The ultimate Zetton created by Alien Bat.

Initially taking the form of a Cocoon, composed of several different kaiju and space life forms gathered by the Alien Bat, it absorbs the screams of despair of the remaining humans on Earth. This leads to the awakening of its true form.

Its Gigant form has multi-segmented legs and a hard exoskeleton and can release the high energy Fireballs of Darkness from the luminous part of its back. It attacks Team U’s camp from such a long distance it can’t even be seen. Not only that, but it is able to defeat the Ultras by using its front claws, the Gigantis Claws.

After the juvenile form of Hyper Zetton, Gigant, is defeated by the Ultras, Alien Bat merges with it and his spaceship, resulting in the birth of Imago. Though it's smaller than Gigant, it's incomparably faster. It also possesses retractable wings which allow it to fly at high speeds. Besides the Fireballs of Darkness, it also possesses the ability to teleport in the blink of an eye using the Hyper Zetton Teleport and to defend itself against the Ultras' attacks by using the Hyper Zetton Barrier. Not only that, but it is also able to absorb the Ultra Heroes’ Combo Beam and amplify its power before using it against them.
