ToQger vs. Kyoryuger will see the twelve rangers from both teams join forces to fight against an evil super giant. They must also save the Galaxy Line, which is falling from space. To make matters worse, the five main ToQgers are turned into children by a Shadow Monster.

The year is 2025, 10 years after the fight against Z. The ToQgers are all grown up and have now entered life. But one day, the Shadow Line reappears and the fight must resume. Right and his friends try to repel them but they can’t transform because they lack imagination. Fortunately for them, a mysterious purple warrior appears to save them. Will they be able to defeat the Evil Army Shadow Line once and for all? Will they find the ultimate imagination?

The Ninningers come across a new enemy, Dark Doctor Mavro, a remnant of the Shadow Line, who created his own, evil version of Aka Ninger serving under him by stealing the real Aka Ninger's Nintality, and because of it, Takaharu's life is now in danger. All hope seems lost until the Ninningers meet the ToQgers, who fought and defeated the Shadow Line in the past, and it's up to them to join forces in order to overcome this new crisis.
