Eric Henderson was a lone child, who grew up along side his foster brother Woody. In his youth he studied hard, and did his best to impress and prove himself to his scientist father. However, he always felt that he was the unfavored son compared to Woody. When Woody decided to abandon the family years later, Eric continued to work hard and decided join the military.
After his time in the military, Eric reunited with Woody upon their father's death from unknown reasons. In an attempt to unravel the mystery behind their father's death, Eric and Woody are imbued with powers. However, to prevent their bodies from dissociating, they must tap bands every 24 hours. Unlike Woody's more destructive energy blasts, Quantum creates shield-like, defensive energy constructs.
