Adamas was self-absorbed and violent. He became furious upon knowing that his youngest brother, Zeus, would be the King of Olympus. To prevent this, he gathered an army of the enemies of the Greek Gods, such as the Titans, Gigantes, and the monster Typhon. He's also very short-tempered, as seen when he attacked Poseidon when he insulted Adamas. But despite his short-comings, he was extremely charismatic. Before being stopped by Poseidon, he had managed to gain the support of 49 members of Zeus' council and (with Hermes' help) a number of the twelve Olympian Gods' support and loyalty.Among his brothers, he loves Hades unconditionally and has an unbreakable faith in his skill. His death at the hands of Qin Shi Huang is enough to make him try to kill the Chinese Emperor after the fight was over. When he finds Brunhilde and Göll, and sees they're not willing to reveal to him where Qin Shi Huang was recuperating, he almost kills them until Beelzebub appears in time to stop him and discourages him from taking his revenge by telling him Hades would have never approved something like that. This convinced Adamas to stop, but not before promising he would take his revenge on the Valkyries and Qin Shi Huang as soon as Ragnarok would finish. Despite his violent demeanor he does show some care for others in his own way. Such as rooting for Beelzebub in his match against Nikola Tesla, threatening to kill him if he dies. And later trying to calm him from his rage during his confrontation with Odin.
