Benedict Cumberbatch's Doctor Strange has been confirmed for Avengers: Doomsday. I hope that we get to see him directly fighting Robert Downey Jr.'s Doctor Doom for a simple reason. With the Scarlet Witch dead and Loki holding the multiverse together, Strange is the only sorcerer powerful enough to warrant Marvel Studios showing Doctor Doom's magical expertise from the comics. To defeat Strange, Doom would have to show how gifted a sorcerer he is, which would help make him more different from Tony Stark to fans, which is desperately needed after RDJ's casting.
