Spider Undead

The Spider Undead (スパイダーアンデッド) is a recurring villain in Kamen Rider Blade. He is classified in the series as the Category Ace of Clubs Undead.

Overview
The Spider Undead shoots webs from his mouth to entrap his victims, sucking out their lifeforce. He is an accomplice of the Peacock Undead, appearing for Garren to seal while he spewed out golden spiders to latch on ideal hosts. Once finding an ideal host in Mutsuki Kamijou, the Spider Undead intentionally had himself sealed into the Change Spider card to complete the Leangle. Though sealed, the Spider usually takes over Mutsuki's body, using him to become more powerful for the Battle Fight until he no longer needs a human host. Affected by Titan's venom in episode 42, Spider starts to completely take over Mutsuki to the point of turning into the Undead himself. The Spider was forced out from Leangle during episode 42 when attempting to assume his King Form, with Mutsuki free of the Undead's influence thanks to Hikaru Jō giving Noboru Shima a stronger influence. The Spider was properly resealed by Mutsuki with the King Rouser. Though unsealed in Missing Ace by the Albino Joker, the Spider Undead was resealed by J-Garren.
