Bat Undead

Bat Undead: The first Undead Diamond Warrior & Spade Warrior encounter in the series, & the third that they hunted down. Able to control bats, the Bat Undead overwhelmed Diamond Warrior in a cave before Spade Warrior arrives to support him.

Once he is blinded by sunlight, the Kamen Riders chased the Bat Undead across the cave to the darkest regions until his wings were clipped by the Diamond Rouzer before being sealed by Diamond Warrior after being hit with a Burning Smash.
