Other Info
Rhomann Dey was the leader (Nova-Prime) of the Nova Corps of Xandar. In fact, he was the Nova-Prime when the Luphomoid Warlord named Zorr attacked Xandar. Zorr also began syphoning the energy from the planet to use against Galactus (who destroyed the Luphomoid's homeworld). The Nova Corps fought against him; however, Zorr was too much for Corps and he defeated them. Seemingly all of the Xandarians were killed in the attack, including Dey's wife and children. As one of the last survivors, Dey swore vengeance on Zorr and chased him across the galaxy, battling him from one star system to the next. However, Zorr was too powerful for Dey and the Nova-Prime was eventually mortally wounded the Warlord.

Afterward, with his remaining energy, Dey flew to Earth ahead of Zorr (who was planning Earth as his new target) to seek a replacement who could stop Zorr and make him pay for his crimes. The Nova-Prime ended up choosing the teenager Richard Rider as the new Nova transferring the Nova-Power to him. In addition, Dey linked minds with Rider and explained to him the new powers he had received. He also, explained the threat of Zorr on his planet, Earth. At first, Rider thought the encounter was a dream, but soon discovered his powers and accepted his role as "Nova."  (To learn about Nova, click on the highlighted name above.)

Soon after, while testing his powers for first time, Nova ran into Zorr who was on a rampage in New York City. Deciding to fulfill the one who granted him his powers dying wish, Nova went up against Zorr. However, during the ensuing battle, Zorr was teleported away by Rhomann Dey himself. And it was Dey who killed Zorr with the remaining powers he had before he himself died as well, ready to join his family and friends in the afterlife. 

There isn't anything there, but here is the Marvel.com link to Rhomann Dey's bio, http://marvel.com/universe/Nova-Prime_%28Rhomann_Dey%29.

In the film, Guardians of the Galaxy, Rhomman Dey is credited as "Corpsman Dey." However, in the comics he achieved the ranking of Centurion and was apparently chosen at some point as the Nova Corps leader, Nova-Prime. Will he become Nova-Prime in future Marvel movies? Only time will tell.
