy in the Turtles - full episode detail is in the Section 6 timeline

How It Plays Out

1987Shredder's honor-driven impulsiveness repeatedly wrecks Krang's calculated plans; the alt-timeline "Shredderville" shows Shredder abandoning Krang entirely once conquest is complete, leaving him bodyless with a wrecked Technodrome - the alliance is disposable from Shredder's end

2012No long-term partnership ever forms here - the relationship stays adversarial-with-overlap rather than building toward a betrayal

4. Personality +

Personality

Why It Matters

The Kraang's defining trait - a mass of identical drones that lost all individual identity and refer to themselves only as "Kraang" - lines up with how this blog's sources describe the Lurker itself: entities stripped of individuality that merged into one undifferentiated mass

Krang's psychological state swinging between submissive and megalomaniacal depending on how much body/power he has access to mirrors the entanglement pattern tracked elsewhere - influence that rises and falls with how much of a foothold the entity has

1987: Krang has genius-level intellect and is fully self-aware of it - believes himself superior to all; views the Turtles as minor nuisances, unlike Shredder's personal vendetta

1987: no empathy - recklessly endangers his own allies; sadistic, enjoys others' suffering

1987: deemed incompetent by his own kind (the Kraang Hive Mind specifically) - the stated reason for his banishment

1987: low self-esteem/submissive pre-android-body (implied trauma from losing his original body); reverts to megalomania once the body restores his size/power - power directly correlates to psychological state

2012: the Kraang cannot speak human language unassisted - they require a Kraangdroid unit to vocalize, and even then speak in redundant syntax, restating the subject "Kraang" at both the start and end of sentences

2012: no real individuality - all refer to themselves and each other only as "Kraang"

2012: vain - enjoy watching recordings of themselves in combat ("Turtle Temper"); sadistic - explicit preference for painful extraction methods "for fun" ("The Kraang Conspiracy")

2012: contrast point - Kraang Sub-Prime and Bishop (both Utrom-origin) have full independent speech and personality, what visibly separates "true" Utrom individuals from Hive Mind drones

2012: possibly asexual reproduction - a line in "Metalhead" implies no human concept of "mother"; they live for centuries or millennia like the 2003-series Utroms, and favor exo-suits over their natural crawling form

5. Powers, Abilities & Technology +

Krang's Intellect & Natural Form 1987 series

IQ of 968 (stated explicitly, "Venice on the Half Shell")

Machiavellian multi-step scheming, "thinks nine steps ahead"

Weakness: his own arrogance plus incompetent subordinates undermine his plans

Bodyless form: frail, slithers roughly 3 mph, weak physical attacks (slap/bite)

Same episode: shook an asteroid by stomping his robot foot in rage; damaged the Technodrome by banging on it

Android / Exosuit Body 1987 series

Large, bulky mechanical body; Krang rides in a torso cockpit

Originally had a molecular amplification chip for Godzilla-scale growth - destroyed in the suit's debut episode

Later "repaired" via a video game chip (Bebop/Rocksteady); Michelangelo hijacked it via the same game; amnesiac Shredder blew the whole body up; somehow repaired again by Turtles Forever

Ch'rell later co-opts the same growth tech, beats Krang in hand-to-hand combat in seconds

Hands shapeshift into weapons (axes, maces, pincers) and a communication device

Suit can grow jet wings instead of arms (used for a quick escape with Shredder, first appearance)

Krang swaps in different arm attachments kept in his personal quarters aboard the Technodrome

The Bubble Walker 1987 series

Krang's Bubble Walker

Krang's primary way of getting around before his android body existed - mechanical legs under a transparent protective dome, with holes for his tentacles to reach through and manipulate objects

This was the version used for the first Krang toy (Playmates Toys, 1990)

A "Four Musketurtles" flashback shows other Dimension X contemporaries of Krang's era riding Bubble Walkers too - it's not unique to him

The Krangazoids ride different-colored versions of the same walker in their debut episode (Section 6)

Krang pilots a much larger version of a similar walker body as a boss fight in the video game Teenage Mutant Ninja Turtles II: Back from the Sewers

The 2012 series' Kraang Walker weapon is essentially a much larger version of the same design - a quiet through-line between the two continuities

