A member of the Darkness Army's Mobile Artillery Corps, he boasts great firepower. Not only does he surpass Gaza-C in firepower but his mobility as well, allowing him to fire artillery without transforming. In order to defeat Shodai Gundam Daishogun and his companions, he headed for River of Rhino with Gaza-C and Galluss-J, but Sai Gundam sensed his comrades' murderous intent and took the initiative.
