Sivoir Snyle

Sivoir is arrogant, sadistic, and enjoys attacking opponents from positions where they cannot retaliate. He repeatedly taunts Leopold Vermillion while sniping him from afar and assumes that distance guarantees his safety.

He is particularly proud of never having experienced serious injury. That confidence makes him careless once Leopold begins laying a trap across an area far larger than the point Sivoir is watching.

Sivoir uses Eyeball Magic, manifesting additional eyes that observe distant locations. Catoblepas's Evil Eye allows him to track information about an opponent's position, movements, stamina, and magical condition.

He combines that reconnaissance with highly concentrated Magic Bullets fired from his fingertip, functioning as a magical sniper who can attack from beyond an opponent's effective range.

As a Dark Disciple, Sivoir possesses Stage Zero magical power enhanced through devil power. Vanica's curse can restore severe injuries as long as its effect remains active.

Sivoir accompanies Vanica's forces into the Heart Kingdom and defeats Spirit Guardian Floga before turning his attacks against nearby civilians.

Leopold arrives and becomes his next target. Sivoir repeatedly changes position while using manifested eyes to track Leopold and fire on him from outside his range.

Leopold gradually creates a giant Mana Method array covering the battlefield rather than attempting to hit Sivoir directly. Crimson Eruption ignites the entire enclosed region, forcing Sivoir to reveal himself through his reaction to being burned. Leopold follows the sound and lands a direct attack.

Vanica's curse later restores Sivoir. She ultimately detonates the devil power inside him when withdrawing from the Heart Kingdom, turning him into an explosive magical weapon.

Vanica Zogratis commands Sivoir and supplies the devil-enhanced curse sustaining him.

Leopold Vermillion defeats Sivoir by constructing a Mana Method array too large for his long-range surveillance to avoid.

Floga is the Spirit Guardian Sivoir defeats before Leopold arrives.