Source: turtlepedia.fandom.com - Bubble Walker

Kraang Technology 2012 series

WeaponsTri-shot pistol, Kraang Laser Blaster, Kraang Energy Cannon, lightning weapons, Kraang Walker, sub-spacial endoparticle disrupter, mutagen bomb

SuitsKraangdroids ("Normans"), flying Kraangdroids, Kraang Prime armor, Biotroid

RobotsFootbot Soldiers, Chrome Dome, Ms. Campbell

TransportKraang Floater, Kraang Scout Ship, the Technodrome, Trans-Dimensional Portal, Fast Travel Points, Portable Portals

EnergyPower Cell, Mutagen, power generator

MiscData storage device, Kraang Communication Orb, Kraang Neuro Switcher, torture prod, laser drill, mind-control pin, specimen-capture pods, mental energy extraction device

All Kraang tech is a corrupted version of original Utrom technology

In Summary

Krang's own gear - his intellect, his android body, his bubble walker - are personal, one-off inventions built around a single entity operating without a body of its own

The Kraang's technology catalog is the same idea scaled up to an entire civilization: an army's worth of suits, weapons, and portals built by a hive mind that also can't function on Earth without borrowed hardware

In both cases, the technology exists to give a bodyless, tentacled, other-dimensional intelligence a way to act physically in our world - the suits, the walkers, and the portals are all workarounds for something that doesn't belong here needing a foothold to operate

6. Major Story Arcs & Crossovers +

Plot Arc / Endgame 1987 series

Turtles banish the Technodrome (without Krang/Shredder) back to Dimension X

Krang/Shredder operate from an old science building afterward; Krang's android body damaged, forced to use a "bubble walker" on Earth

Technodrome destroyed for good in S8 "Turtle Trek" - engines destroyed, a monster plant drags it into a pit, portal destroyed, stranding everyone in Dimension X

2 years wandering Dimension X; abducted to Earth by Lord Dregg, who drains Krang's intelligence/life force; Shredder restores him; Dregg recaptures both; Turtles send Dregg and Mung back to Dregg's homeworld instead

Series finale "Divide and Conquer": Turtles retrieve Krang's abandoned android body from the ruined Technodrome to fight Dregg. Krang himself unaccounted for, presumed still in Dimension X

Turtles Forever, 2009 Crossover 1987 x 2003

Appears with 1987-Shredder in the 2003-series universe

His 2003-universe counterpart is a regular, non-evil Utrom - no evil counterpart exists there

Present when Ch'rell (2003 Utrom Shredder) is resurrected; initially likes him (physical resemblance), turns on him once Ch'rell hijacks the Technodrome and portal

Karai forcibly removes Krang from his android body, orders him to stand down

When Ch'rell betrays everyone, Krang joins 1987-Shredder and the Turtles (freed by Karai)

Ch'rell uses Krang's own growth tech; Krang matches it and fights him - only the 3rd time Krang ever takes his android body into combat - loses

Ending: Krang and Shredder plan to use a new "Giggle Ray" (Krang invention) on the Turtles once back in their own universe

The Krangazoids Episode 1987 series

"Invasion of the Krangazoids" (S7, 1993) is the source episode for Krang's original reptilian body, referenced in Section 1

Frustrated with unreliable help from Shredder and the mutants, Krang clones himself six times, creating the Krangazoids

The clones resist his orders, so Krang forces compliance by taking direct control of their bubble walkers

The Krangazoids turn out to be more dangerous than expected, using their bubble walkers' weapons to drive the Turtles into repeated retreats

The clones start developing hands of their own; one breaks free of its bubble walker entirely and runs off independently

Once they no longer need the walkers, the Krangazoids are free of Krang's control - and grow their own reptilian bodies, the same body type Krang lost before his exile

Newly bodied, they set out to conquer New York and remake it into a Dimension X-style environment

They build a thermal device underground aimed at turning the whole city into a volcano

Fully grown, the Krangazoids nearly turn on the Turtles, but end up arguing among themselves over who should rule Earth instead

The Turtles teleport the Krangazoids into the Technodrome and stop the volcano by flooding it with water

Threatened by his own clones, Krang offers to send them back to Dimension X - then secretly banishes them to a dimensional limbo instead, where they're left bickering over blame (see Section 2)

