This is how Thunderwing betrays Queen Chrysalis goes in Transformers Prime: Attack of the Changelings and Thunderwing.
Thunderwing: Finally! I am complete!
Queen Chrysalis: You owe your life to me, Thunderwing. You will call me master!
Thunderwing: I am the envoy of Unicron the Destroyer. Unicron, who summoned me across the vastness of space. Unicron is my one and true master! You, you are nothing.
Queen Chrysalis: WHAT?! WE HAD A DEAL! I GAVE YOU BACK YOUR FREEDOM!
Thunderwing: Consider this a show of gratitude!
Starlight Glimmer: So you have magic~
And it's not that great~
But when it found you~
Trixie: You know it was fate~
And it might seem scary now~
But it can be wonderful too~
Thorax: So how about we embrace the magic~
And make the magic part of you?~
You take a little dash of magic and you let it ignite~
Mix things up a little bit~
Discord: And it might start to go right~
In just five seconds flat~
How the story has changed~
All cause now you've embraced the magic~
And it just got better in every way~
Starlight Glimmer: I say embrace the magic~
No more holding back, just let it out~
If you can take the magic~
And learn a little more what it can do~
Once the magic is part of you~
Trixie: What's standing in your way~
That you can't move today?~
Thunderwing: Equestria shall hear Unicron's name AND TREMBLE!
