The Overlord has returned/Creating the Mean Six out of pure darkness

Here is how the Overlord returns in The Overlord Unleashed.

But further in the darkness, the Overlord awakens.

The Overlord: The time has come for my revenge against the Ninjas of Ninjago starting in this realm.

So, he gathered General Kozu, General Cryptor, Clouse, Acronix, Krux, Pythor P. Chumsworth, and the Dark Tribe Leaders of the Scorpion, Bat and Spider Tribes, Scorm, Braptor and Spinlyn.

The Overlord: It's time we make ready for our revenge against our common enemies, the Ninjas of Ninjago!

General Kozu: Yes, Overlord.

General Cryptor: We will wait at your command.

The Overlord: Did you, Acronix and Krux gathered enough items and images, Pythor?

Pythor P. Chumsworth: Yes, my Dark Lordship.

Acronix: Every image of the Princess of Friendship and her five little friends.

Krux: Plus, the sample of every DNA in hair from their mane.

The Overlord: Excellent. Now, to begin step two before I can steal their alicorn magic.

Spinlyn: But why on earth would you want alicorn magic anyway?

Scorm: Especially when you are more powerful ever since you returned twice in Ninjago.

The Overlord: Why would I want alicorn magic? Because their magic are more powerful than ever and it was the most rarest and purest of all magic the entire universe would experience.

Pythor P. Chumsworth: We're ready to begin, Your Lordship.

The Overlord: Good. Now, let there be life for a dark power.

At last, the Overlord created the Mean Six out of pure darkness and opposites of the Elements of Harmony Twilight Sparkle and her friends possess.

The Overlord: Welcome, Mean Six.

Evil Twilight Sparkle: Where are we?

Evil Applejack: Why in tarnation are we here!?

Evil Fluttershy: This is ridiculous!

Evil Pinkie Pie: Well, I'm not laughing!

Evil Rarity: How revolting for ponies like us!

Evil Rainbow Dash: Who do you think you are!?

The Overlord: I go by many names, but you can call me Overlord! I have plans for the six of you.

So, the Overlord make ready to begin his dark purpose for Equestria.
