Lucius

Lucius is a mouse animatronic and the leader of the band from Lucius & Others.

Appearance
Lucius is a white mouse animatronic with a jaw, round ears, blue eyes, buck teeth and a bowler hat. He has five fingers on each hand and three toes on each foot.

Behaviour (Ultimate Pizzeria Mode)
Lucius appears in the left closet, he won't do anything until the power goes out, he'll make everything pitch black and eventually kill you.

Behaviour (Ultimate Pizzeria Mode Deluxe)
Lucius acts similar to Ultimate Pizzeria Mode but also he has the most basic mechanic. He can appear from any hall, when he moves closer to the door, you will hear footsteps. When you hear loud footsteps and see Lucius' face flashing at any door, close that door or he will play his song in your office, agitating sound sensitive animatronics and eventually he will jumpscare and kill you.
