Cube Hyou (キューブヒョウ, "Cube Leopard") is an auxiliary mecha from Doubutsu Sentai Zyuohger (2016), the 40th Super Sentai series. The Zyuohger heroes pilot cube-shaped mecha called Zyuoh Cubes, which unfold from a compact cube into an animal form and dock together into larger robots. Cube Hyou is a yellow support cube modelled on a leopard. Unlike the six core "King's Credential" cubes, which are numbered, it bears an exclamation point (!) to mark it as an extra cube rather than one of the numbered main cubes, and it is not tied to any single Ranger — it functions as a universal add-on Zord. Because Zyuohger was never adapted into a Power Rangers series, Cube Hyou was never released as a Power Rangers toy; it is Japan-exclusive and has no US name.

Like every Zyuoh Cube, it has three modes: a compact cube, an animal form (leopard) and a weapon form. In weapon mode it becomes the Hyou Hammer (Leopard Hammer), which the lead mecha ZyuohKing can wield, the cube attaching as arm armament. It belongs to the "Animal Armament" (Doubutsu Busou, 動物武装) accessory line, designed to plug onto the show's DX robots such as (Wild) ZyuohKing. Structurally it is a redeco/remould of Cube Kuma, the bear cube, sharing most of that toy's construction and folding gimmick.

The DX toy was produced by Bandai Japan and released on 27 August 2016 — not on its own but as a two-piece set, "Zyuoh Cube Weapon EX – Animal Armament: Cube Hyou & Cube Fukurou (Owl) Set" (around 1,980 yen). The set contains Cube Hyou (leopard, forming the Hyou Hammer) and the owl-shaped Cube Fukurou (forming the Owl Cutter). Both are small, mainly plastic folding cubes with the line's standard three-mode transformation (cube/animal/weapon); no die-cast content is documented for this accessory cube. As a weapon/add-on set, Cube Hyou is one of the optional Zyuohger line extensions rather than a core combining robot.
