GenAIMimic
Glitchtrap is a copy of the data of the Mimic scanned in from the data diver to speed up development. Exactly like generative AI. It takes stuff mixes it all together and spits out something “new”. So to make HW they fed the mimic fnaf 1-4 and it spat out a collection of minigames. It mimics the persona of william afton, mixing spring bonney with mascot suits that it was made to be inside. Glitchtrap is genuinely dead, it only existed as a short-term villain meant to bridge the gap between WA and the Mimic.
They then saw how well that worked. So they used it again when making the pizzaplex. It got fed Fnaf 1-4 and HW, asked it to create a pizzaplex based on the franchise. Which is why there are random rooms from HW in the pizzaplex. This is also the reason why Roxy and Monty exist. The AI was asked to make 2 more animatronics, so it took characters from MCM mixed it with the animatronics and spat out Monty and Roxy.
