Geki Wolf (ゲキウルフ) is the personal Geki Beast of Gou Fukami – GekiViolet, the mysterious fourth warrior of the Gekirangers and a master of the Fierce Beast Wolf-Fist. The silver-and-violet wolf is summoned through the GongChanger, a wolf-shaped morpher built specifically for Gou. On its own, Geki Wolf fights with leaping and biting attacks plus a bladed tail-tip, using a rolling somersault to slash straight through its enemies.

Its signature moment is the fusion with GekiTohja: Geki Wolf replaces GekiCheetah as the right leg to form GekiTohja Wolf. This configuration is a pure kick-fighter – a blade sits in the knee, and its finisher, the "Great Wolf-Wolf Leg," roundhouse-kicks the wolf's tail so it sails through the air like a boomerang to slice the opponent apart. It gives the team a completely different combat profile from the fast Cheetah legs of the standard robo.

The DX toy was released by Bandai (Japan) as "Juken Gattai Series 04 – GekiWolf." The wolf folds and locks from its four-legged beast mode into the leg module and clips straight onto the DX GekiTohja, letting collectors recreate GekiTohja Wolf exactly – tail-throwing gimmick and all. In North America the show aired as Power Rangers Jungle Fury under Bandai America, but the Wolf zords there were sold in a smaller, simplified scale; the full DX release remains the Japanese one.

In Power Rangers Jungle Fury the wolf spirit belongs to RJ (Robert James), the Violet Wolf Ranger. His Wolf Animal Spirit likewise forms the right leg of the Jungle Pride Megazord to create the Wolf Pride Megazord, whose finisher "Spin Fury" fires the leg blade through the wolf's mouth. A nice collector footnote: the Bat Animal Spirit can be mounted as chest armor, letting the Megazord spin like a fan blade.
