Wulfric is the Gym Leader of Snowbelle City's Gym, known officially as the Snowbelle Gym. He specializes in Ice-type Pokémon. He gives the Iceberg Badge to Trainers who defeat him.

Wulfric appears in Pokémon X and Y as a Gym Leader. Trainers who defeat Wulfric will receive the Iceberg Badge, along with TM13 (Ice Beam). He is said not just to be a strong Gym Leader but also very kind to Pokémon, which is why Pokémon, such as those in Pokémon Village, admire him.

Initially, Wulfric is not at the Snowbelle Gym, instead being said to be at the Winding Woods. Indeed, Wulfric is found at the Pokémon Village, a location west of the woods, where he explains the place to the player. From there, he goes back to his gym, which is now able to be challenged.

According to the television show Gym Freaks, Wulfric is a fan of the Brycen-Man Series, to the point of crying when watching the latest movie. He is also rumored to keep a photo of his dearest Pokémon in the locket he wears around his neck.

Wulfric made his debut appearance in All Hail the Ice Battlefield!, in which Ash battled him in an attempt to earn his eighth Kalos Gym Badge. Despite only using two Pokémon to battle Ash's three, Wulfric emerged victorious. Wulfric then explained that Ash is not having enough trust in his bond with Greninja, which left the latter in serious doubt.

Wulfric reappeared in A Real Icebreaker!, where Ash, having gotten over his depression, challenged him to a rematch. This time, Ash put up a much better fight, eventually leading both sides with one Pokémon each: Ash's Greninja standing up against Wulfric's Abomasnow. With its now-perfected Ash-Greninja form, Greninja was easily able to gain an upper hand in the battle. However, Wulfric then suddenly Mega Evolved his Abomasnow, giving it a massive power boost. Despite this, Ash was eventually able to win the battle, earning him the Iceberg Badge.

He appeared in a fantasy in A League of His Own!, when Ash was talking to Everett about the Gym Leaders that he had defeated in Kalos, in order for him to be able to compete in the Lumiose Conference.

He appeared in XY132, where he was in the Winding Woods, watching Lysandre's broadcast from Lumiose City while being surrounded by some wild Pokémon in the forest.

He appeared again in XY135 and XY136, where he helped to destroy the Megalith Zygarde.
