Scene: the fallen reveals himself
With the last Prime dead, the Fallen commanded the Decepticons to infiltrate Earth. Hacking into the planet's satellite relay systems, Megatron sent a prerecorded message across every variety of human communication media devices. You are not alone in this universe… hand over this boy…
Megatron swiftly located his Master, rendezvousing with the Fallen shortly after he, and a group of newly arrived Decepticon, destroyed an aircraft carrier vessel in the Atlantic Ocean.
"My master." Megatron bowed as he Fallen looked upon him.
"Rise my apprentice." The Fallen's ominous voice capturing his menacing power.
But Megatron was not intimidated. In fact for the first time, he felt no intimidation from his masochistic leader.
"Master, there is something that has been troubling me." Megatron stroked his chin as he spoke. "Well, if Optimus Prime was the only one that had any hope in defeating you, and I just killed him, then technically, that makes me the most powerful doesn't it?"
"Your point being Megatron?"
"No no. No point. Just remember that when my birthday comes around."
