It looks like Marvel killed off Peter Parker in Ultimate Spider Man (don't worry true-believers, hes still alive in "The Amazing Spider Man") and replaced him with a half-Hispanic-half-black alternate named Miles Morales. I'm pretty indifferent, I never liked Ultimate because it gives marvel an excuse to do massive retcons without alienating their fan base, but then again I am glad they have 2 seperate universes so this doesn't happen to my main man Peter.
