In 10,000 AD, Sub Sanders was a member of the US Submarine Forces. He gained the ability to breathe underwater and survive tremendous water pressure of the ocean debts after an unnamed scientist exposed him to unnamed rays. With his water breathing submarine crew, Sub Sanders assisted the Queen Lantida of Atlantis (which, according to the text caption, was a former underwater colony named after the Atlantis of legends). He fought against enemies such as the Octopeople of Ectpoia, the Frog-Men, Kong the undersea pirate, the Serpent Lady, the Ray-Men, Prince Pizga, and many more.
