|This article is about a/an episode in Hyakujuu Sentai Gaoranger.|
The Lion, Roars!! (獅子、吼える!! Shishi, Hoeru!!) is the first episode and season premiere of Hyakujuu Sentai Gaoranger. It is the first episode of Gaoranger's opening arc.
A veterinarian adept at communicating with the hearts of animals is chosen by Gao Lion to lead the team of Gaorangers; warriors selected by their respective power animals to defend the earth from the villainous Orgs.
When the current Gaoranger team failed to catch an Org, it was decided that they needed a fifth member. A veterinarian named Kakeru was chosen by Gao Lion to become Gao Red. After the Gaorangers’ mentor, Tetom, gave Kakeru (now simply called “Red”) his G-Phone, the heroes responded to an Org threat.
The Gaoranger transformed and then confronted both Turbine Org and Plugma Org. The quintet combined their weapons to create the Evil Crushing Hundred Beast Sword. Once Plugma Org was killed, Duke Org's Yabaiba and Tsuetsue showed up. Tsuetsue turned the remaining beast into a giant.
To summon the Power Animals, the Gaoranger placed their Gao Jewels into the Beast King Swords. Finally, Turbine Org was defeated by a collection of energy beams from each Power Animal.
