Okay, i'm going to be honest i've never played Five Nights At Freddy's 3 or the two previous games,
it's not because it has jump scares or anything it's just that looking at cameras none stop isn't really my cup of tea.
But i've watched videos of the games and i've done my research so I know about the story and stuff.
Anyway, it's Springtrap the animatronic that the Purple Guy died in and now possesses to carry one his bloodshed in Fazbear's Fright:
The Horror Attraction.
This guy quickly became my favorite with his decayed body and his creepy smile, which I find absolutely adorable
Also I find him to be the saddest out of all the animatronics, cause he's been possessed by a child serial killer. So I feel really sorry for him(the animatronic itself not PG)
