Behind the scenes
Ken Ashihara is portrayed by Masayuki Deai (出合 正幸 Deai Masayuki). He previously portrayed Eiji Takaoka/Bouken Silver in GoGo Sentai Boukenger. In Kamen Rider W Returns: Kamen Rider Eternal, Ken said "Good job" with a thumbs up, which is a nod to Boukengers's signification. As the Trigger Dopant, his suit actor is Norihito Itō (伊藤 教人 Itō Norihito).
- His line before turning into a Dopant is the same as what would be Nico Saiba's pre-transformation line.
