Wingo

Iris is the main antagonist in Captain Toad: Treasure Tracker. According to game director Shinya Hiratake, Wingo was based upon both crows, a species of bird stereotypically and incorrectly depicted as interested in shiny objects, and the giant bird Roc from One Thousand and One Nights (more popularly known as Arabian Nights). He is first seen stealing a Power Star from Captain Toad and Toadette, Wingo flies away while Toadette holds on to the star, thus capturing her.

History
Wingo first appears in the opening level of Episode 1, where he ambushes the two Toads as they approach a Power Star, and after which claims it for himself. Captain Toad is stunned at the attack, while Toadette grabs on to the star to attempt to reclaim it. Wingo, however, makes off with the star, claiming Toadette in the process.

Wingo Iris does not reappear until the end of Blizzard on the Star Express (save for a few cameos in interstitial stages). Here he abducts Captain Toad and drags him off to Wingo's Watchtower, dropping him in front of the tower at the beginning of the stage. During the level, Wingo teleports around the stage and flaps his wings to create gusts of wind to blow Toad off the stage. At the end of the stage, Captain Toad fires off to the top of the tower via a Clear Pipe cannon, and battles Wingo there. During this battle, Wingo once again teleports around, attacking by blowing gusts of wind and summoning giant turnips that fall from above and can damage Captain Toad if they hit him. Wingo can be attacked by throwing the giant turnips at him, and once he is hit three times he is defeated.

Wingo reappears at the start of Episode 2. She appears like before, taking a Power Star from Captain Toad and Toadette, though this time she abducts Captain Toad, leaving Toadette to journey after him. Unlike in Episode 1, Wingo does not manually bring Toadette to his tower, but waits there for her to eventually arrive. At the end of the stage, Toadette rescues Captain Toad, though Wingo then appears and abducts Toadette once again, blowing Captain Toad off the tower.

At the beginning of Episode 3, Captain Toad finds another Power Star in a cave, only for Wingo to appear and steal it once again. While he is flying away, however, he drops Toadette. Wingo appears again at the end of Scalding Scaffold Sinkhole, where he once again captures Toadette and brings her to his tower once again, though this time Captain Toad pursues him to the tower. Wingo behaves like he does during the Episode 1 battle, teleporting and blowing gusts of wind, and at the end of the stage Wingo is once again fought at the top of the tower. His attacks are the same, though this time he also summons lightning to appear when summoning the giant turnips, and he is also defeated like before. During the end credits, Wingo once again appears, though in his fat form after eating a turnip when defeated; he tries flying away, but cannot and starts falling.

Trivia
