Ariana sent Murkrow to battle Crystal. The latter's Monlee used Mach Punch on Murkrow, who endured the attack, and retaliated against Monlee. Murkrow continued the battle, while Ariana and the rest of her Pokémon got hit by Silver's Rhyperior's Earth Power. Murkrow flew off, to which Monlee used Bullet Punch to slam it to the ground. However, Murkrow pushed Monlee to the ground, defeating it.
Murkrow was used to bind Arceus at the Sinjoh Ruins. Ariana had Murkrow battle Crystal's Chumee, to block her from interfering with their plans involving Arceus. When Arceus was attacking, Murkrow lifted Ariana into mid-air. Murkrow was still carrying Ariana, as Archer took control over Arceus.
