Boots The Tuxedo Cat

BACKSTORY:

Boots was created in a robotics factory in Vietnam. Of course, Asian countries like Vietnam don't exactly have the best pay.

Tired of how poorly management was treating him and his coworkers, one of the factory workers took broke the behavior limiter on Boots's endoskeleton's chest, then took out the shard of the broken cover for the limiter, and put on a new cover (which was given to him by one of said coworkers.) to make it seem as though everything was fine and nothing happened. (The factory lacks security cameras and higher ups weren't watching at that time.)

The rest of the workers did the same thing, keeping their big mouths shut and pretended not to notice, because they too wanted to get even with management.

The same worker also tampered with Boots's eyes, giving them the red glow, and also screwing up the processors, scanners, and the internal database they were connected to.

Another reason for Boots's aggressive behavior is that the worker who broke the limiter had also built a virus containing chip himself, which corrupted the system, basically making Boots evil.
