Captain America Joins The Avengers Still smarting from his defeat at the hands of The Avengers (last issue), Namor The Sub-Mariner begins searching for his people who deserted him after the events of Fantastic Four Annual #1. During his search he comes across an Eskimo tribe who are worshiping a mysterious figure frozen in ice. Namor callously tosses their idol into the ocean and swims away. The Avengers are testing out their new submarine and they find the man in the ice, bringing him aboard the sub.
The man in the ice awakens and reveals that he is Captain America who disappeared shortly before the end of World War II. The Avengers are set to introduce Cap to a waiting press corps when they are suddenly turned into stone statues. Captain America and Rick Jones team up to track down the mysterious villain. Cap and Rick eventually find the mystery bad guy who is an alien, trapped on earth. He turned the avengers to stone after making a deal with Sub-Mariner to free his trapped spacecraft.
Captain America and Rick Jones convince the alien to restore The Avengers, and together the team frees the alien spacecraft from the ocean floor. While the alien is making repairs, The Sub-Mariner again attacks, this time with help from his imperial guard. The battle is interrupted by the launch of the alien spacecraft, finally escaping its prison. The Sub-Mariner makes his escape back to the sea.
