Foxy makes an appearance in Five Nights at Freddy's 2, in a more tattered state, like the rest of the old animatronics in the second game.
Foxy's suit has become even more tattered and the fur on his left ear has come off completely. The teeth of his endoskeleton are now highly visible, this being true with every old animatronic. Notably, the design of the original rips have changed or enlarged slightly and resemble the type of rips seen on Freddy Fazbear's redesign, showing off the upper portion of the endoskeleton's arms. The sides of his face and his chin are now much more pointed. The fur on his lower torso is almost completely missing, revealing his endoskeleton. Like Chica, he has three toes in this game, instead of two.
Oddly, both teaser pictures show Foxy with the standard LED "eyes", while his appearance in the trailer displays him as if he still has his yellow eyes from the first game. Foxy also lacks eyebrows, like every other old animatronic, excluding Freddy and Golden Freddy. His black dots on his snout have been removed as well. His hook is dangerously sharp, and it seemingly can bend and swivel.
Parts/Service is the only room in which Foxy will be able to be seen on camera. If all of the other animatronics have already left, he can appear standing in the middle of the room. He will also come directly back here when the player manages to repel him. Foxy will then make his way back to the hallway outside of The Office.
Foxy's behavior is quite different when compared to the first game. He starts at the Parts/Service area before making his way to the hallway outside The Office and will try to pounce the player from there. Foxy, along with The Puppet, completely ignores the Freddy Fazbear Head; the only way to prevent Foxy from attacking is to strobe the Flashlight down the hall at him once while he is there.
According to Phone Guy, this causes him to either be "reset" or stunned, and he will eventually return to the Parts/Service room to continue the cycle. If BB enters the room, the player's lights will be disabled, revoking the ability to counter Foxy. Unless the player is close enough to 6 AM, Foxy will most definitely cause a Game Over this way.
