Robert Bruce Banner, M.D., Ph.D. is a renowned scientist who was highly respected for all his work in the fields of BiochemistryNuclear Physics, and Gamma Radiation. Having been tasked by General Thaddeus Ross to find a way to recreate the Super Soldier Serum which had originated Captain America, Banner conducted an experiment with Gamma Radiation. However, when an exposure to high levels of Gamma Radiation instead of Vita Radiation went awry, the mild-mannered scientist had found that when angered or provoked, he would transform into the huge, rage-fueled, nearly mindless and green-skinned monster known as Hulk.


Same as Spider-Man, he did not appear in the movie but his alter-ego was said by Wade in the trailer and the movie when he reveals his real name.
