Denji Sentai Megaranger vs. Carranger

The V-Cinema special takes place between episodes 39 and 40. Arriving late for school, as the car was at Pegasus Garage, Kenta learns that today is graduation picture day. Seeing a beam of light nearby, Kouichiro gets the others out of class to investigate. The five find a seashell before they are attacked by Space Biker Helmedor who wants the shell to fulfill his dreams, overpowering the Megarangers before Mega Silver arrives and engages the biker in a motorcyclists' duel. Suddenly enlarging with his bike, Helmedor battles Super Galaxy Mega before he is forced to shrink and retreat. Later, while trying to find out the seashell's true nature, Miku uses it to wish for a big cake before it is stolen by a group of strange students who actually are the staff of the Pegasus Garage. But with Mega Yellow placing a tracer on the getaway car, the Megarangers track them to the Pegasus Garage where Kyousuke wishes for Katsudon before he and his team are attacked by Yugande and Kani Nejilar. Refusing to stand aside, they assume their Carranger forms to fight Kani Nejilar while the Megarangers deal with Yugande and the Kunekune. The two Sentai teams join forces to force the Nejireians back as the shell opens up to reveal an alien identified as Space Fairy Picot who wants to grant their last three wishes. Arriving to Yume Beach, the teams get to know each other while talking out to want they would use the last three wishes before Dappu arrives. But "Dappu" turns out to be Helmedor, having made a deal with the Nejirians to get Picot.
As Helmedor runs off, Shibonlena has the Kunekune hold the Megarangers as she uses her power to turn the Carrangers into her slaves and sicks them on the Megarangers. During the fight, the Megarangers find the real Dappu and untie him. In a risky gambit, Dappuin fuses the Megrangers's weapons with his CarMagic to free the Carrangers from Shibolena's spell. At that time, after wishing for a planet destroying laser cannon, Helmedor betrays Kani Nejilar and fights him as Megarangers. After making a wish to revive previous Psycho Nejilars to overpower the Megarangers, Kani Nejilar was about to make the final wish when Helmondo steals the fairy. But the Carrangers get Picot and throw a decoy into the distance to hold the villains at bay. Coming to the students' aid, the Carrangers give them Picot to make the final wish to their shock. By the time Kani Nejilar and a brainwashed Helmondo return to the battlefield, the Megarangers' wish to keep fighting enables them to don the Mega Tector armor. After destroying the revived monsters with Rainbow Impulse, Shibolena has Bedibedi bite Kani Nejilar and Helmedor as Mega Voyager and RV Robo are formed to fight them. Though Helmondo attempts to turn with the planting destroying laser, Mega Winger destroys the weapon as Wing Mega Voyager and RV Robo execute their signature moves to respectively destroy Kani Nejilar and Helmedor. Soon after, Picot leaves for the next planet as the two sentai teams go out to take their own graduation memorial picture at Yume Beach.
