This post is inspired by a post by another Moviepilot, Frederick Crew, and one of the ideas he suggested. I'm merely expanding on one of the ideas. Hercules is a fairly popular Marvel character, and would be a wonderful addition to the Cinematic Universe.
This is how we should meet him:
Avengers 2: Age of Ultron
Similar to the first Avengers, Hulk gets chucked into some random location. But this is no mere random location. This is the Parthenon, in Greece. Hulk begins going on a rage-fueled rampage through the area, and many Greeks begin praying for some sort of savior. Enter Hercules. Hercules and the Green Goliath get into fierce battle, and Hercules finally temporarily subdues Hulk when he reverts back to Banner. The Avengers reacquire Dr. Banner, and seeing the destruction he has caused, boot him off to space.
There. I have introduced Hercules, and at the same time set up Planet/World War Hulk.
What do you think pilots? Would you like to see Hercules in [The Avengers: Age Of Ultron](movie:293035). Hit me up in the comments below!
