@quintus_knightfall: It might be cool.
Old Arrow use to have reality manipulation, he used it during the RPG where Rina went mental and messed with all the kids and destroyed parts of America, I may have used it one other time but can't remember why.
I found the key to it was checking with others before cracking it out, I would never use it unless it helped the story line or had a overly bad effect on someone. Trick is with over the top powers, was to never abuse them and use that other super power called common sense.
That said I have no powers now and loving it....who wants a hug.
