Captain America: Captain America is a fictional character appearing in American comic books published by Marvel Comics.  Created by cartoonists Joe Simon and Jack Kirby, the character first appeared in "Captain America Comics" #1 (cover dated March 1941) from Timely Comics, a predecessor of Marvel Comics.  Captain America was designed as a patriotic supersoldier who often fought the Axis powers of World War II and was Timely Comics' most popular character during the wartime period.  The popularity of superheroes waned following the war and the "Captain America" comic book was discontinued in 1950, with a short-lived revival in 1953.  Since Marvel Comics revived the character in 1964, Captain America has remained in publication.

Death's Head: Death's Head is a fictional character appearing in British comics and American comic books published by Marvel Comics.  The character is depicted as a robotic bounty hunter (or rather, as he calls himself, a "freelance peace-keeping agent").  The character was created by writer Simon Furman and artist Geoff Senior for the company's Marvel UK imprint.  Furman decided to use Death's Head in his Transformers stories, but believed that characters appearing in Transformers "were prone to be absorbed into that title's catchall copyright" (allowing Hasbro to contest their ownership) and led to a one-page strip titled "High Noon Tex" (which was subsequently published in various Marvel UK titles) being hastily created to establish Marvel's ownership of the character.  Furman has stated that he chose the name Death's Head for the character while unaware of the "Nazi-connotations of the name".

Namor: Namor the Sub-Mariner ( ) (Namor McKenzie) is a fictional character appearing in American comic books published by Marvel Comics.  Debuting in early 1939, the character was created by writer-artist Bill Everett for Funnies Inc., one of the first "packagers" in the early days of comic books that supplied comics on demand to publishers looking to enter the new medium.  Initially created for the unreleased comic "Motion Picture Funnies Weekly", the Sub-Mariner first appeared publicly in "Marvel Comics" #1 (cover-dated Oct. 1939) – the first comic book from Timely Comics, the 1930s–1940s predecessor of the company Marvel Comics.  During that period, known to historians and fans as the Golden Age of Comic Books, the Sub-Mariner was one of Timely's top three characters, along with Captain America and the original Human Torch.  Everett said the character's name was inspired by Samuel Taylor Coleridge's poem, "The Rime of the Ancient Mariner".  Everett came up with "Namor" by writing down noble sounding names backwards and thought Roman/Namor looked the best.

Zombie (comics): The Zombie (Simon William Garth) is a fictional supernatural character appearing in American comic books published by Marvel Comics.

The character later became well known for starring in the black-and-white, horror-comic magazine series "Tales of the Zombie" (1973–1975), usually in stories by Steve Gerber and Pablo Marcos.
