Saturday cute: How to Become Super

Huzzah Nightcrawler! :D Hottest X-man ever, though he's got a few years to go in that particular picture xD

What about the classic "travel to a planet where people lack the abilities your people are born with?"

Or "join an intergalactic peace-keeping/law-enforcement organization."

Getting struck by lightning in such a way that it causes the contents of a shelf full of random chemicals to spill on you also works as well as or better than many on this list (i.e. it happened twice, while many of the scenarios described in this comic were unique events.)
