Mega

Mega Man (ロックマン Rokkuman) is a character in the Plotagon parody universe. He's based on the titular character from the Capcom franchise Mega Man. He was initially created by Dr. Light to be the household robot Mega, although he is then transformed into a slightly more powerful fighting robot at the end of Mega Man: Plotagon'd Up.

His first appearance in Harry Pothead Chronicles was in S1E3. He is accused of attempting to murder Dr. Wily, but the charges are dropped when Tim Cook, the case's prosecutor, assaults the Judge.

As Mega
He is earnest and wants to help his friends, just like the actual Mega he is based on. Very little was changed about his personality, other than his initial quotes, which imply that he is naïve.

As Mega Man
Despite being slightly more powerful, a glitch makes him repeat words, and it is unknown if he is actually able to fight. Dr. Light might have fixed his glitch, but as a consequence he seems to be oblivious to reasoning.

Sometime between the creation of Mega Man: Plotagon'd Up and S1E3, someone disguised as Mega Man attempted to murder Dr. Wily, leading to his trial. Mega has nothing to say about this besides "oh crap that's right".

Trivia

 * He is the only character in Harry Pothead Chronicles to also have a Japanese name.
 * There is no Japanese localization of Harry Pothead Chronicles. However, it is referenced in the American dub.
 * Neither Dr. Light or Phoenix Wright have their original Japanese names referenced in Harry Pothead Chronicles.
 * Mega Man's hair is supposed to resemble the helmet from his classic games.
 * He states he's from Mega Man 2 specifically, despite his debut parodying Mega Man: Powered Up!. It is likely that a certain amount of time has passed since his debut.
 * His profile artwork shows him doing air guitar. This is a reference to his Japanese name, Rockman, and the fact that the music from the franchise is predominantly Rock n' Roll-inspired.
