Fredbear is a boss in Slender Fortress.
Fredbear looks identical to Nightmare Fredbear, the only difference is that he is not damaged, or has sharp teeth and claws. It is the same appearance as Nightmare Fredbear except without the red tints on his teeth, not damaged, and no claws. There is also a darker version of Fredbear called Nightmare but instead, he is not damaged. Fredbear also has his microphone just like Freddy Fazbear. It also may look like that Fredbear still has the endoskeleton teeth behind his normal teeth. He also has a purple bowtie and hat that looks the same as Nightmare Fredbears hat and bowtie. He also has 2 black buttons on his chest just like Nightmare Fredbear. Fredbear may look like the Unwithered animatronics, but instead he would be called a Unnightmare, however this is what he could look like back in Fredbear's Family Diner. Now although you can see Fredbear in the FNaF 4 minigames, you can't find him in the non minigames, you can find Nightmare Fredbear but not Fredbear.
