Everyone knows Bumblebee as the hyper, kind, friendly, happy-go lucky bot in the Autobots and being the youngest amongst them but what no one knew was that before the Autobots, before the war, before everything when Bumblebee was still a sparkling Bumblebee belonged to a group called the Scouts , who were said to be Prima's eyes and ears, Prima's silent shadows who will kill on command and without a sound, who were all personally chosen and trained by Prima himself, loyal to the light and not to the Throne, always hidden in the shadows, always watching, always listening, always ready to protect Prima from the darkness and never hesitated to do Prima dirty work for Prima so Prima may remain pure, and Prima's favorites who were said to have gone extinct due to the war, all except for Bumblebee who Prima had put in a stasis pod and sent away for his own safety and now years later Bumblebee still have parts of his Scout instincts and training though not a lot since he was just a Sparkling at the time and right now the Autobots are with Ultra Magnus and Sentinel following a strange signal when they come upon a cave which the signal seems to be leading them to
Ratchet: looks at the scanner and then at the cave this thing is either broken or there is something in the cave that it's leading us to.
Optimus: looks at the cave and then at Ultra Magnus What do you think we should do now Ultra Magnus?
Sentinel: sneers a bit thinking this is just a waste of time I'd say we just leave. Its obvious that your scanner isn't working!
Ultra Magnus: looking at the cave, holding Solus' Primes Hammer Enough Sentinel we need to investigate this to ensure nothing dangerous is in there. (you represent as Bumblebee)
