I've been reading a lot into this. Seems that we will see our Marvel Heros again. Thor, Iron Man, Hulk, Captain America, Scarlet Witch, Hawkeye, Black Widow, and Ant Man....so it seems. We won't be seeing Loki for a while and they will be introducing Tony Stark's Hulk Buster Armor. Sounds like its going to be a good movie. I don't know the full scoop on the story. Not much to nothing. But I can't wait to see my all time favorite marvel hero, Thor bashing his opponents around with Mjonir and maybe get to see his mortal girl friend Jane. After all we got to see Pepper in the first one, and Iron Man got more screen time. Perhaps it will focus more on Thor this time.
I have looked in to Ultron. He reminds me quite a bit like Skynet from Terminator on how he can infect other machines and grow new bodies. I don't see how he'll be more powerful than Loki or , Dr. Doom or Thanos. I'm sure I will learn more about him as time passes. He must be very powerful if he's to be th villain in Avengers 2 . If anyone knows more. Please share. Thank you.
P.S
I really enjoy spoilers, so if anyone knows anything about the plot. By all means share your findings.
