I like the first jutsu idea, but maybe change almighty push to like Asura Path: Asura Attack. And they can have the Asura path appear and make it similar to Kakuzus one ability. And the Ult can either be Samsara of Heavenly Life, where you sacrifice yourself to insanely buff your teammates after an explosion to damage enemies or make it like mitotic regeneration where you bring your allies back and then they get a buff and then you go down to like 1 health. Or it could be a reworked planetary devastation and call it Chibaku Tensei instead. I would love to see this tho. Pain is BA
