Wakfu - Season 1 Episode 6

With no other route to take, the group is forced to pass though an inhospitable town full of decay and zombie-like townsfolk. Vampyro, a vampire, comes to claim Eva as his wife, by using a magical ring to take her shadow, i.e. her soul. The group launches a rescue mission, avoiding ghouls launched by Vampyro. While scaling his castle, the group is overrun by vampire bats. Percedal volunteers to stay behind while the others go to rescue Eva. They arrive and find that Vampyro is using Eva's body as a vessel for his true love, Shadofang. Vampyro uses his shadow stealing powers on Ruel, turning him into a beast that Amalia eventually defeats. Amalia, Yugo, and Percedal fight Vampyro, but he proves to be too powerful. However, during the fight, they discover his weakness: he's allergic to Az, their mascot. the group uses Az to their advantage, overpowering Vampyro and getting the ring off of him. He turns back to his original self, a magistrate named Wagner. His release also turns the town and the townspeople back to normal and returns the shadows of Eva and Ruel.
