Bonnie is the original purple rabbit animatronic from Five Nights at Freddy’s, guitarist for Freddy Fazbear’s Pizza and one of the first performers to demonstrate that the night shift has gone extremely wrong.
During business hours, Bonnie belongs to the restaurant’s main entertainment lineup alongside Freddy Fazbear and Chica. After hours, he leaves the stage and moves through the building toward the security office, typically threatening the guard from the left side.
His classic design is simple enough to become instantly recognizable: purple rabbit body, long ears, red bow tie, and guitar.
That original identity matters because the FNaF series eventually becomes crowded with other rabbit animatronics. Toy Bonnie is a separate newer-generation performer. Spring Bonnie carries an entirely different history. Later damaged or alternate designs may resemble Bonnie without automatically replacing the original character.
Standard Bonnie remains the guitarist who helped establish the franchise’s basic nightmare:
These things move when you are not looking.
Even later appearances continue to play with that relationship between Bonnie and the cameras. In Ultimate Custom Night, simply watching Bonnie at the wrong moment can temporarily disable the entire camera system.
Apparently the guitarist has opinions about surveillance.
