Rinto's Gallade watched the battle between
Ash's Farfetch'd and
Dozer's Gurdurr at the Rock Tunnel in the Kanto region.
Rinto challenged
Ash's Farfetch'd to a battle right after it had defeated
Dozer's Gurdurr and his Gallade knocked it out with one attack. Gallade was able to avoid all of
Ash's Farfetch'd's attacks.
During the rematch battle between
Ash's Farfetch'd, Gallade let its guard down near the end of the battle to activate its Justified Ability. By taking damage from a Dark-type move like
Ash's Farfetch'd's Night Slash, Gallade revealed a strong sense of justice and increases its attack power. It wasn't enough to defeat Ash's Sirfetch'd which had just evolved.
