Gebelk discovered that he could quickly increase the strength of such ka by forcing the wielders to struggle for survival. As such he had ten criminals, including Five-Eyed Horned Ogre's host engage in a battle, where only one wielder could leave the arena alive. After 34 hours of on and off battling, Five-Eyed Horned Ogre and Gudoul were the only surviving ka and had significantly grown in strength.
The battle was interrupted, when Gebelk and Akhenaden hoped to test Kisara and her ka, The White Dragon. When Kisara was put in the arena, the prisoners focused their ka on her. Seto intervened and had his ka, Duos, cut the arena's suspension chains, causing Five-Eyed Horned Ogre and its host to fall to their deaths.
