Real name: Martin Fitzgerald

 Age: in the early forties

 Voice:  
as robot/hare: no real demands for this voice.
as human: have to be the exact same a Jeremy



 Personality:
even with all the pain and suffering, he has been through, Spring is still incredibly kind and helpful to everyone around him. both his biggest strength, but unfortunately also his biggest weakness. it doesn't mean Spring is naive, that part of him got torn away the moment the child killer took him on and slaughtered those children right before his eyes. and if that wasn't enough, Spring has been thrown into storage and stayed in there for years, and later used in a horror attraction (he got the nickname Springtrap there, but Spring really dislike that name) in Fazbear Fright, here he was so unfortunate losing his sanity and attacked and killed a human. Spring doesn't remember the kill, but he still knows he did something horrible.
Spring is a huge pacifist, and works as the peace-keeper in the family. however, Spring is so afraid telling his family of what he remembers from both the child murder and what little he remember from Fazbear Fright. he often hides away when he feels those memories reappears into his mind. hiding all this pain does affect him into a small depressive state, never aggressive, though.
Spring is twin brother to Jeremy Fitzgerald, and they will meet in the story. 

 
 Note: whoever chose Spring will also chose Jeremy since they are twins and thus has the same voice.
