However, seeing Kamen Rider Magician risk his life to protect Karen and a child from their fight's collateral damage, Platinor P-Model sees the magician to be protector like himself and takes his leave. Returning to the Universal Cops Headquarter to report to his superior and the previous/original Platinor, Richard Irving that Henry Spellman is not their enemy, Rob refuses to carry out the mission to eliminate Kamen Riders Magician and Leo. In response, Richard relieves Rob from duty and gives the mission to Jack, Rubyor, with Rob unable to convince his senior to let him investigate further. Elsewhere, with her Beast Vanguard teammates unable to meet up with them at the campsite, Nicole and her partner Cottonball notice a strange object crash landing nearby. The two manage to reach the impact site and find a small robot that Nicole brings to the Grand Bureau.

With Arlo coming to help him return to their dimension after a brush in with the Vehicle Warriors, Rob rescues Nicole and Mindrolly from Universal BioBorg Empire troops with help from Leo.
Taking refuge at the Antique Shop with the others, Arlo reveals the existence of Evil Magic Kingdom to present company with Rob seeing that the only recourse for the Universal Cops Headquarter to save the universe is to wipe out Earth with the Super Dimensional Cannon. But with Arlo telling him that such an option is unacceptable, Rob leaves to meet with Jack who tells him that they are too late to stop Evil Magic Kingdom from bringing the fortress to Earth and that the Universal Cops Headquarter will soon destroy the planet. However, as a citizen of Earth, Rob refuses to leave and convinces Jack to give him an hour to stop the Evil Magic Kingdom/Universal BioBorg Empire team up while seeing that Arlo and Nicole overheard him. As Arlo runs off to get reinforcements, Rob leads a group composing of himself, Nicole, Mindrolly, and Leonard into Phantom World.

At that time, once at the Phantom Castle where her friends are held captive, Yellow Rabbit Ranger finds herself facing Reider and Roborider before Mindrolly teleports her friends out of their cell to help her fight Roborider as Platinor, Kamen Rider Leo and the Morphin Marauders arrive. Fortunately, Kamen Rider Magician arrives in time to dispel the Phantom Space as the Dino Charge Rangers, Universal Cops Rubyor and Sapphiror, and Kamen Riders Cosmo, Astro and Endless King deal with Universal BioBorg Empire reinforcements. As Roborider is defeated by the Dino Charge Rangers, the heroes gather around Reider before he is mortally wounded by a Dragon Breath/Kentro Lance combo.

Refusing to allow it, Platinor sacrificed by using the Drake Spaceship to negate the blast as Rubyor and Sapphiror join in with the Grand Birth and Vavilos. However, the shockwave provides the energy needed as Mindrolly flies off into the core of the Phantom Castle, revealed to be Psycho's actual body. With Reider revived in a new form and an army of Power Rangers monters,Reider reveals Mindrolly as a part of Psycho. The heroes find themselves in a pinch against their enemies until Red Eltarian Ranger and Kamen Rider Warrior Leader arrive with reinforcements that wipe out the Power Rangers monsters, with Kamen Rider Leo defeats Reider with aid from Gold Dino Charge Ranger and a little bit interruption of a now de-powered Exolar for short. As Magician joins the Dino Charge Rangers in fight Psycho within Dino Charge Megazord, Yellow Rabbit Ranger uses the Yellow RabbitZord to reach Mindrolly as it breaks free from Psycho's control and sacrifices itself to protect Nicole.
