Anime
In the anime, Kid Grave is a robot created by Lord Wily to believe he is the leader of Grave (Gospel) while being manipulated by the real leader and disguising his identity, similar to Sean in the games. When Wily no longer needed him, he revealed the truth to Kid Grave and disabled him, leaving a empty shell. After the defeat of the bug beast Gospel, Bass.EXE jacked in the robot, and used Kid Grave's body ever since to move in the real world.
