If I could have any superpower, I would choose the power of flight or teleportation because either superpower would make traveling easier and cheaper. After all, I enjoy traveling.
I agree, I would so choose flying as a superpower. It would be such an experience to soar over mountaintops, zoom down to enjoy the view of waterfalls or gorgeous valleys up close. Definitely flying. XRay vision would be terrifying, there are things I never need to see.
