Asura is a demigod who was once a member of the Eight Guardian Generals, a group of demigods who protect the world from the demonic and destructive Gohma. After destroying Vlitra, the strongest Gohma, Asura is summoned to the palace of Gaia's emperor, only to find that he's been killed and Asura was framed for it. Back at his home, Asura's wife has been killed and his daughter Mithra has been kidnapped by the Guardian Generals, who wish to use her to boost their power so they can save the world. After this revelation, Asura is killed by the leader of the generals, Deus. 12,000 years in the future, Asura's rage has let him climb back into the mortal world, where the generals, now going by the Seven Deities, are using the souls of their human worshipers as fuel to make themselves stronger. Consumed by his rage, Asura goes to kill every member of the Seven Deities and retrieve his daughter.
Mantra of Wrath: Mantra is the power source of every demigod, and it has different affinities based on emotion. Asura's mantra is the Mantra of Wrath, which increases in output the angrier Asura becomes. As such, Asura's power increases with his anger. As a ranged attack, Asura can fire blasts of Mantra from his fists, which range from barrages of weak shots to strong homing blasts, and release shockwaves of it from his body to blow back enemies.
Immense Strength: Due to the Mantra of Wrath, Asura's physical strength is extraordinary. He can subdue Vlitra with three punches, lift the finger of a planet-sized opponent, and punch said finger hard enough to make the planet-sized opponent explode.
Immense Endurance: Because of his rage, Asura has great endurance. He can fight through the pain of being impaled several times to continue a battle, and often fights after losing both of his arms.
Mantra Reactor: The Mantra Reactor from the Karma Fortress used to hold the power of seventy billion souls. Though it lost that power, it still contains all affinities of Mantra. After being rendered comatose during his fight with Chakravartin, Asura's brother-in-law Yasha implanted the Mantra Reactor in his chest as a focusing point for his power. With the Mantra Reactor, Asura can channel the Mantra of Wrath's full power without burning himself out.
Vajra Asura: When fighting opponents on his level, Asura usually transforms into this form, giving him two extra pairs of arms for six in total. This gives Asura a boost of strength.
Berserker/Wrath Asura: When Asura's rage reaches a point where he can't control it, he becomes Berserker Asura, a feral monster with four arms of pure Mantra formed from his back. In this form, Asura can fire beams of Mantra powerful enough to wipe out entire armies of battleships. If he stays in this form for too long, Asura's rage will burn him out, transforming him into Wrath Asura. Wrath Asura is too burned out to use Mantra attacks, relying on rushing down and overpowering foes, but he's so damaged at this point that attacking foes damages him more than his enemies.
Mantra Asura: The highest power the Mantra of Wrath can reach on its own, Mantra Asura combines thousands of arms into Asura's two, making them much bigger and giving one of his strikes the power of hundreds. While in this form, Asura's anger is more focused, and he can vent jets of Mantra from his new arms for better maneuvering and striking power.
Asura the Destructor: By channeling all the power from the Mantra Reactor, Asura becomes the Destructor, a six-armed behemoth larger than the Sun. In this form, Asura is strong enough to punch planets hundreds of times bigger than him to pieces. His Mantra blasts in this form can obliterate stars in one shot. Asura can also condense this form into a smaller form with six Mantra Asura-like arms, but the power of it remains.
