Mahasura

Mahasura is one of the forms seen in Asura Wrath 2. This form is different from the other humanoid form of Asura. Mahasura form actually is an exploding energy that expand for eternity. It has reddish colour scheme since it came from Asura's mantra affinity. Aside from just a normal explosion, it has thousand heads of Asura shaped look and another thousand arm holding his Spear of Creation. In the final stage of his expansion he is the size of the 4,754,325,653,775,432,864,234th omniverse level. He is the third largest being in Asura Wrath, probably the third largest being in all of fiction.

Info
While battling Parabrahman Asura decided to activate a bigger form to battle him. He gathered all his power, strength, and energy to turn into his Mahasura form.

Trivia
The only possible reason that Asura could achieve this form is because he and Brahman are actually one being. Mahasura is actually the infinitesmall part of 'Brahman' that have the consciousness of Asura. This connection is similar with the connection of Brahman with Deouxformazanzsicar.
