Cube Fukurou (Owl) is an auxiliary Zyuoh Cube from the Japanese series Doubutsu Sentai Zyuohger (2016), the season marking the 40th Super Sentai anniversary. Zyuohger was never adapted into a Power Rangers series, so this unit was released only in Japan and never appeared as a Power Rangers toy. Within the show it is part of the wider Zyuoh Cube arsenal used by the Zyuohger team led by Zyuoh Eagle (Yamato Kazakiri) rather than a core cube tied to a single Ranger. Rendered in green and shaped like an owl, it is a redesign/redeco of Cube Komori (bat). A printed exclamation mark identifies it as a cube that is not one of the six royal main cubes ("King's Credentials"), i.e. an auxiliary or weapon cube.

Like all Zyuohger mecha, Cube Fukurou is a "Cube Animal" that folds between a compact cube shape and its animal (owl) form. Beyond that it converts into the "Fukurou Cutter", a bladed weapon that ZyuohKing can wield in any of its combined configurations to deliver a finisher. As a support cube its purpose is therefore to arm the existing robot combinations rather than to form a robot of its own. In the series it was also one of the many cubes that contributed to the giant Wild Tousai King formation and its "Zyuoh Dodeka Dynamite Stream" finishing move.

The toy was made by Bandai Japan and released in 2016 as part of the "Zyuoh Cube Weapon EX" line (Doubutsu Busou / Animal Armament). Rather than being sold on its own, Cube Fukurou came bundled in the "Cube Leopard & Cube Owl" set together with Cube Leopard. It is a small, all-plastic item with no significant die-cast content; its play feature is limited to folding from cube to animal to weapon form, which then attaches to the DX robots. Because it reuses the Cube Komori tooling, it is essentially a recolored, lightly altered variant within the weapon-cube series, and like the entire Zyuohger line it remained a Japan-exclusive release.
