Bonnie

Bonnie is a boss in Slender Fortress.

Description
Bonnie is a purple male animatronic bunny of Freddy Fazbear's Pizza, a family-friendly pizzeria with the entertainment being a show-band composed of three animatronics; Bonnie, Chica, and the lead singer, Freddy Fazbear. While they love children and act fine during the day, they're locked in a free-roaming mode at night where they view every human as a naked endoskeleton in need of a costume. As such, they forcefully shove said human into the suits, violently mangling them to death. However, it is implied they are in fact haunted by dead children murdered in the restaurant and the aforementioned "endoskeleton bug" is just a coverup.

In Slender Fortress
Bonnie always spawns with Freddy, Chica, Foxy, and Golden Freddy and is a standard chaser with average speed. He is hardly persistent and is fairly easy to evade, but mostly spawns out of no where, (especially around corners) and usually sandwiches the players between himself and Chica. His average speed can be rendered even slower when the player looks at him, and is a one-hit-killer, killing the player in a unique jumpscare gif.

In Medic's Slender Fortress server
Bonnie, as stated above, always spawns with Freddy, Chica and Foxy with the exception of Golden Freddy. Bonnie is a very slow chaser and can be easily outrunned by simply walking and not sprinting, making him and Chica the easiest bosses in the FNAF gang. After The Second Server update Bonnie and Foxy originally had a solo round where he is alone, not with the gang, and has no intro. After The Third Server update Bonnie and Foxy's solo round is removed.

Bonnie's speed is highly increased if the active map is currently a Broken Map, and to the point where he is a actual chaser, not a very slow chaser. If Bonnie is in alert mode or wander mode, Bonnie's walk speed is sometimes increased like how SCP-049 does.

Trivia

 * In MarioPlayz Gamez' vision, he sees Bonnie and Chica's model different, he sees their models as a T-Posed Hentai Woody with his head faced the same way he sees Grunt's models.
