Synopsis
Seven Avengers (Captain America, Captain Marvel (Genis-Vell), Giant-Man, Hawkeye, Songbird, Wasp and Yellowjacket) from various times, along with Rick Jones and Libra, have fled from the destruction of Chronopolis in Kang's Sphinx time machine. They are trying to keep Rick safe from Immortus.
Hawkeye gets angry about Libra's deliberate refusal to tell them what is going on, for fear of upsetting the balance. So Libra pulls one of his vanishing tricks.
Giant-Man and Yellowjacket figure out the Sphinx's controls. They work well together because they are two versions of the same person. Despite Yellowjacket's dislike of Giant-Man.
The destruction of Chronopolis by Immortus caused a chronal anomaly. The Sphinx's sensors detect 3 more chronal anomalies. The Avengers suspect these are more signs of Immortus at work. So Wasp splits them into 3 teams to investigate in chronospheres. They leave Rick in the Sphinx where Immortus can't find him.
Captain America and Giant-Man find themselves in Killraven's War of the Worlds. The original series was an alternate future, and this is another alternate set in the first half of the 21st century. Earth has still been invaded by 'Martians', but in this version Killraven is one of the last of the Avengers, alongside Black Panther, Jocasta, Living Lightning, Thundra and a Crimson Dynamo. They are fighting the cybernetic Skorpsmen.
Hawkeye leads the team of Songbird and Yellowjacket to Tombstone in 1873. They see Kid Colt, Rawhide Kid and Two-Gun Kid fighting a dinosaur conjured up by Kang. Songbird realises they are seeing part of an old Avengers adventure, and that Hawkeye, Moondragon and Thor will soon turn up to sort it out. They plan to leave before they affect history, but find their chronosphere gone.
Captain Marvel and Wasp see Vice-President Nixon in 1959, and Captain Marvel senses he is a Skrull. But they arouse suspicion, and have to face the 1950's Avengers (Gorilla-Man, Human Robot, Marvel Boy, 3-D Man and Venus).
