It is unknown what backstory/early life this version of Spider-Man has up until he teamed up with the likes of Capcom characters to defeat "Abyss" in Marvel vs. Capcom 2. Over a decade later in Marvel vs. Capcom 3, Doctor Doom and a group of other supervillains joined forces with Wesker, a villain from the Capcom universe, in an attempt to obtain the power of Galactus. They merged the two universes together, and with no clear attacker, both universes assumed the other was invading.
