All spoilers for Kamen Rider OOO are unmarked. You Have Been Warned!
Happy Birthday, OOO!
Kamen Rider OOO 10th: Core Medal of Resurrection is a Kamen Rider OOO V-Cinext film celebrating the 10th anniversary of the series. It was released on March 12, 2022.The year is 2021, ten years after Eiji first became Kamen Rider OOO. The ancient OOO has come back to life and brought with him the Greeed, Uva, Kazari, Mezool and Gamel to exterminate humanity and take over the world.
Eiji's friends all form a resistance to fight the ancient OOO, but Eiji himself disappears after clashing with the ancient OOO. Ankh is then mysteriously revived and joins up with the resistance to figure out what happened to Eiji and stop the ancient OOO. What will be the fate of Eiji and Ankh? Now, the battle of the kings for the survival of mankind begins...!
Provides examples of:
- Advertised Extra: Eiji was touted as being the main character alongside Ankh in the trailers and promotional material, but his role in the film is comparatively minimal, with Goda possessing his body for most of it, and the real Eiji only appearing in a brief flashback at the beginning and for a few minutes at the end before passing away.
- Back from the Dead: Prior to the start of the film, the Ancient King OOO revived from his 800 years long slumber, and he brought with him the four Greeed.
- Big Bad: The Ancient King OOO, previously the Greater-Scope Villain of OOO, who has now revived in modern times and set forth to put his plans into motion to conquer the world.
- Bittersweet Ending: Even a single event can make a bittersweet ending way more bitter. Ankh wakes up to find himself in a war-torn world torn apart by the revived king OOO, and, to top it all off, Eiji is dead, with Ankh's revival having happened as a result of Eiji's dying wish. But Eiji is perfectly satisfied and at complete peace, because he'd finally been able to clear his regrets and use his death to achieve his greatest wishes in saving a young girl in the same way he couldn't in the past and allowing Ankh to live. Ultimately, after years of Walking the Earth trying to make up for his past failure and searching for a way to restore Ankh, the two are finally able to briefly meet again, Ankh fulfills his request to fight together and protect everyone one last time, and Eiji dies knowing exactly what he wanted, having accomplished it the way he wanted, and surrounded by his friends.
-
Broken Aesop: The ending's implied aesop of Ankh needing to let go of Eiji and get over his death rather than cling to him is undercut by the fact that Eiji himself has spent 10 years trying to revive Ankh. - Can't Kill You, Still Need You: Heroic example overlapping with Teeth-Clenched Teamwork. The Resistance only works with Goda to preserve Eiji's body.
- Central Theme: The consequences of what happens when The Hero Dies.
- Curb-Stomp Battle: Every battle in the film.
- Eiji is completely outclassed against the Ancient King, who fatally wounds him.
- The King and the Greeed have been delivering these nonstop to the human resistance forces until Ankh arrives.
- Uva is subject to one at the hands of Goda as OOO, who has to be stopped from destroying his Core Medal. Not that it spares him from the King's wrath.
- The Births are smacked around in both of their major engagements, first by the King then by Goda.
- Goda is demolished by TaJaDol Eternity.
- Darker and Edgier: Compared to the lighthearted tone of the main series, this V-Cinext film is much darker. Notably, it begins with the Ancient King OOO and the Greeeds landing waste to the world, and the moment where Eiji is revealed to be dead before the beginning of the film and is only being brought back alive by Goda marks the point where the tone becomes more depressing compared to the previous V-Cinext Kamen Rider Saber: Trio of Deep Sin.
- Dark Reprise: A more somber version of Anything Goes! plays throughout the first part of the credits after Eiji dies for real.
- Deconstruction: The 10th anniversary movie deconstructs Sacrificial Revival Spell. Eiji was successful in reviving Ankh, but he had to die in order to do so. While the first half of the movie focused on defeating Ancient OOOs, the other half shows what the consequences Eiji's death had to the main cast and how they needed to cope with it. And because desires won't vanish even if someone dies, the Kougami Foundation decided to create an artificial Greeed that fittingly becomes the Final Boss.
- Decoy Protagonist: The advertising and even the main poster are made to make you believe it's about Eiji and Ankh being Bash Brothers as usual, but the actual movie more closely follows Ankh's perspective as he's a Fish out of Temporal Water after his sudden resurrection and trying to piece together what's going on, with Eiji cryptically appearing and not being straightforward about his intentions. It eventually turns out "Eiji" isn't even actually Eiji, but Goda in his body, and the real one only shows up in the climax to help Ankh. Further cementing his role as the main focal character of the movie, Ankh (in Eiji's body) is treated as the main one transforming into TaJaDol Combo Eternity.
- Demoted to Extra:
- Even though Eiji is Kamen Rider OOO, it's Ankh who's the main character. Eiji himself gets comparatively little to do in this film, as most of his interactions with people are really Goda possessing him and speaking through him. However, much of the movie does thematically revolve around him, with the story's central drama involving everyone trying to figure out the best way to carry out his wishes.
