Behind the Scenes


Killbas is portrayed by Gaku Shindo (進藤 学 Shindo Gaku), who is best known for his role as BarizorgIcon-crosswiki from Kaizoku Sentai GokaigerIcon-crosswiki. His voice in-suit is provided by Anri Katsu (勝 杏里 Katsu Anri). As Kamen Rider Killbas, his suit actor is unknown.


  • Killbas' spider motif finished the last part of the recurring bat/cobra/spider trio in the Kamen Rider franchise, a tribute to the first two Shocker monsters as well as the first monster to be upgraded, following Blood Stalk's cobra motif and Night Rogue's bat motif.
  • Killbas will most likely be the final movie-exclusive Kamen Rider to debut in Heisei Era considering the era ends a week after the film's release date.
  • Like previous V-Cinema Exclusive riders they are made up of parts from previous or current rider suits, his helmet used Blood Stalk, Night Rogue/MadRogue's helmet based, Blood Stalk's shoulders and gauntlets, armpit armor taken from either Blood Stalk, Night Rogue/MadRogue suit painted black, as well as some parts from the Hazard Body for the feet and shins.
  • It seems that Kamen Rider Killbas’ general design also takes cues from Kamen Rider Saver, besides what’s listed above; a primarily red color scheme and that he supposedly dual-wields a sword and a bow-and-arrow weapon in battle.
