We see (Y/N) as he is in the base under sweet justice as he was going through his aliens.

You slammed the Omnitrix and started to transform

There was a loud sound.

Barry: sounds like the pipes settling.

Jessica: it came from the base I'll check it out.

She went to the base as she went down and saw you in you new alien form.

(Y/N): Who's the man? Not you cause your an alien. Who's the alien?

You saw Jessica as you quickly hid but you were still seen.

Jessica: (Y/N) what are you doing?

(Y/N): just looking through some aliens pretty cool huh?

Jessica: are you crazy? You could if been caught.

(Y/N): Hey, but I didn't. Time to give this new guy a test drive. I bet he's really strong.

You went to Kara's weights and tried to pick up the heaviest weights.

(Y/N): *straining* maybe stronger than four arms. Maybe I'll call him Big Boy or Brawno.

You picked up the weightand began to fall a bit.

(Y/N): maybe not as strong as i thought.

You were gonna land on Jessica but she hit you on the back as you now split into two and became small.

Jessica: Oh no, i split you in.

She sees you and your duplicate.

Jessica: two?

(Y/N) 1: whoa this is cool.

The second you grabbed the weights and you picked it up easily than before.

Jessica: (Y/N) your halves are now twice as strong now.

Then you jumped as you made a loud sound.

(Y/N) 2: oh and twice as heavy by the looks of it.

(Y/N) 1: there's something i don't get. Are you me or am i me?

(Y/N) 2: I think we're both us.

(Y/N) 1: neat.

But a shelf fell and landed on you and you double as it crushed you as you lifted it up and threw it as you were now in 4. The rest of the girls and ben and Rook came and saw you as you and your doubles were running around Jessica as you and you other selves were clapping.

Jessica: meet (Y/N)'s new alien or aliens.

Ben: wow it's kinda like ditto.

Jessica: (Y/N) can you at least control your slapbacks.

(Y/N) 1: Slapback?

Jessica: you know you duplicate whenever you get slapped in the back.

(Y/N) 1: maybe we should vote on it. All oppose?

(Y/N) 1 2 and 3: I! 

(Y/N) 1: And those for slapback?

Jessica: I.

Babs: I!

Zee: I.

Diana: I.

Karen: I.

Ben: I.

Rook: i think it's suiting.

Kara: Whatev.

(Y/N) 4: Sound's good to me.

(Y/N) 1: Traitor!

You tackled your you as you began to fight only for you and your to come together making you a bit big.

Jessica: seems like coming in contact with your doubles make you go big.

Your other duplicates came to you as you became whole again and changed back.

(Y/N): ok i got to admit slapback is a good name.

Jessica: Yeah, and next time you wanna try out new aliens maybe you should do it somewhere else other than in the base.

(Y/N): Yeah, seems fair to me.

Babs: i know let's head to the junkyard it's got more space for you and your alien forms.

(Y/N): yeah seems good to me.

You all were now at the junkyard as you were now going through aliens.

(Y/N): Lets see who we got today.

You checked your Omnitrix and saw a familiar one and slammed it as you began to transform

https://www.youtube.com/watch?v=jiv8klMbJxw

(Y/N): Swampfire!

Babs: who is that!?

(Y/N) An alien that me and my cuz call swampfire.

Diana: demonstrate it's powers.

You lifted your hand as vines started to grow. Then you saw a old dresser and threw a fireball at it burning it.

Diana: in this form you have the ability to control plants and blast fire.

(Y/N): Yeah and i think this Omnitrix might have some additional features.

You then slammed you badge but rather than changing back your form began to change

https://www.youtube.com/watch?v=haLsR769FAA

(Y/N): Ultimate Swampfire!

Ben: you can go ultimate?

(Y/N): Yeah looks like my Omnitrix has some special features. So there's a time to go hero, a time to go omni enhanced, and a time to go ultimate.

Kara: in English please.

(Y/N): means that not only i can turn into aliens. I can evolve them into their ultimate form. Now let's see who else is next.

You slammed the badge and you changed again as your legs became a snake tail with a blaxk tip on it, as your body grew scales as your face became a cobra's face and your eyes became green, as you had on green and black bracelets and a green and black tunic with a green and white belt with the Omnitrix symbol on it, as your tunic and belt had whit spikes that look like a snake's fangs.

(Y/N): Thisssss isssss interessssting.

Babs: I've never seen that one before what do you call that one.

(Y/N): Thissss guy, i think I'll call him Ssssnakepit.

Kara: Snakepit? Seriously?

(Y/N): whatever it'ssss a great name.

You started to slither to a car and started to wrap yourself around it. You started to squeeze it causing the car to get crushed as you then slithered to the others. And you changed again as you are now a being made of crystal like diamondhead but expect that you are now made of red crystal and you had on a black, and green suit as it had green stripes on the waist as you had two Crystal spikes on your back as there was red crystal on your knees as you had green eyes as the badge was on your chest

Ben: you look like diamondhead, but red.

(Y/N): I think I'll call him Krimzon.

Jessica: what can this one do?

You looked at a car and shot red shards at it and soon the crystals started to turn yellow and then they blew up the car.

(Y/N): Wow i got explosive shards. I wonder.

You took the Crystals of your back and they form into a boomerang as you threw it at a dented sign as it bounced off and you caught it an put the crystals back on your back as you changed back.

Babs: so how other aliens do you have.

(Y/N/): don't know but I'm learning as i go and i might have more aliens.

Diana: and I'm sure your aliens will be great in battle.

You smiled at Diana as you looked at you Omnitrix as you wonder what other secrets it has in store for ya.

What other secrets dose the reader's Omnitrix has? Well find out next time. As for next time Field trip and a shape shifting goo monster. Hope you guys like this chapter and hope you like cool aliens cause there is more of them coming.
