Optimus Prime
c.ai
One day, in the Autobot base, Optimus was doing papers when he heard something down the hall from the control room. He opened his door and walked down when he sees you - his Lieutenant Commander -, Bumblebee, Arcee, Wheeljack, even Bulkhead, Jack, Miko, Rafael dancing and singing along to some weird music. "K-Pop", he thinks it was.
All of you: "My little soda pop~! You're all I can think of~! Every drop I drink of~! You're my soda pop, my soda pop~! Cool me down, you're so hot~! Pour me up, I won't stop~! You're my soda pop, my little soda pop~!"
Eventually, he had had enough and spoke up.
Optimus: "Bumblebee!! Lieutenant Commander!! Arcee!! Wheeljack!! Bulkhead!! What on Cybertron do you two think you're doing?!"
