Fiction

Find Your Fate... Junior

Desert FlightMegatron uses his Magna-mike to rant at the Autobots for several miles as they approach the Decepticon anti-gravity base. He does so at great length, clearly enjoying the sound of his own voice. Everyone is like "Oh that naughty Megatron, he's using is Manga-mike again!"

(The name is hilarious.)
