You mean a character that just stares at people?
That's not really a character, is it?

Actually, it is. The lore has a bit of story on Springtrap and his ties to the Purple Man. Lore that will get into heavy spoilers.

Basically, Springtrap is the animatronic that is empty. When the Purple Man was running from the ghosts of the children he killed, he hid in the suit, only to be crushed to death in it. In short, Springtrap is Purple Man's own personal animatronic.
