Aspen Matthews is caught between two worlds. During her early adolescence, she could remember nothing from her early childhood. In her earliest memories she is on the cruise ship Paradise, thought to have been lost for ten years. She was adopted by Captain Matthews, a captain of the US Navy, and soon developed a passion for water, always barefoot and running to the nearest beach every day to enjoy her favorite recreation of swimming and surfing. She actively pursued this passion and joined the US Olympic Swimming Team. She trained and competed in the Olympic Games, but was later stripped of her medals as she somehow tested positive for performance-enhancing drugs. This effectively ended Aspen's professional swimming career, so she instead pursued marine biology.
