The only super-power that matters... Perfect Reality Manipulation.
Because PRM allows for the control and manipulation of any conceivable Reality, in any conceivable way.
Simply speaking, I could literally do anything within the scope of imagination. Anything.
I could make myself immortal, indestructible, faster than light, and completely invisible to any form of detection.
If I saw a cat stuck in a tree I could tele-port the cat to the ground, tele-port myself to the cat and drag it to the ground, turn the tree into jello and eat it until it fell over and the cat fell out, call down a giant meteor to scare the cat out of the tree, reverse the flow of time until the cat wasn't in the tree and convince it to not climb the tree, or even swap the two so the tree was stuck on the cat... Though that would be messy.
The list is, literally, endless. Anything within any scope of imagination would be mine to control.
Greedy? Oh yeah. But I'm a huge fan of messing around with stuff to see what happens.
I could even create a hundred billion-strong army of half-inch tall, indestructible Raptors that could fly and breath in complete vacuum. How awesome would that be?
