Bonnie

Bonnie is a primary antagonist of Five Nights at Freddy's, Five Nights at Freddy's 2, Five Nights at Freddy's 3, and Five Nights at Freddy's 4.

Information
Bonnie is a purple animatronic rabbit and member of the Freddy Fazbear's Pizza band, along with Freddy Fazbear and Chica. Haunted by the carcass of a murdered child, Bonnie is the original game's most active and prominent enemy, and usually the first one who begins hunting down the player, the night watchman Mike Schmidt. He resumes a similar but slightly less prominent role in FNAF2 as Toy Bonnie and again the most prominent and dangerous enemy as Withered Bonnie, and in FNAF4, he haunts the child's house as Nightmare Bonnie. His oldest model, Spring-Bonnie, eventually turned into Springtrap.
