Polaris is an ex-military soldier with a lifetime contract with Apple-Mercedes, in exchange for a set of proprietary prosthetic "running blade" replacement cyberlegs. She has a strong personal ethics regarding safeguarding (or not endangering) civilian lives.
 
She served with the Mercedes Special Operations Group for some time before an accident ended her career with the prestigious organization and left her with cybernetic legs. She would later find out that the loss of her legs was partially due an unsuccessful experimental cybernetics procedure cleared by her boss Major Elise de Villier.
 
She currently remains in the employ of Apple-Mercedes, paying off her lifesaving cybernetics procedure. Recently, she has also invested significantly into the affiliated Zest multi-level marketing franchise, launching it into a successful venture in the SEA region.
 
In July 2020, she was briefly detained by Certis after the chaos of Boeing Parade Incident, where she raised the alarm to evacuate endangered VIPs before taking down one of the rogue mechs with a well placed explosive.
