Hyper Clock Up (ハイパークロックアップ ) is a keyword introduced in CB09, and is an upgraded version of Clock Up. The keyword's text reads:
- Hyper Clock Up - (When Attacks/Blocks) This Spirit can't be blocked. Also, if the opponent would use a Flash effect, they can't use it unless they pay three extra costs.
As an upgrade version of Clock Up in the show, Kamen Rider Kabuto, Hyper Clock Up enables the user to accelerate to a speed that alters even time. The user can move at a speed that is n times faster than that obtained by Clock Up, and travel to the past or the future as he wants.
While Spirits with Clock Up could still be blocked by opposing Spirits with Clock Up, Hyper Clock Up not only is completely unblockable, but also limits the opponent's Flash responses. Be it Magic, Advent, Change, Accel or a Burst's Flash effect, an additional three core must be paid before it can be used, forcing the opponent to use resources they'd rather spare, or completely locking them out of using Flash. Different from similar effects that target the "use" of cards or effects, Hyper Clock Up adopts the 使う wording, which targets both the "use" and "activate" actions in the game. Hence, even if it is "activating" a Flash effect, the owner would have to pay three extra costs. Additionally, since Hyper Clock Up targets the player, so it isn't stopped by "Your Hand is unaffected" effects.
