[The trainer rides his Lunala through the wormhole, and onto my OCs' island. He doesn't crash. This is technically another universe.]

Yellow: Woah, he opened a wormhole and got here!

OG: Tell me about it.

(He can do whatever, but if there is anyone who he should battle, it's Yellow.)

(Are any of them special creatures or anything?)

*the trainer and the Lunala crash*

[FNaB is a robot]

Yellow: Are you good?

*Lunala emits a cry and nods*

???: yeah, I’m alright.

OG: Good, that looked like it'd hurt a little.

Yellow: *puts two and two together*

Yellow: Do you want to have a Pokémon battle?

???: sure.

Lunala: *Lunala cry* [I can’t battle, I need to keep the wormhole open]

???: oh right..

Yellow: Do you have any others?

OG: *Looks to his left and starts whispering. There is no definite answer to who*

???: Yeah.

Yellow: Alright! Let's start. Electrobuddy, You're up!

*Yellow throws a poke-ball, and it summons a Pikachu.*

*Just after, that, a black, ghostly figure with yellow eyes appears to the left of OG*

*Druddigon comes out of one the pokeballs before the trainer even has a chance to throw one*

???: alright then…

Lunala: *Lunala cry* [who’s that, behind the other guy?]

Reply to the first comment I made in this post to continue.

OG: Don't mind him. He's here to watch.

(Its the Galos region)
*He looks up, along with his right hand pokemon, a Talonflame, perched on his shoulder*

Scenario: safe landing

*[Trainer name] gets off Lunala’s back after it slowed down*

Kayden: huh?
(In the Kalos anime world)

[Safe landing]

???: ah, a region I haven’t been to yet.

Lunala: *Lunala cry* [Well I guess this isn’t Hoenn, Sinnoh, Unova, or Alola then]

???: don’t recognize it.

Kayden: hey!

???: hmm? Oh hey. *they get off of Lunala’s back*

Kayden: where'd you come from, and what's that?

???: this is Lunala, their from Alola. Me personally? I’m from Unova.

Kayden: cool!

???: where are we?

Kayden: Kalos!

I would say go find my stand alone comment saying how they had no name but since it’s hnfindable right now, here it is:

Holy shit my wording is bad, but basically, some creatures might initiate a fight immediately (if you want to go down that path, I personally say it would be fun), and depending on the universe (and if I feel like it) Lunala and trainer may either stop immediately or crash, keep in mind I don’t have nicknames for the Pokémon or the trainer yet.

((oh- ok

(Yeah sorry for the copy and paste)

???: so uh.. what city is this?

Lunala: *Lunala cry* [somewhere we haven’t been yet, let’s go exploring!]

???: alright Lunala.. return. *Lunala returns to their pokeball*

Kayden: what's your name?

* three skeletons were just sitting over a fire.*
( this is the undertale universe if this is accepted)
[ crash sequence]
The one with the dusty hoodie: Oh what the heck is that?
The one with the broken skull: I dunno
[ land sequence]
The one with the dusty hoodie; guys what’s THAT-
The other two: * look up at the two*

* dust turns to killer*
Dust: Your name almost got us killed-

Druddigon: *Druddigon cry* [I was actually referring to what they said.]

???: yeah I heard them.

* Killer and Dust argue*
Horror: uh…. Guys?

Druddigon: *they roar* [QUIET] *their tail slams into a rock and smashes it*

* they all fall silent, and horror looked quite shocked*

???: Druddigon…

Druddigon: *Druddigon cry* [What?]

???: calm down.

* dust and killer start fighting again*

*Druddigon slams their tail into the ground, using earthquake to hit both of them, the result is a fissure opens up in between them and a small wall of earth rose up filled the gap between Killer and Dust.

* they both look confused*
Horror: Thank you! I was TIRED of thier fighting!

???: nice job Druddigon.

*The Druddigon says nothing*

[Crash]

*the trainer sends Druddigon and Flygon out, Lunala stats by the wormhole* [battle scenario]

*Flygon and Druddigon look at each and look back at you, they look confused but they seem determined, they allow you to make the first move*

Dust + killer POV: Mission failed- we’ll get em next time!

Druddigon: *Druddigon cry* [Permission to use flamethrower?]

* the Lunala finally speaks up*

Lunala: *Lunala cry* [how about we head back now, that’s enough for… wherever we are.]

???: I agree with Lunala. Druddigon return.

*Druddigon returns to their pokeball, the trainer hold back onto Lunala’s back*

* horror waved bye*

*The trainer waves goodbye before Lunala dives into the wormhole, the wormhole then closes after both of them leave*

* horror watched as the hole closed and went back to the two*

[that’s the end, Trainer leaves]

[ lol]

Stays*

All three get up*
The one with the dusty hoodie: What are those
The one with the broken skull: I know just as much as you, Dust
The one with black stuff coming out of his eyes: * wakes up* wha- What the heck is going on?

???: ?

*Druddigon looks even more confused, it gives a confused cry to the trainer, they look just as confused*

???: should we fight?

*Flygon nods, it looks like it has fun battling other creatures, Druddigon looks rather serious*

Druddigon: [moves last]

[Flamethrower] —> [Revenge]

Flygon: [moves first]

—> [fight] [Bag]
[Pokemon] [Run]

—> [Sandstorm] [Earthquake]
[Dragon Breath] [Giga Drain]

* the three look at each other out of confusion*
Dust: what are you doing?
The one with the broken skull: Dust he’s battling us- I think?
The one with the black stuff pouring out of his eyes: Horror- that’s obviously what they’re doing!

*The sandstorm rages on*

Flygon: *Flygon cry* [do you guys not want to battle?]

*Druddigon hesitates to use their move, they do not use it*

???: … Flygon is asking if we aren’t fighting. Do you want to battle?

* the three get thier weapons out*

???: I asked if you want to, not that we have to.

Dust: I don’t wanna-
Horror: me either.
The one with the goop coming out of his eyes: I do!
* dust put his hand over the skeleton’s mouth* Dust: Killer no.

*Druddigon looks even more serious and ready for battle now*

Druddigon: *Druddigon cry* [what was that I just heard?]

*Trainer facepalms*

???: Flygon return. *Flygon returned to its pokeball*

Lunala: *Lunala cry* [are we going back so soon?]

???: not yet Lunala.
