Mutagen Man

Mutagen Man Lrg 54f6aec73a102


Mutagen Man is an enemy of the Ninja Turtles. Formerly an annoying fanboy of the Ninja Turtles known as Timothy, he is now a mutant blob after the Mutagen was tested on him by The Foot Clan, which was something Shredder wanted after The Kraang provided him with Mutagen, which leads to him later on staying inside Donnie's Lab. He gained arms and legs thanks to the Mutagen he was consuming, but he is currently frozen due to a failed sample of Retro-Mutagen and Donatello is trying to cure him from his mutation. Mutagen Man debuts in The Pulverizer Returns!.


When the Shredder wanted to test the Mutagen on one of his Foot Soldiers, he wanted a volunteer to test it on. So for this experiment, he chose Timothy, who had became part of The Foot Clan recently. Dogpound and Fishface took him to a place where the mutation was to take place, but Donatello followed them, who then was followed by the arrival of Leonardo, Raphael, and Michelangelo. Donnie tried to stop him, but when they were distracted, Timothy spilled the Mutagen on himself, mutating him into something he didn't expected. He mutated into a blob known as Mutagen Man.

  • Michelangelo came up with the name "Mutagen Man" due to him being a blob and having the ability of consuming Mutagen.
  • Like The Kraang, he speaks in a third-person point-of-view.
  • Mutagen Man turned into a blob, maybe because he didn't touched nothing before the mutation, only that he was touched by Donatello and Dogpound but only on his suit.
  • In Mutagen Man Unleashed, he was frozen by the failed sample of Retro-Mutagen when accidentally defeated by Donatello.
  • Mutagen Man can release Mutagen out of his hands, which is acidic.
  • Unlike his 1987 incarnation, he is a villain of the Ninja Turtles, not an ally.
  • The speaker box that was made by Donatello for Mutagen Man belongs to a brand known as "Laird".
    • This is a reference to Peter Laird, who was one of the creators of the Teenage Mutant Ninja Turtles.
  • The blob that forms his body might be stomach acid.
  • In The Invasion Part Two, Donatello had to leave him back in New York City.

    • I honestly have no idea. I bet it was because Leo new arch enemy is the Shredder. Because Shredder was the one to hurt Leo in the first place.
    • My, this has been open a while. I would say that the upcoming episode summaries indicate that there may be something developing as far...
