Ancillary franchise member. America joined the Young Avengers in Young Avengers (2nd series) #5.
Originally, America Chavez's power supposedly arose from a unique mixed heritage. Her mother Elena came from the Utopian Parallel, a dimension where William Kaplan ascended to become the new Demiurge, and all residents were saturated with his power. Her mother Amalia came from Fuertona, a planet created and empowered by the love of cosmic beings Berraca and Sanar. Each world was virtually unique in the Multiverse, and a child born with the power of both worlds was phenomenally potent.
However, America Chavez: Made in the USA #1-5 retconed her origins substantially. Now America was a non-powered native of Earth-616 whose abilities came from an experiment tapping an extra-dimensional power source to cure her of a degenerative medical syndrome when she was a child.
