Here it is, the appearance of that mysterious Rider that will debut in the finale of Zero-One. As of now, we don't know who is this man and the name of this Kamen Rider. I guess we have to wait to know about this man's name and the name of this Kamen Rider.

In this picture shows that he was using an unknown variant of Hiden Zero-One Driver and the currently unnamed Progrisekey to transform into this Kamen Rider.

It is said that he appeared as a cameo in the finale and he will reappeared in the Kamen Rider Zero-One: The Movie. Maybe the movie takes place after the TV Series before the next Movie War between Saber and Zero-One, just like Kamen Rider Ex-Aid The Movie: True Ending.

What do you guys think?
