Thor is in Manhattan when he stumbles upon a group of terrorists preparing to blow up a nuclear reactor in the name of some unspecified cause. Thor stops the villains, but suddenly he and the nuclear reactor are both teleported away.
What happens to the reactor is unclear, but Thor wakes up floating in space. Without any magical conveyance, Thor is frozen by the cold void of space, although it does not kill him.
In the 31st Century, the Guardians of the Galaxy are a ragtag spaceship crew, fighting for the betterment of Earth. They consist of Yondu, Charlie 27, Martinex, Niki, Starhawk, and Vance Astro. They stumble upon Thor floating in space and rescue him.
Once onboard, Thor agrees to help the Guardians in their fight against a villain named Korvac. Korvac has a plan that involves blowing up Earth’s sun. Thor and the Guardians fight Korvac and his allies. They manage to destroy Korvac’s base, and in defeat, Korvac teleports away. Astro uses a time machine that Korvac apparently owned to send Thor back to the 20th century.
