Steven: that is awesome!
Sid: now you'll save your home!
Diancie: I wonder if I can create a heart diamond now
Steven: give it a try
Dace: please!
Diancie breaths, but not before a hint ship comes over them. Malaise and Argus come down
Malaise: congratulations diancie! Now you have the power to create real diamonds!
Diancie: it's you!
Sid: I thought you were helping us!
Malaise: hah! Yes we were, but now we'll be taking diancie!
At that moment she unleashes her chasnaught
Steven: what's going on?
Malaise: I knew diancie was gonna come here to find xerneas, because that dumb Pokémon didn't yet master her diamond powers
Argus: it's hard to imagine diancie not making diamonds. It's like eating chocolate without coco in it. Totally worthless!
Steven: who are they?
James: Argus steel
Meowth: the most mischievous thief out their
Jessie: and that's her daughter malaise
Malaise: chesnaught!
He uses his vines to grab diancie but then greninja comes and snatches her as Ryan comes
Ryan: we're taking diancie with us
Argus: after them!
They chase after them
Steven: diancie!
They venture straight into a deep dark cave below a petrified forest
Diancie: if you want diamonds, I'll give you some! Please let me go! I have to get back to my domain!
That's when a dragonfly Pokémon comes into e cave. Then delphox comes from behind them and uses flamethrower causing Ryan to land into the water disturbing what lies beneath. Delphox attacks greninja as marline comes behind diancie
Marlin: thank you!
Diancie: let me go!
Ryan: Marin
He leaps out of the water and across from her
Marlin: you look fabulous! Even when your angry Ryan. See you later
She carries diancie off but Steven and latias soar down and scoop diancie out of her arms saving her
Steven: (blows raspberries)
The chesnaught comes missal blasting the two who miss. He lands into the water disturbing the dweller beneath even more. Chesnaught blasts Steven and diancie out of the air making them crash into the water. Now the dweller beneath was just pissed. The gang make it to the scene with zephyr who was watching from one of the petrified trees
Marlin: you miserable pest
Latias: KEEP YOUR HANDS OFF MY BOYFRIEND!!!
She blasts marlin out of the air, but Ryan comes and catches her in his arms
Marlin: but why?
Ryan: why! I just....
He embarrassingly drops her into the water where she saw what lies beneath. That's when the water around them turned purple causing what lies beneath to get madder than ever. He absorbs the black die in the water and raises from the water with everyone watching
Dace: oh no! Princess diancie! Steven! Latias! You must leave their at once!
Too late, cause the giant dweller from beneath roads up from the black depths as the sky grew dark
Zephyr: (clocks tongue) nobody listens....
The dweller continues to rise until it became visible
Dace: the cocoon of destruction!
The cocoon started to burst apart until it revealed... yveltal, the bringer of death and destruction himself
Steven: (high pitched) fuck me
Yveltal; thou have destined Thai from Thai slumber! For this act, thou shall be punished, by sudden, immediate DEATH!!!
Steven: RUN FOR YOUR LIVES!!!!!
As he screams the bird exploded until He was covered head to tail with flames of fury like a mighty Phoenix. He lets out a furious screech with flames bursting out of his beak straight up into the sky until it was covered in red flames. Everyone makes it out as yveltal flies to the air destroying everything in his sight as it bursts into an inferno of destruction. At that moment, Ryan who was holding diancie watch as his Pokémon get petrified to stone in the destruction
Everything around them gets petrified. Diancie tries to escape but marlin comes and snatched her up as they head down the jungle. Yveltal leaves nothing but chaos as he mystified all her Pokémon allowing diancie to escape. The jungle was being thrown into chaos as yveltal rained his catastrophe yet again. Miles away, xerneas senses the disturbance from the jungle. Diancie and the gang regroup, but only for malaise and Argus to kidnap her and take her to their ship. But yveltal blasts at them petrifying their pokemon
Yveltal: thou shall all pay the price! BY DEATH!!!
He soars the sky laying waste to everything in sight, but Steven thunderbolts the beast saving them
Jessie: let's get out of here!
Steven: guys! No!
Steven blasts his petrification blast saving them
Steven: we need to stay together!
____
Marlin: who's that Pokémon?!
She cries in a remote part of the jungle
Marlin: who what it did to my Delphox
Ryan lands right next to her
Marlin: Ryan
Ryan: it's alright, let's forget about diancie
He removes his mask and lends out his hand. She takes it, just as yveltal comes petrifying them
____
The group make it to a clearing in the jungle as they see the destruction around them
Dace: no. The all earth forest is dying again
Steven comes with diancie. Just as yveltal comes with his petrification blast. Diancie comes in front of them and gets her hands out. As yveltal fires, she blocks it with a heart diamond. Only for the blast to destroy it
Dace: princess!
They all come to the duo
Diancie: my powers... still not enough
Yveltal lands right across from them
Yveltal: I shall not let thee continue to live!
Steven: run!
