Cerberus Voyager (Japanese: ケルベロスボイジャー, Kerberos Voyager) is a Kyu Voyager from Uchu Sentai Kyuranger (2017). Unlike the other Voyagers, it is not assigned to any individual Kyuranger as a personal mecha – it is the only Voyager without an associated Ranger and is instead summoned by the mysterious Cerberus Kyutama. It belongs to the theatrical/movie context of the series and carries the nickname "Cosmic God of Destruction Kerberos." Visually it is a three-headed dog in a teal/dark-green finish, its three heads modeled after a Doberman, a husky and a bulldog; the design references the mythological hellhound Cerberus and the now-obsolete constellation Cerberus, making it the first Sentai mecha built around that theme. Collectors should note that Cerberus Voyager was not adapted for Power Rangers Cosmic Fury and was never released as a Power Rangers toy – it is Japan-exclusive.

Cerberus Voyager forms the core of its own combination called Kerberios (also spelled Cerberios). In the default formation, Kajiki Voyager serves as the right arm, Chameleon Voyager as the left arm, Oushi Voyager as the right leg and Hebitsukai Voyager as the left leg. Because Cerberus Voyager is technically a retool of Shishi Voyager – the core Voyager of Kyuren-Oh – it uses the same connection ports and mixes freely with the rest of the Voyager system. Its finisher has Kerberios charge straight into the enemy (Cerberios Final Break), and within the story the combination can grow to enormous size when suitably powered up.

The toy was released as "Kyutama Gattai 111 DX Cerberus Voyager" by Bandai (Japan), launching on 5 August 2017 at a suggested retail price of roughly 5,500 yen. The set includes the Voyager itself plus its Cerberus Kyutama. Mechanically the figure is a remold/repaint of Shishi Voyager: recolored teal and fitted with three new dog heads while retaining the Kyutama and sound gimmick of the core Voyager (battery-operated, AAA). Construction is predominantly plastic (ABS/PVC) with no notable die-cast content. Thanks to the standardized connectors, Cerberus Voyager combines readily with the regular Kyuren-Oh Voyagers. No Power Rangers version (Bandai America or Hasbro) exists.
