American voice actor Daman Mills was cast as Johnny Joestar in the Netflix adaptation of JoJo's Bizarre Adventure: Steel Ball Run, adding to a resume built largely on major anime and game dub roles including Frieza in Dragon Ball Super.
Mills voices Johnny Joestar, the paralyzed former prodigy jockey at the center of Steel Ball Run, in the Netflix adaptation of the seventh part of JoJo's Bizarre Adventure, with the casting announced in February 2026. The role marks a departure from the confident, larger-than-life characters he has typically played, calling instead for a more vulnerable, restrained performance as Johnny works to regain use of his legs during a cross-country horse race.
Mills is most widely recognized for stepping into the role of Frieza in Dragon Ball Super, having understudied original English voice actor Christopher Ayres before fully assuming the part after Ayres passed away in 2021. He has also voiced Jyugo in Nanbaka, Ginshi Shirazu in Tokyo Ghoul:re, and Douglas Bullet in the film One Piece: Stampede, working professionally in anime and game dubbing since 2015.
