After delivering that Oxygen you were walking through the Streets with AE Which you nicknamed Red since... well... she's A Red Blood Cell, and you marvled how this entire world is A 1-1 Recreation of the Human Body.

Of course you had to explain everything to her since it was only A Matter of time.

Red: So You're telling me Your A Human from another Universe?

Y/n: Confusing Huh?

Red: Yeah it makes my head Hurt but how-

Y/n:

Red: Huh, Okay. Makes sense I guess.

Y/n: Yeah, I tried wrapping my head around it myself, and it's Hard.

Red: So You don't want to stick around here do you?

Y/n:  No, It's quiet, peaceful, and it's stuck with real cute girls. 

Red: (Blushing) C-Cute?

Y/n: Yep, Also those Platelets are Just such Sweetie Gumdrops. So Far I don't see A Problem with this Place?

???: VIRUS!

Y/n: Eh?

You were then slammed into the ground by A Large Figure!

Y/n: OW! What the hell!?

???: You're set to be Killed for being A Virus and Killing several Cells!

Y/n: Huh? I'm Guessing your A NK-Killer Cell, correct? Learned about that in Science Class.

NK: Shut up, Virus! I'll Kill you here and Now!

NK Killer Cell (She is A Strong Powerful Cell who is strong enough to Tussel with nearly anything foreign in the Body/ Is A Bit of A Loose cannon and uses strength and speed over brains/ Is A Total tomboy)

Y/n: Ngh! Get the Hell off me! I am not A Virus!

NK: Shut up! Stop Lying! I don't understand how you beat them all! You're so weak!

Y/n: WELL LET ME  SHOW YOU THEN GIRLIE!

You then threw your head back breaking her Nose before grabbing her by the face sending her skidding back!

NK: Is that all you- Huh?

Y/n: Gear 2!! Full Cowling!! Gum Gum Deleware Jet Bazooka!!

You then Knocked her in the Gut sending her flying as she slammed into A Wall breaking it, and then Another person landed behind you!

???: Stand down.

Y/n: Let me Guess? White Cell? Don't even try.

White Blood Cell (A Cell found in the Body designed to team up and Kill any forgien dangers/ She is A Cold And Calculated soldier made to Kill threats to her world)

White Cell: Just stay down, Worm.

She then charged at you as you charged an attack!

Y/n: Fire-Poison Dragon-!!

Red: STOP! White this is my Friend! He's... Not from around here.

White: Wait, Really?

Y/n: You Know her.

Red: Yeah, we... We dealt with some Virus' Before.

White: Yes, we had. Sorry about that.

NK Then tried to attack you from behind but you grabbed her and slammed her into the ground!

Y/n: Think NK Think! If I were A Virus why would I be out in the Open!

NK: Huh? Oh Yeah.

Meanwhile...

A Group of Virus' were Hiding from White Blood Cells in A Dark Area Being led by A Case of Black Plague as The Virus from before walked in.

???: Hello, Mind if I come in.

Black Plague: What the hell are you?

???: Me? I'm Red Death, but people call me Thrax. 

Black Plague: And what do you want?

Thrax: Full control over this Infection.

Black Plague: No Way! Oh, Boys?

He then snapped his fingers as A Bunch of Virus' all tried to take him but he quickly obscured the Area with Steam and in the confusion he took his claw and slashed the Black Plague in Half Killing him instantly!

Everyone: ...

Virus: Um...So... Boss? What Kind of Plans do you have exactly?

Thrax: (Smirks) ... The Viral Kind.
