Cube Kuma (Japanese: Cube Bear) is one of the auxiliary mecha from Doubutsu Sentai Zyuohger (2016), the season built entirely around an animal-and-cube robot concept. Because Zyuohger was never adapted into a Power Rangers series, Cube Kuma exists only as a Japanese Bandai toy and was never released under a Power Rangers or US name. Within the show it is one of the fourteen Zyuoh Cubes and does not belong to the five-piece core combination team; instead it sits among the supporting cube animals that double as add-on mecha and weapons. Its underlying animal motif is a brown bear.

Like the rest of the line, Cube Kuma works on a modular building-block principle. From its compact cube form it unfolds in a few steps into animal (bear) mode, and from there into a battle axe known as the Kuma Axe. In this weapon mode it is wielded by the main combination Wild ZyuohKing to perform the Kuma Axe Zyuoh Impact finisher, a heavy cleaving strike. Cube Kuma also serves as a component of the larger gattai forms, contributing limb sections to expanded combinations such as Wild Tousai King and the ultimate all-in-one union, Wild Tousai Dodeka King.

The DX toy was produced by Bandai (Japan) and released in May 2016 at a list price of roughly 1,000 yen. It is an all-plastic model with no die-cast content, in keeping with the line's deliberately simple, blocky system design. Transformation is handled through a small number of folds (cube to bear to axe, including a flip-out handle). The axe form can be stored along the sides of Wild ZyuohKing's legs or plugged onto the shoulder pegs of Cube Gorilla or Cube Eagle. One collector note: the slim handle is not gripped fully when mounted on the gorilla arm and can lean forward, taking on a slight permanent bend over time. No Power Rangers version of this zord was ever manufactured.
