Kamen Rider Chalice

Ace Form

Wild Form

A Wild Card Rider who is actually the infamous Black Joker Undead, the most powerful of the Undead; the 53rd Existence. He is feared by other Undead as his victory in the Battle Fight would mark the end of all life on Earth.

Unsealed around the time the other Undead were released, Joker battled The Mantis Undead and assumed his form, taking on the name of Chalice. He later seals the Human Undead, who willingly surrendered to him without resistance, using the card to assume human form. The result of using both of these cards to assume their forms for most of the time resulted with both the Human Undead's compassion for life and the Mantis' Undead's fighting spirit collectively suppressing Chalice's natural impulse as the Joker. However, many of the Royal Club Undead who knew his true identity made attempts to dispose of him. On such attempt by the Giraffa Undead ended with an innocent bystander witnessing the battle being mortally wounded by accident in the skirmish. The dying photographer handed him a photograph of his family and Joker decide to protect his family in which he did to atone for his death. The Joker adopted the name Hajime Aikawa, a free lance photographer, after this incident.

Though he thought less of humans originally, Hajime's time with the young girl and the widow of the photographer, Kurihara Haruka and Amane, made him realized that the humans were good beings and wished for himself to be human instead of being the Joker due to his interest of human emotion. Hajime's feelings eventually expanded to Kenzaki, who became a dear friend of his, and then Garren. But when the Caucasus Undead takes most of his cards, the sealed Mantis Undead among them, it causes Hajime to regress back into the Joker after attempting to resist until Leangle unseals Hajime's cards and use the Undead against him. After managing to reseal them all, the Joker goes on a rampage until he is provided with the Evolution Paradoxa, allowing Hajime to have full control of himself. However, this lasted until Giraffa Undead was sealed, with Hajime losing control and his impulse as Joker comes forth with the Stone of Sealing creating his army of DarkRoaches to eliminate all humans. In the end, Kenzaki is the only one to combat him head on.
