Cyber-Knight

Origin
A former FBI agent, and former partner of Rod Stiner (aka Jackpott). Mario Sanchez was with Stiner in the botched mob bust, and ended up severely damaging both his arms and his legs. After having his limbs replaced with cybernetic ones, he opted to employ his new appendages - and his martial arts expertise - in the services of the highest bidder.
