Chapter 1
It's been 3 years since the battle of San Fransokyo. The government had witnessed the Big Hero 6 eliminate the decepticon invaders. Now the remaining ones are scattered across the globe. After they graduated, the government began working in collaboration with the team to form the anti-decepticon group now known as N.E.S.T. Baymax had gained the ability to change to the size of the Decepticons, along with the rest of the team, giving them a crucial edge in battle. The group was in Shanghai, alongside military soldiers.
Soldier: Woah woah. Hey. I got a thermal ripple from that excavator.
Soldier: Alright. Eyes front. Keep it tight.
Fred and Honey Lemon walked up. The excavator suddenly sprung to life, and the scoop split into two hands as a face opened up from the center. The treadmills transformed into two wheels that cycled over and under the head. This was known as Demolisher. It started wheeling away causing destruction across the path.
Soldier: Second target on the move! GoGo! It's coming your way!
A silver Nissan drove another direction. GoGo Tomago started speeding after it with her wheels. She threw a disc at it, and it bounced off. The car broke apart into a robot named Sideways, jumping through a building, followed by GoGo. He shifted to a car then curved a corner that GoGo missed, causing her to hit the wall.
Soldier: Bring in Wasabi!
Wasabi came in on a motorcycle. He drove to Sideways, then jumped off his motorcycle, over Sideways, then plunged his plasma blade through the hood, and Sideways' momentum drove him right through the blade, slicing him in half.
Wasabi: Damn. I'm good.
Demolisher was riding through the streets of Shanghai, crushing everything in his path. In the sky, a transport ship was prepared to drop it's cargo, Hiro and Baymax. They dropped out as Baymax shifted to his Transformer mode, flying after Demolisher.
Baymax: Strike team Alpha. I'm in pursuit.
They flew along the rode as Demolisher crashed through. Baymax grabbed onto his side, then aimed his rocket fist down at the bottom wheel.
Baymax: Pull over!
He fired the rocket fist, knocking Demolisher's wheel out of place, and sending him crashing to the floor. Everyone surrounded his destroyed body.
GoGo: Punk ass Decepticon.
Baymax: Any last words?
Demolisher: Thi-i-i-i-s i-i-i-s not your p-l-l-l-a-a-a-a-n-n-n-et to rule. S-S-S-S-Steven shall r-r-r-r-r-r-i-i-i-i-se again.
Everyone looked at each other in fear.
Baymax: Not today.
Baymax pulled out an ion cannon and blew out Demolisher's eye.
A few days later, the group was at a San Diego military base, in a video conference with General Morrshower.
Baymax: General. Our forces have encountered six Decepticon incursions, each on a different continent. They're looking of something.
Fred: Last night came with a warning.
Baymax played it back.
Playback: S-S-S-S-Steven shall r-r-r-r-r-r-i-i-i-i-se again.
Morrshower: Steven. That would be...
Baymax: The original leader of the San Fransokyo attack, but was killed.
Morrshower: Was that who that was?
Baymax: The Decepticons may be looking for an artifact that can revive Steven, but the only known artifact capable of such was the Allspark, which was the very thing used to destroy him, and was lost itself.
Morrshower: With the only shard being held in a Top Secret security base in New Jersey.
In space, a Decepticon named Soundwave was hacking into a satellite to listen on the conversation.
...shard being held in a Top Secret security base in New Jersey.
Soundwave: Ravage. Retrieve the shard.
A meteor launched out of Soundwave, and it hit the ground near the secure base in New Jersey. It transformed into a robot tiger named Ravage. It jumped into the base, running through the perimeter fence and through the base.
In the conference room...
Morrshower: Under the best protection the US can offer.
Ravage had made it to a pipe, spitting small metal marbles into it. They fell through the AC in the room the shard was held in, then turned into small crab bots, that all combined into an extremely thin robot that started cutting through the shard container, letting out an alarm. A group of soldiers were inside the facility seconds later, finding the Allspark shard gone. The thin bot cut through one of them, escaping the room with the shard. Ravage fired his back weapons at the soldier, allowing the machine to escape.
Morrshower: And Steven's body is seven miles into the Laurentian Abyss in the middle of the ocean.
Soundwave heard Morrshower say this, sending the newly arrived Ravage back down near the ocean.
Honey Lemon: How do we know it's safe?
Hiro felt something on his suit, and pulled it out, finding a shard of the Allspark stuck on his suit.
Hiro: You guys. I think a sliver of the cube got stuck on my suit.
As he grabbed the sliver, an energy surge hit his brain, imprinting a signal into it as he dropped the sliver. He grabbed his head in pain as different symbols appeared in his mind before he blacked out.
Honey Lemon: We're gonna have to pick this up later, General.
The video hung up.
In the ocean, a massive freight boat was carrying different construction vehicles in the middle of the ocean. Ravage landed in the boats, and the construction shifted into Scrapmetal, Long Haul, Rampage, and Mixmaster. They jumped off the boat with Ravage into the Laurentian Abyss. When they reached the bottom, finding Steven entombed by barnacles, saltwater damage, sand, and algae. Ravage opened his chest and a small crab bot with large eyes popped out, named Scalpel.
Scalpel: Need parts! Kill ze little one!
Long Haul and Mixmaster crushed and smashed Scrapmetal, and his parts began to upgrade and change Steven's body. Scalpel got onto his chest and prepared the shard.
Scalpel: This shard make energon!
He plunged it into the chest, and Steven powered to life. He now had large treads for feet, a cannon with two blades for his right arm, massive shoulder spikes and his hair was spiked upwards slightly. He launched through the water, crashing into a submarine, then flying into space, changing into a flying tank. He reached the planet cybertron, changing to his robot form, backflipping then landing on the floor.
Steven: Starscream, I'm home.
Starscream: Lord Steven. I-I was so relieved to hear of your revival.
Starscream was kneeling to Steven, who scratched the underside of Starscream's chin.
Steven: You left me to die on that pathetic insect planet.
Starscream: Only to spawn a new army. After all, in your absence, someone had to take command.
Steven kicked Starscream in the face, then pinned him to the wall.
Steven: How disappointing. Even in death, there is no command but mine.
Starscream's body opened the pods where new Decepticons were being hatched.
Starscream: Hatchlings! Careful, fragile!
Megatron flew in behind Steven, having his original body.
Megatron: My master, I've failed you. The Allspark is gone. Without it, our race will perish.
Steven: You have much to learn. The Allspark's power and knowledge can never be destroyed. It can only find a new vessel. The human child that killed me has become the new vessel.
Megatron: Then let me strip the very flesh from his body.
Steven: And you will. In time. Steven Universe...has returned.
