Pretty sure x-ray vision, as originally envisioned, wouldn't allow Superman to see that Margot Kidder's panties were pink. But if it did work that way...
Flying. Slower than instantaneous transportation but better views. However, one of my all time favorites is psychokinesis.
See I went teleportation, but I thinknflying is cooler. Like you can't fly through solid objects, but you CAN wear a cape. I was honestly pretty torn.
Definitely time travel. You could guarantee generations of riches, gather medical breakthroughs, deter wars, or write material for Elvis or the Beetles. When ever I think of time travel, the book “A Hitchhiker’s Guide to the Universe” comes to mind.
I've given this a lot of thought over many years of being a nerd, and I've decided that if I had a power, I would want it to be the ability to conjure a pineapple wherever and whenever I wanted. Not only would it make me a very popular support hero, able to dispense emergency hydration and vitamins at will- it would also make me pretty unbeatable in a fight. My arch nemesis: "So, Pineapple Girl.. You think you can stop my plan to take over the- urk!" Bystander: "Wait, what happened?" Bystander 2: "Did.. Did he just die?" Bystander 3: "Holy hell, his brain is leaking out his ears! And... Pineapple juice?" Me: *whistles innocently* ... I did say wherever I wanted, didn't I? --^@
I can't help but think of the scene in X Men Apocalypse where Magneto kills a bunch of people with a metal coin. But with pineapples. And it's hilarious.
