Igneous commands as a captain within the Spider Riders and serves as a command officer for the Arachna Royal Military. He possesses indigo hair and hazel eyes. His civilian outfit features a black long-sleeved shirt beneath a faded yellow shirt, a white scarf draped across his chest, a white belt, black pants, and black boots. His Spider Rider armor incorporates gold plating on the left shoulder, a white cape, a long white glove on the left arm, and distinctive white-and-gold boots. Personality-wise, Igneous typically exhibits calmness and strategic thinking, though with occasional flashes of a short temper. He upholds a strong sense of honor and reacts poorly to disobedience. A notable personal quirk is his fear of ghosts, which he staunchly denies exist. He acts as a mentor to Hunter Steele, rigorously overseeing his training. Early on, he challenged Hunter to a duel solely to test the boy's ability to cooperate with his spider partner, Shadow. Details of his background, including family, home village, or how he discovered his battle spider, Flame, remain largely undefined; the official Japanese website places his age between 17 and 19. As a warrior, Igneous possesses considerable strength and fulfills his duties with unwavering dedication to protecting Arachna and the Spider Rider team. Relationships are central: his oldest and closest bond is with the Arachnian knight Slate, forming the renowned fighting duo "Arachna's Claw and Fang" – Igneous as "Fang" and Slate as "Claw". He holds deep loyalty toward Prince Lumen and Princess Sparkle. Romantically, he develops feelings for Queen Luuma (also known as Illuma) of Nuuma. Previously, he enjoyed significant popularity among females in Arachna Castle, who formed an "Igneous Club" fan club; however, during his mission absence in Nuuma, the members found boyfriends, to his disappointment. His battle spider, Flame, ranks among his closest companions. Additional friends and allies include Hunter Steele, Magma, Grasshop, Shadow, Ebony, and Queen Luuma herself. His name carries an ironic origin, derived from igneous rock (formed from cooled magma) – the latter being the name of another Spider Rider. In combat, his primary weapon is a cavalry lance capable of unleashing a flamethrower attack from its tip.
