In The Legend of Thunder!, Marina used Wani-Wani to battle Jimmy's Beedrill after Pink was defeated. Jimmy then called Beedrill back and used his Typhlosion to battle against the Water-type Pokémon. During the battle, Marina was shown to be in sync with Wani-Wani's actions. Despite the type-disadvantage, Typhlosion managed to stand up to Wani-Wani's attacks.
Despite Wani-Wani's brief appearance in The Legend of Thunder!, it was shown to be in sync with its Trainer and was able to hold its own during battle. After it evolved sometime before A Stand-Up Sit-Down!, Wani-Wani was also shown to have good performing skills as Marina was able to earn the title of Top Coordinator.
