Appearance

Gregor is an exceptionally tall, horned Sarkaz usually concealed in heavy black armor. In Kazimierz, his silhouette and armor earned him the public identity of the Black Iron Knight. 101 107 183

• Stands roughly three meters tall in armored form. 183
• Wears dark, imposing armor that conceals his body and face; his horns remain visible. 99 107
• Often mounts Ten Percent Off, a television-like robot, on his head as a translator. 87 99
• His heat can distort the air and melt footprints into reinforced arena flooring. 107
• In his Cytoplasm form, he has a pale, robust humanoid body with black flames in place of a head; cross-shaped starlight serves as his pupils. 192

Personality

Gregor is direct, protective, and often uncomfortable with attention or complicated social situations. He is notably poor with directions and reading, but does not disguise either weakness when help is needed. 101 104 106 174

He distrusts uncontrolled strength. Though overwhelmingly powerful, he deliberately develops restraint and worries that berserk power can only lead to slaughter. His concern is not merely for himself: he fears losing control would leave him unable to protect his companions. 42 123

His compassion extends to people society has discarded. He provides food to Sector Zero’s Infected children, seeks a path to improve the Infected’s circumstances, protects frightened tournament contestants without killing them, and believes kindness deserves a proper response. 113 132 183 193

Abilities & Skills

Energy Shield

Gregor’s Paladin skill creates a defensive domain that erases incoming projectile attacks.

• Can expand into a spherical field that neutralizes attacks before they reach him or nearby allies. 104
• Ordinary bullet spells are erased at the field’s boundary. 204
• Absorbing too much damage increases the danger of his power entering a berserk state. 204
• The Grand Knight’s domain demonstrated that his shield can protect allies within its area, not only himself. 123

Holy Shield and Paladin Armament

Following his duel with the Grand Knight, Gregor’s original Paladin shield transformed into a knightly sword and full-body shield. 123 124

• Uses the shield for both defense and offense, applying swordsmanship principles through shield strikes and redirections. 153
• Can form weapons from lava, including a battleaxe. 123 125
• Uses the Holy Shield to protect allies from large-scale attacks, including Vane’s Supernova. 208

Flame Demon Physiology

Gregor can generate extreme heat, flames, and molten lava, with his body enlarging as his power rises.

• Melts weapons lodged in his body and withstands sustained attacks in the arena. 107
• Releases flames forcefully enough to drive back crowds of reporters. 108
• Can enter a massive Flame Demon state for high-intensity combat. 125
• Must manage his energy carefully to avoid losing control. 42 123

Fire Grand Knight Command

Gregor can revive Fire Grand Knights from monster cores and command them with exceptional responsiveness.

• A revived Fire Grand Knight follows simple orders such as moving, stopping, and attacking designated targets. 124
• His summons respond more quickly and precisely than Vera’s comparable revival. 124
• He later absorbs and deploys Fire Grand Knights as a force to contain riots throughout Kazimierz. 190

Special Vision

Gregor possesses a perception ability that detects hidden threats and abnormal energy.

• Sees through a Shapeshifter’s disguises. 99
• Uses energy vision to scan occupied rooms and assess danger. 105
• Detects hidden attackers and rising heat beneath a road before an ambush can strike a convoy. 143

Melee Projectile Reflection

Gregor can reflect projectile spells by striking them with a melee weapon.

• Reflected Hex Staff arcs back along their original path after being cut with his sword. 204
• Uses the same principle against Witch King remnant casters, returning their Arts attacks to their source. 214

Spartan Kick

As Beheaded, Gregor can perform an invincible flying kick.

• The kick launches enemies away; collisions with walls or other targets cause additional damage. 206
• Its invincibility window lets him create openings against stronger opponents. 206

Healing and Restorative Medicine

Gregor can provide powerful healing through both a magical Sarkaz technique and potions.

• Restores Saria’s severed arm with a magical Sarkaz technique. 105
• Provides a potion that rapidly heals Cyril Nearl, whose recovery is confirmed by medical examination. 152
• Prioritizes medical resources for Ifrit’s condition when possible. 101 204

Equipment

• Ten Percent Off — Television-headed robot used as Gregor’s translator; also used by Ifrit for music and cartoons. 45 100
• Holy Shield — Paladin shield transformed through the Grand Knight’s farewell into a knightly sword-and-shield set. 123 204
• Dark Grand Knight’s Sword — Sword associated with the Dark Grand Knight’s martial skill; Gregor uses it for his duel with Jian. 193 204
• Black armor — Conceals his appearance, protects his body, and can reshape into more ordinary knight armor. 99 110
• Monster cores — Stores energy in Fire Grand Knight cores, maintaining a reserve of 100. 124

Relationships

• Ifrit — Gregor’s ward and closest responsibility in Kazimierz. He seeks Inhibitors for her, protects her from reporters, and respects her right to decide where she lives. 101 105 108
• Saria — Initially confronts Gregor over Ifrit’s custody; they reach an understanding centered on Ifrit’s welfare. Gregor later heals Saria’s arm and works with her to treat Cyril Nearl. 105 143
• SilverAsh — Travel companion and friend. SilverAsh brings Gregor to Kazimierz, assists with his registration, and remains his ally despite knowing his identity as the Flame Demon. 100 101 105
• Jian — The Black Knight and Gregor’s eventual traveling companion. They first meet while capturing Rom, later duel as champions, and leave Kazimierz together. 104 193
• Vera, Gorth, and Vane — His siblings and core companions. Gregor acts as their cautious backbone, prioritizing their safety and coordinating their dungeon expeditions. 42 208
• Shintelaiya — Hired guide who later offers to serve as Gregor’s driver and bodyguard for protection from the Armorless Union. 111 112
• Sona — Infected leader of a Sector Zero community. Gregor earns her trust by feeding the children and later agrees to enter the arena ahead of her to keep her safe. 113 175
• Margaret Nearl — Sparring partner and student in martial technique. Gregor challenges her overly straightforward style and helps inspire her adaptation of swordsmanship to the lance. 153 161
• Ebenholz — Young Count of Utica whom Gregor protects from the Witch King remnants. Gregor encourages him to grow and live well, then arranges martial training under Jian. 221 236
