Dispider (ディスパイダー Disupaidā, 1 & 2): The first of the Mirror Monsters Shinji encountered, a giant gold and white Spider-like monster that targeted women like Ida Megumi. Though destroyed by Knight's Hishou Zan, Dispider was not absorbed by Darkwing and was reformed into a drider version of itself named "Dispider Reborn" (ディスパイダー・リ・ボーン Disupaidā Ri Bōn), now attacking men as well. It was finally destroyed by Ryuki's Dragon Rider Kick and absorbed by Dragredder. In "13 Riders", a purple and brown-colored Dispider was the Mirror Man's final defense, devouring Gai before being destroyed by Knight Survive's Shippu Dan.

Another appeared, attempting to eat a young girl, but it was killed by the Riders during the fight.
