- Manta Flyer - is a creature similar to a stingray only with tusks and feet. They fly to their opponents and grab them with their feet. They also have a roar similar like a wolf.
- Bugs - Bugs are small creatures that are 8 feet (two pincers seem) and are wavy, have the appearance of a scorpion just do not have a head. It may be equivalent to termites. His roar is much like a cat.
- Decay Soldier - is a monster with oval face, his mouth has 8 tentacles as if resembling jellyfish and has the appearance of an android. It is a bit strong but with some attacks the monster is knocked out. You can also absorb bugs to get bigger as in episode 25. His roar is similar to a tiger (in particular its roar changes).
- Decay Fighter - It is a giant headless monster, his hands are large with which can crush your enemy has a medium body enough and can grab his opponent. With several cuts is defeated, but in a trice is reformed. It is the only monster that does not roar.
Towards the end of Season 1, the Trix seemingly stole the Dragon's Flame from Bloom and used it to summon the army and destroy Red Fountain. When the Trix were defeated, the entire army vanished before everyone's eyes because Icy, Darcy and Stormy no longer had the strength to command it, and because the power of the army depended on that of the Trix.
One important characteristic is that for each monster cut or killed, two more will appear. The monsters can also unite into one beast. Only a possessor of the Dragon's Flame (or something with equal power) can summon it with its spell, though Griffin told the Trix that nothing can control it when they revealed their intentions of summoning it.
- In the 4Kids version, it is called the "Army of Decay".
- In the German dub, it is called "Armee des Todes", which means "Army of Death".
- Army of Darkness is also the name of the army of Deadites appearing in the Evil Dead film of the same name. In addition, the book used to summon the Army of Darkness resembles the Necronomicon from the Evil Dead series.
