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, Mane Six.
Twilight Sparkle: Oh yes we can.
Rainbow Dash: Crash will stop you and Uka Uka.
Pinkie Pie: Ryan will fight you.
Rarity: We rather have Twilight Akumatized.
Fluttershy: You will stop.
Megatron: Give yourselves to the dark side. It is the only way you can save your friends. Yes, your thoughts betray you. Your feelings for them are strong. Especially for Twilight's... Sister-in-law. So...Twilight has a sister-in-law. Her feelings have now betrayed her, too. If you six will not turn to the dark side, then perhaps she will.
Twilight Sparkle: Never!
[The Mane Six and Megatron battle, ending with Twilight blasting off Megatron's right hand. Megatron falls to the floor, defenceless, as Twilight lowers her horn, Dark Magic at ready, to Megatron's throat. Megatronus walks down, cackling and applausing at the Mane Six's victory]
Megatronus: Good. Your hate has made you powerful. Now, fulfill your destinies and take Megatron's place at my side.
[Twilight looks at her horn and Megatron's severed hand]
Twilight Sparkle: Never. We will never join the dark side.
Rainbow Dash: You have failed.
Pinkie Pie: We are heroes.
Rarity: And Autobots.
Applejack: And Ryan is a Prime.
Fluttershy: Like Optimus, Prima, and Solus Prime before him.
Megatronus: So be it...heroes. If you will not be turned, you will be destroyed.
[Megatronus shoots lightning from his fingers at the Mane Six. The Mane Six fall down in pain as Megatron gets up and walks to his master's side]
Megatronus: Young fools... only now, at the end, do you understand.
[Megatronus shoots lightning at the Mane Six twice]
Megatronus: Your feeble skills are no match for the power of the dark side. [shoots lightning at the Mane Six] You have paid the price for your lacks of vision.
[Megatronus shoots lightning at the Mane Six as they writh on the floor in unbearable pain as Megatron watches]
Twilight Sparkle: Megatron please.
[Megatronus continues to shoot lightning at the Mane Six as they writh in pain. Megatron looks at Megatronus and the Mane Six. Megatronus stops shooting lightning]
Megatronus: Now, Mane Six...you will die.
[Megatronus increases his lightning in intensity and shoots at the Mane Six as they writh in pain. Megatron looks at them and Megatronus and back at them as they scream in pain. Megatron
Megatron: No. NOOOOOO!!
[Megatron grabs Megatronus' hands]
Megatronus: Megatron, what are you doing?!
Megatron: Send my regards to Ryan F-Freeman. A fellow Prime of your love, Solus Prime.
Megatronus: You dare betray me for these Equine weaklings?!
Megatron: Have a nice day!!!!
[Megatron throws Megatronus to a portal]
