If you are given a chance to choose a power what would it be that will you choose? Will you choose to become like superman? Becoming like superman is a good thing but you also get great responsibility they say.
If you get his powers you can hear alot of things, see things beyond the walls(usually wanted by some people) move at great speed good for you if your being late.
Or you can become the flash and travel through time, the good part you see peolple in person and what they did really. Bad thing is that you must affect the future and also yourself coz a sligjt changes in the past will make big changes in the future a ripple effect.
Its like a domino's you kick one then the rest is affected in a way you dont know. Specially if you went in way way back before you ever born. But all of this is just theory in itself since no one were still able to go back to the past.
There were many powers we could think of but all of those have good and bad depends entirely on the person who is using it. My opinion only
Like Solomon, I'll seek for the power to possess the greatest wisdom
