Like all other Gods, Ares is very arrogant and despises Humanity, to the point that when Kojiro Sasaki managed to kill Poseidon Ares was struggling to understand how a Human could kill a God. Despite being the Greek God of War, Ares is relatively weak, incapable, and much more emotional than the other Olympus Gods. He is easily intimidated, as demonstrated by his interaction with his younger brother Hermes, the Messenger of the Gods, and often displays genuine fear when seeing powerful attacks from Ragnarok's contestants. Ares is not someone who likes pranks, and he constantly scolds Loki whenever he plays one on him. Despite his flaws, Ares respected Heracles and considers him his best friend due to his indomitable will, and throughout the Fourth Round he placed great trust in him. He also knows how to be humble, as he admitted to Loki and Hermes that Heracles became stronger than him after his ascension to Godhood. He cares so much about their friendship that he is jealous that Prometheus is also friends with Heracles. After Heracles' death, Ares burst into tears and, to honor him, promised that he would fight to the end. "People of Thebes, reflect upon your sins. Surrender yourselves to the justice of the Gods."
