Gundam Epyon

OZ-13MS Gundam Epyon was amobile suit created by Treize Khushrenada during the time he was placed under confinement by the Romefeller Foundation. The Gundam Epyon, eschews cowardly long-range weapons in favor of chivalrous close combat. However, when the suit becomes a part of White Fang, a pair of vulcan guns are added to the head. Its main weapons are a segmented, whip-like heat rod mounted on a shield, and a powerful beam sword whose energy is supplied by a direct connection to the Epyon's generator. It was also installed a modified version of the Zero System known as Epyon System in the cockpit, making this suit a powerful opponent. The Epyon can also transform into a "mobile armor" mode (referred to as 'dragon-mode') for high-speed flight and cruising in space. The unit resembles a mythological dragon in this mode, however its primary weapons are inaccessible save for the Epyon Claws which are used as landing gear in this form.. (from Gundam Wiki)
