This is how Thunderwing defeats the Mane Six goes in
Thunderwing: You are no match for Dark Energon.
Twilight Sparkle: Oh, yeah?
Rainbow Dash: You're joking.
Pinkie Pie: Ha!
Thunderwing: Witness the power of Dark Energon.
[Thunderwing fires a blast of Dark Energon at the Mane Six and it hits them and Dark Energon spikes come out of the Mane Six and they fall down in defeat.]
Thunderwing: Yes. Yes! The most powerful Equines in Equestria AND the wielders of the Elements of Harmony ARE MINE! Equestria shall hear Unicron's name AND TREMBLE!
