To say that Officer Keys is enthusiastic is an understatement. Keys takes pride in his job and lets everyone know it. He has an overly friendly demeanor and always seems to be in a happy mood. This usually contrasts with the things he carries out throughout the city that might disappoint those. The reason for this might be due to the fact that he simply enjoys fulfilling his role in law enforcement. Nevertheless, he is not intentionally malicious and is merely doing his job as he sees fit.
In "Green Streets", it is revealed that he chooses to retain a sunny disposition as opposed to a serious hard-boiled attitude because he finds it difficult to maintain such a persona. It is further implied that it is because he does not want to unintentionally scare or harm people while he is on duty.
The episode "Greens' Acres" reveals that he has been like this his entire life. His reasoning for deciding to be a cop was actually due to his own social ineptitude. When a young Russell Remington stopped Bill Green and Nancy from fleeing from the law, the arcade owner suggested that he become a cop, only for Keys (who was standing next to them) suddenly announce his intention to be one instead, much to the arcade owner's confusion.
Officer Keys is tall and has light magenta skin and purple hair that is shaved down short. He is always in a blue police uniform and seems perfectly fit. He also has a thick black chevron mustache that covers his mouth when it is closed.
- Keys seems to be the only officer available in Big City.
- Andromeda is under the belief that Keys is an alien. This would be understandable as there is something unsettling about his happy demeanor.
- Keys is taking night classes so that he can be a judge.
- In "Heat Beaters", it is implied that he is not well liked by the rest of the Big City police department, possibly because of his personality.
