This is a modified and powered-up version of the Thunder Machine Tallgeese, which was damaged in the battle with the Armor Fighting God Wing. It emits static electricity throughout its body, which reduces the aircraft's air resistance to the limit and further increases its incredible speed. It combines with the similarly powered-up Flame General and Flood General to form the Heavy General Giga Tallgeese.
Lightning Knight Zechs pilots the Thunder General Tallgeese. He takes on the Armor Fighting God Wing in this new machine.
