Avengers vs X-Men
The new Nova (Sam Alexander) first appeared while trying to warn the cosmic dictator Terrax of a massive threat approaching his home world of Birj. Instead of listening, however, Terrax decided to fight with Sam before rejecting the warning, forcing the young hero to flee.
Soon after, Phoenix Force arrived and destroyed the planet of Birj as Nova had predicted. Sam sped off towards Earth to warn the planet of the approaching Phoenix Force. Pushing himself to his limits, Sam revealed that he was originally from the Midwest and that he was relatively new to being part of the Nova Corps.
As he approached the Earth, Sam accidentally missed the downshift required to make a steady descent and found himself unable to control himself as his rate of descent increased beyond exponentially.
The situation deteriorated quickly when Sam accidentally tore through both the wing of a commercial jet and broke off the upper levels of the Chrysler Building. Though Sam managed to swerve around an oncoming news chopper, he could not stop himself from slamming into several more buildings in the downtown area.
The Avengers, who had just finished averting the even greater disasters that could have been caused by the falling plane and the top portion of the Chrysler Building, found a heavily disoriented Sam laying in a smoldering crater.
When Sam realized that the Avengers were standing over him, he tried to tell them of the coming danger, but could only manage "It's coming..." before falling into a coma. The Avengers hurried Sam to a hospital.
In the final issue of AVX, Sam managed to tackle Cyclops in the final battle. For his actions in the event, Thor invites him to join The Avengers.
In Other Media
Sam is a main character in Ultimate Spider-Man, and one of the trainees being mentored by Nick Fury and the SHIELD organization. In the hour-long pilot episode, Nova is initially shown to be very hostile towards Spider-Man, and actively complains about his inclusion in the SHIELD training program. He is shown to be somewhat arrogant. He has a high opinion on his powers and believes he is the teams leader and that his opinions carry more weight than they do, such as when he objected to spiderman joining the team. He also has a heated rivalry with Spider-Man from the moment they first met, constantly seeking to outdo each other. He has shown the same abilities he has in the comics, a high degree of energy manipulating abilities such as being able to shoot beams and incase himself in an aura that allows him to destroy objects such as the falling pieces a video screen that were about to crush a crowed, though he was unaware of his ability to absorb energy until the battle with the doombots aboard the hellicarrier. Out of costume he has shown somewhat odd behavior, such as carving a replica of principle Coulson's head out of mashed potatoes.
Sam's costume is available as an alternate outfit for the Richard Rider version of Nova in Ultimate Marvel vs. Capcom 3.
