Ah but at the end of bayenetta she summoned something of similar size(at which point the sound of pants dropping echoed across the world) while asura was able to achieve near equal reality shattering capability to defeat a creator of an entire universe and had the size to match said energy so id say they'd be on equal footing

Sounds like an interesting fight. The thing about Gurren Lagann though, is the harder you hit it, the harder it hits back. The spiral energy that shapes it comes directly from the spirit of those that pilot it, so as long as they have the will to fight, it can just get stronger and stronger. Hell, even without the mech, the guy who pilots it had so much fighting spirit that he was able to fist fight a god and turn his blood into a drill.

True however asura is on frikkin unlimited rage mode even when not the size of a planet on of his punchs obliterated a god the size a planet that and not even being busted up multiple times dieing multiple times and goin into a fight against an army with no arms(literally) and a busted up sword in his mouth or the being thay created that universe could stop him i believe were lookin at a likely permanent stalemate

sounds radical.
