Recurser appears as two characters in one, basically a 4D being.
The one on the outside is completely white, blocky, and slightly obscured by a portal-like frame. Their hands are designed to look like microphones. It has a singular rectangular eye, and aspects of the menu, as well as its own spritesheet, on its body.
The being on the inside has the same eye, both of them have a red bar covering their eye, acts friendly so that they can lure Tristan back to Dave.
