"Beware my power!" "Me Grimlock STILL beating you up!" "I'll blast you back to the Bronze Age!" "Dino-dodge!" Considering their last interaction in Fall of Cybertron, I can't help but feel like the first Starscream encounter was MADE for Grimlock.
It makes sense, you unlock him just after beating the stage before, so most players would in turn decide to use him to try him out. Best part for me was that each time Grimlock mentioned beating him up, I had used my special so I was just dragging him along the ground as they talked. It was great.
"Even though i'm ALREADY his second-in command,and i'm planning on overthrowing anyway,but still ! A chance to impress someone i despise ! I couldn't resist !"
i don't think that this theme have the official name, but it can be called: "Star's scream", "Scream of the star", "Star's battle cry" or "Battle cry of the star"
