Life and death

Mic will have to periodically power up at an outlet or steal juice from the batteries of his foes. Every action he takes will require a certain amount of energy (some more than others) and will drain his battery. If he ever completely runs out of energy he will shutdown and become permanently imobilized thus failing in his mission.

outlets and batteries: full / partial charging
