Takumi Kobayashi

Takumi Kobayashi (小林匠) is a 17 year-old who transforms into Kamen Rider Geiz (仮面ライダーゲイツ), the secondary rider of Kamen Rider Zi-O.

History
Takumi was born the same day when Kamen Rider Ryuki's second episode released. He befriended Ruby Rose and Sora Nakamura, and later wanted to kill Sora because of him thinking Ryutaro Soma is innocent.

Powers And Abilities

 * Genius-Level Intellect: At the very least, his use of BuildArmor and his finisher, Vortex Time Burst, indicate that Geiz is proficient in equation and scientific formulae.

Forms
Like Zi-O, Takumi transforms by inserting the Geiz Ridewatch into the right-hand side of the Ziku-Driver and rotating the Driver 360 degrees. He accesses Rider Armor (ライダーアーマー) forms based on previous Kamen Riders by inserting Ridewatches into the left-hand side of the Ziku-Driver.
