Giant, who was teamed up with a female trainer, used Koffing against Dawn's Piplup and Conway's Slowking in the Hearthome Tag Battle contest. Koffing used Sludge Wave while the trainer's Scyther used Razor Wind but Slowking blocked Sludge Wave by using Safeguard. Koffing then proceeded to use Thunderbolt but that attack was negated by Slowking's Protect. After Scyther was defeated by Piplup's Peck, Koffing used Gyro Ball but the attack was stopped by Slowking's Psychic, which also defeated Koffing.
