From USA Today:
Not going to lie...Miles Morales is an awesome name. Who's next, Doctor Pulpo?
Revealed in Marvel Comics' Ultimate Fallout Issue 4, out Wednesday, the new Spider-Man in the Ultimate universe is a half-black, half-Hispanic teen named Miles Morales. He takes over the gig held by Peter Parker, who was killed in Ultimate Spider-Man Issue 160 in June.
"What you have is a Spider-Man for the 21st century who's reflective of our culture and diversity. We think that readers will fall in love with Miles Morales the same way they fell in love with Peter Parker."
