As you are well aware Guardians of the Galaxy is the Marvel Studios film this is mainly set in space (95% of it is in space according to Kevin Feige).
The Guardians are a very cool team comprised of Star-Lord, Gamora, Drax, Rocket Raccoon and Groot.
One of the other major space based players of Marvel’s comic book Universe is Nova who is part of the Nova Corps, Marvel’s space cops similar to DC’s Green Lantern Corps.
Originally, the Nova Corps was Xandar’s space militia and exploration division. It consisted of 500 soldiers ranging in rank from Corpsman up to Centurion and its leader, Centurion Nova Prime. The Corps also had a regiment of Syfon Warriors, of which Powerhouse was one. After the reformation of Xandar, the Nova Corps expanded its protective range to include the entire Andromeda Galaxy and Earth. They are also known as the Xandarian StarCorps. Queen Adora (in the role of Prime Commandant) has ultimate authority of the Nova Corps.
The source the Corps’ power is called the Nova Force. This is a nearly limitless energy field generated by the a living supercomputer called the Xandarian Worldmind. The energy is then transmitted into the centurions at varying levels depending on their rank. The Worldmind contains the entire record of Xandarian history and civilization – Marvel Wiki
Richard Rider was the character most associated with Nova in the comics. He had a history with Gamora and many interactions with the Guardians. He also helped them take on Thanos, who we know is involved in some way with the Marvel movies.
Marvel restarted Nova recently with a younger character, Sam Alexander, and the first issue featured Gamora and Rocket Raccoon so there are many links with the Guardians being set up. Iron Man also features in the current roster of the Guardians.
It makes a whole lot of sense for the Nova Corps to feature in the Guardians of the Galaxy film. Even if we just see members of the Corp in the background of scenes.
Who would have ever thought that we would have the possibility of seeing the Guardians of the Galaxy, and now Nova, on the big screen. It is so exciting.
