The debut of the Ultimate Marvel Universe was a defining moment in the history of 21st century comic books. After decades of stories, reboots, retcons and continuity shifts, Marvel Comics in the late 1990s were too daunting for any new reader to get into. With new movies coming out based on the most popular characters, Marvel took a back-to-basics approach in 2000 that helped new fans get acclimated with the classic heroes and storylines without having to catch up on nearly 40 years of backstory. The Ultimate Universe would serve as a major template for the Marvel Cinematic Universe.
