My idea for Nightmarionne is that they will have no static, and will creep up behind you when your not paying attenion.

Their haywires is normal.

You would have a half second to shock them.

They have a chance to spawn in a FNAF 4 remnant collection when you collect to much shadow remnant, and they would have their tenticals try to grab you from under the bed, from the closet, and from the doorways, kinda like FNAF Help Wanted.
