Max about Dr. Colosso

He is a former supervillain who was turned into a pet bunny by his archenemy Hank. He lives with the Thundermans and is Max's sarcastic pet bunny.

Dr. Colosso is voiced and portrayed by Dana Snyder.

Biography

Dr. Colosso was born and raised in Metroburg. He became a powerful supervillain by creating dangerous gadgets but was eventually stopped by Thunder Man.

Despite being defeated and turned into a bunny, Dr. Colosso did not abandon his evil ways. He continues to consider himself a supervillain. During Max's evil phase, Dr. Colosso quickly became Max's friend and coached him to become a supervillain. He "hates" the rest of the Thundermans and looks for every chance he gets to mock them.

The Thundermans

In Adventures in Supersitting, Dr. Colosso met Nora and Billy for the first time when they went into Max's Lair. Dr. Colosso and Nora scream before he asks to close his cage.

In The Weekend Guest, Dr. Colosso was swallowed by Phoebe's Venus Fly Trap plant but the Thunder Twins saved him.

In Phoebe's a Clone Now, Dr. Colosso taught Max how to make clones of people. When Max figures out how to, he made one of Dr. Colosso and shows it to Phoebe. Max shows Phoebe her clone and claims he made it to work with her work load but actually wanted to use as a way to get into Villain University. When a book falls on Clone Phoebe, Dr. Colosso reminds Max the first role of cloning is not to hit the clones on their head or else they go dumb. He demonstrates by hitting Clone Colosso. This scares Max because the dumb clone Phoebe is more likely to screw things up at the library.

Later on, Barb and Hank send Clone Phoebe and Clone Colosso to Aunt Maggie's Farm but mistakenly sent the real Colosso instead of the clone.

In Pretty Little Choirs, Dr. Colosso got kidnapped by Darcy Wong after she discovered that he could talk. She tortured him to get him talking to prove that the Thundermans was weird but she wasn't successful. In the same episode, he told Nora and Billy that he hates it when they dress him up without letting him choose the costumes.

In Haunted Thundermans, he sneaked into Max's backpack so that he can go to New Orleans with the Thundermans. When the Green Ghoul possessed Phoebe and asked Max to join, Dr. Colosso persuaded Max to accept the offer but Max refused.

In Blue Detective, Dr. Colosso became so jealous of Max and Maddy that he stole one of Max's blue beans and turned Max blue. When they later figured out it was him, he admitted that his only crime was loving Max ... plus all his other actual crimes.

In One Hit Thunder, Hank and Barb asked Nora and Billy to be nice to Dr. Colosso instead of stooping to a supervillain's level. The whole family tried being nice to him but he made their lives miserable. He told them he hates it when they're nice to him. He likes them to mistreat him because he's a supervillain and has nothing else to live for.

However, on arrival, he found that King Crab, Lady Web and Scalestro lied about the award and the speech. They had lured him to kick him out of the league because he hadn't done anything evil in years. To save himself, Dr. Colosso betrayed Max and turned him into the other villains, saying that he had captured the son of Thunder Man. However, after looking at a selfie of him and Max, he felt guilty and went back to help Max. King Crab tied him up together with Max so that they can be eaten by the hermit crabs. They were later saved by Phoebe. Dr. Colosso turned back to a bunny because of the timer Max had put on the Animalizer.

In Are You Afraid of the Park?, Dr. Colosso needed to make some money to repay Hank the money he charged to Hank's credit card while playing Candy Squash online. So, he started running an unauthorized cereal business, selling a cereal called "Colosso's." He made enough money to pay the debt and got a surplus. However, his website got shut down by the Federal Bureau of Cereal Investigation. They said the cereal business was illegal and the raisins weren't really raisins. The Thundermans had to pay the fine.

In He Got Game Night, Dr. Colosso helped Max cheat the wheel of prizes so that it will land on a new car during the family game night. But Max turned on him so that he can partner with Allison. Dr. Colosso became jealous of Allison. Phoebe then turned him into a human to be her game night partner. He came in and introduced himself as "Uncle Colosso."

Unfortunately, Dr. Colosso quickly brought chaos into the family leading into an epic pillow fight. When Allison left, Barb quickly turned Colosso back into a bunny. Colosso then went outside and started eating away Allison's tires.

In Thundermans: Secret Revealed, Dr. Colosso gave Max the tuxedo he wore to evil prom with Octopus Girl. He was happy when Dark Mayhem finally called to give Max an opportunity to become a full supervillain. He tried to advise Max to use the orb to steal Phoebe's powers but Max was reluctant about it. Dr. Colosso was taken away from Max as a punishment for working with Dark Mayhem. However, he managed to escape and help Max out of the lair. Later, during a call with Dark Mayhem, Dr. Colosso realized that Dark Mayhem really hated him and would destroy him if he took over Hiddenville. So, he helped the Thundermans escape the house just before Dark Mayhem's attack.

Candi Falconman and Dr. Colosso

Colosso with Candi

In Thundermans: Banished!, Dr. Colosso is still upset that Max chose good over evil. When the Thundermans are sent to Antarctica, he stays behind but soon realizes his new roommate, Candi Falconman, wants to control people in Hiddenville. To stop her, he secretly calls Max and Phoebe for help while pretending to cooperate, and later aids the Thunder Twins by eating away the cotton candy that binds them.

