You, Ben and Rook were now walking to school as.you were talking to your partners.

Rook: as your partners we to stay.together at all costs.

(Y/N): Well mot that i mind you coming with but rook your gonna have to blend in.

Rook: I don't understand.

(Y/N): i mean you can't go around like this. Put his on.

You gave rook an I.D. mask.

Ben: where'd you get an I.D mask?

(Y/N): I brought it with me as a souvenir before i moved. Figured it might come in handy and i was right.

Roo put on the mask as it made him look human.

Rook: How do I look?

(Y/N): You look human. At least you'll fit in.

You and the others went in the school as you got to your locker and grabbed you things only to see Keith.

(Y/N): Keith? What are you doing here?

Keith: Oh didn't you know? I go to this school which means I'm gonna be you new classmate.

(Y/N): And i was hoping to never see your face.

Keith: don't be like that it'll be like old times.

(Y/N): Well i didn't like the old times that you were here.

Keith: Well to bad. Cause I'm gonna have fun with you.

He then walked away as you were now heading to the others as you saw the others.

Jessica: (Y/N) what's wrong?

(Y/N): just ran into Keith. He's now enrolling here as a student.

Kara: Who's Keith?

Jessica: He's (Y/N)'s old bully. Me and him ran into him before.

Babs: wait why didn't you tell us you were bullied?

(Y/N): You didn't ask.

Karen: well anyway we should head to the bus.

(Y/N): why?

Karen: didn't you hear? we're going on a field trip today we're going to a museum.

(Y/N): Oh i guess i didn't get the memo.

You and the other students head to the bus as you all were now going to the museum. As the bus stopped you looked to see a space museum. You went inside to see exhibits of spacerovers, asteroids, and satellites.

(Y/N): amazing, i never seen anything like this.

At a lab we see a man with a jar with purple goo in it.

Man: Peekaboo!

Woman: what are you doing?

Man: oh i did all the usual tests i could think of with no External or internal response. Let's get lunch.

As he and the woman left the chair rotated and hit the jar making it fall and for break freeing the goo as it went through a air vent as a mouse went by and the goo shifted into the mouth as the mouse saw and the goo creature growled and chased it. As for you you saw a shuttle pod.

(Y/N): i always wanted to be like an astronaut so maybe i should go with an alien that knows his stuff.

You went through the Omnitrix and slammed it as you transformed.

(Y/N): Grey Matter!

You crawled into the shuttle as you were now in the control console.

(Y/N): Captain (L/N) reporting to central command. *high pitched voice.* This is central command there are enemy ships on your tail. *normal voice* oh no reinforcements! And their firing lasers! Not to worry i shall fend them off with pur deflector shields. *press a few buttons.* *high pitched voice* captain what is our next move? *scotty voice* we are surrounded by the alien army we must fight. *sees a mouse* Anson fire our blast cannons

You were startled cause a mouse was in the shuttle with you.

(Y/N): Where did you come from? Don't you know, you shouldn't be playing in a museum exhibit?Babs

You saw the mouse move strangely as you walked to the mouse and saw it has purple eyes.

(Y/N): Well i am certain you are no ordinary mouse, I've never seen move like that before.

The mouse became purple goo as it started you as it began to change shape as it looked like you in grey matter form.

(Y/N): *gasps* Fascinating you can copy forms? It's no kidding you look just like me.

You saw it was copying your movement.

(Y/N): What? *you did a dab* You can even copy my moves? *gasps* that is over the line! I worked hard to perfect that pose and you can copy it so perfectly! It's bad enough that I'm in here but if we both get caught I'll get double detention. Why don't you move along?

The creature's eyes turned purple as it became angry and walked towards you.

(Y/N): Or not.

It tackled you as it was trying to fight you as you got out as the creature was after you then it grabbed you and threw you into a closet as a janitor closed the door.

(Y/N): that could have gone better. *gasps* Wait I'm trapped!

You changed back as you ran to the door as you tried to open it as it was locked.

(Y/N): Let me out!

Then the others came and saw the creature as they thought it was you.

Ben: wait why are you grey matter?

Back with you you tried to open the door only as you were trapped.

(Y/N): great I'm trapped and that thing is out there pretending to be me. I hope the others come and find me.

As for the creature it was acting weird as the others were wondering.

Ben: why didn't he changed back?

Kara: yeah he's just being stupid.

As she started to nudge the creature started to copy her as she took noticed.

