Camus was born in France and trained in Siberia to become a Saint. Rather than stay full-time at the Sanctuary, he chose to return to Siberia to train other potential Saints. In the manga, he is the master of Cygnus Hyoga and Kraken Isaac. In the anime, his pupil is the Crystal Saint.
Major Story Arcs
During the Bronze Saints' siege of the Twelve Temples, Hyoga was transported to the Libra Temple by the Gemini Saint's "Another Dimension" technique. Camus was there waiting for him, to test his strength. He told Hyoga that until he was able to let go of his emotional attachments, he would never be able to raise his Cosmo to the level of a Gold Saint. With a long-distance strike, he sunk the ship on which Hyoga's mother was buried to the bottom of the ocean, where it could never be reached. Enraged, Hyoga attacked his master. Camus was diappointed with his student's power, and trapped him in an unbreakable coffin of ice. It was his way of showing mercy to Hyoga, rather than letting him be killed by another Gold Saint.
Once Hyoga had been freed from the Freezing Coffin by Shiryu and the Libra Cloth, he challenged Camus again in the Aquarius Temple, who again encased him in ice. Hyoga raised his Cosmo and broke out of the coffin, and Camus realized that he had no other choice but to kill him. He used his ultimate technique, "Aurora Execution." Hyoga survived and attempted to fight back, but Camus told him that only a temperature of 0 Kelvin (absolute zero) could freeze a Gold Cloth, and to achieve that, he would have to surpass Camus' own power. Hyoga copied the Aurora Execution move, and the two used them against each other. Hyoga's attack reached absolute zero, allowing him to defeat Camus, though he too was gravely wounded. Camus soon died of his injuries, proud that his student had surpassed him, and had become an honorable Saint.
Camus and the other Gold Saints who died in the war for Santuary were revived as Specters, servants of Hades, wearing dark versions of their Cloths, called Surplices. Determined to take the head of Athena, Camus, along with Gemini Saga and Capricorn Shura, advanced to Virgo Shaka's temple. Each of the three dead Saints had four of their five senses destroyed by Shaka, and decided to use their last resort--Athena Exclamation, a forbidden attack that required the power of three Gold Saints. Camus was reluctant to use it, knowing that it would erase all of their honor as Saints, but agreed to it in the end. The three then used the attack again against the Athena Exclamation of Leo, Aries, and Scorpio. The opposing forces would have leveled the Sanctuary had the Bronze Saints not redirected the energy upward.
Camus arrived with the other dead Saints at Athena's temple, determined to kill her. Athena chose to commit suicide, and it was revealed that the three Saints had fooled Hades as part of a plan to revive Athena's Cloth. They regretted having had to kill Shaka, but it was necessary to convince Hades that they were loyal. Upon their return to the underworld, the three planned to kill Hades, and they threatened Pandora that they would kill her if she did not take them to her master. However, the dead Saints' twelve hours of life were up, and their souls returned to Hell before they could accomplish their mission.
Athena's power later revived Camus and the other Gold Saints, and he gave Hyoga a few words of encouragement before sacrificing his life along with the others to destroy the Wailing Wall blocking the entrance to Elysium.
Powers and Abilities
Camus' peak human strength, speed, stamina, and defense are augmented by his Gold Cloth. All of his techniques are ice-based. "Diamond Dust" is the simplest, just a blast of snow/ice, and also the weakest. The ultimate attack of the Aquarius constellation, "Aurora Execution," though similar, is much more powerful. "Freezing Coffin" is the technique Camus uses to encase his enemy, still alive, in a nearly unbreakable block of ice.
