Los Vengadores #4

In "Capitán América se une a los Vengadores," the team’s submarine rescue mission takes a shocking turn when they pull the frozen Captain America from the depths—20 years after his disappearance. Back in New York, the Avengers are petrified, forcing Captain America and Rick Jones to uncover the truth behind the attack: a stranded alien whose desperate plea for help was promised by Namor, now threatening to destroy the team unless his ship is freed. With the help of the Atlantean prince and his warriors, the Avengers must confront both the alien’s wrath and the consequences of a broken vow. Cover by Jack Kirby and George Roussos.
