Chameleon Undead

The Chameleon Undead (voiced by Katsumi Shiono) is an Undead whose capable of changing itself into the appearance of anyone he sees, complete with their abilities.

Hiroshi Tennoji had this Undead in its sealed form and fused it with the Poison Scorpion Rouze Card to create Titan Undead. However, it was split again and resealed.

A year after Kenzaki's sacrifice into a Joker-class undead, he was unsealed again by Tachibana and Chief Karasuma under the intention to transfer a bit of his ability to the Jokers in order to turn them into normal humans but it escapes and steals the BOARD data and transforms into the imitation of Kamen Rider Blade and chased after Hajime due to his nature of being a Battle Fight competitor. While everyone is throwing a graduation party for Mutsuki and Nozomi, Blade burst in from the front door and attacks Hajime. Everyone is confused but then Garren shows up in the window and starts firing Blade.

After explaining everything, he hands over Hajime and Mutsuki’s cards and the Leangle Buckle as they fight the fake Blade, but it transforms into Jack Form. Mutsuki remains useless as none of his powers grants him the ability to fly.

Tachibana warns Hajime as the Chameleon Undead has all of the BOARD data making it easy for him to fight. The Chameleon Undead transforms into King Form and finishes off the Riders.

With all of hope seems lost, Hajime even forced himself to evolve into Joker Undead but the fake Rider itself outsmarts him leaving a heavy wound on his chest.

As the Rider about to finish Leangle, Joker steps in and takes the blow. At first he thinks that it was Hajime/Chalice but it has no slash mark and he was lying after sustaining the damage on its chest.

Realizing the second Joker's true identity, Tachibana quickly tosses the Joker the Blay Buckle, Rouze Absorber and a collection of Suit of Spade Rouze Cards. Thus, the Chameleon Undead was defeated for good.
