15 Best Scientists In The MCU
4. Bruce Banner
The man with seven PHDs. Bruce Banner is one of the world's leaders in nuclear physics and biochemistry.
Banner's greatest creation lies within himself. Bruce is the world's authority on gamma radiation. In an attempt to replicate the serum that turned Steve Rogers into Captain America, he accidently turns himself in the giant green rage monster, the Hulk. In fairness to Banner, General Ross and the United States military didn't tell him exactly how his work would be applied, which seems like a significant bit of info to withhold.
The experiment could be seen as a failure, but in truth Banner's work yielded an incredible (no pun intended) result. The Hulk is a being of immense strength, speed and durability far exceeding the work of Project Rebuild. Banner, until Thor: Ragnarok, had even shown an ability to somewhat tame the Hulk.
Although we think of him as a chemist, physicist and biologist, he has shown prowess with computer science and engineering as well. He helped create the Hulkbuster and even Ultron himself.
Bruce Banner's brain is the perfect counterpart for the Hulk's brawn. Hulk may be the strongest Avenger, but Banner may be the brightest.
