All that is known is that Mysterion is a student in Mr. Garrison's fourth grade class and Cartman correctly guessed who he was earlier in the episode.
From Wikipedia

Also it's not Kyle or Butters because they were shown with Mysterion in the episode..........it's probably some minor character noone cares about. Oh well wait til the next episode maybe more will be revealed
