Muchana is a doctor who currently works in Impel Down’s medical room.


Muchana is a man with black hair who wears an Impel Down uniform that consists of a white suit, garnet gloves, a shirt with the Impel Down symbol on the lapels, and a black tie. Being part of the medical team, he wears a doctor’s mask that covers part of his face, and a white cap with a small Impel Down symbol on one side.


Little is known about Muchana’s personality. He is nervous when talking to Hannyabal, possibly for fear of receiving retaliation from a superior.

Abilities and Powers

Muchana possesses some medical experience and seems to know the poisons that the Doku Doku no Mi produces very well.

Impel Down Arc

In the medical room of Impel Down, Bentham (disguised as Hannyabal) asked him about Luffy’s condition after Magellan’s attack. He told him it was impossible to create an antidote to counteract multiple poisons from Magellan at once, and there was no way to save him.


  • His name is likely a pun on “mucha na” (無茶な?, meaning “unreasonable”), referring to the request to cure Luffy’s poisoning.
  • Stephen Paul, the official VIZ translator, informally translated Muchana’s name as “Notta Magician”. This translation was later used in the 7th popularity poll.
