Tenjuro Banno (蛮野 天十郎, Banno Tenjūrō) is the main antagonist of Kamen Rider Drive. He was a scientist and the co-creator of the Roidmudes alongside his former colleague, Krim Steinbelt who digitized his mind into the Transformation Belt Banno Driver (変身ベルト バンノドライバー, Henshin Beruto Banno Doraibā), allowing him to transform into Gold Drive (ゴルドドライブ, Gorudo Doraibu). Many years after his demise, Banno would be resurrected by Foundation X in a Humagear body as Bronzedrive (ブロンズドライブ, Buronzu Doraibu) as part of Project Outsiders.
