Sub-Mariner

Origin
Namor was a human/Atlantean hybrid and royal prince. He ran afoul of some surface-dwellers and, after killing them and taking their bodies to Atlantis, was commended for his deed by his mother, Princess Fen, and told to deliver the bodies to their own kind so they could see the beginning of Atlantis' revenge against the humans.

Powers
In his first appearance, the character was introduced as "An ultra-man of the deep... Lives on land and in the sea... Flies in the air... Has the strength of a thousand men... Is a youth of dynamic personality... Quick thought and fast action... From whence does he come and what is his mission?"
