An Alien In Alola

Brother vs Brother

Greninja: you...

???: long time no see... brother.

All: what?!

Everyone was shocked and by this revealed. This Shiny Pokemon is Greninja's brother.

Bolt: he's your brother?

Pheromosa: why haven't you told us you have a brother?

Tom: and why does he have sharp fangs and green eye's?

Greninja haven't answer their questions, he's still angrily glared at his brother.

Wafu: allow me to introduce myself. The names Wafu. Also, who are your new friends, Koga? Especially those femalePokemon, but most importantly the fox one.

Koga: you leave them out of this! It's between you and me!

Braixen: wait, you already have a name? And it's Koga?

Koga: *sigh* yes, but nows not the time.

Sylvia: seriously, what the fuck is going on?!

Wafu: what's going on here is you are getting in the way between me and my brother.

Wafu throw Water Shuriken and fire Water Pulse near them, which caused an explosion and knocking them out. All except for Koga who was standing his ground.

Wafu: ahh, that's more like it-

He then saw a Water Shuriken fired at him by Koga, he dodged it and had a creepy grin on his face.

Wafu: oh, getting ready to fight. Are we brother?

Koga didn't say anything, instead he stick out his tongue and wrapped it around his neck, and got into a fighting pose.

Wafu: I'll take that as a yes.

He then used Night Slash, but instead of purple or blue it's green. Koga also use Nigh Slash, Koga quickly jumped and was about to slash Wafu, but the Shiny Pokemon blocked. He then used the other Night Slash and with a mighty swing he got a hit on Koga, cancelling his attack move but he's still standing.

Wafu: still standing? Boy, you sure had a lot of training without me.

Koga: you never teach me any fighting moves! You were always doing those 'things' to the inesent!

Wafu: hmph. I was gonna show you moves when you reach your second evolved stage, so you can join me. It's not to late to join you know~.

Koga: never!

He shouted in rage and used Quick Attack and used Night Slash to get a hit. But Koga dodged it and used Hydo Pump, which caused him to be pushed near a tree and crashed. Wafu then ran at him with Water Shuriken, Koga quickly got up on his feet and used Smokescreen. Wafu fired the Water Shuriken, but didn't hit Koga, because he got away in the Smokescreen.

Wafu: clever boy.

As he was surrounded in Smokescreen, Koga used this opportunity to land a hit on him since he's hiding in the Smokescreen. He quietly makes his way towards him and when he is right behind him, Koga was about to use Hydro Pump, but he was attack behind by a shadow figure, which is Wafu's attack move called Shadow Sneak.

Wafu: nice try brother, but I'm always one step ahead of you.

He then use Hydro Pump, but Koga also use Hydro Pump. When both attack moves clash together it created an explosion that causes the water to fall from the sky, similar to rains. But that only lasted for a few seconds, Koga then use Double Team, which there is now six of him and they all use Water Shuriken. Wafu focus his energy and used Dark Pulse to destroy the Water Shuriken, and the clones. Koga realized none of the attack move is working, so it is decided to do it an old fashioned way.
