On the heels of news about Marvel’s new female Thor and word tonight that Sam Wilson will be taking over the mantle of Captain America from Steve Rogers, comes confirmation (via EW) that both Avengers will be assembling this fall in a new book, “Avengers NOW!”
The new Thor and Captain America will join a team that will also feature a new Iron Man suit, although it will still be worn by Tony Stark. “The Superior Iron Man” will follow Tony in his new life in San Francisco.
“Like the Superior Spider-Man, Superior Iron Man is a character that’s hard to root for,” Marvel’s Axel Alonso teases.
The new Avengers team, as shown below, will include, in addition to Iron Man, Thor and Captain America, Medusa, Scarlet Witch, Winter Soldier, Angela, Doctor Strange, Ant-Man, Deathlok and Inferno.
