I gotta say. Marvel's efforts to bring their property to the Japanese audience is not exactly paying off. With low sales, continued hatred against anything non-Japanese, and "OH HEY THAT STORM IS SEXY!!" But IMMHO, what's created between Marvel and Madhouse continues to be the bright spot amongst the garbage of animu created for pedophiles, NEETs, players of virtual novels, haters of real life, and jerks in general. There was a lot of stuff that (didn't) happen: Sunfire (another Japanese mutant) didn't appear. The "guest appearances" didn't take up a good chunk of an episode like Logan did in Ironman and Cyclops did in "Certain MutantLogan." And didn't Xavier had another son named David? (You know... Chuck seems to "get around" a lot for someone stuck on a wheelchair. :P )

I mean, hey. The Marvel universe, along with the DC universe as well, is filled with so many stories, back-stories, and stories on top of stories; that it would probably take a person half a lifetime to keep track of them all.

And whilst the otaku industry is creating the new hot chick to fap to, the industry representing Marvel is doing the opposite; creating the next (non-)mutant to relate and give life to via recognition. (Sorta like Transformers.)
