Mispider (ミスパイダー Misupaidā, 43 & 44, 13 Riders): A Purseweb spider Mirror Monster. It is able to spew webs from its mouth and use its tusks to drain fluids of its victims. 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 him until the first Kamen Rider Ryuki inferred. Despite receiving aid from Respider, the Mispider was destroyed by the previous Ryuki's Drag Claw Fire. Another appeared, attempting to eat a young girl, but it was killed by the Riders during the fight.
