He first appears when Jaden was searching for the other Neo-Spacians. When Domino City was covered with a huge barrier, Air Hummingbird appeared and informed Jaden that no Duel Spirits could leave the city.
Neo-Spacian Air Hummingbird appears in Yu-Gi-Oh! World Championship 2007. He appears as a Level Three Theme Duelist and he challenges the player to cause 20000 or more points of Battle Damage directly during a Duel. By beating him, the player gets closer to unlocking Level Four Theme Duelists and a new Booster Pack.
