Trivia[ | ]

  • It is the boss version of the MawMaws.
  • The Gate is the posthumous version of it.
  • Before its fire attack, a purple flame can be seen emanating from its forehead.
  • Despite its name, it acts and looks more like a HorfHorf (or a Psychic HorfPsychic Horf) than a Maw, because it does not move and its eyes are more round.
  • Its fire attack could be a reference to Mega Man's leaf shield/attack.
  • (in Repentance) The visual appearance of the Red Champion version may be a reference to the (in Repentance)Collectible 2Spooky icon2Spooky item.
