Discord had a secret.

A secret so super-secrety-ultra-sequecy-secretee-secret-classified-secret secret, that not even the Princesses, not the Elements of Harmony, not even Fluttershy knew of it.

His brother.

Chaos ensues as said sibling pays Equestria a tiny visit, intent on questioning his brother. Nothing will stand in his way. Not the Princesses, not the Elements of Harmony, and certainly not the pony who reformed his brother.

Then again, he is unpredictable, like Discord. There will be explosions, wacky adventures, crazed puns and fourth-wall breakers where the two siblings wreak chaotic havoc across Canterlot and Ponyville.

Oh! Don't forget the Pinkie Pie-level parties and craziness!

T for language. "And Violen--"

I said shut up Disarray. Don't make me unleash the Author Pen thingy on you.
