Part of the extended Marvel Multiverse, this world is an extensive universe focused on New York, the city and state, of Earth-1610 (aka Ultimate Marvel). This Earth is very similar to modern day Earth, but with super beings!
Type: BudEarth-1610 is part of a greater universe that has both high technology and advanced magic. While Earth itself appears to be 20th century normal at first glance even there it is possible to find users of magic and makers of high technology in pockets. Beyond Earth there are many other examples of both in this dimension.
Although never publicly acknowledged as such, the material called "unstable molecules" in most iterations of the Marvel Universe exists on Earth-1610. In this world, one instance of their discovery occurred at the Baxter Building - possibly by Reed Richards, possibly by other students before the accident that gave him and the rest of the Fantastic Four powers. This adaptive material has been used in many ways but the most common is for costuming super beings. Its availability is limited to people with ties to the US government, S.H.I.E.L.D., foreign governments (allies or those who could get it via espionage) or off-world sources.
Costumes made of this material have three unique functions: a passive immunity to its wearer's powers (this is why Johnny Storm's costume doesn't burn and Sue's turns invisible with her), a passive self-repair which returns it to its default state over a period of many hours (this is why super beings don't have to budget weekly - or daily! - costume replacements), and, if designed to do so, can be reconfigured to almost any appearance on the fly (OOC Note: this last capability requires a perk stating the character has this ability to use it during scenes).
