Hermes While seemingly friendly, the relationship between Ares and Hermes seems to be defined by Ares trying to keep his image to his younger brother and failing, with Hermes humoring whatever Ares does and says out of politeness. Ares Despite being the Greek God of War, he is relatively weak, clueless and far more emotional compared to other Olympians. He is easily intimidated, shown by his interaction with his younger brother, Hermes, a Messenger of the Gods.
