Red the Rabbit

Red the Bunny is a red rabbit animatronic, and first appeared as one of the secondary antagonists of FNAF 3 (Caleb40043's version). He is shown to be one of the smartest, only behind Modern Freddy in terms of AI. He was formerly a child named Mark, age 12, before he was cornered by the killer (AKA the Purple Man), and eventually shoved into a spare red Bonnie suit resembling Toy Bonnie, Red was eventually placed in use, all while his corpse rots. As a result, he haunted the animatronic, willing for revenge. He acts as a rival to them in normal purposes, but as he got to know them during the night, his programming instead had him being a rival for fun, rather than thinking his tunes were always better.

FNAF 3 Information
Starting location: Red's Lair

Becomes active on: Night 2

AI: When you focus the camera on a certain spot, he might bypass that area, he'll do this more often on later nights. He also adapts to the player's strategy, similar to Modern Freddy, though he usually undergoes a normal strategy until Night 3. If you keep closing both doors for an extended period of time, he will teleport in the office and jumpscare you.

Trivia

 * He can be seen crying oil, this is due to him remembering his times as a child before being stuffed into a suit by the killer.
 * He is often the 2nd most aggressive, behind Modern Freddy.
