Ok here is another story, this one has been on my mind for a while and I decided to act on it.
(Ash's POV)
We were still in Alamos Town after the incident with Dialga, Palkia and Darkrai. We were all about to head out to the next town when we saw Paul. Dawn's face immediately darkened and she spoke.
"Hey look, its Paul, I wonder why that jerk is here?"
As soon as she said that, Paul was alerted to our presence. He then spoke.
"Hmph, if it isn't that weakling Ketchum. How about a battle? I need something that my pokemon could use as punching bags"
I growled as I agreed, the battle was a 3 on 3 battle. Paul chose his Torterra and I used Infernape (yeah I know that it's still a Chimchar here but I upgraded it to Infernape). The battle was tough but in the end Torterra defeated Infernape. Then it was his Ursarang vs my Charizard (again, yes I know he doesn't actually have it here but bear with me), Charizard used seismic toss and Ursarang was knocked out. Finally it was Paul's Electivire vs my Pikachu. I told Pikachu to use Volt tackle and Electivire dodged. Electivire was then ordered to use thunder punch and Pikachu was thrown across the field. Blows like this went on for a bit until my partner was struggling to stand, Paul told Electivire to use brick brake and Pikachu was knocked out. But Electivire wasn't done. I was horrified when Paul ordered him to use giga impact on my unconscious starter. I knew that from the wounds that Pikachu received, that this would kill him, but before I could act, the move was activated and hit Pikachu with a devastating force. He was thrown roughly against the wall and we heard a sickening crunch, Paul smirked victoriously as he recalled Electivire. I ran over to my starter and tried to see if it was ok but I saw that my best friend wasn't breathing. In fact, from the seriousness of his injuries, he wouldn't even make it to a pokemon center. I was scared for my buddy and I couldn't control letting tears leak out. I heard Dawn and Brock run over to my and I saw them mirroring my expression. I then saw Alice run over with a horrified expression on her face. Paul was long gone but I could care less, I was too focused on my dying friend to care about him. Alice then spoke.
"I'll see if I can summon Darkrai. I heard a rumor that he has an ability where he can heal a pokemon and that healed pokemon will grow shockingly stronger and become immortal."
I nodded as I picked up Pikachu and we headed to the garden where we first met Darkrai. When we arrived I heard Alice mutter something before Darkrai appeared. He looked at Pikachu and he instantly knew what Alice wanted. He then spoke.
"Why have you summoned me Alice?"
"Pikachu is dying, he needs your help!" Alice responded.
Darkrai glared at her and spoke;
"I won't help him, if I do then there will be a severe consequence".
I was shocked, he had the power to heal Pikachu but he refused to help us? I wouldn't let my buddy die, not now so I spoke.
"Look Darkrai, Pikachu is DYING! Look if you have the power to help him than you must. Please, I'm begging you. He's my best friend; I can't afford to lose him."
Darkrai turned to me and stayed silent for a moment as if debating if it should help us or not but after a moment, he finally spoke.
"Fine, I'll help him! Just Know this Ashton Ketchum. When the consequence reveals itself; AND IT WILL, just don't say I didn't warn you."
I was shocked and relieved; shocked that he knew my full name and relieved that he agreed to help. Darkrai then floated over to Pikachu who looked at him weakly. Darkrai growled as his eye glowed violet and three sharp talons appeared on his hand, He then to all of our shock stabbed them into Pikachu. Pikachu obviously not expecting that, screamed loudly and we all watches as Darkrai stepped back and then faced us, then growled as he faded into the shadows. We turned to Pikachu as we saw a violet glow emit from his body and he started writhing. Pikachu unclenched his eyes and when he opened them, instead of the normally black, cheerful eyes, they were blood red and had a small trace of evil in them. Then his eyes went back to normal and he got up. I let out a cry of joy as I hugged my pokemon and he hugged me back. I was happy to have him back but Darkrai's words were imprinted into my head. "When the consequence reveals itself; and it will, just don't say I didn't warn you." I couldn't help but wonder what consequence he was talking about. I was also wondering about Pikachu's sudden eye color change but I pushed those concerns to the back of my mind. Dawn then spoke.
"Do you guys think that Pikachu is stronger?"
I grinned as I looked at my buddy and serious determination appeared in his face. I then spoke.
"There is only one way to find out."
I then pulled out a poke ball and released my Torterra. And to my shock, with an impossible burst of speed, Pikachu was already far away from Torterra in a battle stance. I grinned as I Torterra to use tackle. I was expecting Pikachu to dodge and then use an attack to counter but what he did shocked all of us, Torterra included. He zipped to Torterra and with a small grunt. PICKED HIM UP! I was shocked, Torterra was at least like 5 tons and Pikachu just picked him up and was holding him over his head. Those red eyes returned as Pikachu then let go with one arm and was only holding Torterra with one hand. To say we were shocked was an understatement. Pikachu, who was a very small pokemon, was easily lifting one of the heaviest pokemon known to man. Pikachu then tossed Torterra, who landed upside down and couldn't get up. Pikachu then calmly walked up to Torterra and to further our shock, he used punishment on Torterra's face. Torterra had swirls in its eyes. Dawn spoke.
"T..t..that's..i..impossible! Since when could he use dark moves?"
I was shocked, in all honesty, he couldn't. Punishment is not only very hard to learn. It's scientifically impossible for Pikachu to know this move. I took out my pokedex and scanned Pikachu and it said horrified us.
"Pikachu, the electric mouse pokemon, it stores electricity in the red pouches on its cheeks. A thunderstone will allow it to evolve into Raichu. This Pikachu's move set includes. Thunderbolt, Volt tackle, Iron tail, Iron head, Electro ball, Agility, Thundershock, Thunder, Fury swipes, Punishment, Flare blitz, Flame wheel, Seismic toss, Sleep talk, Payday, Teleport, Force lightning (Yeah I know starwars), Flamethrower, Water gun, Attract, Hypnosis, Bite, Leaf storm and Force push (again, starwars).
We were all horrified that Pikachu knew all these moves. Most I've never even heard of. I looked at Brock and spoke.
"Hey Brock, do you know what Force Lightning and Force push are?"
Brock shrugged as did Dawn. I then saw her remove a pokeball and she sent out Piplup. I got her idea and we told Piplup the situation and he understood. He walked up and stood across from Pikachu. Brock, Dawn and I released all of our other pokemon and informed them on what happened and they were shocked as well. Buneary looked at Pikachu in shock then stood by the other pokemon to watch this fight. I then spoke.
"Pikachu use Force Lightning on Piplup."
He grinned and raised both hands towards Piplup and to all our shock, a strong blue lightning came out of each of his fingers. Piplup started screaming in pain, something he normally never does as Pikachu put more power into the attack. I then spoke again.
"Now Pikachu while he's down, use force push."
The lightning ceased and then Pikachu pointed one paw towards Piplup and to all our shock, he was levitated into the air. Pikachu then thrust his palm outwards and Piplup was thrown into a tree, breaking it in half. That shocked all of us because if Charizard punched that exact tree as hard as it could, it wouldn't even crack it. Dawn recalled the unconscious Piplup and we recalled all our pokemon except for Pikachu and Buneary, who refused to return to her pokeball. I looked at my starter pokemon, who instead of hopping on my shoulder like normal; he decided to walk next to me. I looked at him and I thought to myself. What happened to you buddy?
