Andrew Jones was a crippled jockey who was selected by an agency known as the Stable to undergo genetic therapy and had his DNA spliced with that of a horse and could walk again.

She later met Cutter Sharp and married him in hopes of finding peace, but it that didn't take and she left him. She started using drugs, and her life went downwards. Eventually, she left drugs for a new addiction: the adrenaline of extreme-sports, and tried every reckless thing she could think of. Finally, she opted to climb Mt. Everest alone. Along the way, she fell and broke her legs, unable to save herself from freezing to death.
While on the run, Andrew Jones found Andrea and attempted to save her. Unfortunately, he failed, and could only shield her from the cold as he died. However, his body merged with Andrea's, saving her life and granting her his powers and the ability to shapeshift into her savior's form. In honor of Andrew, Andrea renamed herself to Andy Jones, and took off.