They do so as the fire bird blasts them again chasing them like a wolf chasing prey. He petrification blasts them but Steven thunderbolt blocks to save them but accidentally makes it hit marek and the carbink
Marek: Steven, please protect princess diancie!
At that moment, they were petrified to stone. Yveltal blasts them again tossing Steven off the nearby cliff. Luckily latias and manny grab him in time, just as yveltal comes flying around the corner. Diancie lion around and sees all the destruction she caused
Diancie: I was supposed to protect my people, (sheds tears) I wish I was never born! I wish my mother was here!
Latias: don't give up! Or we'll all die!
Manny: stay strong kid!
They all continue to help pull Steven out of the cliff
Latias: Steven! Are you okay?
Steven wakes up and flies up to the group relieved. But then yveltal comes right in front of them. He petrification blasts them again
But Steven thunderbolt blocks it. Diancie gets in front of them all as yveltal flies around remembering what xerneas said
Memory: the power to nourish life lies within you yourself
Diancie: I'll never give up! EVER!
At that moment, she shined as bright as her powers until she transformed into her mega form in front of them all
Clement: she, mega evolved!
Yveltal dives and soars right toward mega diancie. She summons her energy to create a true heart diamond to block his petrification blast, and it didn't even break at all!
Dace: that's it! A heart diamond!
Diancie transforms back into her regular form as the ship Argus and malaise come. They then come around to blast at yveltal with their missals but miss as the hint bird comes and blasts them directly, making it fall straight to the water. Yveltal then blasts the gang again, but was counter blasted. The group look to see it was xerneas!
Steven: xerneas!
She looks right at yveltal who prepares to petrify her. Xerneas antlers shine as bright as a rainbow and blasts his attack away. She uses her psychic powers to telepathically calm the beast. Yveltal's eyes dim from purple to their pure blue. The water returns to normal as he flies off to pets unknown high into the mountains
Sid: he's gone
Zephyr: we're safe now
But then... Steven feels faint and falls right in front of the group!
Latias: Steven!
She lowers to him as they see he was hit by yveltal!
Clement: he's been hit!
Steven:... look like... this is it for me....literally stone dead by a psycho bird....
They all watch in horror as Steven is petrified to stone
Latias: Steven!
Diancie: no...
Diego: no....
Sid: oh Steven, we knew you so well. WHY DOES IT ALWAYS HAVE TO BE THE MOST CLOSEST ONES WE KNOW WHO HAVE TO GL FIRST!!!
Sid falls on his belly crying like a baby
Latias: oh Steven...
She starts to cry on what was left of her loved one
Latias: oh Stevie cake!
But at that moment, the ground starts to turn green. They all look to see xerneas healing the jungle around them
Diancie: xerneas
Latias looks to the stone statue of Steven who transforms back to Steven!
Steven: ugh..... Mom... is this heaven?
Latias: Steven!
She grabs him by the neck and hugs him tightly. At that moment, everyone transforms back to normal as the entire jungle heals back up
Dace: xerneas is sharing her life force
At that moment, her hooves plant into the ground as she transforms into wood and shifts into a tree, her body becomes wood, her antlers become branches and her face disappears in the wood
Clement: she's becoming a tree
Dace: xerneas is choosing to slumber here in this land, to protect the balance of nature
Bonnie: but does that mean?
Steven: she's... dead?
But at that moment
Xerneas: (v.o) their is nothing to be sad about, princess, and Steven
Steven: what the?!
Xerneas: (v.o) you see, this is not death. This is the promise of life. And the beginning of hope
Steven: the promise of life and the beginning of hope
At that moment, the jungle healed as everything yveltal destroyed transformed back to normal
Steven: thank you xerneas
As for the thieves and their Pokémon, they changed back to normal, even Ryan and marlin
Marlin looks to Ryan and kisses his cheek. With Argus and malaise, they transform back and come out for their ship, but when they looked to the water?
Crocodile: guess who!
_____
In the carbink caverns, mega diancie was at work fixing her kingdom. She summons all her strength and makes a new pure heart diamond
Mega diancie changes back to normal
Marek: princess!
Dace: it's wonderful!
The heart diamond them purifies the caverns until they were as good as new
Diancie: everyone. I want to thank you al so much
Steven: boy am I happy we met you
Serena: me too
Clement: me too
???: as well as I
They turn to see mewtwo
Steven: and where have you been missy?
Mewtwo: just looking for a good spot to rest when this adventure was over
Steven: oh... you were just looking for a cool down spot
Diancie: even if that happens, we'll always be friends
Steven: I guess so
Sid realizes something and looks to bonnie's pack and finds her diamond still existing
Bonnie: my diamond! It didn't disappear!
Serena: beautiful!
Manny: I guess that's your first event pure diamond
Steven: and that's the symbol of our friendship!
Diancie smiles at that remark
Diancie: yes!
Bonnie: princess, I'd like you to have it
She gives it to her
Diancie: I will cherish it!
She looks at it with a huge smile on her face
