Irani Rael AKA Nova Prime is a character from Marvel Comics.
Irani Rael is the head of the Nova Corps, a military force for the Nova Empire on the planet Xandar. Rael's Nova Corps joined forces with the Guardians of the Galaxy to save Xandar from the mad Kree, Ronan the Accuser.
Around 2014, the Nova Corps joined forces with Stark Industries to create the Xandarian Outpost on Earth as part of his Global Avengers Initiative. The location of this outpost was chosen by Guardian member Star-Lord to be the Experimental Prototype Community of Tomorrow or, "EPCOT" in Florida. Here, the plan would be to show Terrans the wonders of EPCOT before teleporting them onto a Nova Ship captained by Centurion Tal Marik to visit Xandar themselves via a portal from the ship's Cosmic Generator.
When the Terrans were transported onto the Nova Ship, Nova Prime communicated with them only for power to black our on Marik's ship and the Cosmic Generator to go missing. At Nova Prime's request, Marik contacted the Guardians of the Galaxy while they found the generator to have been stolen by the Celestial, "Eson the Searcher" in an effort to rewrite history. The Nova Corps managed to defeat Eson alongside the Guardians and recruited Terrans in Starjumpers.
Nova Prime appears on screens in the pre-show.
