After Masato failed to confront Don Bugdez on his own, Mighty ran away, leaving Masato behind. Mighty and Wanda are companions, especially when they get separated by mistake, even later on when Mighty decides to help Yuto, Mirai, and Shuu get rid of Don Bugdez with their Kamiwaza teammates Wanda, Nice, and Amazing by using the Fact-Promins and restoring the Wonder-Star using Wonder-Promin.