Kara: hey quit copying me. I'll pound you!

The creature got angry and changed into Kara.

Jessica: Kara calm down.

Ben: Guys

Jessica: *gasps* unless the Omnitrix is showing off a new feature I don't think that's (Y/N). Stay back whatever you are what did you do to our friend?

The creature then shape shifted into Jessica as the others saw.

Babs: we need to go.

The ran as the monster grabbed a panel and threw it As you heard the sound.

(Y/N): That doesn't sound good.

You slammed your watch and transform

(Y/N): four arms plus four? Ok

You burst through the door as you were looking for the monster.

(Y/N): Alright faker i got four i mean six fists with your name on them.

Then you saw Jessica.

(Y/N): Jessica? Jessica there's a shape shifting goo monster running around.

Babs: (Y/N)!

You turned to see the others and another Jessica hiding.

Jessica: That is the shape shifting monster.

(Y/N): Jessica? What are you doing over there.

You turned to see the other Jessica turn as you see it's purple eyes knowing that it is the monster.

(Y/N): you think you can steal the form of my friends and get away with it?

The monster started to growl and then shape shifted into you omni enhanced form as you turned to your friends.

(Y/N): you guys get everyone to safety, I'll take care of handsome over here.

Rook: We're on it.

(Y/N): i always wanted to see who would win in a fight between myself.

They girls changed into their hero suits and got everyone out of the museum as you were fighting the monster as you both were evenly matched as you both were fighting you grabbed hands and looked at each other.

(Y/N): You might know everything I'm gonna do but that ain't no good because i know everything your gonna do! How about that?

The creature started to move strangely as you took notice.

(Y/N): Wait i can't do that.

The monster grabbed you as it threw you into a wall as you saw the monster come at you as you dodged it and tried to punch it as it was stretching out of the way of your punches and grabbed you and threw you to the ground.

(Y/N): Ok so I'm a bit stronger than i thought so it's time to get serious.

You brought your four blue fists together as the produced blue electricity as the monster copied you move but it didn't made any shock energy.

(Y/N): Wait it can't use the shock energy. Oh yeah now we're talking. Bring it on faker!

You charged at it as you sent electrical punches at the creature weakening it a bit but it was still going as the others saw.

Jessica: it's no use there perfect match in strength.

As you started to charge at it you changed back as you saw the creature was still in four arms form.

(Y/N): uh oh.

You ran as the creature saw its reflection on a panel and it freaked out losing control of it's form as it grabbed the panel and threw it as you got to the others.

Kara: now we can't stop it now that it (Y/N)'s strongest alien.

(Y/N): Well i would of stopped it if i wasn't trapped in the storage closet.

Kara: how were we supposed to know where you were?

(Y/N): i can't believe you thought that faker was me.

Then you turned to see the monster smashing things.

Karen: it's smashing things now?

Kara: maybe it's just dumb.

Rook: wait look what it's been doing

They look as they saw the creature looking at its reflection as it freaked out and lost control of it's form and smashed the glass.

Diana: the creature is attacking objects that has it's reflection.

Ben: maybe it just thinks it (Y/N).

Rook: but it sounded like it was in pain and it loses control of it's shape in front of them before it attacks

(Y/N): how we make those mirrors less fragile.

You used your Omnitrix and transformed as you were now Omni Enhanced Diamondhead.

(Y/N): ready for the final round?

The creature turned and saw you as it charged at you as you used a shield made of diamond as it came to you and saw it's reflection and freaked out and tried to punched you as you dodged it.

(Y/N): couldn't take that huh? I'm just getting started.

You made a mirror made of diamond as it freaked out and continued to lose control pf it's shape as it tried to escape but you made more diamond mirrors as it was trapped as it continued to lose control of it's shape as it reverted back to what it was before a little puddle of purple goo.

(Y/N): that's what it was before.

The man and woman came to the puddle.

Man: the specimen escaped.

Ben: what is that?

Man: we don't know but that copying thing was cool.

Woman: must be an accelerated way to reach the top of the local food chain.

(Y/N): wait it trying to eat us?

Man: that's one hypothesis but we won't know for sure without more extensive tests and thanks to you we now know what stimuli this material responses to.

As they left you saw the others.

Babs: that was awesome doing that mirror thing.

Jessica: and besides there's only one you.

You smiled knowing that you are one of a kind and that there's only one you.

Hope you like it because there's more on the next time. Meet the cheetah. Hope you enjoy.
