A leading Spider Rider and captain of the Arachna military. His name mirrors Magma's—when magma cools, it becomes igneous rock. Igneous is calm, gentle and has quite a strategic mind. Igneous takes Hunter's training seriously and almost acts as a mentor to Hunter, to his annoyance. He challenged Hunter and Shadow to a duel when they joined the Riders, but it was only to see if Hunter could cooperate with Shadow. Igneous was part of the Arachna Knights, where he teamed up with a long-time friend Slate. Both were known as "Claw" and "Fang" and they proved to be quite powerful, especially since Igneous didn't call his spider Flame to assist. Regardless of his grade, Igneous is proud to serve the royalty of the Arachna Kingdom, and always offer his help to prince Lumen and princess Sparkle. His weapon is a cavalry lance and one of his attacks is a flamethrower coming out of the tip of the lance. He has a crush on the Queen of Nuuma, Illuma. Igneous had a fan club of Arachna's castle's females, but while he was away to Nuuma, they had found boyfriends, leaving him crushed. He is also afraid of ghosts, but won't admit it and says they don't exist.
