Geo Stelar[edit]
Geo Stelar is the main character of the series. Though being smart, since his father has disappeared along with others on space station he has been skipping school. He doesn't go to school because he is afraid of making friends and losing them like his father. After he merges with the AM-ian, Omega-Xis, he can become Mega Man. He lives with his mother, Hope Stelar, and loves space.
Luna Platz[edit]
Luna is the perky and bossy fifth-grade class president of Echo Ridge Elementary. In the beginning of the game, she constantly tries to get Geo to come to school, claiming that it's her job to get him there. When Geo finally comes to school, Luna basically treats Geo like another flunky, but slowly opens up to him, especially after she learns who he is.
Sonia Strumm[edit]
Sonia is the heroine of the series. She is a popular rock star who, like Geo, is depressed over the loss of a parent (in her case, her mother) which leads them to establish a friendship. Although cheerful and easy-going, Sonia is constantly pressured by her money-starved manager, leading Lyra to manipulate her into transforming into Harp Note, and attacking people throughout the city with guitar wails. Following her defeat by Mega Man, Lyra becomes an ally of Omega-Xis. In the game, Sonia Strumm decides to dump her manager and retire for the time being and return to normal life.
Bud Bison[edit]
Bud is a gruff bully, who attempts to intimidate Geo into returning to school. During one such encounter Omega-Xis's brash personality causes Geo to punch Bud, leaving him embarrassed and his companions questioning their association with him. Taurus acts on his anguish, offering him the power to get Geo back. Escaping into the cyber network of a truck that Luna and Zack are riding in, he drives it recklessly through the city, attempting to run Geo over.
Zack Temple[edit]
Zack is a somewhat nerdy and condescending student who is more or less one of Luna's flunkies. Zack seems to also have a problem with his height and tries numerous ways to get taller. Zack also appears to be afraid of heights. After discovering Geo was Mega Man, Zack starts to admire him more.
