A/N: I'm going to change the story a bit from the original TV show Canon timeline.. I know what you're thinking I'm all right reincarnated into Steven Universe Dimension as Steven but a bit different has the power to transform into the gundams and summon it's weapons..
At the end of Universal Century year 0093...
Almost reaching a climax of Char's rebellion.. Axis was almost supposed to be dropped into the Earth's atmosphere.
However only for the sacrifice for the psychoframe to be activated for both the ace pilots Amuro Ray and Char Aznable..
The psychoframe started to activate it Axis was started to pulling away from the Earth..
However the souls of Amuro Ray and Char Aznable we're about to be reincarnated into a new world.
Steven Universe Dimension..
Greg and Rose Quartz we're ready to have a baby.
However a few years passed by the moment Greg had the baby known as Amuro Ray also known as Amuro Universe..
You might be wondering if this might actually be more a bit of the original but no... The events will happen similar, but differently..
Amuro Universe was a bit older and was at High School, and also had some money as well from part-time jobs.
Also he was able to getting a driver license and the car with some of the money he was able to get.
But sometimes he likes to go to the gem Temple also the house.
Amuro Universe was making his way back to his original house at Beach City.
Amuro Universe smiling at his hometown driving his car and parked down the beach house.
Amuro in mind: (in a while since I was reincarnated into this world or alternate universe.. feels so different.. my mother was alien and my father was a human.. I'm some type of hybrid human gem.. it feel so peaceful on my computer to Universal Central at least I can finally have some peace..)
Amuro gotten out of the car and heading to words the crystal gem Temple and opened the door.
Amuro: hey guys it's been a while..
Amuro is suddenly attacked by a Centipeetle. It roars at him and he screams. A whip then wraps around it, revealing to be Amethyst's.
Amethyst: Sup, Amuro? *yanks the Centipeetle off of Amuro.*
Pearl can be seen fighting off Centipeetles on the Warp Pad, and Garnet is fighting in the kitchen.
Amuro: care to tell me, what the world are those things supposed to be..?
Pearl: *groans and lifts up a Centipeetle* Ugh! Sorry, Amuro. We'll get these Centipeetles out of your room. We think they were trying to get into the temple.
Amuro: interesting.. I'm guessing that these mutated insects aren't your typical type of bugs..
The Centipeetle that Pearl is holding spits acid onto the floor, dissolving it into a hole, which Amuro and Pearl look in disgust.
Amuro: okay I have to be more careful while they spit acid..
Amethyst: *poofs a Centipeetle and picks her nose* Um, you guys? These things don't have gems.
Garnet: That means there must be a mother somewhere nearby.
A Centipeetle sneaks up from beside Garnet, Amuro got off the pistol and shot Centipeetle for it to go proof.
Garnet: I'm rather pressed for you to defend yourself..
Amuro: let's just saying I've learned how to do self-defense..
Pearl: but still you need to learn how to control your Gem powers..
Amuro: I know that you don't have to tell me twice.. *notices a Centipeetle raiding his fridge* Hey! Get out of there!
Amuro try shooting down Centipeetle with is pistol only for it to dodge and spit acid at the pistol only for it to be dissolved in half.
Amuro: well there goes my only weapon..
Garnet punches and poofs it. Amuro then notices that the fridge is full of Cookie Cats.
Amuro: No way. I-it can't be! Wha-where did you get these?!
Pearl *closes the fridge* Well, we heard that, too, and since they're your favorite...
Amethyst: We went out and stole a bunch.
Pearl: *grunts at Amethyst* I went back and paid for them.
Garnet: The whole thing was my idea. *retracts her gauntlets back to her gems*
Amuro facepalmed at the idea for the Crystal gems to do something idiotic like that.
Pearl: so how exactly was your day in high school..
Amuro: it was pretty good to be honest.. well let's just say I've been doing good also joined a robotics club as well.
Pearl: wow seems to really do have a good day..
Garnet: I agree that you also joined the robotics club must mean you've been doing great!
Amuro: well of course it's my grades have doing great..
Amethyst: well isn't that good for someone like yourself.
Amuro: well I do need something to eat saying that I could have this my favorite ice cream sandwich for a long time.. *bites into it* Oh, so good! (Steven's gem begins to glow.) you tasted just like the same.. (Amuro's gem begins to glow.)
The other Crystal Gem's noticed Amuro's gem was glowing.
Amethyst: Uh, Amuro...
Amuro: Wha-? *lifts his shirt* My gem!
Amethyst: Quick, try and summon your weapon!
Amuro: okay but this is the first time for my power to be activated like this..
Pearl: please try to remain calm, relax your mind!
Amuro listens to Pearl's advice calming and relaxing his mind for his Gem weapons to reveal RX-78-2 Gundam's Shield and Beam Rifle The Gems collectively gasp.
Pearl: *amazed* Steven, it's a shield!
Amethyst: but why does it also have a gun with it..?
Garnet: well to be honest you must be his own way of someone in his own weapons after all he is a gem hybrid..
Pearl: I have to admit this is rather amazing..
Amuro tried to grab the weapons only for it to fade away back into his gem in his chest.
Amuro: did it work by eating my favorite ice cream only for it to summon my weapon..
Pearl: *picks up the wrapper on the floor* What's in these things?
The house begins to rumbles. Silhouettes of Centipeetles can be seen outside the window.
Amuro: What the heck was that?
The Crystal gems run out of the house and see a Centipeetle, biggest of all, crawling up the temple.
Garnet: It's the Mother! *leaps towards it*
Pearl: Stay in the house, Steven!
Amuro: let me help as well!
Amuro remembered Pearl's advice to calm down and relax his mind, it took some time for him to summon the shield and the beam rifle.
Amuro determine: let's do it!
Amuro rushed directly towards mother Centipeetle, mother Centipeetle spitting out acids directly at them, Amuro was able to block the attack with a shield.
Amethyst: good job for you to be able to use the shield, and let's see what that gun of yours can do.
Amuro: don't worry I got this for you!
Amuro using his new type of abilities aimed his beam rifle directly at the mother Centipeetle.
Amuro: take this!
Amuro was able to fire his beam rifle directly at the mother Centipeetle directly at its stomach stomach for that corrupted monster centipede to be proof leaving its gem rolling towards only for Garnet bubbles it away.
Pearl: you really did a good job!
Amuro: well some really much but it was you that helped me..
Amethyst: see now you're able to learn how to use your weapons.
Garnet: but still means you have a long way to go with your powers to be developed..
Amuro: yes I really do have a long way to go..
