Mugman can also summon an ally that resembles his ghost form albeit more muscular with one of his Super Arts. His ghost form when his health hits zero makes him legless with his legs replaced by a ghostly tail. His body also separates at the waist upon taking damage but pulls itself together within half a second. His eyes are smaller and his head is slightly thinner compared to his brother. What's different about Mugman's appearance compared to his brother is having a blue color scheme to replace Cuphead's red, a shorter straw (which elongates to a longer length in one of his intro animations breaks 20% of the way up from the bottom when something hurts him only to pull itself back together), and a much bigger nose.
Mugman is very similar in overall appearance to his twin older brother Cuphead, with his head reminiscing a mug and his body being almost identical to his sibling: wearing a black, long-sleeve shirt, yellow gloves, a pair of shorts and brown shoes, although artworks sometimes show him with white gloves.