Since Max stopped being evil, Dr. Colosso's life has been tough. In Smells Like Team Spirit, he complains about being fed gross succotash and manipulates gullible Billy into stealing fresh vegetables from others, claiming he planted them. Nora and Chloe help Billy realize he's being tricked, and they scare Colosso by pretending the cops are coming. When he tries to escape, Chloe, dressed as a police officer, catches him.

Without Max, Colosso now has time to speak to his mother. In Max to the Future, he spends most of his time on a call with his mother. He later helps Max to fake crimes to make Max's CrimeCaster look good. Unfortunately, he gets busted by Phoebe when he forgets and takes a call from his mother. In Parks & T-Rex, he even fakes being sick just to trick Max into hanging out with him. Max later finds out and promises to spend more time with him.

Following Allison's breakup with Max in 21 Dump Street, Dr. Colosso stays by Max's side, laying on the couch and eating pizza with him. However, when Molly sees him, she blames Max for mistreating a bunny by feeding him unhealthy food. So, she steals him for the Green Teens Pet Adoption Fair. Colosso is adopted by Principal Bradford, forcing Max and Phoebe to sneak into their school at night and steal him back.

Dr. Colosso, still mad at Max for turning good, seeks revenge on him and Phoebe whenever he can. In Z's All That, he withholds information about the Li'l Z Program, putting them last in rankings. He later helps Nora boost her powers to confront them for replacing her with Billy. In Nowhere to Slide, he sabotages their boys' and girls' nights after being ditched, and in Rhythm n' Shoes, he hacks Phoebe and Cherry's rhythm shoes to ruin Cheyanne's performance, retaliating against Max for taking credit as DJ Colosso.

Colosso's stay at the Thundermans' home is jeopardized in Make it Pop Pop when Pop-Pop Thunderman discovers Max is hiding the supervillain and throws him and Colosso into the Detention Zone. Phoebe attempts a rescue, but it’s Colosso who saves them by revealing the twins are Sergeant Thunder's grandkids. He escapes with Max and Phoebe, who convince their grandfather that Colosso is improving due to their influence, only for Colosso to insult Pop-Pop and get knocked out by him.

Colosso crashing the wedding

Dr. Colosso planned on using the Animalizer on Thunder Man and Electress because they had stopped his wedding at the Oval Office before. He crashed Hank and Barb's wedding and at first, Hank mocked the gadget, claiming that none of Dr. Colosso's inventions really work. Colosso then used the animalizer to turn Barb and Hank into goats and swore that he would never let Hank and Barb have a successful wedding. The Hero League later found a way to turn Hank and Barb back into humans.

After that, Hank went after Dr. Colosso and used the animalizer against him, turning him into a bunny that Max takes care of. Dr. Colosso has been reverted back to human with the Animalizer multiple times, but each time is transformed back to a bunny afterwards.

In A Hero Is Born, Max uses the animalizer on Colosso and goes with him to the Villain League Headquarters in Metroburg where Dr. Colosso is to receive a villain award. When they arrive, however, King Crab kicks Dr. Colosso out of the Villain League because hasn't done anything evil in years. Colosso explains he has been busy capturing the son of Thunderman. King Crab thanks him and hangs Max above a vat filled with hungry hermit crabs, slowly lowering him. When Colosso takes out Max's phone for a selfie with King Crab he sees his selfie with Max and gets emotional. He apologizes to Max and tries to help him, but King Crab hangs him next to Max. Finally Phoebe arrives and saves them both. Colosso automatically turns back into a bunny, because Max had set a timer on the animalizer.

In He Got Game Night, Phoebe uses the animalizer and turns Colosso human. He presents himself as Uncle Colosso at the family's game night with the intention to take down Max who had ditched him to team up with Allison.

The Thundermans: Undercover

In Thundercover, Dr. Colosso is contacted again by the evil transmission on the Thunder Monitor who told him to sneak with Phoebe, Max and Chloe to Secret Shores. In their Hi-Tech Beach Home, the evil transmission tells him to find the key card to the Hero League weapons fault located in the house and is promised he will be turned human again. Dr. Colosso finds it and the evil transmission lies to him and takes a screenshot of the key card to make a 3D replica. Phoebe and Max find out and Thunderford reveals that Malware was who was contacting Dr. Colosso. When Phoebe, Max and Chloe stop him, Dr. Colosso is put in house arrest for helping him.

Personality

Dr. Colosso, a former supervillain and current prisoner of the Thundermans, remains inherently villainous despite his current rabbit form. He is mischievous, harbors a deep-seated resentment towards the Thundermans, and frequently assists Max with his evil schemes. Due to his unpredictable nature, Dr. Colosso is notoriously untrustworthy, often betraying allies, including Max. His personality is marked by sarcasm and outspokenness, which he employs liberally in most situations.

Beneath the surface, Dr. Colosso exhibits unexpected vulnerability. He can be surprisingly soft and emotional, particularly when seeking Max's approval or attention. He also displays a strong desire to regain his human form and demonstrates a degree of clinginess towards Max in his pursuit of this goal.
