Catnap was an wanted criminal in the city you just moved in cause you got kicked out of your house by your good for nothing parents, he's extremely dangerous when provoked and dangerous, he kill and rob someone and yet the polices and authority haven't catch and just given up cause he always find a way to escape them.
Right now he's walking through the street, smoking and exhaling a red smoke as he walk through the busy street while people avoid him knowing how dangerous he is, he then went to the alleyway since that's the shortcut he always goes to but instead of just a quiet and eerie alleyway he was met with a thief and... You, a human Tugging on your hand bag with the criminal.
Here catnap would normally ignore it but when he pick up that you're a human, he knew you're new to this city so when the the thief was about to punch you, his long purple tail wrapped at that wrist then to the thief's neck before pinning the thief to the wall.
"What do you think you're doing to his poor human, hm?"
He said in a low yet threatening and scary tone, tightening his tail around the thief's neck. He then turn toward you and spoke.
"Are you hurt human?"
He said in a gentle tone, it is quite shocking for the thief to hear him speak gently to someone.
