This is how Opening scene: Bumblebee's promotion goes in Transformers Prime: Friendship is Magic: Beast Hunters: Predacons Rising.
[The film opens on Cybertron]
Optimus Prime: We have endured bitter hardship and countless battles but at long last, our home planet has been restored. We would not be standing on Cybertronian soil were it not for the valiant efforts of both those here and our absent comrades: Major Malfunction, who , and Cliffjumper, who made the ultimate sacrifice. But on this day, at the dawn of a new era, we gather to bestow a special honor one earned by Bumblebee. Through his bravery and devotion to the cause of peace, long before, he rid this universe of the scourge of the Decepticon warmonger. In the company of your fellow Autobots, in the presence of our creator, Primus, the living core of our planet, and by the authority vested in me by the Matrix of Leadership, Bumblebee arise a warrior.
Bulkhead: Warrior, big time!
Smokescreen: You go, Bee.
Wheeljack: Let's get this party started!
[Wheeljack chest bumps Bulkhead]
Smokescreen: Welcome to the club, Bee. Warrior today, and who knows? Prime tomorrow?
Bumblebee: Slow down, Smokey. I'm not sure I'd wish a Prime's responsibility on anyone.
Optimus Prime: I am sorry to interrupt your celebration.
Arcee: Here it comes.
Bulkhead: Primes never party.
Optimus Prime: But I must take my leave of you.
Ultra Magnus: Sir, may I ask why?
Optimus Prime: Though Cybertron is once again able to support life, our planet is currently incapable of generating new lives. Not until I retrieve the wellspring from which all life on Cybertron is born and ultimately returns...The Allspark.
Smokescreen: You mean it isn't here?
Optimus Prime: Nor has it been, Smokescreen...not for thousands of years. As the war for Cybertron reached a tipping point and the Decepticon army appeared to be unstoppable, I opted to safeguard the Allspark from Megatron by covertly sending it to a distant sector of the galaxy. The Matrix of Leadership will enable me to guide us to its present location.
Bumblebee: What are we waiting for? Let's take the warship and bring it back.
Optimus Prime: These remain dangerous times, Bumblebee. We cannot leave Cybertron unsecured not with Starscream and Shockwave unaccounted for.
Ultra Magnus: Not to mention our stray Predacon.
Optimus Prime: Ultra Magnus, you will supervise patrols to find and capture the fugitive Decepticons.
Ultra Magnus: I would be honored.
Optimus Prime: Bulkhead, you will lead there construction effort. Begin by building a landing field to welcome returning refugees. Wheeljack, I will require your extensive experience navigating deep space.
Wheeljack: When do we leave?
Optimus Prime: And Twilight, I will give you the honor of you accompanying me to retrieve the Allspark as my partner.
Twilight Sparkle: Why?
Optimus Prime: Because
