X-ray images: wiring, circuitry, etc. flash on and off as a new and larger being starts to form, changing from dented Megatron to a huge, new creation: Galvatron.
"Behold Galvatron, and these shall be your minions, Scourge, the tracker and his huntsmen the Sweeps, Cyclonus, the warrior and his armada, and this shall be your ship now go destroy the Autobot matrix." Unicron said.
"I will rip open Ultra Magnus and every other Autobot until the matrix has been destroyed, to Cybertron." Galvatron said.
"Destroy the matrix." Unicron said.
"You go far beyond yourself," Shockwave said to Starscream. "Megatron would melt you down into scrap and feed you to a space slug."
Standing across from Shockwave within the main base of operations of Kaon was Starscream. He was decked in a purple cape and steel plated shoulder attachments. "You've no right to speak to the soon-to-be new leader of the Decepticons in that way, Shockwave. I suggest that you mind you manners."
"Need I remind you that at the outset of this war, Megatron placed me in charge of Cybertron while he was away," Shockwave pointed out. "By rights, it is I who should assume leadership of the Decepticons."
"Need I remind you that I am Second-in-Command of the Decepticons, Science Officer Shockwave," Starscream said point blank. "My rank supersedes yours, end of story. Now if you'll excuse, I don't want to be late for my own coronation."
With that Starscream left, and Shockwave muttered to himself, "Coronation my optic."
The former city square of Kaon was wide open and went in all directions. Along the edges stood an assortment of golden monuments of the long dead members of the Cybertronian High Council. At the center, numerous Decepticons, ranging from the recently returned force from Earth to the one who'd never set foot there, were gathered. They were gathered, forcibly for some by the Constructicons, to watch what most considered to be nothing more than a faux pas of ascension to leadership of Starscream. Slipstream, Blizwing, Barricade and Wreckage were among the more vocal. Soundwave and his Minicons remained silent, save for Rumble and Frenzy. It wasn't going to matter now either way, for Starscream appeared atop a high podium overlooking the square. Astrotrain and Thrust were standing to either side of Starscream as the crowd of 'cons looked on in silent resentment. Starscream smirked at his soon-to-be subordinates as Astrotrain approached. In his hands was a gold studded crown decorated with rubies, possibly stolen from Earth some time ago. Starscream sank a knee and waited for the crowning. Astortrain hesitated.
Starscream sensed the hesitation and leered at the Triple Changer. "I'm waiting." he said.
Oh, how Astrotrain wanted to blast the Seeker's head clean off. But instead he reluctantly crowned Starscream. "All hail Starscream, new leader of the Decepticons." he deadpanned.
Starscream rose and leered at Astrotrain again before sauntering up to the edge of the podium. Outstretching one arm, Starscream addressed the masses. "My fellow Decepticons; I am truly humbled to lead our forces on the new journey that awaits us. I swear to you that…"
Before Starscream could continue, a high pitched whine came from the far north of the square. The next thing the Decepticons knew, a squadron of seven unidentified crafts flew overhead and breakneck speeds. Soundwave was able to get a visual of one of the crafts and he could easily identify the Decepticon insignia upon their hulls. Starscream didn't like having his moment interrupted.
"Who disrupts my coronation." Starscream snarled.
"Coronation, Starscream," said the intruder. "Are you serious? So disappointing, to think you'd stoop this low to ensure power."
Something about the intruder struck Starscream; something familiar. "I'll ask you again; who are you?"
The intruder didn't remove his glare from Starscream even as he climbed step by step until they were face to face, a couple steps separating them. "You should've realized by now, Starscream that even in death, there is no command greater than mine."
Starscream's optics pulsated bright red and then the realization struck. "Megatron is that you?"
"Here's a hint." Galvatron said.
Galvatron transforms into cannon, FIRING A HUGE BURST ON STARSCREAM
as BLAST hits him. For a moment, he retains his shape then piece by piece, he falls apart.
Only a pair of feet remain on the floor.
He transforms back to robot mode and confronts other Decepticons boastfully.
"Will anyone else attempt to fill his shoes?" Galvatron said.
"What did he say his name was?" Rumble said.
"Galvatron." Galvatron said.
