Cam is in need of the data disc for the Tsunami Cycles, which Dustin had last, all unaware that it's not only landed in the hands of the evil Thunder Rangers, but has been used to give them their own Cycles! This leads to the first confrontation between the Wind and Thunder Rangers, and as if our heroes didn't have it bad enough, they also face Zurgane! When the Thunder Rangers unveil their own Zords, can our heroes' own Zords withstand their awesome power?
I Thunder Rangers entrano in possesso di un disco di Cam e riescono ad anticipare ogni mossa dei Wind Rangers.
Thunder Rangerne bruger deres Tsunami-cykler og Thunder Megazord til at kæmpe mod Wind Rangerne.
Les Rangers Tonnerre se décident finalement à attaquer. Ils battent les Rangers Cyclone grâce à leurs propres Diablo Cyles et Zords. Lorsque Blake est blessé en voulant protéger Tori, elle l'emmène au Quartier Général. Maintenant qu'ils connaissent leur cachette, les Rangers Tonnerre l'infiltrent et kidnappent le Sensei, l'accusant d'avoir tué leurs parents. Les Rangers Tonnerre apprennent ensuite que le meurtrier est Lothor, et ils quittent son rang.
