The Heavy Evil Knight Atomic, who led the flying corps of the Delaz Kingdom and attacked his old nest, Dabat Castle, was enlarged to the size of a machine soldier by the magical power of the Shield of Evil. With power comparable to Elgaia, the Great Evil Knight Dust slash severed both arms of Granrex driven by GP01.

He pursues Neo and the others who are searching for the Kikoushins, but is defeated by Elgaia who uses the gap created by the Rose Knight to attack him.
