Darkroaches

The Darkroaches appeared in 2004 TV series called Kamen Rider Blade. The Darkroaches (ダークローチ Dākurōchi) are Category Unknown Undead who are created in overwhelming numbers by the Stone of Sealing once the Giraffa Undead is sealed and Hajime Aikawa, the Undead known as Joker, is the victor of the Battle Fight. They serve Joker for purpose of destroying all life on the Earth prior to the Battle Fight resetting, targeting humans endlessly. When they die, they dissolve into green mist, only to be replaced with even more Darkroaches thanks to the Stone. Once Blade became the second Joker, the Darkroaches' existence was no longer needed.

In the World of DiEnd, the Darkroaches are the minions of Fourteen and serve under Bossroach, going after any one who breaks the law. Many of them are killed by the Riders and when their master is destroyed by Decade Complete Form and Armed Hibiki, the remaining Darkroaches fade away into nothingness.

Other versions of the Darkroaches appear among the rankings of Dai-Shocker.
