Dr. Grace Balin is a former marine biologist at Grand Pacific University. One day, she’d gotten into a car accident, leaving her paralyzed from the waist down. Grace would then experiment with orca tissue to regain her mobility, which would lead up to her becoming The Orca she is today. Unfortunately, after her permanent transformation into the anthropomorphic orca, her identity as Grace Balin vanishes, now being replaced by Orca herself. She’s now currently back to researching marine biology.
