I try to come up with useless superpowers all the time! :o)

Actually, true story, I was on the phone with a friend of mine, we each had a copy of the Marvel Role-Playing Game, Ultimate Powers Book. I told him, let's hang up, call back in one hour, randomly generate as many characters as we can in that time and see who has the most useless hero. One hour later, I had made 12 and he had made 7 characters or something like that. The winner was mine: His "origin" was Ghost, so he was a disembodied dead spirit, with a "Psyche" attribute of Feeble meaning he could never physically manifest himself or become visible to others, and his sole power was "Berserk." So, he could see injustice, go into an absolute rage, but never do anything about it. I called him "The Futile Phantom." Good times.
