Merloo

Merloo is a member of the Tribe of Ancients who is indirectly seen in the form of a stained glass window in Mirror Hall of Super Paper Mario. According to Tippi, Merloo was very wise in his time and is even thought to be the author of the Light Prognosticus. Interestingly, unlike all other sages among the Ancients, Merloo possesses no current inhabitant of Flipside or Flopside who bears any direct resemblance to him, although some other Shamans of past Paper Mario games (perhaps especially the Merlee of Paper Mario: The Thousand-Year Door) do look slightly similar to Merloo, who takes on the appearance of a mustache-less, green-robed character slightly resembling Merlon. It is also very interesting to note that Merloo is said to be a powerful, dimension-controlling magician; he therefore shares many skill-related characteristics with the villain Dimentio, making him a possible relative candidate. (Merloo being related to Dimentio may further be implied by the fact that one of Carson's stories vaguely suggests that Dimentio may have written wrote the Dark Prognosticus, much how Merloo wrote the Light one to counter it.) However, this is unconfirmed.

He bears very minor resemblance to Toad, though this may be coincidental.
