I'd either have to go with mind reading or maybe the power to control paper (like from the movie read or die). If you think its a lame power then imagine this; flying through new york on a giant paper airplane.
telekinesis. it is quite simply the most useful power ever. you could do anything... fly, essentially have superstrength(being able to pick up anything), and so much more. it is incredible!!!!!
personally, id like to have advanced eyes. like being able to notice everything to the smallest detail at once. id be able counter attack at the same time as the attack! YAY
