Kamen Rider Zi-O is the final series of Kamen Rider in Heisei Period. The story centers on a young man named Tokiwa Sougo, who poses a threat to the future when he becomes Ohma Zi-O.
To stop this chaos, warriors from the future named Geiz and Tsukuyomi travel back in time to Sougo's main timeline. However, Sougo still chooses his destiny to become Kamen Rider Zi-O and aspires to create a better world in the future.
Kamen Rider Zi-O possesses an interesting power, being able to utilize the powers of all the Riders in the Heisei Period. However, Zi-O doesn't display all of the Riders' armor in the story.

The design of this form is also very interesting, as Zi-O's armor is equipped with miniature statues of the Heisei Riders. In terms of power, GrandZi-O is far stronger than the other Riders. GrandZi-O is able to summon Riders to the battlefield.
In addition, GrandZi-O has a powerful and interesting finishing technique called All Twenty Time Break, which combines the powers of several Riders. However, GrandZi-O's power is still insufficient to defeat Ohma Zi-O.
