This mysterious mobile suit is created by OZ leader Treize Khushrenada, based on data from the Tallgeese and the other Gundams. In keeping with Treize's philosophy, the Gundam Epyon eschews cowardly long-range weapons in favor of chivalrous close combat. Its main weapons are a segmented, whip-like heat rod, and a powerful beam sword whose energy is supplied by a direct connection to the Epyon's generator. The Epyon can also transform into a "mobile armor" mode for high-speed flight.
