The stories and characters of Ultimate Marvel have been adapted to reflect the differences between the present and past continuities, most of which were created in the 1960s and 1970s. For example, Ultimate Spider-Man gains his superpowers from a genetically-engineered spider rather than a radioactive spider, and his alter ego, Peter Parker, originally a photographer for the Daily Bugle newspaper, now has a part-time job as the paper's webmaster. Another noteworthy aspect of the Ultimate Marvel universe is that many of the characters are more youthful than their regular-continuity counterparts. In some cases, this is simply a result of taking the characters back to their origins - Spider-Man, The Human Torch, and the X-Men were teenagers at the beginning of their respective series - but other cases involve more striking changes. In particular, the backstory of the Ultimate Fantastic Four has been compressed so that they gain their powers when Reed Richards, the eldest, is only twenty-one years old. The Marvel Ultimate world is essentially the movies version. It's edgier. Characters are different (or very similar), things that would never be considered mainstream are tried in this world, and characters no matter how popular can die.
