Sean Obihiro

Sean Obihiro, known as Shun Obihiro in Japan, is an orphan who is Gospel's leader. It is revealed in MegaMan Battle Network 2 after you defeat Gospel, the final boss, that he created Gospel after his family died in a plane crash and he became an orphan ostracized by society. When he explains to Lan about his family, you see him holding a photobook, after he lost his Kid Grave body. In MMBN3, Sean was visiting Mr. Hikari inside the Beach Hospital, telling his story to him. In this conversation, Sean reveals that someone else is actually manipulating him in carrying out Gospel's plans.

In the Anime
Similar to Pat Sprigs, one side of Sean is completely absent from the anime. Instead, Kid Grave is the leader of Gospel, but is really a robot manipulated by Wily, similar to Sean. When Kid Grave was disabled because Wily no longer needed him, Bass.EXE jacked in, and became the new "Kid Grave". Bass has been using the Kid Grave body ever since.
