Bio Leech is a highly refined and deadly variation of Electric Drain which allows user to drain or "leech" a victim’s bio-electric, an action that results in the death of the victim as the nervous system runs off of neuro-electrical pulses.
The leeched energy acts just like the energy sucked from either the earth or atmospheric sources using Electric Drain, the energy will heal user completely and will recharge all his power. Although the energy will heal and recharge user almost instantly, it would be unwise to perform this technique in the heat of combat, due to fact that user is extremely vulnerable during the action.
