1: Sans Slippers (Undertale): people drew fanart for years depicting Sans's slippers as pink, but they never appeared like that in game, only in white, Toby eventually made it canon, and he's had them ever since

2: Springtrap's axe (fnaf): the fire axe is possibly the weapon most associated with William throughout the franchise, as far back as Fnaf 3, but, he never used one, in any official FnaF media, the first time he ever used one officially was as the Animatronic in Dead By Daylight
