As The Pulverizer

As human

The Pulverizer: Months after seeing them for the first time, "The Pulverizer" meets the Turtles in person. When he attempts to stop the Purple Dragons, he is quickly outmatched and the Turtles come to his rescue. They succeed in saving his life, but his attempts to help them fight results in the gang escaping with their stolen loot.  The Turtles try to ditch "The Pulverizer", but the tails of his mask get caught in the door of the Shell Raiser as they drive away. They unwittingly drive him back to the lair, but fortunately for them, he blacked out most of the way and didn't see how they got there.  Still oblivious to the fact that the Turtles are mutants, as well as the fact that they don't want him in their lair, "The Pulverizer" quickly becomes a nuisance. He does, however, give them a clue as to what the Purple Dragons stole and why. However, they leave "The Pulverizer" behind with Donnie. After trying to ignore him for a while, Donnie tries to teach the overeager and overweight hero wannabe some basic self-defense moves with little success. In the middle of the training after the Donnie teaches him how to knock people over (where he fails horribly), Mikey calls and tells him about the situation with Raph. Donnie asks the Pulverizer to drive the Shellraiser while he makes an antidote for Fishface's venom. Before they reach the building, they reach a roadblock, which Donnie forces him to jump. When the Kraang stole the power cell, Pulverizer tried to help out the turtles, but failed miserably. Donnie had to help him, and missed his chance to get the power cell. In the end Pulverizer promised to get better and hoped to see the turtles again.

Pulverizer Returns: The Turtles see a ninja trying to break into the T.C.R.I. building. When they go down to stop him, they discover that the ninja is in fact just The Pulverizer in a Foot Clan uniform. Pulverizer tells the Turtles that foot hired him to draw all the fire away from other Foot Soldiers. He later decides to be a spy for the turtles to get information for them. He managed to let them know that Shredder was using mutagen to build an army. Later when shredder was testing the mutagen, Pulverizer, real name Timothy, decided to volunteer so he could help out the turtles, but the Turtles knew the results were dangerous and set out to rescue him. Donnie tried to help him and warn him the dangers of the mutagen, but with the Foot, Fishface, and Dogpound surrounding them, Pulverizer wanted to help and poured mutagen all over himself. However, he learned how deadly it was as he began to feel a burning pain from the mutagen, thus mutating into a 6-foot-tall living blob of mutagen with exposed organs.

The Noxious Avenger: He is mentioned by Muckman as corroboration for his lie to Joan Grody that the Turtles don't exist.

As Mutagen Man

Pulverizer Returns: When mutating into Mutagen Man, from pouring mutagen on himself, Timothy lost control of himself and went on a rampage. Dogpound set a bomb and took Fishface and the Foot soldiers and fled the warehouse, locking Mutagen Man and the turtles in as the countdown started. Mutagen Man was still on the rampage, but the turtles managed to calm him down for a brief moment. The young mutant then saw in a reflection the monster he had become and then lost control again.. Eventually Donnie managed to come up with a plan that would trap him in a glass container and then he and his brothers drove out of the warehouse on the stealth bike just before the warehouse exploded. The mutated Pulverizer was last seen at the turtles lair, where Donnie promises him to somehow find a way to reverse the process and get him back to a human.

The Mutation Situation: He is seen for a brief period of time. He is seen, being tapped by Mikey in the lab.

Invasion Of The Squirrelanoids: He, again, has only a brief cameo.

Mutagen Man Unleashed: Timothy appears as the main villain in this episode as he drinks some ooze, gets new powers, and goes on a rampage after April O' Neil. He is defeated in the end by Donnie freezing him with the faulty Retromutagen. Donnie still promises that he will try to make Mutagen Man human again.                           

Mikey Gets Shellacne: Timothy appeared in the background in some scenes that take place in Donnie's lab.

The Kraang Conspiracy: He appears frozen in the background of Don's lab when April finds out she is a mutant.

Metalhead Rewired: He makes a cameo frozen in the background of Donnie's Lab.

Of Rats and Men: He made another cameo on this episode.

The Invasion: In Part 2, Donnie says goodbye to Timothy one last time while he was packing up one of his beloved goods with him and moving to the Woods.    

The Deadly Venom: He is again seen in Donnie's Lab.


As a human, Timothy had brown hair, brown eyes, was overweight, and around Donnie to Leo's height and had skimpy legs, despite his size. He wore a costume based on the turtles covering from head to toe, except for his face, with a belt that had the letter P on it (similar to the 1987 style), and wore a red mask. He wore a foot uniform when he was in the foot clan.

As Mutagen Man, Timothy is a green blob, from touching the mutagen, with two long tentacle arms. His brain and vital organs are visible in his body. His eyes and mouth can be extendable. He was originally trapped in a mutagen container stashed in Donnie's lab, but in Mutagen Man Unleashed he kept drinking mutagen while Donnie tried to find a cure for April's dad, which eventually mutated him further and allowed him to grow powerful acidic arms and legs and the ability to regenerate, but now he can't move at all unless he has mutagen inside of him.

He is currently frozen by an unstable type of mutagen.


"The Pulverizer" is the Turtles first ever fanboy and a wannabe superhero. He first saw them when they fought Baxter Stockman on the roof near his apartment in I Think His Name Is Baxter Stockman. Thinking the Turtles were crimefighters in turtle costumes, he decided to become one himself. Making his own turtle costume and calling himself "The Pulverizer", he set out to become a hero. However, he does not have any fighting skills at all. He doesn't understand the time and commitment needed to become a hero or a ninja. He is looking for the fast track to be a hero "now". He pads his costume to simulate muscle as it is "faster than working out". He is under the delusion that a costume and witty banter is all it takes to be a hero but is sorely mistaken (emphasis on the sorely part). He is overweight, lazy, arrogant, impatient, and undisciplined. All in all a typical teenager. Despite his flaws, Pulverizer/Timothy has a good heart and has good intentions, but his rash attitude always gets him into trouble.

When he was turned into a mutant, Timothy became violent, feral, and mindless. He would randomly lash out at people trying to either get help or out of a lack of control. But was able to be calm down by Donnie, who promised to turn him back into a human one day. But then one day Pulverizer drank some ooze and grew arms and legs and went on a violent rampage to find April until he was frozen by Donnie. He hates The Turtles because he blames them for turning him into a mutant blob in a tank despite the fact it's his fault and not the Turtles.
