Gigantex the Colossus is a Reploid who was apparently made to restore Earth after the fall of the space colony Eurasia, but was deactivated at some point. However, Saturn discovered about his existence and somehow got inside the huge hangar in which Gigantex was sealed. As soon as Saturn got inside the place, he began wrapping Gigantex with his Green Mist in order to reactivate his body devices. Saturn brought both in front of the main headquarters of the Maverick Hunters with a stronger warp technique, awakening Gigantex simultaneously, and began what he called the Operation Doomsday. The giant began attacking the Hunters HQ in berserk and the Maverick Hunters did not have enough time to react to his violent strikes, which soon made the building collapse and kill nearly all of them. Shortly before being dying, one of the Rookie Hunters noticed Gigantex's arms could be destroyed by hitting the gems from which his devastating lasers are shot. When X and Zero finally arrived to rescue their allies, the headquarters was in ruins and Gigantex was still unsatisfied with the amount of destruction he caused. Saturn decided to withdraw and used the remaining energy he had to warp himself, Shad and Gigantex to somewhere else.

After the Parade, the Mysterious Man questions Saturn about his deranged methods of achieving his goals, and Saturn implies that he will use Gigantex one more time to destroy the main headquarters of the government.

During Awareness, a scene shows the silhouette of Gigantex working with mechaniloids and Repliforce officers in a destroyed city months after the fall of Eurasia.
