Hyakujuu Sentai Gaoranger vs. Super Sentai

The Gaorangers start off by fighting the Demon Tribe Org until a great monster named Rakushasa has awaken from his hibernation. He is nothing like what the Gaorangers have ever fought before, as he's stronger and deadly than the other monsters they have fought before. Upon retreating the Gaorangers seem to have lost hope when they encountered a mysterious monk who tells them about the Sentai Rangers that have fought before they became Sentai Rangers. They were baffled about there being other rangers besides them. Right until their G-Phones started to move on their own each of their G-Phones lead them to the whereabouts of an different ex-sentai ranger of a different team. Each of these rangers teach them what it takes to be a Sentai Ranger. Will these ex-rangers be able to help the Gaorangers defeat Rakushasa? And who is the mysterious monk who knows all about the Sentai Rangers of the past?
