Sawk was first used during the Club Battle tournament in where he battled against Iris's Emolga. Sawk proved a troublesome opponent for Emolga, as he could use his Close Combat to block Emolga's Attract. Stephan had stated that since Sawk is a all male species, he trained him specifically to defend himself against gender based attacks. However, when attacking Emolga, her Static ability kicked in, paralyzing Sawk. When Emolga launched a barrage of Attracts, Sawk was forced to block them all with Close Combat, lowering his defenses gradually. Eventually, Sawk's paralysis rendered him immobile, allowing Emolga to defeat him with a single Volt Switch.
In BW069, Stephan entered a competition for the Bell of Wishes Festival and chose Sawk as his partner. His Trainer attempted to take his belt from him for the scavenger hunt portion of the contest as the item he needed was a Black Belt. However, he did not give it up so easily. Later, he cosplayed as Nurse Joy's Audino for the dress-up portion of the contest which helped the two get through to the next portion. During the final portion, he helped deflect the attacks of the Pokémon trying to blow out Stephan's Litwick candle as the two climbed Mistralton Tower. Thanks to their teamwork, and a little help from Litwick, Stephan was able to win the contest.
