Iron Man: Nexus of Marvel Universes
Tony Stark, ever the innovator, discovers a way to traverse the Multiverse. He detects distress signals from multiple Marvel Universes, including the *Amazing Spider-Man* universe, *Fantastic Four*, and *X-Men* worlds. Stark realizes these universes are facing threats from entities that are too large for any one hero or team to defeat alone. He creates a powerful interdimensional portal using advanced Stark technology and becomes a multiversal hero, traveling between worlds to help.
Along the way, Stark faces the ultimate dilemma: the more he helps, the more he disrupts the balance of these universes. Tony must also confront alternate versions of himself, some heroic, others villainous, and realize that not every version of him can be trusted.
