I'm being evil. Isn't that what you wanted? Aren't you scared, boo-hoo?
~ Dr. Negative
Too long have I suffered living between you two ninnies! But now, NOW as Dr. Negative, I shall finally exact my exquisite revenge!!
~ Dr. Negative

Doctor Negative is an enemy of Mermaid Man and Barnacle Boy whom Squidward cosplays in the episodes "Mermaid Pants" and "Appointment TV".  He wears a white coat with a red circle-backslash symbol, a black eye mask, and a head mirror.

He is voiced by Rodger Bumpass.

History

Dr. Negative is first mentioned in "Mermaid Pants" by SpongeBob and Patrick during their game of pretend superhero, with the duo calling themselves Mermaid Pants and Barnacle Star.  They notice Squidward and call him Dr. Negative, much to Squidward's annoyance.  After Mermaid Pants and Barnacle Star destroy Squidward's garden and eat his vegetables, he threatens to clobber them, but SpongeBob reminds Squidward that he's about to be late to work.

Later, at the Krusty Krab, Squidward asks SpongeBob to take out the trash.  Instead, however, SpongeBob and Patrick become Mermaid Pants and Barnacle Star again, and they destroy the garbage bags, sending trash flying everywhere which causes all the customers to leave in disgust.  Mr. Krabs sees all the chaos going on and pulls Squidward into his office, where he tells Squidward that the only way to get Mermaid Pants and Barnacle Star to snap out of it is to play along with their game.  Mr. Krabs dresses up as a supervillain named Captain Tightwad, and makes Squidward dress up as Dr. Negative.

Captain Tightwad and Dr. Negative challenge Mermaid Pants and Barnacle Star to a duel, but after a short while Mermaid Pants realizes that the villains haven't committed any crimes, so they have no reason to fight.  Mermaid Pants forces Captain Tightwad and Dr. Negative to "rob" a bank, so they go to the First Nautical Bank to pretend to rob it, but get beaten up by an overzealous security guard.  Mermaid Pants and Barnacle Star let it slide, though, and they move the game into the next phase.  They bring Dr. Negative and Captain Tightwad to a store to buy props for their evil lair. About an hour later, Captain and Tightwad have the Krusty Krab converted into an evil lair, with Mermaid Pants and Barnacle Star hanging over a vat of boiling oil.  Mermaid Pants says that this is the scene where the heroes and villains have a climactic battle, but Dr. Negative hijacks the game and tries to destroy Mermaid Pants and Barnacle Star for real by dropping them into the oil.  Captain Tightwad tries to talk Dr. Negative down, but Dr. Negative declares that this is his chance to get revenge on SpongeBob and Patrick for years of aggrivation.  However, Mermaid Pants and Barnacle Star manage to escape, and Captain Tightwad and Dr. Negative fall into the oil instead.

In the episode "Appointment TV", Squidward cosplays as Dr. Negative once more as part of a Mermaid Man-themed musical play SpongeBob's friends made for him.
