Withered Bonnie is the secondary protagonist of Five Nights at Freddy's: The Twisted Ones. He is an alternative counterpart of Withered Bonnie from Five Nights at Freddy's 2 and the former guitarist of Freddy Fazbear's Pizza.
The gigantic rabbit’s blue fur was stained and matted, and his long ears drooped forward, almost obscuring his wide, square face. He still held a red bass guitar in one enormous hand, though it was battered and broken.
Half of his bright red bow tie had torn off, giving his face a lopsided look.
Like the rest of his fellow animatronics, Bonnie is first seen deactivated in Clay Burke's boiler room. John, Jessica, and Clay Burke arrive at Clay's home to ask the animatronics help to save Charlotte from the clutches of William Afton and his twisted abominations. However, Bonnie and others don't respond at first, that is until John mentions "William Afton." At the sight of hearing that name, the original animatronics (excluding Golden Freddy) go berserk and immediately take off to search for their long-awaited nemesis. Later on, when the heroes are cornered by Twisted Freddy, Twisted Bonnie, and Twisted Wolf in Afton's hideout, Bonnie manages to arrive in time. He and Chica then fight against Twisted Bonnie, working together to dismantle the imposter and turn him into scrap metal for good. However, he and the others strangely disappear when Afton's hideout collapses.
