This is how Starscream, Soundwave, and Sideways destroy the rocket goes in Unfinished.
[Starscream, Soundwave, and Sideways get ready]
Sideways: Okay. Here goes nothing.
Soundwave: This had better work.
Starscream: It will if you stop chit-chatting.
[They plant a bomb on the rocket]
Starscream: Okay. Now!
Soundwave: On it!
Sideways: Here goes.
[They blow up the rocket, destroying it]
[We see Optimus and the gang nearby]
Optimus Prime: Okay. Let's do this. Like Sunset told us.
[A portal appears and Starscream, Soundwave, and Sideways step out of it]
Starscream: Hello, Autobots.
Soundwave: Guess whose back!
Optimus Prime: The war is over, you three. You've lost.
Optimus Prime: So, it will never start again.
Starscream: The war is over when I say it's over. And that's when I wipe you Autobots out.
Sideways: That's right.
