Ultimate Gran Cross (アルティメットグランクロス) is the deathblow of Shinkalion E5 MkII X ALFA-X.
Description[]
This version is unchanged from the X Gran Cross of the ALFA-X X Mode, aside from being tinted green from the power of the E5 MkII. The resulting beam is extremely similar to the Over Gran Cross, though the beams are headed by spiraling discs that cross in an x-shape.
