This section covers the Turtles characters from the 2003 series. For the two-part Japanese OAV series, see Mutant Turtles: Chōjin Densetsu Hen.
The Super Turtles are alternate universe versions of the Teenage Mutant Ninja Turtles.
The Super Turtles were originally designed by Peter Laird in 1993, but their designs went unused for nine years until 2002, when they appeared in the Mirage Comics, Teenage Mutant Ninja Turtles volume 4, issue 7. The Super Turtles later appeared in the 2003 series episode Reality Check, interacting with a denizen of the standard Teenage Mutant Ninja Turtles universe, Michelangelo. The Super Turtles' origin is told in Tales of the TMNT Volume 2, issue 47.
The exact origin of the Super Turtles' powers remains unexplained in the 2003 animated series. In their alternate dimension in which superheroes are a common thing, the Turtles were initially trained by Sliver until the day they lost him....to evil. Sliver eventually turned into a mad, evil mastermind whom his former foster sons pledged to stop at all costs while Sliver in turn is willing to do anything to get his sons back to him. In this dimension, April O'Neil was the mayor of New York City (here called Megatropolis) and working with the Super Turtles on a professional basis, with Casey as her bumbling and mild-mannered right-hand man.
When the Ultimate Ninja and Drako, both fused into one entity, used the combined War Staff and Time Scepter to banish the Ninja Turtles into different realities and futures, Michelangelo ended up inside the Super Turtles' headquarters, the Shell of Justice, where he caught his counterpart brothers in an exercise simulation. After thoroughly checking Mikey out and hearing his (somewhat incoherent) story, the Super Turtles were at a loss as how to send him back to his own reality when Mayor O'Neil showed up to inform them of the Sliver's newest threat: the Penultimate Nullificator, a doomsday device set to eradicate all life on Earth, with the exception of anyone inside Sliver's headquarters. Mikey joined the Super Turtles in their exploit, only to learn to his horror the true identity of the Sliver. The Super Turtles and Mikey were then overpowered by the Sliver as locked inside a cage made of Utromidium, the only substance capable of neutralizing their powers.
In this dire situation, Mikey had the decisive idea: upon his suggestion, Blobboid turned into Mikey and professed his loyalty to Sliver, tricking him into letting him out. Then Blobboid snatched Sliver's control cane and released Mikey and his brothers, whereupon they attacked Sliver and trapped him inside his own Utromidium cage. With time ticking down on the Nullificator's timer, and him beginning to phase out of this dimension, Mikey provided another vital idea, which made Shellectro reprogram the timer so the device would destroy everything inside the tower only. Then Mikey disappeared, and the Super Turtles escaped just moments before the Nullificator activated, taking Sliver and his tower with it. In recognition of Mikey's achievements in their final fight, the Super Turtles erected a statue of him in front of the Shell of Justice in his honor.
The Super Turtlesconsist of:
- Graviturtle (formerly known as 'Captain Gravity' in Laird's 1993 sketches) - Graviturtle is the counterpart of Leonardo. He acts as the leader of the Super Turtles and has the gift of gravity manipulation, which he controls through his whip as a focus.
- Shellectro (formerly known as 'Electroboy' in Laird's 1993 sketches) - Shellectro is an alternate version of Donatello. He has the talent to produce electrical discharges that he can fire as lightning or even use to fly. He is also able to manipulate electrokinetic electricity flows.
- Griddex (formerly known as 'Grid' in Laird's 1993 sketches) - Griddex is the superhero version of Raphael. He has super strength and is able to change his size; with these characteristics, he works as the muscle man of his team. Usually, Griddex is in giant form while in battle.
- Blobboid (formerly known as 'Mr. Blob' in Laird's 1993 sketches) - Blobboid is the superhero version of Michelangelo (even though he tried to deny this in the 2003 show). His body has a slimy consistency which allows him to change his shape and his appearance at will, to stretch his limbs and to pass through attacks by itself.
- In the 2003 series, the Super Turtles are (in a way) humorously hinted at in The Unconvincing Turtle Titan when Michelangelo designs a set of superhero costumes for himself and his brothers and the latter show their "appreciation" by garbling the names of well-known comic superhero teams.
- In the 2003 animated episode "Reality Check", the Super Turtles characters are voiced by the same voice actors of their respective Ninja Turtle counterparts.
- In the 2014 action film produced by Michael Bay, the history of the Turtles is similar to the Super Turtles in the following ways:
- That they were test animals for a preparation, which should bring its creator financial and political gain;
- That the Turtles possess (to some extent) superhuman strength;
- That one of the primary antagonists (Eric Sacks) just like Lucks is playing to the facade of honor;
- And that the Shredder (similar to Shreddarius) uses a high-tech suit of armor.
