I was watching Ultimates from where avengers the 2012 blockbuster is made with a little change in script.I liked the story and the 74 minute animation and liked to showcase what I thought of the movie.
It starts with Captain America or Steve Rogers trying to attack and guide his men into the Nazi camp. He meets Herr Kleiser the shape shifter and belonged to Chitauri race but he has taken form of a SS officer. Captain America fights with him and stops the missile from launch by putting a grenade in it and destroying the nuclear missile with the spaceships covering it and kleiser. But even he faces the impact and soon falls of in waters of North Atlantic and thought to be dead .
