He nuked Edo Japan with his Dark Matter, which I believe is city level or higher. And that was done casually, mind you. In terms of raw power, without Truth, I'd say the Earl takes it.(he should also take speed, unless I'm mistaken, as I'm pretty sure DGM just has better speed feats than FMA, reaching well into the hypersonic range, but maybe someone can correct me on that, as I don't really recall anything from the FMA series that's all that impressive speed-wise.) In round two, it goes even worse for FMA, as none of the homunculi or alchemists, sans maybe Pride, due to his nature, have a resistance against the kind of poison that Akuma have, which literally causes disintegration shortly after contact with flesh(this includes with fumes emitted from level 1's missile attacks), with the only thing known to purge it, for the most part, being Innocence, the power used by Exorcists, due to it being the direct counterpart and opposite of the Akuma's main power source of Dark Matter...
