Zeztz 2nd Rider description from Vietnam facebook fanpage that previously leak Zeztz forms

>The main theme of Zeztz will revolve around agents fighting in dreams, to hunt down Nightmages - creatures that appear in lucid dreams and the 2nd Rider as well. However, this Rider was trapped in the dream and became a dark hero.

>It is unclear whether this character has a humanoid form or not, but initially this Rider will appear in a silver armor with orange and black lines, looking quite Alien, the head is quite similar to Ryuki but is not considered a Kamen Rider.

>This character also uses the same cross-body Driver system as Zeztz but will be equipped with an additional Unit quite similar to Beyblade in the beginning.

>When becoming a Kamen Rider, this character will use a new Driver, which can rotate 360 degrees with a mechanism to split the Capsule to display images instead of keeping it the same as Zeztz's Driver system.

The mechanism is as follows:
>Put the Capsule on the belt
>Press the lever
>The Capsule will open and display an image similar to the Wonder Ride Book

>This character's Kamen Rider form will split the colors on both sides quite similar to W Extreme:
>One side is silver with a black line
>One side is dark blue with an orange line
>The middle is black with orange eyes

>This character's main weapon throughout is quite similar to Build's Fullbottle Buster, with the main colors of orange and white with two forms Buster and Calibur.
