Normal day in Princess Celestia's throne room! She gets a letter...
it's just the mane 6 again.
Oh! Forgot! She needs to go to Fillydelphia, because the Wonderbolts are performing!
Zoop! Off Celestia goes! 
The announcer begins. The Wonderbolts are performing one of her favourite stunts... And there's a pegasus circling above? Who? Misty fly? Fleetfoot? Rapid fire? It's...
Who is that? It looks different, black with giant wings that casted a huge shadow across the arena. Impressive stunt, he started what could've been a tornado, soaring higher toward the sun...
He started spinning around again as fast as sound. Beams of blinding light shot towards the crowd. The Pegasus came to an abrupt stop, and sharp, dagger like points pushed its way through his feathers. He only sang a high pitched note, and glass fell upon the crowd, but six of the shards were colourful. Magenta, purple, blue, red, pink, and orange, that could only mean one thing.
