An Atypical tarantula monster. It appeared among the Mirror Monsters that helped to protect Yui. A Mispider appeared in the 13 Riders special where it dragged Shinji into the Mirror World to eat until the first Kamen Rider Ryuki inferred. Despite receiving aid from Respider, Mispider was destroyed by the previous Ryuki's Drag Claw Fire. Another appeared, attempting to eat a young girl, killed by the Riders during the fight.
