Welcome, this is my first official story on this website so I may not be that good, although I am trying my best and putting my effort. I hope you like the story. Anyways, I'd just like to say that I do not own any of the characters, just the story.
After so many years of being absent, Mewtwo was finally back to the fray, he seemed to have gotten stronger but that has yet to be proven on the battlefield. Yet, there were two fighters he just didn't like, one that was stealing his spotlight. He's a veteran also and that happens to be Lucario, he also has power like his but not exact. There was another fighter who he heard was another newcomer, Greninja, both quick and quite powerful. Now it was time, to strike at them...
Mewtwo, after so many years of not fighting the others, was now back to prove he's as twice as powerful as he was back then in the melee. But his replacement in the brawl was replaced by Lucario who happened to be right at the other side of the field, joined by Greninja. He wasn't afraid of them, as he thought of himself as the most superior. He charged a shadow ball and quickly hurled it towards them, both dodging at the same time. Lucario ran towards him and tried to grabbed him, only to be grabbed instead and thrown towards Greninja who was only watching, got knocked back. "Gr... you're not helping!" Lucario shouted at Greninja who was now was disappointed at himself. "Gre!" Greninja through a water shuriken as Lucario charged a aura sphere, Mewtwo went towards Lucario and used his confusion attack to knock him out, yet he failed as Greninja leaped and punched him. Lucario then hurled his ball of aura at Mewtwo who was knocked back, Mewtwo needed someone by his side. He underestimated them yet this wasn't the time to feel bad.
Although, who could help him at a time like this? Charizard, seemed like a good fighter. But he was heavy although powerful, though Mewtwo's opponents were quick. He need someone who was quicker... He then saw bolt of lightning shock Greninja and lightning hit Lucario, who could it be? "Pika!" shouted... Pikachu! Of course, he was... glad that he was helping him. Mewtwo got up and charged another shadow ball, although he held onto it and went closer to Lucario who was getting up as well, he hurled it towards him and bam! Lucario was knocked back further, Pikachu used his quick attack to get to Greninja, who kicked him and through a water shuriken. Pikachu then summoned another cloud of lightning, shocking Greninja and shocking him again with another bolt of lightning which sent him flying across the field.
Pikachu went in for the finishing move, another lightning attack followed by attacking him with his tail. Greninja was then knocked-out for sure, which left Lucario who was fighting Mewtwo. Mewtwo tried using his confusion which was successful, followed by a whack from his tail and then a not-so charged shadow ball. Lucario took great damage, but that just made his aura stronger, running towards Mewtwo. He punched and grabbed throwing him across the stage and then a aura sphere, hurled it but ended up hitting Pikachu who had saved Mewtwo although was knocked out. Mewtwo wasn't really affected by the loss of the electric mouse, he was as cold as ice, he mainly cared about winning or at least in this case. Mewtwo then went and charged up another shadow ball and hurled it at Lucario which was an instant knock-out. Game.
