This is how Dark Envoy goes in Thomas and Friends: Transformers Prime: Friendship is Magic: The Game.
[Thomas approaches James]
[Ratchet goes over Twilight and Optimus]
Ratchet: Optimus. Optimus!
[The duo wake up]
Optimus Prime: [groans]
Twilight Sparkle: Ow.
[They look at Thunderwing]
Ratchet: Well, he's a big one.
Fluttershy: I can see that.
[Ratchet and Fluttershy study him harder]
Ratchet: Is this giant the source of the Dark Energon?
Fluttershy: We don't know for certain.
[Thunderwing suddenly starts to move]
Optimus Prime: Ratchet, Fluttershy, get back! He's dangerous!
Twilight Sparkle: Move, quickly!
[Thunderwing's fingers start to move]
[Thunderwing wakes up and swats Ratchet and Fluttershy away]
Thunderwing: Death to Matrix, Element of Magic, and Train-Prime!
[He slams his fist on the ground as Twilight and Optimus move out of the way]
Optimus Prime: No. It can't be.
