Gundam Exia is the mobile suit piloted by protagonist Setsuna F Seiei during the first series of Mobile Suit Gundam 00. Exia is the second Gundam to appear in the series as it overpowers and destroys the AEU's latest mobile suit, the Enact, during a public demonstration of the Enact's capabilities. Designed for melee combat, Exia's primary weapon is a massive metal blade mounted on its right forearm, which can be folded down to reveal a beam gun. Additional handheld swords, beam blades, and shield compliment Exia's armament. (wikipedia)
