Introdution Fan-Fic: Pokémon Thalos - The Age of Darkness

A long time ago, two kingdoms fought each other and caused many deaths, including humans and Pokémon. Both kingdoms were islands and the war between them made the underwater volcano, Folker, eruption. And by this happening a new island was created, and was named Thalos.
Many yeas passed and now all the world is in peace and harmony, but it´s all about to end...

(In an unknown place)

???: So... how it's the preparation for the launch?
Recruit: It's ready Mr.Seamus!
Seamus: So... let it begin...

(meanwhile in New York City)

???: MOM!!! WHERE ARE MY SHOES!?!?
Mom: It's under your bed Damon! And come down now for the breakfast!
Damon: Ok ok! I'm coming...
(some minutes later)
Damon: Oh, mom, I'm so excited! Today is the last day of school, I can't believe it's over!
Mom: It's true, it looks like it was yesterday you were going to your first day...
Damon: Hahaha, it's true.
Mom: Ok then! But now you're late for school, so grab your things and run!!!
Damon: Okay... see you later!
Mom: Bye!!!

(on the way to the school)

???: Damon!!! Wait!!!
Damon: Hey, Anna! Come quick, we are late for your last day at school!
Anna: Yeah, yeah, I know, let's go!

(in the entrance of school)

Anna: Trevor! Thanks for waiting us!
Trevor: No problem... but come on, we have to go!
Damon: Sure!

And then, Damon, Anna and Trevor enjoyed their last day at school, but when they were leaving the classroom, a big thunder hit the school...

Damon: WHAT WAS THAT?!?!
Trevor: I don't know, it's really dark, this must be a blackout!
Anna: NO! NO! NO! I hate dark places!!!
Damon: Guys, we need to get out of here!
Trevor: I agree! Let me get my cellphone so we can have some light...
But apparently Trevor's cellphone wasn't in his pocket anymore
Trevor: I can't find it!!!
Anna: I want to go home!!! (*sniff*)
Damon: I think we should wait until the light come back!
Trevor: It's the better option right now, I can't see a thing...
Anna: Ok...ok... let's wait then...
A hour later...
Damon: Look! The energy is back!
Anna: YES!
Trevor: But wait... there seems to be no one here!
Damon: Yeah, it's too quiet, but let's go, I can't stay here anymore!
When they arrived at the school entrance...
Anna: Hum? This is not as I remember...
Damon: Is it just me or this isn't New York?
Trevor: Wake up! Wake up, Trevor!
Anna: Trevor, we are not sleeping...
Trevor: This can't be true!!! How could we not be in New York? Look, the school is right behind us....
But there was nothing behind them
Damon: Whaaat? The school was here a minute ago, and now it's gone? This is really weird!!! What did my mom put on my food today?
Anna: I think this is not New York... we should look for some place and get information!
Trevor: I'm with you, Anna!
Damon: OK! Let's go!
After one hour walking in the middle of some woods, they found a cave.
Trevor: Look! There's a cave there! We should spend the night there, it's getting dark now.
Damon: Good idea, I will look for some sticks and make a bonfire.
Anna: I will try to find some water... I'm so thirsty!
Trevor: Fine, I will keep the guard!
Some minutes later, Damon and Anna heard an scream.
Trevor: HEEEELP!!!!
Anna: OMG! It's Trevor! (running to the cave)
Damon: What was that? It must be Trevor!!! WAIT FOR ME BUDDY!
at the cave...
Trevor: HELP ME GUYS! THIS CREATURE ATTACKED ME!
Damon: WTF IS THIS?
Anna: It doesn't look like a normal animal!
 Dustoxxxx!!!!
Damon: Danm! IT'S A HUGE MOTH!
Anna: What are we gonna do?
Trevor: LET'S RUN!!!!
 Dustoxxxx!!!! (Attacking them)
???: NOW! USE YOUR ICE BEAM!
 Onnnnnn!!!! (releasing a frezzing beam by it's mouth)
 Dustoxx.... (felt in the ground)
Damon: Ok, now it's getting more weird!
???:  Who are you? What are you doing in these woods at this time?
Trevor: I'm Trevor, this is Damon and Anna, we are from New York, and we have no idea of what's going on!
???:  WHAT?! You said New York? This place doesn't exist!
Anna: What do you mean?
Prof. Allen: I'm Professor Allen, one of the most famous Pokémon Reseachers and I have never heard of this place! Not here in the Pokémon World!
Damon: What did you say? Pokémon World?
Anna: What is this world?
Prof. Allen: So... you don't know the world you live?
Trevor: Our world is called Earth, and I don't think there is another one...
Prof. Allen: Earth? Come on, let's go to my Lab and you explain me your story.
Damon: Ok, come on guys!

Now, Damon, Anna and Trevor were transported to another world? What are those animals? What's the Pokémon World?
