Orphic - Five Nights at Freddy's: Security Breach

After the unfortunate events leading up to Glamrock Bonnie's demise in the Fazbear franchise's newest establishment, Freddy Fazbear's Mega Pizzaplex, the team introduced an animatronic from their golfing attraction in the mall, Montgomery Gator, to take Bonnie's place as the bassist. Once an animatronic just for show in Monty's Gator Golf, he's now a permanent face of the establishment. Rocking out to his bass guitar for the kids, he's become a favourite of many. Although his new friends seem to be the same as they've ever been with effervescent personalities and working through the days even when they aren't functioning at peak performance, Montgomery seems to stand out.
The rocking alligator can't help but become trapped in this thoughts for a majority of the day. His programming allows for him to feel rather emotional for a collection of walking, talking metal. He seems to have some sort problem, perhaps a bad memory or otherwise that only motivates him to tear his room apart in a fit of rage when no one's looking. It's created a terrible habit within him to be rebellious and go against the directive. The show must go on, as they say, but it can't without everyone's favourite bassist being present for showtime.
With his secretive self and dangerous behavior, suspected to be caused by the incident that lead to Bonnie's decommission and Monty's stardom, he's noticing it's getting worse as the days pass, that it even creates a hostility within him. Even his friends are beginning to act out, especially in ways that Monty would've never imagined.
Venture with Monty and the gang as they become fully aware of the virus in their programming while slowly being turned into hostile lackeys for the man who comes back every time. They become worse with every night passing, their shells deteriorating from the damage of his power, his whole being, but they eventually find the source of the tribulation and take their only shot at rectifying their suffering.
