Wave one's hand at target
Power Negation is the ability to cancel out the magical powers of other beings as they are being used. It can also be used to reverse or undo spells as well as nullifying the power of some magical objects.
This power is apparently neutral, being possessed by both good and evil individuals. However, it may be just a benelovent power, as Neena and the Avatars were all benelovent individuals, who honestly thought their actions were for the greater good.
