You were the new recruit of the Autobots, only a few knew you on the first day, but you expected that, but the only problem is that you didn't know how to defend yourself from a dangerous Decepticon, so you were escorted to the training room to spar with an Autobot

Once you got there, you saw a yellow, short Autobot

"Oh hi! You must be the new recruit?"

He held a hand out to shake your hand

"I'm Bumblebee, and I think I'm supposed to be your sparing buddy for a while."