- The Greeed were the Big Bad Ensemble of OOO, but here they're minions of the King. The only one who gets a proper fight with OOO is Uva, while the rest spend most of the film sitting around before being absorbed by the King.
- Deuteragonist: The film is just as much about the unscrupulous new Greeed that's taken over Eiji's body as it is about Ankh's efforts to investigate the revival of the Ancient King.
- Diabolus ex Machina: Eiji is and has been dead for a while. Now an artificial Greed is possessing him.
- Downer Beginning: At the start of the film, the Ancient King OOO has come Back from the Dead and laid waste to the world.
- Drunk with Power: Kamen Rider Goda is, effectively this; only formed when Goda chooses to act on a whim and absorbs the Core Medals left behind by the Ancient OOO.
- Foil: Goda to Eiji. Eiji eventually discovered his desire was to gain power to protect what he cared about. Goda eventually reaches the same conclusion for power's own sake.
- Also to Ankh, both being Greeed directly connected to the desires and motivations of Eiji Hino. Ankh has undergone enough Character Development to subtly care about the man's desires; going so far as to fuse with his body to defeat the Final Boss. Goda pretends to care about the man's desires but has no personality beyond taking Eiji over and sheds him like baggage at the first opportunity to become said Final Boss.
- Hourglass Plot: Eiji spent a good part of the last 10 years seeking a way to bring Ankh back to life, here he succeeds... Technically, as he was long dead by the start of the film and after Ankh resurrects for good, Eiji himself dies to Ankh's distress, essentially swapping the roles the two had over the last years.
- Inciting Incident: Eiji's death at the hands of the Ancient King allows Goda's creation and eventually Ankh's revival.
- Motive Decay: Played for Drama. Goda initially makes himself seem unscrupulous yet at least beneficial; wanting to "become Eiji" to satisfy the man's desires. When push comes to shove however, he chooses power over Eiji; having learned nothing.
- Mythology Gag: TaJaDol Eternity shares visual cues with an SIC figure depicting the final battle from the main series; TaJaDol Lost Blaze, a version of the combo using Ankh's true Core medal.
- Nice Job Breaking It, Hero: Goda owes his existence to the Kougami Foundation deciding making their own artificial Core Medals was a good idea.
- Nominal Hero: Goda helps the Resistance by virtue of opposing the King. He has no intention of sacrificing himself and in fact dumps Eiji the moment he has a shot at gaining power.
- Oh, Crap!: Uva's reaction to Goda nearly destroying him wholesale as OOO.
- Out-of-Character Alert: Ankh and the resistance first notice something is up with Goda/Eiji when he nonchalantly shrugs off a little girl's death, something the real Eiji wouldn't get over so easily.
- Plot-Irrelevant Villain: After spending most of the movie as a plot device to keep Ankh from being able to properly interact with Eiji, Goda ends up as this when he becomes the Final Boss. By that point the main plot around the Ancient King OOO had already been resolved, and Goda's only purpose there was to give Eiji and Ankh a foe to fight together against.
- Plot-Triggering Death: It's eventually revealed Eiji's death was what kickstarted the events of the plot when he used what little was left of his life force to revive Ankh. The rest of the story involves Ankh trying to piece together what happened as a result, and the conflict between him and Goda regarding how to fulfill his wishes in the aftermath.
- Post-Climax Confrontation: Ankh and OOO defeat the King and stop his rampage. However, Goda then absorbs his Core Medals and becomes Drunk with Power, giving us one last foe Ankh and Eiji need to work together to defeat.
- Replacement Flat Character: Goda, twofold.
- Goda is effectively a pre-Character Development Ankh, but with none of the substance. Possessing Eiji is the only thing that defines him and his only choice throughout the film is to force himself into becoming the Final Boss.
- Kamen Rider Goda is a kitbash of the Ancient King OOO's final form with a new head. It has none of the King's finesse and only punches things. Barring intermittent cutaways, it's destroyed in less than three minutes of real time.
- Satellite Character: Goda's entire existence is dedicated to being connected to Eiji. Becoming the Final Boss is the only thing he ever does on his own and even that is tangentially connected to Eiji's desire. Justified however, as he was literally born from it.
- Spoiler Cover: The poster for the movie has Goda's One-Winged Angel form rather noticeably placed near the upper left corner.
- Teeth-Clenched Teamwork: Ankh and the resistance aren't particularly trustful of Goda, but work with him anyway because he's the only one keeping Eiji's body alive and they need to focus on stopping the Ancient King OOO.
- The Resistance: The aptly-named "OOO Resistance" are the only people fighting back against the King and the Greeed. They're steadily losing by the time Ankh finds them.
- The Worf Effect: Birth X's debut sees both it and the original pummeled by Goda.
- What Happened to the Mouse?: There is never a proper explanation given for just how or why the Ancient OOO returned, where the second OOO Driver came from, or how the other four Greeed were revived.
- You Have Outlived Your Usefulness: The King absorbs the Greeed into himself after Uva's near-death at the hands of Goda.
- Goda frees himself from Eiji's body to absorb the King's Core Medals.
