This is a multi-galaxy buster(Asura)
After Yasha fitted Asura with the Mantra Reactor, Asura's body became capable of safely harnessing any amount of Mantra he could generate. When Chakravartin attempted to destroy Gaia with a powerful blast of Mantra, Asura stood in from of it and took the brunt of the attack, assuming the form of The Destructor. In this form, he
becomes larger than Gaia itself, his skin becomes grey-colored and he manifests six arms identical in appearance to those of his Mantra form. His power in this stage is immense and godlike in status, as during his battle with the Mantra God, his blasts destroyed multiple stars and planets and was able to punch a planet at least a hundred times bigger than him to the point where it broke apart.
