Zombie Cheshire cat They're being haunted by a friendly spirit that loves them.
Inner shirt is sleeveless. The shirt is really long, ending at below their butt. They are wearing a pair of shorts underneath. Androgynous child. Can be drawn with their hair tied or let down. Has a slender male physique. Usually has their mouth closed to hide the extremely sharp teeth they have.
Muted emotions until triggered. Once triggered, all their emotions bursts through. Becomes slightly insane and attacks the one who triggered them with their teeth and claws.
Claws are hidden by their thick oversized outer jacket.
Usually opens their mouth so wide that their skin tears when they get triggered. They have insane regeneration so it never leaves a scar though. It is speculated that the spirit that attached itself to them is one that was helped in one way or another by Nero.
Could be that Nero ate the one who killed them and that's why it likes Nero and sticks to them.
In the beginning Nero would try to eat the spirit, however Nero doesn't have to ability to ear spirits so the spirit would be shoved into their mouth, swallowed, and then casually floats back out from inside their body.
The spirit was never angry with Nero doing that, instead it seems to enjoy the process.
While it did get a little lonely after Nero stopped trying to eat them, they got really happy when Nero started to treat them like.. a pet.
