Dr. Light

Doctor Thomas Light is a character from Mega Man. He makes his first appearance in Mega Man: Plotagon'd Up. He created Mega and Roll, two household robots, as well as 8 industrial robots. However, his rival, Dr. Wily, steals his 8 other robots. When this happens, Mega asks to be transformed into a fighting robot. He is initially opposed to the idea, but sees it as an opportunity, and turns Mega into the super fighting robot Mega Man.

Personality
It is very difficult to read Dr. Light. He seems to love pranks just as much as Ruby Haggerd, although these usually involve personal insults rather than dark humor. One of Light's favorite pastimes is to exclaim "H M M M M", in an attempt to show that he is thinking. This rubs off on Mega Man, who also does the same thing.

Trivia

 * Dr. Light's name may come from the fact that he isn't very bright.
 * The only character who calls him by his full name is Tim Cook.
