Windus is BC's Ventus Betadron, member of the Hurricanian Squad and a savage Bakugan in Bakugan: Wind Tamer. His Mechtogan is Dr. Wind, His Battle Suit is a Ventus Combustoid and his Mobile Assault is a Ventus Koptorix. Windus also combines with a Pyrus Kodokor and Pyrus Mutabrid (one episode only) and later Mag and Superman to form Baku-Cool's Gliderak. His new MechFrame is called Malice. Windus's full name is Windus Zeta Aireal.
Windus loves soaring to extreme heights, wreaking havoc as one of the most dangerous Baku Sky Raiders. His perfected wings and body structure can fly fast and dodge attacks. Windus also loves to bring out surprise attacks on his most despised enemies such as Silent Contestir and Mechtavius Destroyer. Windus has an army-green color, giving him a distinct advantage in the forest.
Windus has a violent temper, easily lashing out at even Pyrus Spatterix. Windus has an extreme loathing for Ventus Killer and will go out of his way to backfire Killer's plans due to a protective side for fellow Ventus Bakugan. Windus is so strong, he can even defeat the whoop-assing Dharako in a single hit, enjoying to see her plight.
Windus debuts in Hurricanian Squad, attacking BC and co. for no reason. Splice, Tex, and Core all battle Windus, only to get badly damaged in a single hit. Windus then takes Tex and Core out before they even activate their first Ability Card, with Splice lunging at Windus with a new Fusion Ability Card called Hurricanos Spore. Windus admits defeat, joining them to defeat Ventus Killer.