The Krangazoids - Species & Design 1987 series

The Krangazoids

Krang clones himself six times looking for help that's clever, sneaky, and brilliant - each duplicate is genetically identical to him but ends up with its own personality

The six: Blue (the most villainous), Yellow (a coward), Purple (vain), Dark-Green (gloomy), Light-Green (goofy), and Grey (the smart one)

Halfway through their transformation they keep Krang's brain-like head shape, but grow bulky bodies colored to match their own bubble walkers, with small red spines running down their backs and stubby arms and legs

Fully grown, they become tall reptilian bipeds with a long crocodilian tail, a row of dorsal spines, three-fingered hands, clawed feet, and fangs - the same body type Krang lost before his exile

The name "Krangazoids" isn't official in-universe terminology - the Turtles coin it themselves after watching six disembodied brain-clones unexpectedly grow into Krang's original lizard form

Donatello compares it to a lizard regrowing its tail, but since Krang himself never regrew his own body, the show treats it as a fluke of the cloning process rather than a natural ability of the species

Source: turtlepedia.fandom.com - Krangazoids

Krang <-> Kraang: The Direct Link 1987 x 2012

Krang (1987) and Kraang Sub-Prime (2012) are cousins

Sub-Prime banished Krang to the 1987 dimension for incompetence, for being "a screw-up"

"Trans-Dimensional Turtles" (2012, S4): Krang tries to redeem himself using three "dimensionizers" to destroy the 1987, 2012, and Prime realities simultaneously

Both Turtle teams, 1987 and 2012, stop him and expose the plan to Sub-Prime, who is furious - those are dimensions the Kraang collective had been trying to mutate for thousands of years

Krang tries justifying himself by citing Sub-Prime's own "wipe out the Turtles at any cost" order; Sub-Prime says that exact incompetence is why he was banished in the first place

Krang is beaten and re-banished to the 1987 reality

"Wanted: Bebop and Rocksteady": Krang returns with his dimension's Shredder to "Earth 7," recruits that world's Bebop and Rocksteady to power up the Technodrome and conquer the alternate dimension

This crossover is the single point where the two continuities directly interact - the Kraang collective's "thousands of years mutating dimensions" agenda is confirmed to include the 1987 universe itself

Timeline of Major Plot Beats 2012 series

Origin (shown retroactively, "Lone Rat and Cubs"): Kraang agents attacked Splinter while he held the not-yet-mutated baby turtles, causing the ooze exposure that created the Turtles

15 years later: Hive Mind begins kidnapping scientists via human agent Snake; targets include Kirby and April O'Neil - Turtles intervene, destroy a Kraang compound, mutate Snake into Snakeweed, rescue April - active enmity begins here

Turtle Temper: Surveillance-video conflict leads to civilian Vic mutating into Spider Bytez

Metalhead: Donnie reverse-engineers Metalhead from a scavenged Kraangdroid; Kraang later hack and turn it against the Turtles; reveals a Kraang plan to dump mutagen in the city water supply

Monkey Brains: Kraang funded Dr. Falco's mutagen experiments on Dr. Rockwell, creating the mutant psychic monkey; pulled funding later

The Gauntlet: Kirby O'Neil explains Kraang are dimensional aliens whose home universe has different physical laws, so Earth mutagen doesn't behave as intended for them - why they need human scientists

It Came From The Depths: Leatherhead gives the Turtles the Power Cell fueling the Kraang's dimensional portal

The Alien Agenda: W.G.P. front revealed; Kraang have DNA samples from every Earth species; Karai's interference exposes Shredder/Foot Clan to Kraang tech, sparking Shredder's later interest in weaponizing it

TCRI: Kraang reactivate the portal using the recovered Power Cell; bring Traag through; Turtles and Leatherhead fail to stop him; Leatherhead pulls Traag back through himself

Cockroach Terminator: Kraang retrieve a diamond lens for a laser drill meant to trigger a volcanic eruption in Manhattan

Enemy of My Enemy: Kraang Stealth Ship hunts the Turtles; ship destroyed, one pilot captured by Shredder

Karai's Vendetta: The captured Kraang reveals under threat that the Turtles are protecting April, "whom they need for their plan" - triggers Shredder's own hunt for her as bait

