The standard "Super" power limitation is composed of -5% for the existence of "anti-powers", paranormal abilities that can cancel abilities with it, and -5% for power-neutralizing technology. The first would definitely include Static and Neutralize, but would also include things like Affliction (Negated Advantage, Flight with the Super limitation) and other builds like that. The second means that it's possible to build devices and technology that can shut down abilities that anyone with the appropriate technical training can use.
So if Super, -10% is a thing you allow in your setting, it implies that characters like
Rogue or
Leech exist in the setting, and that even enemies without superpowers of their own could deploy "power dampeners" or something like that to potentially shut down the heroes' abilities.
As to how to deploy them, bear in mind that you don't have to build everything with points, particularly if they're not characters at all, but rather equipment. You can just say that Null-Woman emits a power-dampening field that forces everyone within 100 yards to roll against Will or lose all their abilities with the Super limitation, without specifically working out how much that would cost or which modifiers to use on the Neutralize ability.
