The Zenryoku Zenkai Cannon (Japanese 全力ゼンカイキャノン / ゼンリョクゼンカイキャノン, Zenryoku Zenkai Kyanon) is from the Super Sentai series Kikai Sentai Zenkaiger (2021), the 45th-anniversary season that draws on the powers of every past Super Sentai team (the "Legend Sentai"). It serves as the auxiliary weapon and personal support mecha of team leader Zenkaiser and his upgraded form Super Zenkaiser, storing the combined power of the Legend Sentai. Because Zenkaiger never received a Power Rangers adaptation, this item exists solely as a Japanese DX toy and was never released as Power Rangers merchandise (Japan-exclusive).

Within the show the Zenryoku Zenkai Cannon has three roles. In cannon/weapon mode it is a handheld arm whose rotating chest gear triggers the special and finishing attacks of the legendary teams. It transforms into the fighter-jet mode "Zenryoku Eagle" (全力イーグル), which Zenkaiser flies and fires. Finally it forms the core of the large robot combination "Zenryoku Zenkai-Oh" (全力ゼンカイオー) by uniting with the Zenkaizords.

The DX toy is made by Bandai (Japan) and was released on 9 October 2021 at roughly ¥6,600 (about 32 cm in size, weighing around 960 g). It is mostly plastic with electronic sound and light features: eleven different attack and finisher sounds with matching light patterns, glowing eyes, plus jet and gunfire sounds in Eagle mode. Collector note: the Cannon on its own provides the weapon, the Eagle jet and the combination core; completing the full Zenryoku Zenkai-Oh additionally requires the separately sold DX Zenkai-Oh JuraGaon set and DX Zenkai-Oh BuruMagine set.
