Protoman is one of the main characters in the Mega Man series. He was the first robot master created by Dr. Light.
As well known as Protoman is, he has surprisingly only made one contest. In the Summer 2004 Contest, Protoman debuted as a 13 seed and his score was almost tripled by Zero. Some still wonder how Protoman would do today if he were to make another contest.
On another note, Protoman is the 100th character to appear in any character battle.
