10 Key Marvel Cinematic Universe Questions That Must Be Answered In Phase 3

7. Is Hulk A Danger?

This may actually be answered in phase two but, if it's not, we definitely need it to be answered during phase three. Bruce Banner has displayed signs of both being able to control his transformation in to the big green rage monster, as well as vulnerability when it comes to an involuntary change. Although the latter was caused by trauma beyond his control (when the S.H.I.E.L.D. Helicarrier was attacked in the Avengers movie), it still potentially poses a threat to those around him if he can turn in to the Hulk in any potential given scenario and not care who he attacks once the transformation is complete. So we need closure on the matter. Is Hulk a threat to his fellow heroes or not? It's important because it could potentially lead to Hulk being banished from Earth, which could end up with a Planet Hulk/World War Hulk storyline in the Marvel Cinematic Universe - and that would be awesome.
