Watabore

Origin
Watabore is a tremendous “scientific giant” who, instead of eating humans or animals, eats information. He falls ill after devouring too many indiscriminate opinions and cannot be cured until he alters his diet to only eating opinions he deems worthy after careful consideration. Among the characters to offer him questionable medical advice is the Man in the Moon.
