Marvel Studios Without Dr. Erskine, there would be no Captain America. Played by Stanley Tucci in Captain America: The First Avenger, Erskine creates Captain America in more ways than one.

Erskine's stint in the Marvel Cinematic Universe may have been brief, but he is responsible for one of the most significant scientific creations in the MCU to date.

Dr Abraham Erskine is the creator of the Super-Soldier Serum; he was behind a program to create a line of super-soldiers for America during their World War II campaign.
