Character Description:
Samuel Alexander, Sam for short, is a 15-year-old male from the very small town of Carefree, Arizona. He lives with his parents, his father who is Jesse Alexander, and his younger sister. Sam’s father, Jesse, always told him and his sister stories of his adventures in space and stories about the Nova Corps. However, Jesse was known as a drunk and very delusional, Sam never believed his stories. These suspicions are put to rest when his father goes missing, and Sam goes searching for him. While searching, Sam gets into an accident which leads him to wake up in the hospital, where he is greeted by Gamora and Rocket Raccoon. They inform Sam of his father's true legacy as a member of the Nova Corps, leaving Sam his helmet.

Personality:
Sam is still very young, making him act immaturely in some situations. He is laid back, but full of himself. However, he is actually very insecure and inexperienced. Sam also can be very arrogant due to his powerful abilities. He does have a deep love for his friends and family. He thinks of his father as a loser but still cares for him deeply. Sam can also speak some Spanish due to his mother using the language frequently.

Voice:
Sam is self-confident, a little too overconfident for a matter of fact. He is young and ends up being arrogant, full of himself, and childlike most times. Someone with a slightly higher pitched, male, American teenager voice is needed. This is a lead role perfect for someone who can portray this witty, bold, powerful but childlike young male.
