Steel Dragon, Unmatched

Steel Dragon, Unmatched (鋼・竜・無・双) is the nineteenth episode of Kamen Rider Fourze.

Plot
Arriving at the Rabbit Hatch, having finished the new Horuwankov Foodroid, Kengo finds Ryusei overseeing the testing of the Hand Switch. Feeling left out when Gentaro reveals he made the call on Ryusei to work on the Astroswitches, Kengo becomes upset when the others want to test the new N and S Magnet Switches. Learning that Gentaro took the Magnet Switches behind his back, Kengo declares them to be friends no more and leaves to blow off steam.

Soon after, Kengo meets his old friend, Rumi Egawa of the track and field club as he offers to help her in her work before the track team captain Jin Nomoto tells her to get back to training and warns Kengo not to interfere in her progress. When he hears a thunderous noise, Kengo runs into Gentaro as they encounter the Dragon Zodiarts, who has destroyed several cars to attract the Kamen Rider's attention. Gentaro transforms to fight the Zodiarts, but he is unable to land a hit against the Dragon Zodiarts's hard body as the monster reveals that the Libra Zodiarts has asked him to kill the Kamen Riders.

Overpowered, Ryusei directs Kamen Rider Fourze to assume Fire States and use the Shield Module to take on the defensive. But when Kamen Rider Fourze uses the Magnet Switches, much to Kengo's dismay, he is unable to control their magnetic pull. The Dragon Zodiarts is forced to fall back to escape the magnets, but not before having two trucks get caught in the magnetic pull to kill Kamen Rider Fourze. Luckily, the Powerdizer holds the pair of trucks off long enough for Kengo and Ryusei to turn the Switches off.

Later in the Rabbit Hatch, Ryusei offers a means to modify the Magnet Switches into a phone like device for better use, but Kengo reveals that he already created such an item: the NS Magphone. However, upon finally expressing his feelings that Ryusei is using Gentaro without worrying about the consequences, Kengo is fed up with the others' inability to see the truth and leaves the Rabbit Hatch. While out venting, Kengo realizes Rumi is nearby and helps her improve her running ability before finding himself being attacked by the Dragon Zodiarts under the impression that Kengo is Kamen Rider Meteor.

Upon receiving the completed Magphone as he decides to fix things with him, Gentaro receives a call from Miu about Kengo being attacked. Arriving to Kengo's aid, Kamen Rider Fourze is overpowered by the Dragon Zodiarts until Kamen Rider Meteor shows up. However, even with Kamen Rider Meteor's help, the two Kamen Riders are no match for the Dragon Zodiarts. At Kamen Rider Meteor's urging, Kamen Rider Fourze attempts to use the Magphone against Kengo's wishes, only to accidentally send it flying away. Utterly livid that his advice was not considered, Kengo yells at Kamen Rider Fourze that he is truly an idiot.
