(Y/N wakes up and finds himself in Cartoon Network City)

Y/N: What?

(He looks around and sees various Cartoon Network Characters.)

Y/N: Am I... dreaming?

(Suddenly Gumball comes in)

Gumball: Hey. I don't know you.

Y/N: I know. Maybe I'm just a foreigner who ended up here by accident.

(Then Dexter comes in and sees Y/N cosplaying as Optimus Prime)

Dexter: Hey, man. Are you by any chance...

Y/N: Cosplaying Optimus Prime? That's right. You got me.

Supergirl: (comes) A-ha. I knew it!

Dexter: Come on, Kara. He must be kidding.

Y/N: No. It's serious. I don't even have superpowers. And besides, this "armor" is made of plastic?

Rigby: (sees Y/N) Boy... That boy made the best cosplay of Optimus Prime I've ever seen in my life.

Mordecai: Man... Almost like the original one...

(Back to Y/N talking with the characters)

Supergirl: I must admit. That was a good cosplay indeed.

Dexter: When you want to become a superhero, find me in my house. I can make a suit just like your... cosplay... Just better.

Supergirl: (sighs) Dexter... Always flattering himself.

Gumball: This really makes me... ANGRY!! (turns into Super Saiyan)

Y/N: Wow, wow, wow, wow, wow, wow, WOW!

Robin: (comes in) And they call me cocky...

Supergirl: Great... It's that superhero wannabe...

Robin: I'M NOT A FAKE!!

Supergirl: I DON'T CARE!!!

Samurai Jack: Ah... Here we go again...

(Samurai Jack stops the arguing, then he looks at Y/N)

Samurai Jack: You are new here, right?

Y/N: That's right. I'm Y/N L/N. Where am I?

Samurai Jack: You are at Cartoon Network City. Call me...

Y/N: Samurai Jack. I know. Look. Maybe you won't believe me... But I came from another dimension.

Rigby: Did you hear that, Mordecai? He came from another dimension!

Y/N: I need to get back home.

Supergirl: Sorry. But you're not going anywhere until you tell me more about you. Or else...

Samurai Jack: Supergirl!! How many times do I have to tell you?

Green Lantern (Jessica Cruz): Jack is right. No violence around here!

Samurai Jack: So... Y/N... Something tells me I need to prepare you.

Y/N: Prepare me? For what?

Robin: You're gonna be surprised!

Dexter: Y/N. We can teach you things which you would never learn somewhere else.

Y/N: Well... I guess I'm staying.

Mordecai: Cool!

Mordecai and Rigby: OOOOOOOOOH!

(Something tells me that it's only the beginning of a great adventure)
