KyurenOh is the main mecha and lead Megazord of the 41st Super Sentai series, Uchu Sentai Kyuranger (2017). It is not tied to a single ranger; instead it is assembled from the Voyagers, the individual spacecraft-mecha of the nine Kyurangers, with Shishi Red's Shishi Voyager (constellation Leo) as the core. Its full Japanese combination name is Kyutama Gattai KyurenOh. The footage was later adapted for Power Rangers Cosmic Fury (2023, Netflix, season 30), where the robot is simply called the Cosmic Fury Megazord.

The defining feature is the Seiza Docking (constellation docking) or Kyutama Gattai system: Shishi Voyager forms the head and torso, while any four other Voyagers attach freely as the left and right arms and left and right legs, with almost every slot interchangeable. This produces a large number of possible builds. In the standard configuration, Kajiki Voyager serves as a sword arm, Chameleon Voyager as a grappling arm (its tongue acting as a wire), Oushi Voyager as a charging leg, and Ookami Voyager as a kicking leg. Because each Voyager brings its own weapons and attacks, KyurenOh's armament and finishers change with the chosen layout.

The DX toy was released by Bandai Japan in February 2017 as part of the Kyutama line. The base Kyutama Gattai DX KyurenOh set contains five Voyagers (Shishi, Ookami, Oushi, Chameleon, Kajiki) and supports 24 formations on its own; additional Voyagers (including Sasori, Tenbin, Washi, Hebitsukai and Ryu) were sold separately and considerably expand the connector system. Construction is predominantly ABS/PVC plastic with no significant die-cast, and the Kyutama spheres act as plug-in and sound gimmicks. For the U.S. market, Hasbro produced only a heavily simplified Cosmic Fury version — the Amazon-exclusive Cosmic Zord Mega Pack (Cosmic Fury Megazord, Fall 2023) using a basic Zord Link connector system and five renamed zords (Cosmic Lion, Wolf, Bull, Chameleo, Shark). The full swap-combination system remained exclusive to the Japanese DX release.
