Zepon was the Chief of the Lizard Clan who was assassinated at the outset of the War of the Champions as part of the Destroyers plot to incite war between the Zexen Federation and the Six Clans. He had crossed paths with Yuber in the past and Yuber would take pleasure in assassinating him.
In the original invasion of the Grassland by the Holy Kingdom of Harmonia, 50 years prior to the War of the Champions, Zepon had fought alongside the Fire Bringer and its leader, the Flame Champion. As such, he was also an old friend and comrade of Geddoe, who had visited him before his death.
