ガンダムエピオン
[b]OZ-13MS Gundam Epyon[/b]
A Gundam-type [[Mobile Suit]] developed by [[Treize Khushrenada]] based on the [[Tallgeese]] and 5 Operation Meteor Gundams. True to Treize's philosophy of combat, it was only armed with melee weapons: a heat rod and a very high-output, large [[beam saber]] that is capable of destroying space fortresses. It also possessed the ability to transform into a flight mode (with a twin-headed dragon design), and was equipped with the fearsome [I]Epyon System[/I], a modified version of the ZERO System that enabled its pilot to control the battlefield. 

While it was originally [[Heero Yuy]] that relieved Treize of the Epyon, he later exchanges the unit for the [[Wing Gundam Zero]] with [[Zechs Merquise]] after a brief scuffle.
