During the fight, a vision of Mag Mel and Razenoid appears, and Grey and Leo think they are fighting them instead of Anubias, causing them to lay waste to the field and endanger the crowd. To make matters worse, Zenthon reappears. Once Zenthon leaves, Grey and Leo's vision are returned to normal.

Later, they meet up with Preyas and Amazon at one of Leo and Drago's training grounds.

So, they battle Amazon but lose control during the battle and are defeated. They later faint from exhaustion while Preyas and Amazon leave. Dan and Drago are seen later talking about what happened and Dan and Grey admits that he has no idea what to do.
