Fanfic Idea: Asura's Wrath and RWBY crossover.
Once Asura kills Chakravartin, all the mantra is lost, including the mantra that Asura needs to survive, however, now that he has saved his daughter and no one else is controlling the world or pulling strings, he feels content and the wrath he's known all his life dissapears just before he does, leaving him at peace in his final moments. Unfortunately, however, Asura is not allowed to rest, for a mysterious figure appears before Asura as he enters the afterlife, telling him that another world needs his strength and resolve to save it from a threat similar to the Gohma he faced in his life and, should he accept, will be returned to life in that world with all his memory and power, but his body will changed slightly so as to blend in. As much as he wants to be reunited with his wife, Durga, Asura can't in good conscience leave a world to be destroyed by the Gohma, and so he reluctantly accepts the deal and is returned to life in the world of Remnant.
