Charon appeared in Saving the World From Ruins! but did not speak. He was briefly seen at Team Galactics base. In Gateway to Ruin!, he made his first full appearance alongside Saturn as they searched for the Spear Pillar in Mt. Coronet. Later, Charon assisted in the final stages of the Red Chain project during the finale from Unlocking the Red Chain of Events! to The Battle Finale of Legend! Unlike the other Commanders, he was not arrested at the end of the arc and presumably escaped. Compared to other Galactic members, Charon is more relaxed and upbeat, which often leads to one-sided disagreements with Saturn. He uses a laptop computer for much of his technical work on Team Galactics' plans, including monitoring energy levels and statistics.
