The first Ka-Zar was named David Rand, and debuted in 1936, first appearing in pulp magazines of the 1930s.  In 1939 he was adapted for his second iteration, a comic book character for Timely Comics, the 1930s and 1940s predecessor of Marvel Comics.

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.
