Omersinso is the patriarchal Cartún in the major pantheon of Sinsonismo. He is the most storied character in the pantheon, with a somewhat mercurial character. He is a character of mirth, prosperity, and luck. He is depicted as a rotund adult male with a beard and bald head. He has a somewhat adversarial relationship with Varsinso, and in many Episos strangles the boy. Still, both are benevolent cartunes and their relationship is understood to be familial.
