Worlds that threaten the main universe. Approached by Wateru Kurenai while acquiring the DecaDriver, Tsukasa begins a journey to other Kamen Riders' worlds to save the prime universe as Kamen Rider Decade. But as Decade, besides exhibiting in-depth knowledge of a world he is in, Tsukasa faces both threats that endanger the worlds and the interference of Narutaki who spreads rumors of him as a. But Tsukasa soon understands what Narutaki meant upon learning that he was originally the Great Leader of the Dai-Shocker organization which sought to take all dimensions and that his true mission is to destroy the other A.R. World Riders and their worlds. Tsukasa undertakes the role, sealing the A.R. World Riders in cards before being fatally wounded by Natsumi when she becomes Kamen Rider Kiva-la. His death being the catalyst for the restoration of all the A.R. Worlds and those who died during the Rider War, Tsukasa is revealed by his friends' memories as he, the revived Kamen Riders, and Kamen Rider W defeat newly formed Super Shocker and the revived Neo Organism. Afterwards, Tsukasa and his friends return to the Hikari Studio to continue in their journey across the A.R. Worlds.

Tsukasa utilizes the belt and  to become Kamen Rider Decade, using  to assume the form of a Kamen Rider and access their arsenal via the, , and. He can also use the to transform another Kamen Rider into a new form for a combo attack. During the events of Kamen Rider × Kamen Rider W & Decade: Movie War 2010, Decade becomes a destructive embodiment of himself known as before he was defeated by Natsumi as Kamen Rider Kiva-la.

While in the World of Negatives, Tsukasa acquires the touchscreen cellphone that attaches onto the DecaDriver, replacing the card slot which is moved to his right hip, to enable Decade to assume his true.

During the events of Kamen Rider × Super Sentai: Super Hero Taisen, Narutaki restores Dai-Shocker and enters an alliance with the Super Sentai villains that formed the Dai-Zangyack. Tsukasa, feigning to resume his role as Dai-Shocker's leader, declares war on the Super Sentai and battled Captain Marvelous of the Gokaigers to an epic standstill before faking their deaths to catch the villains off guard once they reveal their actual plan to take over the world. Tsukasa also appears in the Kamen Rider Wizard finale when summoned by the sorcerer Amadum to attack Haruto, only to aid his successor defeat the villain before departing for points unknown.

Tsukasa later returns during the events of Kamen Rider Zi-O to help change Sougo Tokiwa's destiny and ensure he becomes a hero instead of a tyrant using the belt to access the powers and forms of his successor Riders up to Kamen Rider Zi-O. In the special episode Rider Time: Kamen Rider Zi-O vs. Decade: Seven Zi-O!, he gains an upgraded version of the K-Touch that allows him to transform into an upgraded version of his Complete Form called, which allows him to access the powers of all Riders' ultimate forms from Kamen Rider Kuuga's Ultimate Form to Kamen Rider Zero-Two.

Natsumi Hikari
, referred to as by Tsukasa, is a young woman who works at the photo studio under her grandfather, having lived with him since her childhood. . Prior to the series, Natsumi was a member of the  or  for short, a group of dropouts who got bored with school and wanted to find out their own answers. But they never carry out their intent and return to school, promising to meet again years later. At the start, Natsumi begins to have nightmares of Decade prior to finding Decade's belt and giving it to Tsukasa. Fully aware of world's endangerment, Natsumi decides to accompany Tsukasa on his journey to prevent her dream from coming true.

She occasionally keeps Tsukasa in line with the but she had also used the technique on other people such as Yusuke and her grandfather. She also appears to have feelings for Tsukasa, or at least cares for his well-being, which is hinted during her conversation with Yusuke Onodera. Despite Narutaki's offer to save her, she refuses and chooses to see Decade's journey to the end.

However she starts worrying during the time in the World of Hibiki after hearing from Narutaki that Decade's action is actually destroying the world. While in the World of Shinkenger, Natsumi assures Tsukasa that the Photo Studio is his home before her near-death experience by Apollo Geist in the World of RX, learning that Tsukasa used some of his life to save her later. It is only after their adventures in the World of Amazon that Natsumi ponders if there's a point behind their journey.

In Kamen Rider Decade: The Last Story, Natsumi becomes with the use of Kivala, but unlike Kiva, the belt does not materialize first and it does not require Kivala's bite. Instead, it is a kiss to the user's forehead, which then creates a heart-shaped emblem and she becomes the  after transformation. Also different is that Kivala does not perch on her belt during the transformation. As Kamen Rider Kivala, Natsumi is armed with a sword called the with which she uses to perform her finisher, the. Natsumi/Kivala also uses the butt of the Kivala Saber to perform a variation on Natsumi's trademark "Laughing Pressure Point" with a Shocker Combatant as the target. Natsumi transforms into Kamen Rider Kivala to stop Decade Violent Emotion's rampage, being described as the only one able to do so. She later transforms to help Decade, Kuuga, and Diend in order to defeat the rest of Super Shocker, as well as rescue her grandfather from the Super Crisis Fortress. Like Kiva, Kamen Rider Kivala's motif is that of a bat.

