Mysterion is the super hero identity of Kenny McCormick. He is one of Mr. Garrison's fourth grade students at South Park Elementary masquerading as a vigilante under the pseudonym 'Mysterion'. He unveiled himself after the Coon persuaded them to for the good of the town. His defining features are his poverty, his willingness to help others in a time of need, as well as his inability to convince his friends of his inability to stay dead, which he views as a curse.
