Birthplace Lungmen Aak is a Feline underground/unlicensed doctor from Lungmen and affiliated with Lee's Detective Agency, Aak's medical practices can be said as... extreme and questionable, but proves to be effective. Nevertheless, Aak is a valuable asset for Rhodes Island who accepted his service under the Agency's recommendation as both a medical researcher and occassional field support unit utilizing combat drugs to bolster his allies' performance.