Natsumi Hikari is portrayed by.

Eijiro Hikari
is the owner of the Hikari Studio and Natsumi's grandfather. When he discovers that his photo studio is the means of accessing the A.R. Worlds by accident, he is not surprised but amused at the fact and is glad to assist Tsukasa in his mission. Whenever they arrive to a different world, he cooks a different meal each time. Eijiro is also the most easygoing of the group and gets along well with Kivala.

In the World of Decade, Eijiro is revealed to be a guise assumed by Shocker's, an executive member of Dai-Shocker from Switzerland. Doctor Death has the ability to assume the form of the squid-like cyborg, which he claims is his greatest creation. Though seemingly killed in the final battle by Decade, Diend, and Momotaros using several other Riders as weapons, Doctor Death resumes his Eijiro guise, who seemingly forgets ever being Doctor Death to begin with.

In Kamen Rider × Kamen Rider W & Decade: Movie War 2010, the black ShinigamiHakase Memory, given to him by his longtime friend, Ryubee Sonozaki, transforms him into, though his official name is the , the leader of Super Shocker against his will due to the influence of the Gaia Memory. That is also the explanation for Eijiro becoming Doctor Death in the previous movie. He revives the Neonoid to defeat Kamen Rider Decade once and for all. However, Super Doctor Death reverts to Eijiro as the Memory ejects out of him caused by Kamen Rider W Heat Metal's HardMammother Maximum Drive and he is saved by Natsumi in her Kamen Rider Kiva-la form. Afterwards he returns to the studio with the others once Ultimate D is destroyed by Decade and W.

is a young man with a childlike personality at first who has the power to become. Although originally from the World of Kuuga, he eventually joins up with the Hikari Studio group having rid his home world of the Gurongi.

Yusuke Onodera is portrayed by.

Kivala
is a white-colored female Kivat originally from the World of Kiva, where she is Kivat-bat the 3rd's younger sister. She is extremely tiny, small enough to be hidden in an adult's closed fist. She learns of Decade from Narutaki, and uses her power to bring Yusuke into her world, and then sends Tsukasa into another to do battle with Kaixa. She later ends up traveling with the Hikari Studio, though remaining in contact with Narutaki with only Natsumi aware of it. She seems to like Yusuke the most out of the traveling group as she is delighted when he returns to travel with them after they leave the World of Agito. In the World of Hibiki, she assists Ouja in summoning a Bakegani to be used on Decade as Gyuki was not getting the job done, placing her overall goals further into question.

In Kamen Rider × Kamen Rider W & Decade: Movie War 2010, Kiva-la is revealed to be the means for Natsumi to assume her Kamen Rider form: Kamen Rider Kivala.

Kivala is voiced by.

Daiki Kaito
is a mysterious young man who travels through the Kamen Riders' worlds in the hunt for their treasures as, possessing the power to summon Riders to serve him. He seems to know more about Tsukasa than Tsukasa himself does, being an ally one minute and an enemy the next when it suited his thieving needs. He first reveals himself to Tsukasa during his travels to the World of Blade, and reveals that he is Diend while in the World of Faiz, following Tsukasa and the Hikari Studio ever since. Prior to the beginning of the series, Daiki had left his home world (World of Diend) for crimes he committed there, only to return when the Hikari Studio group finds its way there.

Daiki Kaito is portrayed by.

Narutaki
is the central antagonist of the series, a mysterious man who refers to himself as a prophet and is able to freely travel the worlds with immunity to the convergence of the ten worlds. He also has the ability to move freely between the worlds and summon Riders from other worlds. He firmly believes that Decade should not exist in any world, tending to say while tricking the Riders of various worlds to kill him. Arranging a meeting with Natsumi, Narutaki proceeds to tell her that her dreams are tied to the Rider War that will awaken Decade's true nature. After Decade defied his premonitions of doom in the previous nine worlds, Narutaki decides to personally deal with him in the World of Hibiki by summoning a Bakegani, revealing to Natsumi that Tsukasa's actions are actually destroying the worlds rather than saving them as they were told, and that only she can stop the madness now. However at the World of Negatives, Narutaki expresses his joy over Decade finding himself a world which he can exist in. In the World of the Rider War, he asks for Tsukasa's help to stop Apollo Geist from speeding up the destruction of all worlds, but this doesn't change his belief that Tsukasa is the true cause of the destruction, or his desire to see Tsukasa killed.

