Kamen Rider Imperer
Kamen Rider Imperer Rider Statistics Ability Parameters: Being melee-based with Muay Thai-style attacks, Imperer doesn't have much fighting experience, using the Gazelle Visor (ガゼルバイザー) on his right knee to use his Spin Vent card which gives him a double-drill Gazelle Stab gauntlet. Aside from his Spin Vent, Imperer relies on his mass amount of Zelles to do the fighting for him, after which he lands the final blow. His Final Vent Drive Divider (ドライブディバイダー) has the Zelles stampede a target before Imperer unleashes a powerful knee strike to the enemy's head.

Contract Monster
Imperer is the only Rider to have more than one Advent Monster from the start (unlike Kamen Rider Ouja, who had to kill Kamen Rider Gai and Kamen Rider Raia to gain Metalgelas and Evildiver). Besides his contract monster, Gigazelle, he is also joined by Megazelle and Omegazelle because these Gazelle-type Mirror Monsters travel in groups. Although these monsters aided Imperer, he had no cards for the others, save for the primary Gigazelle; this sometimes results in Megazelle and Omegazelle attacking Imperer.

Gigazelle : Resembled a humanoid Gazelle.

Equipment

 * Advent Deck - Advent Card holders, also used as a key to transformation. As long as Imperer holds one, he can detect the presence of other Riders and Mirror Monsters inside the Mirror World, as well as surviving without dying when return to the real world
 * V-Buckle - Transformation belt materialised from a mirror reflection.
 * Advent Cards - Cards that supply the user powers, weapons and Mirror Monsters (if they catch any).

Weapons

 * Gazelle Visor - Gigazelle-like Visor for Imperer to summon the Advent Cards' powers to him and other Riders if he used theirs.
