Captain America

From: toonarific.com
The Marvel Superheroes consisted of five different segments, each starring a well-known superhero from a particular Marvel comic - The Sub-Mariner, Captain America, The Incredible Hulk, Iron Man, and Thor.

Steve Rogers (a.k.a Captain America) was a skinny World War II G.I. who volunteered to be a guinea pig for an experimental "super soldier serum." After taking the drug, Steve was endowed with heightened strength, speed, and agility, making him the finest specimen the human race had to offer. With the use of his new-found powers and a nearly indestructible shield, Captain America battled super villains like the Red Skull, as well as an inexhaustible supply of Nazi soldiers.
