When Funimation Entertainment acquired the license to release Fairy Tail in North America, Mashima worried about actor Todd Haberkorn's voice since the Natsu character did a lot of yelling throughout the series. Tyler Walker, the voice director for Funimation's adaptation, revealed that there was a "Fairy Tail tea" that the voice actors drank after each recording session to protect their voices. Walker likens Fairy Tail to the Scooby-Doo franchise: "it's got a core group of characters, with one talking animal, sometimes two. . . they travel, it's episodic. . . you know, we've seen this kind of thing before with the core group that's affiliated in some way going through adventure after adventure".
