Fredbear.

Golden Freddy is a golden-yellow variant of Freddy, using the exact same model, albeit with different coloring and eyes, as well as being in a slouched sitting position. Golden Freddy has a black top hat with matching bowtie, with two buttons down his chest and a microphone in his right hand.
 * Golden Freddy is the only character in FNaF World who does not move in his idle animation, instead simply sitting still while his pupils flash.
 * This is a direct reference to Golden Freddy being completely slumped with seemingly no movement from the first three Five Nights at Freddy's games.
 * However, when he is attacking, his head shakes.
 * The "it's me" on Golden Freddy's loading screen is a reference to Mike Schmidt's hallucinations in Five Nights at Freddy's and post-night cutscenes in Five Nights At Freddy's 2.
 * The Ghost Freddy summoned by the Haunting Attack may be a reference to the Missing Children Incident, a huge event in the Five Nights at Freddy's series.
 * On the "Thank You!" teaser, there was a giant floating Withered Golden Freddy head, which appeared inFive Nights at Freddy's 2, was removed for various and unknown reasons.
 * Interestingly, in endoplush's loading screen, it is stated that there was a character quota and Endoplush took up the last spot rather than Withered Golden Freddy. It is unknown why that is.
 * The character quota mentioned on Endoplush's loading screen could be a joke, rather than there being an actual quota.
 * In the original Five Nights at Freddy's series, Golden Freddy was speculated to be Fredbear. However, Golden Freddy does not cause the universe end.
 * However, this could be because Golden Freddy is technically his own separate entity, while the two Fredbears are exactly the same.
 * The fact that Golden Freddy and Fredbear being in the same place don't cause the Universe End could also be because Golden Freddy is Fredbear from another time. This is supported by the fact that mangle and funtime foxy don't cause the Universe End, despite being the same animatronic.
 * This could also apply to springtrap and spring bonnie.
