>Ash is in a battle with the rival
>Charizard is losing, rival is being an asshole about it. "That's the best a Charizard has? You're not a good influence on it at all!" and so on.
>Ash is getting upset, but can't get Charizard out of the mess
>As he readies the pokeball to recall Charizard, Charizard swings his wings hard enough to make Ash drop the ball
>Charizard then recklessly rushes into the fight, fully ready to fight until he can't stand
>Ash's male companion says "What's that in Charizard's hand?"
>Charizard then roars fiercely
>He mega evolves, and proceeds to destroy the rival's equally smug pokemon
>Rival admits defeat, and says that Charizard cannot win with Ash if he did not MegaEvolve.
>Charizard roars angrily at the Rival. Images flash by from when Ash saved him as a Charmander, all the way up to defeating Articuno.
>Rival's pokemon hears Charizard, motions for Rival to chill out
>Rival walks away with a dick-sucking face of failure, Rival's pokemon looking at Charizard with an appraising smile.
Then Charizard becomes too pro and wants to push himself too much without using the stone to megaevolve.
