Trivia

 * Gale was a design from another mangaka back when ONE was still unemployed. That is the reason why they cannot be used in the redrawn version and instead replaced by Gale Wind.
 * It's unknown if Gale's existence is even canon to the webcomic anymore or if his existence has been retconned, as Gale Wind appears during the Ninjas Arc with no mention of Gale at all. It's also possible that the two are technically different beings in the webcomic.
