At the end of Endgame, we see Thor give up his title as the king of Asgard/New Asgard to Valkyrie to join the Guardians of Galaxy. Obvious Quill is threatened by Thor joining because he is worried that Thor will become the leads of the group. Thor is stronger and bigger anyways. Thor teases that they should call themselves Asgardians of The Galaxy. Turns out this is not a joke. It is a real team in the Marvel comics.
This is a team that was formed are the breakup of The Guardians of Galaxy during “Infinity Countdown” storyline in comics. Asgardians come together to defeat the villain named, Nebula. In the Marvel Cinematic Universe, Nebula becomes a friend. Thor’s long-lost sister Angela join the team as well.
I am going to assume that Asgardians of Galaxy will be a new entry to Phase 4 of MCU. We might expect Guardians of Galaxy Volume 3 to set up the foundation of this.
