I wonder if power can be drained, I mean if V transfer power then Why can it not be drained?????????????? But if he is drained of Power then it would be better to just kill him, Remember V most powerful weapon is Arvada kavada it is his power over peoples minds. He is manipulator most of all just look at the way he talks to his subject as if they were his children , and how happy they get when he is in the least bit kind to them. If he were a muggle he would be one of those cults you see on TV drinking Poisoned Cool aid
