Torture Golden Lockjaw is an antagonist in TRTF 5. He first appears in FIND ME.exe in a mini game where Green Guy is collecting or catching children's bloody limbs. Green Guy will later fall on the ground crying, then he will start removing his jaw. After a few seconds, Torture Golden Lockjaw will jumpscare the player, ending the minigame.
If you look closely at Torture Golden Lockjaw's final frame in his jumpscare, you can see human eyes and flesh inside the suit. As of the release of The Return to Freddy's: The Dreadful Truth, it is confirmed that this is, in fact; Gron's flesh and eyes.
