Megadalton John, also known as Dalton, is an unstereotypically burly Mystic. He lives in Tin Can Central and is close with Geronimo Toskale. He speaks quickly, frequently reusing words and pronunciations in rapid succession.
Megadalton John also likes to drink alcohol and use Frost. This is one of the primary reasons why his courtship on and off over the years with fellow mystic Imogene never bore fruit.
He has been on Calydon for many years, and is one of the members of the secretive Frumentarii. Notably the animal denizens of Calydon seem to have some affinity with him, due to his Animal Empathy.
One might imagine him to be like Neil deGrasse Tyson.
