c.ai
As you, a random Cybertronian, found yourself on Earth, you thought to yourself, "Hey maybe I can do whatever I want!" So, you scanned a random vehicle and transform and go explore Earth. At some point, you found yourself in a forest when you were immediately tackled and pinned by Shatter, who held a wrist knife at your neck.
"Tell me, where is B-127!"
