Thrown into battle! (Male!Monster hunter gen 1-5 reader x Pokémon)

Uncontrollable

Oh...oh no...
How....horrid.
This feeling....
Don't even beg for mercy,why should you?
No,not from this hell send...
Mercy was nonexistent...don't even think about the word,let alone meaning.
Wipe it from your mind.
It doesn't exist anymore.

The boy lifted both arms and slammed them on the ground,through the tiles,through the dirt,through the crust.
Plants and flowers grew grey,the dry rock cracked in half,rumbling the very island and sending a shockwave beyond.
Kill them...
He gripped the already broken tiles,crushing them to dust as his skin ripped,snapping veins and springing blood.
His team looked on in horror,was this how he looked like when he was shifting? Under all the smoke?
He lifted a hand and tore out the knife stuck in his head,it came out with a Crunch and bits of pink mush.
His head steamed and closed up.

The people around cowered,they were still trapped,with him.
Cutiefly flew closer and poked his cheek with worry,making him look up at her.
Time slowed as his eyes dilated and he smiled,showing his canines before pecking her temple and pushing her back with the group.
Then,he stuck out an arm,glaring at the crowd.
The familiar pink aura engulfed it as his team was huddled together and covered in a barrier,they looked at him with tear pricked eyes as they banged on the invisible wall.
The lights flickered as the crowd of people looked on in fear and terror.

The boy held a finger to his lips and winked at his team,letting them know he'd be fine and to just stick to the skies for now.
It wouldn't be long...
And with that,they crashed through the roof and floated off.
He turned his attention back to the crowd,growling out as his jaw snapped and muscles bulged,the skin around his shoulders and chest grew green and stretched,showing the glowing muscles.
A horrid aura of black and red engulfed around his form.
Faint spikes grew along his back and sides.
His arms shrunk and he fell on the floor,growing bigger and bigger.

As the crowd prepared to meet their fate,he looked at them with those piercing yellow eyes.
His legs snapped up and lifted him off the ground,slamming his large form into the ceiling.
...
The outside was silent,his team had their eyes glued to the shop,waiting for something,anything.
Then,a terrible roar,a deep guttural one at that.
The sound caused them be ready,staring down at the scene.
...
It was quiet...not a sound to be made.

"Trap...? Trap!?"
Trapinch lifted herself onto the invisible barrier,shooting her eyes around for any movement.
"Cute..."
Cutiefly landed on her head and sighed,trying to calm her down.
Misdreavus and Formantis were nonchalant though,knowing he'd be ok.
Trapinch turned to them,wondering how in the world they could be fine with this.
"For." "Dreav."
They were clearly confident,but decided to cut her some slack.

They scooted closer and comforted her,smiling and telling her about him.
How amazing he was,his strength,confidence.
Perfect for a trainer,and how they all should be.
As her mind began to be led from the thought of the shop and nonexistent danger the boy was in,she calmed down,thinking about him.
A faint blush came over her face as she giggled to herself.
The others had sweat-drops on their temples as they knew what she was thinking.
Hell they all did...
...
Who wouldn't...?
But as they were talking the roar came again,way LOUDER this time,the sound-wave vibrated the barrier,shocking them.
How loud was he able to scream!? To the point of REACHING this high in the air?!
If they could hear it...
Surely something else could...

...
Then...
Oh....
The devil might as well came from the horrid depths...
That awful feeling came back to them,no matter how far they were...
They stared and went wide eyed as the boy's massive form crashed through the roof of the shop,he raised his snout to the sky,jagged teeth shining in the moonlight.
He snapped his jaw apart,saliva and drool dripping down his chin.
Then,for the third time,he roared as loud as he could,cracking the glass in the ENTIRE area.
He looked like something from nightmares,deep green and like...like...
...
A pickle?