In Kamen Rider Decade: The Last Story, Narutaki poses as, an executive member of the evil Super Shocker organization. The original Zol is the leader of Shocker's German branch and has the ability to transform into the cyborg, but Narutaki as Zol does not transform in the movie. However, when Doras fell from the Super Crisis Fortress and knocks him out of his way, he reverts to Narutaki and curses Decade for causing a new calamity born from the Neonoid's antics before running off into another dimension.

Narutaki resurfaces again during the events of Kamen Rider × Super Sentai: Super Hero Taisen as, a knight armored general of the newly reformed Dai-Shocker based on the real Doktor G of Destron's Germany branch. Like the original Doktor G, he wields an axe in battle and is able to assume the form of the cyborg. He was defeated by the card-using Kamen Riders using the Goseigers' Tensou Cards before he reverts to Narutaki as he curses Decade again before departing into another dimension.

He appeared once again during the crossover special between Kamen Rider Gaim and Ressha Sentai ToQger. He gave Kota a Rainbow Pass, tells him to give the Conductor and Ticket his regards and leaves, but not before cryptically warning him and Right about an inevitable war between Kamen Riders.

Narutaki is portrayed by.

Dai-Shocker
The mysterious organization is a conglomeration of all villain organizations who set into motion a plan to take over all dimensions due to someone providing the means to do so. Based on the World of Decade, their insignia is double-headed version of Shocker's eagle crest, but with the "DCD" written on it that hints at Decade's ties to them. In addition to Doctor Shinigami and Doktor G, there are many other members of Dai-Shocker that come from previous Kamen Rider Series. They sent their agents out across the worlds for universal domination. During the events of Kamen Rider × Super Sentai: Super Hero Taisen, Tsukasa Kadoya reforms Dai-Shocker and becomes their Great Leader once more in order to take down the Super Sentai teams and the Dai-Zangyack group led by Captain Marvelous. However, it is revealed that it was a plot between Dai-Shocker and Dai-Zangyack all along to have the Super Sentai and the Kamen Riders wipe out each other. Both groups of villains are defeated after Tsukasa and Marvelous reveal to them that they knew about their scheme all the time, having the heroes they supposedly "destroyed" sent to an alternate dimension and summoned back all together for the final battle with them.

Apollo Geist
The first member of Dai-Shocker Tsukasa confronts, is the Security Chief of Dai-Shocker, hastening the worlds' convergence to make invasion easy for his organization. He normally assumes the form of a man called until he invokes. Originally from the, he was revived by the Government Of Darkness after being killed by X-Rider. However, his lifespan is short as a result and thus uses the Perfecter to take the life force out of people to augment his own. When the Perfecter is stolen from him by Diend   and then destroyed by Decade,    Apollo Geist eventually comes up with the plan to marry Yuki, the Fangire Queen, becoming a Fangire as a result. As a result of his transformation, he now becomes with the ability to remove other realities from existence. Using his power to revive the monsters from the Nine Worlds and attempting to make Natsumi his bride after Yuki is destroyed by Decade Complete Form, Super Apollo Geist fights Decade and Diend until help arrives in the form of Hibiki and Kiva. Kiva and Hibiki distract Super Apollo Geist long enough for him to be mortally wounded by Decade Complete Form with Diend's power, Geist swearing that he will "revive as the greatest nuisance in the universe" before he is destroyed. Later revived during the events of Super Hero Taisen, Apollo Geist is destroyed again by Kamen Rider Fourze in Magnet States.

He has the GaGa Armlet and seeks Amazon's GiGi Armlet to gain their full power and use the unlimited ancient Inca powers to complete his master plan of converting humans into monsters. He normally resembles a torso attached to a large boulder, but he can also assume a humanoid form adorned with the faces of the ten Heisei Kamen Riders from which he can access their powers and counter any of the ten Heisei Kamen Riders attacks.

It is noteworthy that Kenzaki is able to transform directly to King Form using just the Change Beetle card alone as the belt now uses Kamen Rider Leangle's "Open Up!" feature, rather than the original "Turn Up!" feature, projecting a gold-colored version of the transformation screen that depicts the Evolution Caucasus beetle.

Alternate Kamen Rider Decade
In the director's cut of the film, Natsumi has a dream where she sees Tsukasa being attacked by an evil doppelgänger of himself which transforms into a version of Kamen Rider Decade Complete Form which has a series of Decade Complete Final Kamen Rider Cards instead of the Kamen Ride Cards of the Nine Worlds' Kamen Riders. This other Kamen Rider Decade attacks the original Tsukasa, shortly before Natsumi wakes from her dream. The scene featuring this encounter originally appeared in the teaser for the film in the television series' finale.
