Drive Type Technic continuously pumped electricity into Heart, trying to sacrifice himself to destroy the Roidmude before Chase used Execution Spider and separated them. Heart was saved in the nick of time while Drive was seemingly killed from the explosion. Members of the Special Investigation Unit figured out Volt's plan is to create a mass blackout. With the police forces refuse to believe Genpachiro, the team decided to seek out the Volt Roidmude while in his civilian form.
In the Drive Pit, Shinnosuke was revealed to have survived the explosion while being spirited away by three Shift Cars; Deco Traveller, Road Winter and Colorful Commercial (this Shift Car also creates a decoy to cover up their operation). Shinnosuke realised that Volt's blackout plan was based on one of the late author Goro Minami's works and search for clues which lead him to one of the writer's acquaintances, Koya Nishihori, the same criminal that Shinnosuke encountered back in the day before Global Freeze happened. With the help of Jun Honganji, he managed to gain access to Koya's prison cell and get the story's ending. Shinnosuke picked up Kiriko and explained that Volt's plan would be staged on the Electro Mall.
Once they arrived, they witnessed Volt and tried to stop him. However, the Roidmude revealed himself not to be the real Volt, but instead a recreation of the original template. Before Shinnosuke as Drive would face Volt, Brain and Chase interfere, leaving Kiriko to deal with Volt. After setting up his plan, Volt consumed two Spider Viral Cores and morphed into a giant Spider to battle Tridoron. Touched by Drive's plea to step aside for the good of many, Chase releases him but in return having himself attacked by a mad Brain.
As Kiriko is about to be killed by Volt, an unknown figure saved her before Drive Type Technic appeared. Drive used Tridoron to reduce Volt back to his original state and destroy him while Kiriko destroys his device. With the two celebrated their victory, Chase discovers his Roidmude form and number, 000 after receiving damage from Brain's attack. Nonetheless from their defeat, the Roidmudes' main goal was accomplished: to revive one of their comrades, Medic.
When Shinnosuke arrived at a dinner that Kiriko reserved in a restaurant, he realized that his birthday party, Christmas party and the Special Investigation Unit's year end party were all combined into one celebration much to his distraught though he accepted it much later. While Mr. Belt and all of the Shift Cars watched the party from afar, Chase/Roidmude Proto-Zero witnessed his own number designation in disbelief.
- An Asskicking Christmas: Very, very much so. This IS a Kamen Rider series, after all. Drive even finishes of Volt with a Rider Kick!
- Big Damn Heroes: Plenty of those occurred in this episode:
- The trio of Road Winter, Colorful Commercial and Deco Traveller saves wounded Shinnosuke and Mr. Belt.
- When Kiriko is cornered by Volt Ghost's One-Winged Angel form, Mach distracts him long enough for Drive to arrive on scene.
- Continuity Nod: In order to figure out Volt's scheme, Shinnosuke goes to meet the Copycat Pirate, the criminal he apprehended in Episode 0, as the Copycat knew the man whose work Volt tries to turn into reality.
- As an added bonus, he compliments Shinnosuke on solving the Lupin case.
- Christmas Episode: As indicated by the title.
- The Reveal: Chase is a Roidmude, which in itself isn't that surprising, seeing as he works with them. What IS surprising is that he's a human-type Roidmude - number 000, to be precise.
- Saving Christmas: A very interesting take - Rather than saving Santa Claus or restoring the Holiday spirit, Drive has to prevent a major city-wide blackout from occurring on Christmas Eve. It would cause major problems, like endangering people on life support, spread mayhem around the traffic and prevent Christmas trees from lighting up.
- Sinister Silhouettes: Heroic example. A shadowy figure (Kamen Rider Mach) rescues Kiriko from Volt.
- Villainous Rescue: Who is insane enough to try and get in-between Drive and Heart trying to kill the other off, and make sure both combatants are still alive? Why Chase, of course.
- Wham Shot: Drive begs Mashin Chaser to let him go stop Volt, citing that if not thwarted, his plan going to kill hundreds or even thousands of people. Does Mashin Chaser mock the hero for his compassion? No, he actually and seemingly despite himself, stands down.
- This leads to Brain attacking Chase in frustration for letting Drive go, damaging him enough to show his true form: the Human-type Roidmude number 000.
- Xanatos Gambit: So Drive managed to defeat Volt Ghost and prevent a huge crisis from happening? Too bad, the Roidmudes still got enough energy to reawaken the third Roidmude executive, Medic.
- Roidmude Count: 90 plus Roidmude 000 aka Chase.]The Answer: Drive and his comrades.
