While Gamu Takayama was on a plane to visit his family, he saw Bokurag's huge shadow underneath the water and called XIG in for a scan only for it to pick up nothing. Sometime later XIG did receive some sort of reading in the ocean and began to track it. As Bokura came to the shore not far from Gamu and his mother's position. Gamu had to leave his mother for the moment and scout  after Bokurag to let update XIG before he could do any serious damage. Team Lightning fired off many incendiary missiles at the water beast, but due to the fog the monster produced, it did no damage, the only way to defeat him was to evaporate him, which would destroy the city. XIG tried their best, but nothing seemed to do anything beyond annoy Bokurag.


Gamu witnessed Hiroya Fujimiya using the Agulater, revealing that he was Ultraman Agul and planned to stop Bokurag himself. Agul began the attack by launching a hand ball, following up with a beat down and then threw Bokurag into a refinery. As Bokurag tried to retaliate, Agul used the Agul Blade to slice the ancient fish monster into three pieces only for him to regenerate. Bokurag grabbed Agul and began to drain the life from him, quickly setting off his color timer, leaving Gamu no choice but to become Ultraman Gaia. Gaia released a few Gaia Slashes to free Agul from the pincers, but Bokurag simply regenerated them. Gaia kicked Bokurag's head off and he regenerated it back. Bokurag became agitated and began to beat down Gaia and began to drain his energy shortly after. Agul fired the Liquidator, blowing Bokurag to pieces where he couldn't regenerate. Another Giant
