7. Form A Villain Team
Can you imagine how awesome it would be if the likes of Loki, Red Skull, Abomination and Malekith were to come together to form a counter-team to the Avengers? It would rock our worlds. Supervillain teams are a common sight in comic books, but there's yet to really be an appearance from one on the big screen. Sure, we've had "evil" organisations like Hammer Industries and A.I.M, but a supervillain conglomerate is yet to come together. Loki is currently being held captive (though that is due to change in Thor: The Dark World), as is the Abomination, while Red Skull was absorbed in to the Tesseract - so his essence is still out there somewhere - and with villains like the Leader having been hinted at and Thanos being out there, there are plenty of individuals who can join forces for world, or even universal, domination.
