Justin Is Short

Leonardo Looking At Justin


Justin is an enemy of the Ninja Turtles. He is a gigantic mutant that was created with the Mutagen by Karai via mixing numerous samples of animal DNA into one hybrid mutant. Even though he might look innocent, he is actually a dangerous mutant with electric eyeballs. Justin debuts in The Alien Agenda.


In a Kraang Lab, the Ninja Turtles and Karai were fighting versus The Kraang. Then when Karai curiously and purposely pressed a button, a bunch of animal DNA samples went into the Mutagen. The DNA samples fused and formed a mutant known as Justin.