The Pulverizer Returns!: Captive Kraang admits mutagen is unstable/unpredictable on Earth, and that Kraang and Shredder now share a common enemy in the Turtles

Newtralized!: The Newtralizer calls the Kraang "the most insidious aliens in the ten dimensions"; Kraang test the Kraang Walker weapon; Newtralizer hijacks it; Casey Jones, the Turtles, and Slash destroy it

Annihilation Earth!, Parts 1-2: Bishop leads an assault on the sunken Technodrome where Kraang Prime and Sub-Prime are hiding/repairing it; the Triceraton fleet arrives and completely destroys Earth, all Kraang and human inhabitants, using the Heart of Darkness - only the Turtles, April, and Casey survive, rescued by Zayton Honeycutt; Triceratons leave satisfied the Kraang threat is crippled

Beyond the Known Universe: Recap: the Kraang/Triceraton war began when the Kraang wiped out the Triceraton homeworld using a Black Hole Generator

The War for Dimension X: Turtles and Fugitoid seek the Black Hole Generator pieces from the Utrom; Kraang Sub-Prime kidnaps their Queen, triggering war; the Utrom win and seize Sub-Prime's base

Earth's Last Stand: Sub-Prime and Kraang droids buy the Heart of Darkness from Zayton Honeycutt - confirms the Kraang didn't build that weapon, just weaponized it

Tokka vs. The World: TCRI seized by the Earth Protection Force; Kraang tech converted to Utrom tech; surviving Kraang shown in containment, in a meditative state

Tale of Tiger Claw: Flashbacks confirm the Kraang mutated Tiger Claw and his sister Alopex

In Summary

Across every era covered in this section, the shape repeats: an exiled or hive-bound intelligence tries to remake Earth into a copy of its own dimension, always working through borrowed bodies, borrowed allies, or borrowed hosts

Every attempt ends the same way too - banishment, containment, or defeat - only for the next crossover, the next clone, or the next cousin to pick the thread back up somewhere else

The Krang <-> Kraang link confirms this isn't two coincidentally similar stories; it's one extended family, and one extended campaign, spanning continuities

7. The April O'Neil Connection +

The Breeding Program 2012 series

April O'Neil is a human-Kraang mutant hybrid - the end result of a multi-generational Kraang breeding program designed to stabilize mutagen in Earth's dimension

Mrs. O'Neil, April's mother, is also a human-Kraang hybrid - disappeared from April's life when April was 6

The Hive Mind made a rejected clone of Mrs. O'Neil at some point

April is "uniquely attuned" to Earth's universe because of this bred lineage - why the Kraang need her specifically, not just as a hostage

Kirby O'Neil and teenage April were both kidnap targets early in the series - the inciting incident for the whole Turtles-vs-Kraang conflict

"The Alien Agenda": Kraang obtain a sample of April's DNA via the W.G.P. front, send Ms. Campbell to kidnap her

"TCRI": a decoded Kraang data storage device reveals the Hive Mind are searching for April specifically

"The Kraang Conspiracy": a Kraang says harmful DNA-extraction methods on April would be "more fun" than taking a hair sample

"Target: April O'Neil": a full episode built around her as the Kraang's target

"Operation: Break Out": Kirby O'Neil is mind-controlled and held hostage to lure the Turtles into the Kraang lair - April's family used as bait twice, father then daughter

April Android - Krang-Built Duplicate Fleetway comics

April Android, the Krang-built duplicate from Fleetway's UK comics

A different continuity from the 1987 and 2012 shows above - this is the Fleetway UK comic line - but it uses the same name, Krang, and the same instinct: build a fake April to get to the Turtles

A robot disguised as April O'Neil was built by Krang to infiltrate and destroy the Turtles

Shredder and two of his mutants kidnap the real April; the android takes her place

April Android steals the Channel 6 news van, finds the Turtles, and lies that Shredder has been spotted across town to lure them into a Footbot ambush

When the Turtles destroy the Footbots anyway, she moves to Plan Two - cuts the van's brake lines, causing a crash the Turtles survive thanks to their shells

The crash tears part of her synthetic skin, exposing her as a fake

She proves very strong in the fight that follows; Leonardo cuts her in half with his katana just as she's about to smash three of the Turtles

