Clyde.

Remember when Springtrap was still "new" and people thought he was green?

He flirts with Toy Chica and always 1-ups poor Bonnie. He's kind of a bully, but the fun kind that just friendly-teases with no malicious intent whatsoever. He's the "frenemy".

He'd be the type to be at the door one moment, leave immediately after it closes and wait patiently until it opens again.
...And he's actually based off of my shiny Jolteon.
