"So, you made it in before me, did you?" Mewtwo sneers as he lands smoothly on the ground- a psychic aura still surrounding his body.
"It would seem so. I was wondering when you'd finally decide to show up. Perhaps it's true that your fame IS fleeting." Charizard grunts and a jeer flame shoots from his mouth.
Mewtwo glares and his eyes flash blue for a split second. "I was here first. I am the strongest Pokemon in the world, you insolent fool. Perhaps its time that I teach you your place."
"Hm. Well honestly, you're the only real competition in terms of Pokemon. Perhaps you don't understand that this is exactly what I wanted to hear from you. I want a fight that is actually a fight- one where I can show my full potential!" A glowing flame envelops Charizard. "I know that I may not stand a chance in my regular forme. But you will know true strength!!" Charizard roars and stands proudly in his "Mega X" evolution. "Greninja, Pikachu, Lucario and Jigglypuff...those weaklings could never compare to us, Mewtwo."
Mewtwo closes his eyes and a grin grows slightly on his face. "Well, Charizard- I have to say; you make being a 'Smash Brother' worth the time in effort. Perhaps after we find out who is truly the strongest- we can team up and show this entire realm our dominance."
"Its a deal. But- until then..." Charizard flies up into the air and his tail burns fiercely.
"Right, let's do this." Mewtwo readies a Shadow Ball, eager to have the "Smash" battle he's waited too long for.
