Gatry in game:
Gatry would be a neutral animatronic. Only chasing if provoked(Shot with Fazerblaster or hit with the Fazcam). He takes a liking to outcast kids he "finds". The kids actually find him if they're upset. Gatry calls the outcast kids his gator pups, and the kids like that because Gatry is also an outcast from the others, and he understands their issues, and are fine being called "Gator pups" since something like that would never exist. Gatry makes them feel better about themselves. At late at night Gatry would be in the daycare with Sun/Moon and try to keep them company. Trouble makers are also familiar with Gatry, since Gatry works as a Security Bot like the other ones, but it takes a lot to anger him. Once Gatry is angered by a kid, he will tell them off, or ban them from specific rides for a specific amount of time. Parents understand. Gatry has never had an accident, even when a kid or an older person(like a Karen) has pushed him over the edge. when Gatry is pushed over the edge, he will force them to leave. Gatry wants what is best for the other families and robots. Gatry is close to Monty, Buni and Roxane.
Info from the mystery bags(if in game):
Gatry was a scrapped concept for Montgomery gator, Fazbear Staff didn't like the way he turned out after he was built, so he was to be used for spare parts. But the staff member who mentioned Buni however, took a liking to Gatry. The staff member didn't discuss why, but had a seem of liking to odder animatronics, and preventing Gatry from being used for parts. instead, the Faz staff member changed how he looked, and made him into what he looks.. now? I don't know how to to describe it, but that's how Gatry is now.
In-game dialogue(after finding bag and if it was in game):
Gregory: "Gatry"? ..First Buni, now Gatry. This is getting weirder and weirder.
Glamrock Freddy(Through Fazwatch): Well, it was an older modal of Monty, so I guess it makes sense.
Gregory: I guess so. Have you ever met him?
Glamrock Freddy(Through Fazwatch): no, I haven't. I've checked my memory files, nothing was there from what I've seen of him.
Gregory: then how do you know him?
Glamrock Freddy(Through Fazwatch): I've heard his name being tossed around a few times from when.. I still had the others.. so that's how I know.
Gregory: huh. is he dangerous?
Glamrock Freddy(Through Fazwatch): I wouldn't think so. I would think he would be a nice band member to have on stage.
Gregory: ..alright Freddy.
