In , Arata Kagami seeks to get the Hyper Zecter just like Souji Tendou, so he tries to emulate Tendou. Once he realizes that he has to be himself, the Hyper Zecter appears and allows him to transform into Kamen Rider Gatack Hyper Form, which only appears in the DVD. The Kabuto and Gatack Zecters speak to Tendou and Kagami throughout the DVD, voiced by Tomokazu Seki and Kōji Yusa, respectively.
