Jack Clark had always suppressed his Godlike form, waiting for the result of the Mythical Impact.
The fate of The Purgatory Family in this battle had been sealed from the moment the Destruction Emperor Dragon's True Body arrived, with the main concern being the Blue Star World.
If he had merged with the Giant Beast Body too early, the overly powerful strength would have been unable to enter Blue Star, and there would have been no way to lend aid should the situation there change.
Now that the Blue Star World was stable, Jack Clark no longer had any concerns holding him back.
Just when he, weakened to his last breath, fell into the maw of the Doomsday Deep Red Emperor Dragon, with the Doomsday Deep Red Emperor Dragon as the core, he initiated Deification.
Silent and unnoticeable, Jack Clark's formidable True Body instantly disintegrated, transforming into a sky-full of blood mist that merged into the Doomsday Deep Red Emperor Dragon.
