The Hundred Beasts Roar!! (百獣、吼える!! Hyakujū, Hoeru!!) is the fifty-first and final episode of Hyakujuu Sentai Gaoranger. it is the conclusion of Gaoranger's four-episode endgame.
With the city turned to chaos as Senki fulfills his ultimate goal, the rangers, powerless, march on and prepare to face Senki with help coming from the last place they'd ever expect.
The Power Animals have been destroyed and Sky Island heading for a crash landing. In the city, Orgettes sweep the streets, causing havoc. Even without their powers of Power Animals, the Gaorangers go on fighting, making their way to the top of a tall building to take on Senki himself. GaoRed manages to stab Senki in the heart, but to no avail. The Gaorangers formally introduce themselves to each other for the first time just as the heavens open, allowing all 100 Power Animals to return to Earth to attack Senki. The Gaorangers are introduced to GaoMouse, GaoStingray, GaoHorse, and GaoPeacock, before their own Animals return to them, allowing the Gaorangers to transform one last time. The Gaorangers and Power Animals destroy Senki with an Animal Heart attack, then the Gaorangers use the Hyakujuuken to finish the job by destroying Senki's heart. The Power Animals then return to the sky. As a result of the death of the last Org leader, The Matrix sinks and collapses, destroying itself while killing TsueTsue and Yabaiba inside. Later, Tetomu tells the Gaorangers that she must return to her sleep in case the Orgs return in the future. The Gaorangers return their jackets and G-Phones to Tetomu, who thanks them for their efforts, then returns to Sky Island. The Gaorangers go back to their lives - Gaku in the air force, Sae at her father's dojo, Soutarou on a farm, Kai as a lifeguard and Kakeru as a vet. Tsukumaro goes traveling the world.
