Goggles

Aviator goggles (ゴーグル Gōguru) are a traditional symbol for the lead human protagonist of Digimon stories, who are often nicknamed "goggle boys". Almost every lead protagonist from each Digimon and Appmon anime series wears goggles (Daimon Masaru from Digimon Savers and Amanokawa Hiro from Digimon Ghost Game are the only exceptions), and so does every manga protagonist and the majority of video game protagonists. Most of the time, the goggles are purely a fashion item that they wear on the forehead and are not used by the wearer as eye protection.

Other common traits that "goggle boys" share, especially in the anime and manga, are that they are the leaders of a team of Tamers or Chosen Children, their names start with the phoneme ta (た) or da (だ), they are associated with warm colors like red and orange, and they are partnered with Digimon who are dragon- or reptile-type and/or have fire attacks. In the anime and manga, only males have worn goggles so far, and the only "goggle girls" currently appear only in video games.

Some species of Digimon and Appmon also have goggles of their own. These species are usually either heroic dragon- or reptile-type Digimon who, like "goggle boys", have goggles purely for aesthetic reasons, or they are militaristic in theme and wear their goggles for practical purposes.

Yagami Taichi wears a pair of goggles around his neck. He briefly uses them as a weapon by throwing them at Botamon while it is under the bed, to try to scare it out.

Taichi wears a pair of goggles, together with a headband, throughout the series and in Our War Game!

At the start of the series, Motomiya Daisuke wears a pair of goggles of his own in imitation of Taichi, whom he idolizes. These goggles are destroyed by an Evil Ring-possessed Monochromon in "The Inheritor of Courage", and at the end of the episode, Taichi gives Daisuke his goggles as a symbolic passing of the torch to the leader of a new generation of Chosen Children. Daisuke wears Taichi's goggles for the rest of the series.

Ichijouji Ken's Digimon Kaiser outfit also features a pair of thick tinted goggles that he wears over his eyes. He throws these goggles away when he is defeated in "Goodbye, Ken..." and they dissolve into data.

In the epilogue in "Our Digital World", Daisuke's son wears a pair of goggles which resemble Taichi and Daisuke's. At this point, neither Taichi nor Daisuke are wearing goggles.

In "Reunion", Izumi Kōshirō provides Taichi with a new set of enhanced goggles that visualize distortions, allowing him to track where Infected Digimon are about to appear. When he is not using them, Taichi usually wears these goggles around his neck instead of on his forehead.

In "Loss", when Taichi disappears in Jesmon's attack, only his goggles are left behind. Ishida Yamato begins wearing them in Taichi's place, as a symbol of how Taichi would want the group to keep going. When Taichi returns to the group in "Our Future", Yamato returns the goggles to him.

A pair of goggles are part of the Mysterious Man's Digimon Kaiser disguise. These goggles are smaller and significantly different than the original Kaiser goggles, but they are still darkly tinted.

Two flashbacks in "Loss" reveal that Nishijima Daigo also used to wear a pair of goggles when he was a child, during his adventure in the Digital World with Himekawa Maki and the other original Chosen Children. The goggles were knocked off his head in his team's final battle with the Dark Masters. He no longer wears them as an adult.

At the start of the film, Taichi wears another new set of goggles that Kōshirō has enhanced with a targeting heads-up display. However, they are still a work in progress, and an error with their display nearly causes Taichi and Agumon to be unnecessarily hit by Parrotmon, so he stops using them. Later, he gets a pair of regular goggles out of storage along with his old Digivice and starts wearing them again until after the final battle with Eosmon.

Daisuke no longer wears any goggles.

In "You are my Friend - Introducing Terriermon!", Matsuda Takato adopts a pair of goggles that he had found when he declares that he is Guilmon's Tamer, and continues to wear them for the rest of the series.

In "Burn Up, Tagiru! The Glorious Digimon Hunt", Astamon destroys Tagiru's goggles when it betrays the group. Taiki, who had been injured badly by Astamon, gives Tagiru his goggles when he asks Tagiru to fill in for him as the one to wield the Brave Snatcher.

Shinkai Haru wears a pair of goggles throughout the series. In "I Will Have You in Costume! Cameramon's Halloween Scandal!", he briefly puts them over his eyes when he tries to blend in with a crowd of people in costume to avoid detection by Cameramon, but takes them off when he realizes that there are cameras everywhere so there is no point.

Yagami Taichi wears a pair of goggles, together with a headband, throughout the series. "Goggles..." reveals that the goggles are a gift from his grandfather, who had them as a memento of a deceased pilot friend. When Taichi was young, his grandfather gave the goggles to him as a symbol of the courage to act to protect one's friends, like his pilot friend used to do, after Taichi witnessed a friend being bullied. From "Butter-fly" onward, Taichi sometimes wears these goggles over his eyes when he is flying on Zeromaru (as Aero V-dramon).
