The Cutie Mark Crusaders have been known for getting into trouble from time to time.
They haven't exactly been known for causing massive explosions.
Until recently, anyway.

Upon accidentally cracking open a fallen meteorite in the Everfree Forest, Sweetie Belle, Scootaloo, and Apple Bloom discover that they have all gained powers far beyond that of mortal equines. Which is pretty cool, until they discover that they have very little control over them.
Although, what else does one do when gaining superpowers but to dress up like superheroes?
