Wodan Ymir is the pilot of the Thrudgelmir, and is aligned with the Divine Crusaders. He wears a mask and wields a Colossal Blade. His voice and mannerisms are remarkably similar to the former Aggressor and leader of the ATX team, Sanger Zonvolt.
He calls himself "The Sword of Magus".
His true identity is W15, a robot constructed from the Sanger of the Shadow-Mirror's world. When his personality was reconstructed, he was bound to Magus, the main computer of the Earth Cradle, and thus fashioned himself as "The Sword of Magus". When confronted by the real Sanger, he begins to act on his own will, rather than simply obeying the orders handed to him. He decides that in order to become Wodan Ymir, the true Sword of Magus, he must defeat Sanger, something Sanger acknowledges and accepts. Sanger eventually wins this duel, and Wodan is killed shortly after, when his Thrudgelmir is destroyed after preforming a final attack to annihilate Egret Feff and his Bergelmir army.
