Are Avengers: Age of Ultron’s Quicksilver and Scarlet Witch Actually Inhumans?

One of those properties was The Inhumans, powerful but lesser-used characters created during Stan Lee and Jack Kirby’s legendary run on The Fantastic Four. They’ll have their own movie coming in 2018, but — as with characters like Black Panther and Doctor Strange, who were teased well before they actually appeared onscreen, studio brass says that The Inhumans won’t be referenced for the first time in their own solo feature.

“Where [The Inhumans] fit into the universe, you will find out sooner than you expect,” Marvel Studios chief Kevin Feige said during their presentaiton today.

Could that be…as soon as Avengers: Age of Ultron?

In the comics, it has been widely speculated that Quicksilver and Scarlet Witch — characters jointly owned by Disney and Fox for the movies — are in fact Inhumans and not mutants, as has long been believed. Quicksilver made his first-ever live action appearance in a cameo at the end of Captain America: The Winter Soldier, had a larger role in X-Men: Days of Future Past and will appear in a larger role still in Avengers: Age of Ultron, although Days of Future Past is not set in the same world as the Marvel Studios movies.
