Aegislash first appeared as a Honedge in A Meeting of Two Journeys! where it was the second Pokémon Sawyer used in his battle against Ash. It battled against his Pikachu but was easily defeated by Pikachu's Thunderbolt.
Sometime before A Full-Strength Battle Surprise!, Honedge evolved into Doublade. During Sawyer's battle against Ash, it was the first Pokémon sent out. It went up against Noivern. Even though it put up a long fight and stayed in the battle longer than when it was a Honedge, Doublade was defeated by Noivern.
In Valuable Experience for All!, it was revealed to have evolved in Aegislash. Sawyer used it in his match against Tierno in the Lumiose Conference. It fought against Ludicolo first and won but ended up getting defeated by Raichu.
In Analysis Versus Passion!, it had a rematch with Ash's Pikachu, Pikachu tried to attack Aegislash from a distance by hiding in the trees on the battle field, Sawyer then commands Aegislash to use Sacred Sword and cut down all the trees and Aegislash succeeds. The battle continued in A Riveting Rivalry!, where it ended up getting defeated by Pikachu.
It appeared again in Till We Compete Again!, during a flashback.
