The battle has gotten near its climax.First was the double knock out between Scorpia and Melmetal and now Lycanroc has been defeated by Mega Hades. Ash then defeated the toxic spikes implemented by Scorpia and the knocked out Mega Hades. Now both trainers are down to one pokemon each. Y/n with Hydra and Ash with pikachu. Both trainers went for attacks.

Y/n:Hydra use head smash!

Ash:Pikachu use quick attack!

Both pokemkn rush at each other as their attacks connect but with the advantage of three heads Hydra bashes pikachu with on first in the face, another on his head and another on his back sending him crashing to the ground.

Commentator:Get ready for the start of the finale of the pokemon league!

Kiawe:This is bad. It is also if Pikachu is fighting three opponents at once.

Sophecles:Hydreigon is acting like a complete unit with each of the heads working together.

Mallow:How is Ash meant to deal with that?

Lillie:Whatever he does I know he will win

Alola gang:Yeah

Ash:Use thunderbolt!

Y/n:Nasty plot!

As a surge of electricity is sent towards his direction, Hydra uses two of his heads that act like arms to bash the attack away while the top one uses nasty plot.

Ash(thought):He is using two heads to deflect attacks and one to set up. I have deal with that.

Ash:Use electro Web.

Y/n:Bash it away

As an electrical Web is shot towards Hydra he uses the same two heads to destroy the attack.

Ash:Use quick attack!

In the midst of knocking away the electro Web Hydra has left his stomach wide open for a quick attack to connect for decent damage.

Ash:Now iron tail!

With the momentum from quick attack Pikachu is able to knock Hydra back with an iron tail.

Y/n:Use dragon pulse!

All three of the heads send dragonic energy towards pikachu who is knocked far back to the other end of the battlefield.

Y/n/Ash:Use head smash/Quick attack

The two pokemon clash with the exact same attack that started off this face off between them. The three heads try overpower pikachu but this time pikachu is countering with double the force of the attack from earlier.

Y/n:Double heads switch to crunch.

Hydra gets away from pikachu before the two heads grab pikachu's arms and holds him place.

Y/n:Top head use Dragon pulse.

Since pikachu couldn't move he is unable to move away from the incoming dragon pulse and is sent far away.

Y/n:All heads combine for a final dragon pulse.

Ash:Use iron tail into the ground.

As the rhree heads charge up a dragon pulse pikachu stabs his tail into the ground

Ash:Use quick attack with your tail in the ground.

Y/n:Fire!

As Hydra fires a dragon pule pikachu uses quick attack which causes a massive shovkwave which is strong enough to absorb the dragon pulse and redirect it back at Hydra for double damage. Hydra falls to the ground but is able to get back up.

Y/n:Looks like that last attack wasn't enough. Use nasty plot once more.

Ash:Thunderbolt!

Hydra begins to yell out violently as pikacju sends a thunderbolt towards when he released a kanji symbols which crashes into pikachu and blows him towards Ash.

Commentator:Unbelievable! After enduring many hits from Pikachu it seems like Hydreigon has learnt Fire blast.

Y/n:Unbelievable.

Y/n's thoughts are interrupted as he sees something glowing from his pockets. He pulls it out as he holds a z crystal that his parents also left him before death.

Y/n:We are against a wall so let's go!

He begins to activate a z move to which Hydra reacts to.

Y/n:Great dragon of darkness. Unleash your most powerful attack an attack which is as powerful as the sun. Now use triple flare devastation!

Hydra's three heads each send balls of fire which form into three separate sun like fires. Ash's z crystal begins to form into the same z crystal he used against Nihelgo and Mimikyu.

Ash:Let's go pikachu!

He gives his partner his hat as the two of them begin to activate their z move.

Ash:Much stronger than a thunderbolt, 10,000,000 bolt thunderbolt! Yeah this is much much bigger at full power now,! Use 10,000,000 bolt thunderbolt!

Y/n:Now go Hydra.

The two z moves collide as the power of both move is destroying the battlefield. After the smoke clears both pokemon are standing. That was until Hydra collapses.

Kukui:Hydreigon is unable which means pikachu is the winner. Therefore Ash Ketchum is the winner.

Commentator:After a Vicious battle one trainer stands as Alola's first champion. And that champion is Ash!
