M.X.E.S is a sentient security program designed to keep the Mimic hidden in the decrepit Freddy Fazbear's Mega Pizzaplex now in ruin.
It looks like a glitchy, noncorporeal rabbit animatronic with five long fingers. It lacks legs and instead has a levitating, cylindrical "tail". It has no arms, with its shoulders, elbow joints and hands being connected by a white, wire-like string. M.X.E.S is dark blue in color with white circuit-like markings and purple glitches all over its body.
