The Mane Six vs Megatron/Megatronus tortures the Mane Six

This is how The Mane Six vs Megatron and Megatronus tortures the Mane Six goes in My Little Pony: Megatronus' Revenge

Megatron: You cannot hide forever, Twilight.

Twilight Sparkle: Yes, I can.

Thunderwing: Give yourself to Unicron's side. It is the only way you can save your friends. Yes, your thoughts betray you. Your feelings for them are strong. Especially for your... Sister-in-law. So...you have a sister-in-law. Your feelings have now betrayed her, too. If you will not turn to Unicron's side, then perhaps she will.

Twilight Sparkle: Never!

[Twilight and Thunderwing battle, ending with Twilight blasting off Thunderwing's right hand]

Unicron: Good. Your hate has made you powerful. Now, fulfill your destiny and take Thunderwing's place at my side.

Princess Celestia: You can't make her.

Princess Luna: She won't do it.

Princess Cadance: And never will.

[Twilight looks at her horn, Dark Magic at ready, and Thunderwing's severed hand]

Twilight Sparkle: Never. I'll never turn to your side. You've failed, Lord of Chaos. I am a Princess.

Unicron: So be it...Princess. If you will not be turned, you will be destroyed.

[Unicron shoots lightning from his hands at Twilight. Twilight falls down in pain as Thunderwing gets up and walks to his master's side]

Unicron: Young fool... only now, at the end, do you understand.

[Unicron shoots lightning at Twilight twice]

<p style="font-weight:normal;font-size:14px;">Unicron: Your feeble skills are no match for the power of chaos. You have paid the price for your lack of vision.

<p style="font-weight:normal;font-size:14px;">[Unicron shoots lightning at Twilight as she writhes on the floor in unbearable pain as Thunderwing watches and Princess Celestia, Princess Luna, and Princess Cadence watch in horror]

<p style="font-weight:normal;font-size:14px;">Unicron: Now, Princess Twilight...you will die.

<p style="font-weight:normal;font-size:14px;">[Unicron increases his lightning in intensity and shoots at Twilight as she writhes in pain.]
