Biography
Sam Alexander is a sixteen-year-old living in Carefree, Arizona with his father, mother, and little sister. His father is always drunk and often talks about his supposed life as a Nova Centurion, and shirks his duties as janitor at his son's school. Sam's mother is a Latina homemaker. When Sam comes home from school to find his father missing, Sam accidentally injures himself and wakes up in a hospital. There, Rocket Raccoon and Gamora reveal Sam's father really was in the Nova Corps. After putting on his father's helmet, Sam travels to the moon, meeting Uatu the Watcher, who reveals an invasion fleet of alien ships belonging to the Chitauri. Upon returning to Earth, Rocket Raccoon and Gamora train him and tell him to scout the fleet.

Sometime later, Sam is on a mission to warn planets in the path of Dark Phoenix is coming for them. He crashes on Earth, but is able to deliver the warning to the Avengers. After recovering, Nova joins the Avengers and the X-Men against Cyclops, who has become the new Dark Phoenix after Jean Grey. Thor asks Sam to join the Avengers, and Sam eventually accepts. Afterwards, he encounters the previous Nova's recurring enemy Diamondhead, but easily defeats him.

During the events of "Infinity", Sam learns from his crush, Carrie, that she knows he is Nova. Shocked, he flies into the sky, but accidentally removes his helmet and lands in a coma. He wakes up to Justice and Speedball, who offer him a spot on the New Warriors. He next faces off against Kaldera, an agent of Proxima Midnight and defeats her in combat. Sam becomes cocky and prideful and begins to feel above the New Warriors and disregard his mother's rules. He gets into an argument with Carrie and gets mad at Justice and Speedball. He eventually speaks to Uatu who gives Sam some advice and he returns to Earth to agree to his mother's rules and joins the New Warriors.

During a day of training with Uatu at the Watcher's moon base at the start of the "Original Sin" storyline, Uatu reveals that Sam's father Jesse Alexander is alive. Sam leaves where he is happy with the information he just learned.

Following the Civil War II storyline, Sam leaves the Avengers to join the Champions led by Ms. Marvel. The team heads to Lasibad, Sharzad to rescue a group of women and girls being attacked by terrorists.
