Equestria is home to a lot of imagination, some of that imagination having spawned the idea of super-powered avengers that take on crime. When ponies think of super heroes, they usually think of selfless acts, justice, and doing what's right. Not the dark side of it, like taking another life, or constantly being hunted by enemies.

But, super heroes are only a mare's tale, right?

A thousand bolts of lightning littering the night sky...

Over a million blood cells carrying a long-forgotten disease...

The time has come for this mare's tale to be tested.
