Some of you may recall the uproar that stemmed from Marvel's decision to make the new Ultimate version of Spider-Man a teen of mixed ethnic heritage. Miles Morales is half African American and half Latino, but he's all-fan when it comes to Peter Parker, the white teen who was the original Ultimate Spider-Man and who remains the eponymous web slinger in Marvel's 656 universe (albeit no longer a teen). Morales only knows the Ultimate version, though, who was killed last year.
Despite the fact that Morales is a great character and respectful of the Spidey legacy, some will never be happy with him simply because he's "of color."
So, it makes me very happy to see that Marvel is going to let the "original original" Spider-Man meet the latest. It's going to be a little subversive slap in the face to the haters when these two hit it off. :)
