This is a tricky question! Throughout Ash's journey, many of his Pokémon have faced tough battles and experienced both victory and defeat. However, there is one Pokémon that stands out as having an undefeated record: Pikachu.
While Pikachu has definitely been challenged and pushed to its limits, it has never officially lost a battle in the anime. This is a testament to Pikachu's strength, resilience, and the close bond it shares with Ash.
Though Pikachu has faced some close calls and even been knocked unconscious, it has always managed to pull through and emerge victorious in the end. This consistency makes Pikachu a truly unique and beloved character in the Pokémon world.
