Darkroaches

The Darkroaches are Category Unknown Undead who are created in overwhelming numbers by the Stone of Sealing once the Giraffa Undead is sealed & Dirk Trent, the Undead known as the 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 Spade Warrior became the Navy Joker, the Darkroaches' existence was no longer needed.
