Episode:The Shadow Champion
 
Tralier: Nightmare moon:I’ve always looked up at the stars on that lonely planet, the stars were what all that were there, on the moon. In the past the mane six defeated what created me and what was the conseqeunce of it, the Tantinbus, the Nightmare Force. Minutes after the Tantinbus’s defeat, the Taninbus sent a dying message across the night sky….
 
And the shadows, have answered
 
Diacroga was an enemy of equeastria long before the Super Pony Squad or the mane six was even thought of. He was banished from equeastria by the princesses and a dragon king named King Lizcon, and is now the enemy of Nightmare moon ever since she was brought to good by the Squad.
 
Diacroga created the shadow force with the power of his dark, shadowy soul and sorcery. He used the Tantinbus as his means of power and a pet, but ever since the mane six have defeated 2 of his creations, he became furious, so he started corrupting any being that came in his way. He twisted and shaped them into Shadowlings. And will soon take revenge on equeastria and will destroy the so called Super Pony Squad.
