-Talpa, Leader of Darkness-
Once a human, Talpa was so evil that, upon his death, his soul was sent into the demon realm, where he was able to subdue its demon residents with his terrible evil. Talpa became lord of the demon realm, and master of his demon army, the Dynasty. Not satisfied, Talpa entered our world to claim it as well, but was defeated by the Ancient. Four hundred years later, when the world's spirituality had declined, Talpa chose to return, taking the form of a giant floating head. After sending his Dark Warlords out to combat the Ronin Warriors, Talpa decided that he had to do the job himself. Talpa absorbed the powers of all nine armors, giving him back his physical form, back in full armor. He was ultimately defeated by the power of the Inferno armor, and returned to the demon realm. There, he staged a second attack, mainly focused on obtaining the three ancient artifacts: the Inferno armor, the Soul Swords of Fervor, and the Jewel of Life. He was finally destroyed with the goodness of the Inferno armor, combined with the four Ronin Warrior's powers and the Jewel of Life.
-Sarenbo, a real pain the the ____-
A moon demon sent by Talpa to discover the extent of the Ronin Warriors' power, Sarenbo was so powerful that he provoked the first manifestation of the white armor of Inferno, the first weapon essential to defeating Talpa.
-Lord Saberstrike, Master Swordsman-
Servant of Talpa, Lord Saberstrike is sent to stop the Ronin Warriors from attaining the Soul Swords of Fervor, essential to harness the power of Hariel's white armor of Inferno, and the second mystical weapon with which Talpa could be defeated. Accompanied by an armored black tiger named Black Blaze, Saberstrike beats the Ronin Warriors to the Soul Swords. His code of honor made him give one of the two swords to Ryo, so they would be evenly matched. Ultimately, Saberstrike was defeated. With his defeat, the Ronin Warriors received the second Soul Sword, and the injured White Blaze was revived with the spirit of Black Blaze. Lord Saberstrike's "parting gift" enabled White Blaze to transform into Black Blaze to carry the White Armor's Soul Swords of Fervor.
-Sun Devil, another pain in the ____-
This demon could create black ice, and was sent after Ryo. Not much else is known
-Dara, second Swordsman-
An inhabitant of Talpa's demon realm, Dara was given a sword formed from the combined powers of the captured Kento, Sage, and Cye, and led a large demon army to destroy the remaining Ryo and Rowen.
-Badamon, master of spirits-
Talpa's mystic sorcerer, Badamon knows much about the Ronin armors, and devises many schemes to place the white armor of Inferno under Talpa's control.
-Gashura the third pain in the ____-
Gashura was a demon sent to prevent Anubis, Mia, and Yuli from attaining the Jewel of Life, the third weapon essential to destroying Talpa. Anubis killed Gashura with the Ancient's staff.
-Demon Army, a dime a dozen-
These empty suits of armor created by Talpa are the generic henchmen to carry out the Dynasty's dirtywork. When these warriors are defeated, their spirits flow from their wounds in the form of black smoke.
-Demon Spirits, wimps in my opinion-
These flying demons are the spirits of deceased evil humans. The spirits are channels for Talpa's evil energy, and can also play magic flutes, the music of which prevent the Ronin Warriors from calling upon their armor.
