Wikstrom debuts in Malamar Traps. He first appears as a fantasy when Diantha informed Korrina about each of the Kalos Elite Four. He later debuts in person alongside Drasna, where he assists X and Y's group in their quest to stop Team Flare. With his Probopass's magnetic abilities, Wikstrom created guides in the road to help X's group travel to Team Flare's hiding place. Later, Wikstrom battles against members of Team Flare at Route 20.
After Team Flare is fully defeated, Wikstrom, the remaining Elite Four members, and Diantha carry the unconscious body of Malva, who had turned out to be a member of Team Flare.
Probopass is Wikstrom's only known Pokémon. It was first used to help X and his friends on their way to Team Flare's hiding place. By using its magnetism to pull ore from the ground, Probopass made guides in the road to lead X and his friends on their way.
