These are villains which are from Five Nights at Freddy's, more specifically in this case, have appeared in spinoffs and fangames of FNAF, or related/fanmade media of the franchise. Examples of this include POPGOES, JOLLY, and the FNaF VHS tapes by Squimpus McGrimpus. Many of them are animatronics, although there can be exceptions like the Five Nights at Wario's and Five Nights at Treasure Island cast.
