4. Namor, Prince of Atlantis
Namor is one very angry man. He is the prince of the underwater kingdom of Atlantis and fiercely protects it from surface-dwellers. He even invades other countries to seek vengeance on those he thinks have perpetrated wrongs against Atlantis. He is the son of a human sea captain and a mermaid princess, and is stronger than both humans and mermen. He is one of Marvels first heroes and the first known antihero. He has worked with various different heroes and villains when it has suited his purposes, including working with Captain America during World War 2. Even though Namor first appeared in comics in 1939, he is yet to appear in a live action film. The kingdom of Atlantis was however very briefly referenced on a S.H.I.E.L.D. computer in Iron Man 2. No doubt the work of S.H.I.E.L.D. will have disrupted Atlantis and incurred the wrath of Namor. It would be fantastic to see Namor, and indeed the kingdom of Atlantis in the S.H.I.E.L.D. TV show.
