Character from House of the Dragon by George R.R. Martin
The Blood Wyrm — Daemon Targaryen's dragon, a lean, red, vicious creature built for killing rather than beauty, the only dragon fierce enough to challenge Vhagar and win, at the cost of his own life.
Caraxes is Daemon's dragon in every meaningful sense — not just his mount but his mirror. Where Vhagar is ancient patience and overwhelming force, Caraxes is speed, aggression, and controlled fury. He is not the largest dragon, nor the most beautiful, but he may be the most dangerous pound-for-pound, because he fights with a viciousness that borders on suicidal — which, at the Gods Eye, it literally was. He was already a veteran war dragon before Daemon claimed him, having been ridden previously in the Stepstones campaign. His long neck and lean frame make him faster and more maneuverable than larger dragons, and he fights with a serpentine striking style — coiling, lunging, clamping his jaws and refusing to release. At the Battle Above the Gods Eye, he dove onto Vhagar from above, locked his jaws around her neck, and drove them both into the lake. He crawled onto the shore afterward, eviscerated and dying, and expired on the bank. It was the most Daemon thing a dragon has ever done.
Long, lean, and serpentine where other dragons are broad and heavy. His scales are blood-red, giving him his name. His neck is unnaturally long, his body narrow, his wings enormous relative to his frame. He looks wrong — stretched and sinuous, more wyrm than dragon, built for speed and savagery rather than the majestic proportions of his kin. His eyes burn with a predatory intelligence that suggests he enjoys killing as much as his rider does.