Trivia: despite being called "April Android," a female-presenting robot is technically termed a "Gynoid"

April Clones - Kraang Breeding Experiments 2012 series

The April Clones lineup, "The Kraang Conspiracy"

Introduced in "The Kraang Conspiracy" - the same episode where a Kraang calls painful DNA extraction from April "more fun" (above)

The clones need the real April's DNA to be complete/stable

Most clones turn into black slime once killed

Reject clones are deformed, failed prototypes - the named example is "April Derp"

One clone easily fools the Turtles, traps them in a detention cell, and attacks them; Donnie realizes she's fake and defeats her, turning her to black slime

The Turtles then discover many more April clones incubating in mutagen

The Kraang release the rejected clone, April Derp, to attack the Turtles while the real April's DNA is being extracted; April kills April Derp with a large energy blast

The encased clones are then released and try to pass themselves off as the real April; April proves her identity by drawing her tessen and kills two of them; the Turtles finish off the rest

Source: turtlepedia.fandom.com - April O'Neil (clones) (2012 TV series)

Wasp (Bee) April O'Neil has been a wasp herself:

April mutated into a giant wasp

1987: in "Revenge of the Fly," Baxter Stockman shoots April with a mutagen gun that transforms her into a giant wasp - one of several brief mutations April undergoes across the series, each reversed by the episode's end

The Giant Wasp dimension

2003: in "April's Artifact," an interdimensional device belonging to April's Uncle Augie accidentally transports April and the Turtles to a jungle dimension inhabited by giant wasps with paralyzing stingers

2003: the group finds the wasp colony's nest and narrowly escapes the massive Wasp Queen; they return to the same dimension in "Trouble with Augie" while tracking down Augie, and destroy the interdimensional device on their way out

The Cube - A Multiverse Transporter

The Transport Artifact - April's puzzle cube

The device itself is a puzzle cube left behind by April's father; twisting it into the right configuration opens a doorway to a specific other dimension, keyed by whatever coordinates are set

In "Trouble with Augie," April and Donatello use the Cube to follow a distress signal to a new dimension, where they find Augie alive inside a futuristic city ruled by a reptilian race calling themselves the Brotherhood

The Brotherhood present themselves as peaceful, but are secretly forcing Augie to repair their own Transport Artifact so they can open a permanent doorway to Earth and eat humanity

April reprograms the Cube to escape through the Wasp World instead of straight to Earth - and has Donatello rig the Brotherhood's own Transport Artifact with explosives set to detonate right after they teleport out

The Brotherhood follow them through to the Wasp World just as the sabotage goes off, permanently destroying that Transport and trapping the Brotherhood's invasion force there with an angry wasp colony - they don't survive it

April, Augie, and Donatello escape safely back to April's antique shop, and Augie is reunited with his family after years missing

Source: turtlepedia.fandom.com - Giant wasps; Transport Artifact; Trouble with Augie

The Parasitica Wasp, a Kraang lab creation

2012: the Parasitica Wasp is a mutant created directly by the Kraang - born when they poured mutagen on a parasitic wasp during arthropod experiments in one of their labs

2012: it escapes and turns on the Kraang before the Turtles find it in the secret lab; in the fight it stings Leonardo, infecting him with a mind-control virus that makes him protect its egg instead of destroying it

2012: more Parasitica Wasps later turn up as detained prisoners inside a Kraang holding base in "Metalhead Rewired," alongside other mutants the Turtles had previously fought

Source: turtlepedia.fandom.com - Parasitica Wasps (2012 TV series)

Multiverse

April O'Neil, alternate Earth ("Elementary, My Dear Turtle")

1987: in "Elementary, My Dear Turtle," an alternate-Earth April appears in a world under the control of James Moriarty; unaware the Ninja Turtles even exist, she's part of a resistance movement working to overthrow his regime

She gives a hungry Michelangelo an apple during their encounter

Once Moriarty is defeated and the timeline is restored, the "real" April - back on the main Ninja Turtles Earth - finds an apple in her bag with no memory of how it got there

This kind of alternate-timeline crossover isn't unique to April - TMNT revisits the multiverse concept repeatedly across the franchise

