Hyper Clock Up
The Hyper Zecter allows access to Hyper Clock Up (ハイパークロックアップ), a version of Clock Up, able to even time travel due to its hypersonic speed properties and the Maximum Rider Power by pushing the horn of the Hyper Zecter again to maximize the power of his finishing attack.

Decade
The Clock Up Attack Ride Card can be used by Kamen Rider Decade when he transforms into Kabuto. As Kabuto, Decade moves extremely fast to the point that seconds slow down into minutes. When this attack is used in Kabuto form, Kabuto Zecter's voice will be played. But Decadriver's voice will be played insteads if Tsukasa stays in his Decade form. In the novel reimagination, Kamen Rider Decade: The World of Tsukasa Kadoya ~The Garden Inside the Lens~, the card somehow ended up in Tendou's possession and give it to Tsukasa after he realized that he is Decade with the card itself being used by Decade while in Kuuga Mighty Form.
 * With the Hyper Clock Up Attack Ride Card, as Kabuto Hyper Form, Decade is able travel at near light speeds, allowing him to travel forward or backward through time. This card is not shown in the TV series, but is used in the S.I.C. Hero Saga side story published in Hobby Japan magazine.

In the World of Kabuto, Tsukasa is given the ability to see in Clock Up space. Daiki's treasure in this world is the Clock Up System.

Counters
With the Faiz Axel Form Ride Card, Decade transforms into Kamen Rider Faiz Axel Form. While in the original series, this form moved at the speed of sound for only 10 seconds, Decade version allows him to match the Worms and the ZECT Riders' Clock Up system which moves at the speed of light. This card is first used in the World of Kabuto to fight Sou Otogiri/Kamen Rider TheBee.

While fighting the trio, Decade became Kabuto and used Attack Ride Clock Up to attack them. He was countered by who used his speed Super Power to match him, forcing Decade out of Kabuto Clock Up.
