Invisibility, with ability to hide IR and sound and can make recording video cameras invisible too. I'd expose all the corrupt politicians, judges, and CEOs!
That's a fairly major power. The question was about a small thing as a power.
Like the ability to know what judges and politicians are corrupt... From reading the newspaper and their court filings, because they already tell everyone that they're corrupt, like all the time. It's not hidden, it's just next to impossible to get people to care about it. Or to get the right people to care about it.
Like, look at Clarence Thomas, the fucker is corrupt as all hell, and since the Republicans don't care, nothing can really be done. Because it's technically not illegal, and Republicans are blocking any form of Ethics reform.
