Ash Ketchum Finally Becomes World Champion; Get a Pokemoné infected to win.

Ash's biggest moment was when he became the youngest trainer in the Japanese cartoon, Pokemon.

During the last episode of Pokémon Ultimate Journey's: The Series, Ash's Pikachu defeated Leon's Charizard.

It was the grand final between the two Pokémon in the Pokémon World Coronation Series Masters Eight Tournament.

Ash originally left Pallet to pursue his childhood goal of becoming the world's best Pokemon trainer, and after twenty years of journeying, he has finally achieved things he wanted.

In past decades, Ash's luck was not as abundant as he has ever won every competition. So far, he ranks only at the top sixteen on the list of trainers.

The final battle between Pikachu and Charizard lasted multiple episodes of "Pokemon Ultimate Series."

The official Twitter page of the series thanked Ash by writing, "He's done it! Ash has become a World Champion."
