This article is about a/an group of monstrous Kamen Riders in Kamen Rider Zi-O.

Another Riders (アナザーライダー Anazā Raidā) are a group of monstrous Kamen Riders that are based on the past Kamen Riders, affiliated with the Time Jackers, provided they originate from the World of Kamen Rider[1]


Another Riders are created when people from the past (or future) make a contract with the Time Jackers in order to receive the power of the current Kamen Rider from their timeline. Once a contract is made, a Blank Watch becomes an Another Watch, which the Time Jacker inserts to the host's body. However, rather than becoming the actual Rider, they instead take on a monstrous aberrations that match the Rider in appearance, with powers only varying in dissimilarity. Once an Another Rider is created, the certain Legend Rider loses all of his powers, his memories of becoming a Kamen Rider, as well as his enemies being erased from existence, drastically changing the history during their respective timelines. The new users have some form of control over their Another Riders' powers, and can transform into their monstrous forms at will.

Another Riders can only be destroyed by by Kamen Rider using the Armor or Futurering Form of whom the Another Rider were based off of, or by using DecadeArmor, provided Zi-O is augmenting it with the appropriate Ridewatch. Defeating them through other means will only incapacitate the Another Rider momentarily, with the Time Jacker needing to reset the Another Watch and putting it back to the host's body. Afterwards the user continues to become that Rider and they are able to respawn countless times each time they are put down.

In between the period where the Another Rider is temporarily defeated, the original Riders' powers and memories also return temporarily, allowing them to interact with Sougo and Geiz properly and give them their respective Ridewatches. After which, Zi-O and/or Geiz travel back in time when the Another Rider was created and defeat them permanently through the power of the Rider Armors solely or by DecadeArmor augmentation. The side-effect of this, however, is that once the Another Rider is destroyed, the changes made during the altered timeline also become permanent. This rule does not apply to Another Riders in a timeline before the actual Rider's creation as they do not exist. Therefore, they can only be defeated through Kamen Rider Woz, who has the ability to create the Miridewatch required to permanently defeat them.

However, the creation of Another Riders cannot erase Kamen Riders with certain unique traits, as some Riders have shown at least some resistance to the effects of their Another Rider counterpart's creation. Ryotaro Nogami and the Taros are Singularity Points, meaning temporal changes in the past cannot and will not affect them. Due to Kouta Kazuraba's status as a god, the creation of Another Gaim preserves his being, but only temporarily. The timeline alteration and God Kouta's erasure from existence becomes imminent once Another Gaim is defeated.

While uncertain, there is a high possibility that a Another Decade cannot be created as the Time Jackers do not have knowledge on Tsukasa Kadoya's origin of being, which supports the fact that Decade is not from our prime dimension. This claim is further supported following the fact that Woz seems to be the only one who is aware of his existence.


The first known Another Rider, Another Build, was created in 2017, transforming from a basketball player, originally destined to die, after he was saved by Heure , who provided him with the Another Build Ridewatch. Kingdom 2068

The second Another Rider, Another Ex-Aid was created in 2016. He was a father who's son was hospitalized for an unknown reason. Offering to save his son, Ora provided him with the Another Ex-Aid Ridewatch.Doctor Gamer 2018

The third Another Rider, Another Faiz was created in 2003. Sakuma, a student who felt guilty about his girlfriend's death, was offered the Another Faiz Ridewatch by Ora, and used in order to save her. This power, however, eventually waned as it started to weaken in 2011. Made desperate by the fact his power was fading away, he was approached by another Time Jacker, Sworz, and was given the Another Fourze Ridewatch, becoming the fourth Another Rider, Another Fourze.Switch On! 2011 555・913・2003

The fifth Another Rider, Another Wizard was created in 2012 when Hayase, a stage hand on a rundown magic theatre is found by Heure. To save the theatre, Hayase formed contract with the Time Jacker and achieve magical power. At first, Hayase only uses his newfound magic power to perform magic shows that returns the theatre to its former glory, but after knowing that the theatre is going to be closed down anyways, he went berserk and attacks his show companions. 

Powers and Abilities

  • Invulnerability: Another Riders are essentially invincible to anything other than their corresponding Kamen Rider or Rider Armor and will re-spawn indefinitely if defeated outside those conditions.Best Match 2017


  • Corresponding Rider power: An Another Rider can be harmed and killed by the Kamen Rider they are derived from. Though their presence would soon cause that Kamen Rider to be erased from history, their power can be preserved and replicated through the Ridewatch wielded by either Zi-O or Geiz in the form of a Rider Armor. Once a Another Rider is defeated by the corresponding Rider Armor, they are permanently neutralized as their Another Ridewatch is destroyed. Best Match 2017 It is unknown if other methods of replicating a Legend Rider's power, like with Decade's Rider Cards, has the same effect.
    This weakness can be fixed by having multiple Another Rider' powers in oneself. As long as the first power is not neutralized, that Another Rider would continue to resurrect even when destroyed by the corresponding Rider Armor.Switch On! 2011
  • Power Decline: Another Riders' lifespan are rather short, lasting about 7 years. 555・913・2003 The only way to prolong their lifespan is to take a new Another Riderwatch, gaining a new Another Rider form from it if said Ridewatch is different. Oddly enough, Another OOO managed to subvert this by maintaining his transformation for 8 years.

