A girl named Rita who hosts the Super Sentai Strongest Battle once in 500 years. The person who wins gets his wish fulfilled.
Super Sentai will be battling each other based on Team. Like Zyuoh Eagle, Gao Red, Vul Shark & Ginga Green will be fighting based on Air-Land-Water abilities. Go-On Red will be fighting Aka Ninger as warriors who rides something & more.
By thinking of this, it is just Ultra Super Hero Taisen with only Sentai Teams.
Gaisorg will appear in front of Super Sentai and attack them for some reason. He is consider to be the strongest in Space.
Captain Marvelous will fight him.
Ryusoulgers are seen in the battle in few scans.
