This article is about a/an ability in Kamen Rider Kabuto.
The Clock Up (クロックアップ Kurokku Appu) ability enables ZECT Kamen Riders Masked Rider System to travel at speed of light to match the speeds of the Worms, who are also moving at super speed. According to the narrator of Kamen Rider Kabuto and the characters in the show, Clock Up was supposedly light speed. However this was disproven when Kabuto aided Arata Kagami where a bullet from a handgun was still travelling at a relatively fast speed, making Clock Up's supposed light speeds either be exaggerated, or variable.
  • This is more evident when Kamen Rider Kabuto and Kamen Rider Gatack faced against Kamen Rider Caucasus, who donned the Hyper Clock Up and moved way faster than the two of them while they were in Clock Up.
  • Another case to Clock Up's actual speed is when Kabuto and Dark Kabuto face off in their final confrontation on top of falling platforms that appear to be falling instead of being nearly frozen in place if it were at light speeds.
  • In every crossover where a Rider that possesses super speed that isn't associated with Clock Up and is pitted against the ZECT Riders, they're able to fight evenly with them.

Clock Up users

Hyper Clock Up

The Hyper Zecter allows access to Hyper Clock Up (ハイパークロックアップ Haipā Kurokku Appu), an upgraded version of Clock Up, allowing them to move at speeds that are estimated to be twice as fast as a regular Clock Up. It also has the ability to time travel due to its faster than light speed, allowing its user to rewrite history. It also has a "Maximum Rider Power" mode that increases the output of a Rider's finishing attack.

However, Hyper Clock Up was shown to unmatched with the Freeze ability of Cassis Worm, nor showing the ability to stop time.

Riders who have used Hyper Clock Up


Attack Ride Clock Up

Kabuto Clock Up

Decade is also able to perceive the battle of superspeed fights and can also utilize the Clock Up Attack Ride Card if he transforms into Kamen Rider Kabuto via a Kamen Ride card. While as Decade Violent Emotion, Decade can use Clock Up without the need of transforming into Kabuto first.


While Clock Up's ability is to move at super speed, there are those who can counterattack or have a defense against it. Within the crossovers of the Kamen Rider multiverse, there are those with the ability to counter or match the speed of Clock Up.

  • Starting off with Kamen Rider Faiz, in a showdown in Kamen Rider Decade, Decade transforms into Faiz Axel and utilizes the form's super speed to combat the ZECT Riders' Clock Up. Though Faiz Axel has been noted to move at the speed of sound while Clock Up has been noted to move at the speed of light, this means Faiz Axel may be capable of moving at light speed for short times.Warning: Kabuto Running Amok
  • Kuuga Pegasus form's heightened senses can allow him to track and target foes moving at Clock Up speeds, as shown with Decade's use of the corresponding Form Ride Card.
    • Kuuga Ultimate form (and its upgrades) would therefore be an even bigger threat to Clock Up users, due to having both Pegasus form's heightened senses and the limited ability to transmute matter itself.
  • Kamen Rider Decade can copy the abilities of other primary Riders from the Showa to Heisei eras, meaning he can utilize most of the written counters on this list.
  • All Kamen Riders and Kaijin who can travel through time could in theory, use their powers to wipe out Kabuto Riders before they use Clock Up. If the opponent is somehow immune to the effects of time alteration (such as a Singularity Point) though, this counter would prove useless.
  • In Kamen Rider Decade, there exists a Clock Down (クロックダウン Kurokku Daun) generator, created by Sou Otogiri. Once activated it can disable users from using Clock Up, thus reverting them into normal human speed.
  • Kamen Rider Stronger has been shown to temporarily halt the Clock Up function by using an Electro Fire attack to create a radial blast of electricity, causing Kabuto to forcefully exit Clock Up due to his Rider form's equipment getting zapped by the attack's energy. Contextually, this only worked because Kabuto walked right into the attack. Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai
  • In Super Hero Taisen GP: Kamen Rider 3, as Axel Form was shown to be rivaled by both Clock Up and Kamen Rider Mach's super speed, it is safe to presume that Mach's speed can rival the Clock Up as well.


  • Kamen Rider Blade and OOO have the ability to stop time, similar to the Cassis Worm Dimidius. This would mean they can not only counter normal Clock Ups, but even Hyper Clock Ups.
  • The ability of Heavy Acceleration distorts space and gravity, making anyone in its radius feel heavier and more sluggish, which would either hinder, negate or allow someone unhindered by the effect to rival those moving with Clock Up, though it could be negated by Hyper Clock Up as it is unaffected by such distortions (it can reverse or advance time while making the Rider move at almost twice the speed of light).
  • Much Like Kamen Rider Blade and OOO, Kamen Rider Cronus is able to freeze time, so he could theoretically stop a Clock Up Rider in their tracks as well.
    • However the Hyper Muteki Gashat used by the Ex-Aid riders provides them protection from Cronus' ability, thus allowing them to move within the temporal halts. This theoretically could allow the Riders to move at the speed of light, but only when someone halts time, and not actually an ability of their own.
  • A trailer for Kamen Rider: Climax Fighters shows Ex-Aid, under the influence of the Speeding-Up Energy Item, being able to match up with Faiz Axel Form's super speed. In theory, said Energy Item's effects could possibly match up with Clock Up as well.

Behind the scenes

In popular culture

  • Episode 327-B the comedy anime Sgt. Frog (ケロロ軍曹 Keroro Gunsō) titled "Keroro, Invasion in a Blink!" features the members of the Keroro Platoon trying to invade Earth in Clock Up mode.
  • In Haiyore! Nyaruko-san, Clock Up is officially listed as one of Nyarko's unique powers, though she has yet to demonstrate it. However, it's referenced in the first episode when Mahiro asks how Nyarko had time to make him a box lunch that morning and she replies "A Clocked-Up Nyarlathotepian can move at speeds that defy all logic!" (Both the Crunchyroll and NISA versions mistranslates Clock Up as "overclocked", but this could be the result of a licensing issue.)  The ability is referenced again in the Nyaruko-san game for PlayStation Portable.
