Geiz Myokoin

"I'll take his life."

- Geiz declaring to kill Sougo Tokiwa.

Geiz Myoukouin (明光院 ゲイツ) is a warrior from the year 2068 who transforms into Kamen Rider Geiz (仮面ライダーゲイツ), the secondary rider of Kamen Rider Zi-O.

History
Geiz comes from 50 years in the future where he fought as a resistance fighter against the evil tyranny of the demonic king, Oma Zi-O. He travels back in time to kill Sougo before he can become the king destined to enslave the future.

Personality
Currently not much known about Geiz, except the fact that he is one of the rebellion against Oma Zi-O who lost the fight. He is incredibly stealthy, as shown when he was able to easily sneek up on Sougo using the Time Majin, not being noticed until the last minute by Tsukuyomi. He is also incredibly determined to kill Sougo, as he is the one believed to be Oma Zi-O's true identity in the future.

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

Portrayal
Geiz Myoukouin is portrayed by Gaku Oshida (押田 岳). As Kamen Rider Geiz, his suit actor is Yuya Nawata (縄田 雄哉). Geiz is the first Secondary Rider since Zeronos not to have either Eitoku and/or Jun Watanabe as his suit actor.

Etymology
"Geiz" is a German word which means "stinginess" or "miserliness". However, according to Woz, Geiz actually means "King" (王) in their series as a counterpart to "Zi-O". It is a pun on English word "Gates" since in Japanese and Ancient Egyptian culture, and  both having "gate" etymologies: "a gate connects god and human" or "a gate connects humanity and future". The reason why using "Gates" instead of "Gate" is because of Toei staff's superstition. .
