Aside from this, new riders will be introduced such as a female rider named Kamen Rider Nadeshiko, a high student from the same school, wielding the same Fourze drive. It has been said that our hero will fall in love with our heroine. Her appearance on the TV series has yet to be announced.

Another rider introduced is Poseidon, supposed to be Kamen Rider OOOs nemesis. Poseidon is Nadeshiko's OOO counterpart having a OOO Driver with Same (Shark) on , the dark blue Kujira (Whale), and the dark red Ookamiuo (Wolffish)medals, remnants of the Kougami Foundation.

Next time Kamen Rider Aqua - a rider 40 years in the future. His bike is actually a jet ski - the Aqua Miraider. Its user Michal Minato, Minato came back to OOO time to prevent himself in transforming from Kamen Rider Poseidon. In a time and space anomaly, this future Minato only received his driver in an event that prevented him from knowing the Kougami Foundation. Kamen Rider Aqua is portrayed by Atsushi Arai.

Finally, Kamen Rider W is back with Philip and Shoutaou actors reprising their respective roles. The Kamen Rider Legend 7 will also make their return (Ichigo, Nigo, Stronger, Amazon,  V3, X, Rider Man)
