Come down the rabbit hole

Okay Chessur has some weirdly special abilities.

He can turn into vapor and seep into anything that has a crack thus getting into almost anything.

He also has limited shape-shifting abilities. (Which I am going to head-canon here since there is no definite answer.) He can change into any form as long as he one of the personal belongings of whoever it is he is turning into. Remove it and he will shift back. His eyes always look the same no matter what form as well.

With that said just fill out this handy dandy form:

<b>Can Chess randomly appear wherever you live?</b> <b>Can Chess randomly appear near/on/close to you?</b> <b>Is there anything he is not allowed to do/take/whatever?</b> <b>Is he allowed to shape-shift into your character at some point in time?</b> <b>Anything else you'd rather he not do?</b>
