The only thing that I can say about how I came up with this guy is how cats both big and small silently creep up on their prey before they pounce which is very much a part of his bio above. I just decided to take the meaning of creepy much further and made him an absolute weirdo who no one except his partner likes to have near them, but they keep him and his buddy around due to pity since although they are a criminal gang, they aren't totally heartless.
