Scorpio Kardia is the Scorpio Gold Saint in Lost Canvas. He was portrayed as a close acquaintance of the Aquarius Gold Saint. He held the Specter Frog Zelos as a prisoner in his temple. Kardia is introduced as a merciless sadist and a prideful, arrogant, and boastful warrior with an explosive personality. Kardia joins Aquarius D&eacute;gel in his mission to Siberia to enlist the aid of the Blue Warriors in the war against Hades.    Arriving in Bluegraad, Kardia and D&eacute;gel were attacked by the Blue Warriors, after escaping from the attack the Scorpion Gold Saint unleashes his technique known as Scarlet Needle, with which he launches a crimson needle to 14 body parts (which represents the stars of Scorpius) to poison opponents, causing bleeding and excruciating pain, losing their 5 senses in the process, upon receiving several of the blows, the result can only be either madness or death. Kardia finished opponents with Antares Needle, the killing blow of the Scarlet Needle combination.    Also, Kardia exhibits a new technique which is known as Katakaio Needle(from the Ancient Greek &kappa;&alpha;&tau;&alpha;&kappa;&alpha;ί&omega; (Katakaio), usually translated as &quot;utterly burned&quot;), used on exceptionally powerful foes, and essentially causes Kardia&#039;s opponent&#039;s blood to boil within themselves, while connected to Kardia&#039;s heart lifeforce. After successfully inflicting 14 hits, Kardia finishes the Katakaio Needle with Katakaio Antares, the fifteenth star of the Scorpius constellation, which delivers the killing stroke for his opponent.    During his fight against Rhadamanthys we discover that besides being a Saint of Athena, Kardia is addicted to fights, therefore, he fights for his own amusement. Further motivation comes from a degenerative heart disease which shortens his life, which has been treated by D&eacute;gel using his freezing ability to estabilize Kardia&#039;s heart temperature. Kardia decided to live his short life intensely, only doing what he pleases and encountering death while facing a strong adversary. His death wish is fulfilled while fighting Wyvern Rhadamanthys, who, he was able to defeat.    While presumed dead, Kardia appeared once more when Unity was escaping the crumbling Atlantis, as he helped him to reach the surface alive. When he awoke, Unity noticed Kardia&#039;s red nail in his hand, implying the Gold Saint died shortly thereafter, leaving the prince with the nail as a memento of himself, which helped keep Unity warm.
