Shane, Tori and Dustin are three students at the Wind Ninja Academy. Their less than stellar performance and tardiness gets them the occasional lecture from their Sensei, Kanoi Watanabe. One day, the academy is attacked by Lothor, a banished ninja master who has returned to capture all ninja students. Shane, Tori and Dustin are the only three remaining students, and along with Sensei, who has been transformed into a guinea pig by Lothor, and his son Cam, retreat into the underground Ninja Ops. There, the three are given wind morphers, which allow them to transform into Wind Power Rangers and protect the city of Blue Bay Harbor from Lothor’s forces.
When Lothor demonstrates his ability to make his monsters grow into giants, the Rangers unleash the Ninja Zords, which could combine into the Storm Megazord and destroy monsters with its arsenal of Power Spheres, activated by special ninja power disks. Lothor again raises the stakes by sending his new allies to battle the Wind Rangers – the Thunder Rangers, Blake and Hunter, who had their own Thunder Zords. The Thunder Rangers are on a mission to destroy the Wind Rangers’ Sensei, who they believed to be responsible for their parent’s death, but a visit from the afterlife from Blake and Hunter’s parents show them the truth – that it was Lothor who killed them, not Sensei. The Thunder Rangers see the error of their ways and join the Wind Rangers in the battle against Lothor, bringing the Thunder and Ninja Zords together to form the Thunderstorm Megazord…
