Subtitle: Giant-beast (巨獣 Kyojū)
As Ultraman Gaia and Agul were fighting, a wormhole formed, absorbing the energy they were giving off. After the fight ended in a draw, the wormhole, now called worm zone, began disrupting weather conditions. Team Lightning, Falcon, and Crow were launched and as they approached the portal Zoruim popped his head out, and fired his flame breath to cause wanton destruction on the people below. XIG's attacks didn't even get his attention. After finding out the truth of his computer: Crisis having been corrupted by the Roots of Destruction, Hiroya gave Gamu the energy of Agul because he felt unable to protect the earth after all he had done. As he went off Zoruim's flames exploded around him, and he disappeared. To insure his sacrifice wasn't in vain, Gamu turned into a new and improved Ultraman Gaia: Gaia Version 2. The new form headed for Zoruim and used his Quantum Stream, but it did little than annoy him. Shortly after Gaia turned into Supreme Version, went inside Zoruim, and used the Photon Stream to blow the monster's skull to pieces. The worm zone closed just seconds after.
