Power Nullification

Summary
Power Negation. Simply put, it's the ability to cancel out the powers of others, making them unable to utilize their powers as long as they are under the user's affect or within the very presence of the user him/her/itself.

Capabilities
The main capabilities of power negation is that one can either weaken or nullify another ones powers. Ways they can do this is that they can either do this by simply touching the person, releasing a nullifying wave attack, creating a nullification zone, or even by just being within the users presence.

Weaknesses
Weaknesses to using this ability, however, are that the user is only capable to weakening a power, another would be some powers might not be negated, and a third would be that the powers are temporarily negated(only effective so long as they are within the users presence).
