Mugman

Mugman is a playable character and the deuteragonist of Cuphead. He is Cuphead's younger brother & usually the second player when playing on Multiplayer.

Appearance
Mugman seems very similiar to Cuphead, but however, he has some differences. The red colors are replaced with Pacific Blue color, his straw is shorter & not bendy. His nose is larger & his eyes are separate, and seemingly smaller. His head is also slightly thinner.

Personality
Mugman's personality is shown to be more careful and less rash compared to his older brother, Cuphead. This is shown when he begs Cuphead to not make the deal with The Devil, as that would end up costing them their souls in the introduction, and causes them to start their adventure to get soul contracts. But besides this, Mugman's personality is very similiar to Cuphead's and he is partially smart & nice.

Trivia

 * In the beginning moments of a boss battle, Mugman will extend his straw and take a drink from the liquid in his head.
 * Like Cuphead, in the final boss (or failing the Mausoleum level), Mugman will quickly hop from foot to foot, waving his arms with a scared expression.
 * According to an interview with Studio MDHR, the liquid inside Mugman's head is the essence of his soul.
 * Just like how Cuphead seems to be based on Mickey Mouse, Mugman seems to be based on Oswald the Lucky Rabbit, sharing a similar color scheme and being the brother of the protagonist.
 * Mugman and Cuphead's animations (when they use the blue potion) may be a reference to when Popeye eats spinach.
 * His name may be a reference to the video game character Mega Man, as the pronunciation of his name as well as his color scheme are similar to Mega Man's. This is even further supported by the "Run N' Gun" stages, which was the base of Mega Man.
