Cyanor, localized from Naaza in Japanese media and Sekhmet in the English dub, serves as one of Emperor Talpa's (Arago's) four primary Dark Warlords, bearing the title Venom Warlord. His Armor of Venom, also called the Snake Armor, represents Autumn and embodies the virtue of Obedience, granting him powers centered on poison and serpentine abilities.

Acting as the secondary antagonist in the initial story arc, he is the second Dark Warlord dispatched to confront the Ronin Warriors. His primary narrative focus involves direct opposition to the Ronin Warrior of Water, Cyrus Mouri (Shin Mouri). Cyanor employs venomous attacks and utilizes the serpentine traits of his armor in combat.

Under specific conditions or when accessing his full power, Cyanor transforms into his true form, manifesting as a giant naga, which amplifies his serpentine connection and combat capabilities. He can also assume the full form of a snake.

Cyanor meets his demise at the conclusion of Season 1 during a confrontation, succumbing to an enemy attack.
