Molten Freddy first appeared in Freddy Fazbear's Pizzeria Simulator in 2017 as a melted, tangled version of Funtime Freddy formed from remnant and wires. Actor Kellen Goff voiced the character in Ultimate Custom Night in 2018, where his animatronic attacks came with short taunting lines. Fans clipped those lines for soundboards and edits, separating each taunt so creators could trigger the exact scare they needed. The clips remain popular with FNAF fans making fan games, animations and horror edits online.
