Some off that is a bit off. 1. Akainu is NOT faster than Marco. 2. He is stronger than Aokiji by a trifle but there's no way for sure to say he's stronger than Kizaru. In fact I think Kizaru is stronger. 3. Changing the weather permanantly has nothing to do with temperature potency. It merely means it has a lasting effect. Also the upper limit of magma cannot be as hot as Yamamoto's heat. Nowhere near. Even if 15 million is not to be taken literally, Alainu doesn't have the incinerating feats Yamamoto does.