Another example: the Super Turtles (Mirage comics) are an entirely alternate-reality version of the four Turtles, from a world where a corrupt politician named Lucks fabricates an alien threat to seize global control; that world's April/Casey counterpart is Neil O'Malley, a male version of the character

The Super Turtles eventually turn against their world's Shredder-equivalent, Doctor Shreddarius; in a later story they're shown being watched by "an Utrom scientist looking into their world from the standard TMNT universe" - another quiet Utrom/multiverse thread

A Separate Continuity Worth Flagging

Ninja Turtles: The Next Mutation, 1997-98

Right after 1996 - the timing matters here - a short-lived live-action series called "The Next Mutation" premiered in September 1997, following directly on the heels of the original 1987 series' run

It was marketed at the time as a continuation of the 1987 series, but plays out in its own separate continuity - a real-world example of the same "which timeline is this" pattern seen in the fictional crossovers above

Its biggest new addition was a fifth mutant turtle - Venus de Milo - the franchise's first female turtle, alongside a new central antagonist group, the Rank, led by Dragon Lord

Lasted only one season, 26 episodes, before cancellation; a planned second season - reportedly set to finally bring April O'Neil and Casey Jones into this continuity - never happened

Source: turtlepedia.fandom.com - April O'Neil (Elementary, My Dear Turtle) (1987 TV series); Super Turtles (Mirage); Ninja Turtles: The Next Mutation (TV series) The "Prime" Naming Pattern

"Prime" shows up repeatedly across this franchise's multiverse content - Kraang Prime as the leader of the whole Hive Mind (Section 1), and the "Prime reality" explicitly named as one of three universes targeted in the "Trans-Dimensional Turtles" crossover (Section 6), alongside the 1987 and 2012 realities

That word choice isn't unique to TMNT - "Prime" is a standing convention across pop culture for marking the "main" or original timeline out of a set of alternates (Earth-Prime, Optimus Prime, and so on), so its repeated use here reads as another quiet multiverse marker baked into the naming itself

The Throughline

April is not incidental to the plot - she is the biological key and culmination of the entire Kraang mutagen-stabilization program

Nearly every major Kraang arc either revolves around acquiring her or leveraging her family as leverage against the Turtles

That same instinct - build or grow a fake April to move against the Turtles - shows up twice more outside the core breeding-program storyline: once as a robot (Fleetway) and once as a lab-grown clone batch (2012)

April isn't just the breeding-program's endpoint - she's also where the other threads in this piece physically converge: her own wasp mutation, the Cube's reptilian/Earth-invasion plot, and the alternate-Earth crossovers all orbit her specifically, not the Turtles. She's less a side character in the pattern than the connective point for most of it

8. Trivia & Continuity Notes +

Trivia 2012 series

Fans originally assumed the Kraang were an amalgam of the 2003 Utroms and 1987 Krang - later clarified as a faction of Utrom brainwashed by Kraang Prime, a mutant Utrom

Voiced by Nolan North (also voiced Raphael in the 2007 CGI film)

"Exterminate! Exterminate!" in "The Invasion, Part 2" is a direct Daleks / Doctor Who nod - shared traits: tentacles, brain-like appearance

Kraang human disguise resembles Agent Bishop's look from the 2003 series

Conclusion

Strip away the show-by-show detail and the same shape holds across all eight sections: an intelligence exiled from - or native to - another dimension, without a stable body of its own, reaching Earth through a Technodrome or portal network. Shredder, in both versions, is the earthly power that hosts and enables it - a body, a base, a foothold, in exchange for its technology, expendable once his usefulness runs out. The Kraang's loss of individuality, everyone speaking only as "Kraang," lines up with how this blog's sources describe the Lurker itself: entities stripped of identity that merge into one undifferentiated mass. Every arc, every era, repeats the same pattern too - an exiled or hive-bound intelligence trying to remake Earth into a copy of its own dimension through borrowed hosts, always ending in banishment or defeat, always picked back up by the next clone, crossover, or cousin. And April O'Neil sits at the center of nearly all of it - not just the breeding program's endpoint, but the connective point where the wasp theme, the Cube's reptilian Earth-invasion plot, and the multiverse crossovers all converge on her specifically. Individually, these are TV and comic-book trivia. Read through the Lurker lens this piece opened with, they're the same pattern this blog keeps finding everywhere else.
