Ultra Cooler's Fusion Form

Ultra Cooler's Fusion Form is a combination of Cooler 16's Cosmic Evolution, Jeiyu's Self-Dark Evolution, Janesuka's Malefic Form (and Dark Evolution), Slugack's Mastered Red-Eyed Form, and Hatchiyarles Super Saiyan form (altered due to his base form being a Fusion form of Turles' Out of Control form and Hatchiyack's Dark Machine form).

Overview
Ultra Cooler's fusion form puts at him a level far beyond even Vegeks' power as he was able to repel all his attacks. As result of this form; Ultra Cooler is always effected by attacks that are based on an evil heart due to his constant Super Saiyan form that is apart of his Fusion form. It is hinted by Chronoa that since Ultra Cooler made his fusion permanent; the form can be passed on if he were to have child as he now technically a Bio-Android/New-Type Android creature.

History
Ultra Cooler used this form through out his entire appearance even when in his transformed states. He is able to achieve Great Ape and Ultimate Great Ape forms while being able to control his transformation remain in the Great Ape form rather than becoming a Golden Great Ape.

After Ultra Gogeta defused; Ultra Cooler manifested a Freeform Fusion station and used it to fuse with Ultra Gogeta from a parallel time and absorbed, and gained Ultra Gogeta's Fusion form. As result; his power magnified to an unprecedented level.

However, all this was reversed after Chronoa asks Dori to undo the events by going to the start of the battle, but Zeno intervened and erased Ultra Cooler himself.

Freeform fusion with Ultra Gogeta
After using the Freeform fusion; Ultra Cooler not only absorbed Ultra Gogeta's power but also gained his Fusion form and thus combined it with his own.
