Mac Windy

"Warrior of Wind - B-Figher Yanma!"

Mac Windy/B-Fighter Yanma (マック・ウィンディ／ビーファイターヤンマ, Makku Windi/Bī Faitā Yanma) : Mac was from the New York office, a master of boxing and aikido chosen by the Dragonfly Insect Medal to become Yanma. He posed as an exchange student in Kouhei's school, becoming the boy's rival as a result. He eventually revealed himself as a B-Fighter when the three were attacked by B-Crushers, making a enemy out of Mukadelinger and losing to him until Kabuto comes to his aid.

After giving him his Tonbou Gun, Mac left for America after telling them of the three other Insect Medals. Mac was outgoing, flirting with Japanese girls at every chance and pigging out on sushi. As Yanma, Mac's armor was modeled after a dragonfly. His attacks were the Dragon Flying (ドラゴンフライング, Doragon Furaingu) spin attack, and the Spinning Bomber (スピニングボンバー, Supiningu Bonbā), a tornado spin attack.
