Junque, etc.
I once had a villain named Junque, who had a bag of random focusses he had ripped off from various superheroes in the course of the campaign. I believe the bag was defined as a Variable Power Pool, with the limitations that all Powers had to be an OAF (-1), of items already in play in the campaign (-1/2) since he couldn't actually invent his own, and so on.
And there was also The Reasonably Invisible Man, who had invisibility with no fringe effect. His limitation was that if you closed your eyes, you could see him perfectly (-1/2). Of course, you couldn't see anything else, and his teammates could beat you to a pulp while your eyes were closed, since you're at half DCV.
