The Kamen Rider worlds become overrun with Shocker troopers as the people try to run from the chaos. The Kamen Riders try to fight back in each world but they are surrounded by the ships and tanks even with their abilities. Shocker dispatches their commanders Bat, Scorpio, Arachnio, and Mantis to aid the army. In Kuuga's world he is about to be killed by a commandroid until a familiar cutlass cuts in to save him.
"Marvelous, is that..."
"Save it. You're way over your head. Guys let's go."
The other pirates show up to help Kuuga and evacuate the civilians. They use several Ranger keys to disperse their enemies.
"Time to change things up guys!"
"Right!"
"Shift Into Turbo!"
"Lightspeed Rescue!"
"Time For Time Force!"
"RPM Get in Gear!"
"Magical Source, Mystic Force!"
"Let's rocket!"
"Jungle Fury, spirit unleashed!"
Marvelous becomes the red Turbo Ranger, Skipper becomes the blue Lightspeed Ranger, Davy becomes the green Time Force Ranger, Cerina becomes the yellow RPM Ranger, Lana becomes the pink Mystic Force Ranger, Dutch becomes the silver Space Ranger and Sirius becomes the Black Jungle Fury Bat Ranger.
"Skip, we need to find April! She's being attacked by the commandroids!"
"Right, Davy, give us a diversion!"
"Roger that! V blaster!"
Davy uses the V blaster to distract the commandroids as the two head out to find April. Marvelous speeds up and finishes off several of the commandroids. Cerina uses her spells to make the other commandroids fly in the air before Dutch uses his Super Silverizer to blast them down. Sirius uses his flight to take down several more droids and Davy uses his time speed abilities to destroy the rest of them. Skip and Kuuga find April pinned down but One and Two show up to help her.
"April, go with your mom you'll be safe!"
April heads out and encounter the two Riders.
"Who are you?"
"We're friends. We have dispatched across the other worlds to stop Shocker. We have to keep them at bay."
"Yeah, we will. They got Decode didn't they?"
"Yes, but it's not too late to save him."
"Leave him to me."
"Let's go save your world then."
One, Two, Kuuga, and Skip return to the battle where they find the Rangers quickly finishing off the rest of the droids. Suddenly Nyongo's remaining forces return to finish them off and they prepare for battle. Kuuga transforms into his Rising Ultimate form and rushes towards them.
"You heard the man, let's finish them off."
"Sky Raider power!"
The Rangers transform into their super Ranger forms. Marvelous becomes the Time Force Red Warrior Ranger, Skip becomes the blue SPD SWAT Ranger, Davy becomes the green Shogun Samurai Ranger, Cerina becomes the yellow Celestial Guardian Angel Ranger, Lana becomes the pink Mystic Legend Ranger, Dutch becomes the Mega Battle Quantum Ranger and Sirius becomes the Red Wild Force Animarium Ranger. Together with One and Two they manage to finish them off and prepare for a final attack.
"Sky Raider ultimate final strike!"
"One!"
"Two!"
"Rider kick!"