List of Another Riders


Kamen Rider Heisei Generations FOREVER


  • The Another Riders are designed by Yutaka Izubuchi (Another Build[2], Another Ex-Aid, Another OOO[3], Another Ghost[4], Another Shinobi) & Tamotsu Shinohara (Another Fourze, Another Faiz[5], Another Wizard[6], Another Gaim[7]).
  • Theme wise the Another Riders are slightly similar to the Negative SyndicatesIcon-crosswiki of the 30th Super Sentai GoGo Sentai BoukengerIcon-crosswiki as both are themed after something from their predecessor seasons.
    • Another Riders are themed on past Kamen Riders. So far, only primary Riders have been shown to have been copied. They're also connected to them directly, becoming monsters by receiving the power to become a Kamen Rider. However there is no Another Decade, as erasing Decade from the timeline means erasing every last Kamen Rider’s timelines from reality.
    • The villains and monsters in the Negative Syndicates are themed after past Sentai MechaIcon-crosswiki and Robo'sIcon-crosswiki. (EX. ZukangamiIcon-crosswiki of the Dark ShadowIcon-crosswiki is based on Denji Gattai Galaxy MegaIcon-crosswiki from the 21st Super Sentai Denji Sentai MegarangerIcon-crosswiki.) However, their connections to the past Mecha are purely visual and sometimes thematic homages, without actual acknowledgement that they're mimicking them in the story itself.
  • Another Agito, a Kamen Rider that already exists in Kamen Rider Agito seems share a name conflict with the Another Riders. However, according to producer Shinichiro Shirakura in recent interview, they haven't thought what to do with Agito's Another Rider counterpart which will appear later in Kamen Rider ZI-O.[8]
  • The Another Riders use concepts from past Rider season Monsters.
    • The Another Riders being humans using twisted versions of a Rider Collectible to transform is similar to the Dopants from Kamen Rider W and the Zodiarts from Kamen Rider Fourze.
      • The concept leans more towards Dopants as the device is used in both monster creation and Form changes.
      • Both monster types are normally defeated by a finisher using the power source of the same system, Maximum Drive and Limit Break, respectively.
    • The concept of being created from making a contract with a Time Jacker is similar to the Imagin from Kamen Rider Den-O.
    • The concept of humans turning into out of control monsters is similar to the Category H Inves from Kamen Rider Gaim.
      • Concept-wise, they are less belligerent and more single-minded in intent. As each Another Rider is given free rein over their actions, but under the intent to cause destruction, their actions are similar to the Fusion Roidmudes from Kamen Rider Drive.
    • The idea that the system the devices stem from can create both Riders and monsters is similar to the Gamma from Kamen Rider Ghost and the Bugsters from Kamen Rider Ex-Aid.
      • The more grotesque appearance of the Ridewatches is similar to how Gamma Eyecons were more eyeball-like in design.
  • Another Riders have the name of the Rider they're based on & the air year of the Rider on different parts of their bodies.
  • The characteristics of the people who become Another Riders appear to be the opposite of their original Rider counterparts.
  • Kuroto Dan (Kamen Rider Genm) is the first veteran Rider (so far) to become an Another Rider (Another OOO).
  • Another Riders' forms seem to draw aspects from their bases' more powerful forms:
    • Another Build: A mix of RabbitTank Hazard's and RabbitTank Sparkling's design aesthetics.
    • Another Ex-Aid: Hyper Muteki's "hair".
    • Another Ghost: Toucon Damashii's Persona design
    • Another Gaim: Kachidoki Arms' armor design and weapon type.
    • Another Wizard: The coat design of Flame Dragon.
    • Another Fourze: Cosmic States' Module Access.
    • Another OOO: Super Tatoba Combo's coloring.
    • Another Double: The bird-like design of the belt from CycloneJokerXtreme's Xtreme Memory, and the Joker half's spikes from FangJoker.
    • Another Den-O: A mix of the train track designs from Den-O Climax Form and New Den-O's Strike Form.
    • Another Faiz: The Rider Kick-like attack of Blaster form's variant of the Crimson Smash.
    • Another Kuuga: A potential force of destruction like Kuuga's Ultimate Form.
  • Another Riders appear similar to or display abilities/quirks from their monster contemporaries:
    • Another Build - Consumption of Smash Bottles and him going berserk are based on early victims of Smash experimentations.
    • Another Ex-Aid - A living plague of Bugster Viruses.
