Ares
Ares is the god who thrives on violence and battle, not thinking of the consequences, but only of spilt blood. This is the god of war.
Ares has a certain, ‘eerie’ feel to him. While he comes across as handsome and bold, there is an atmosphere of cruelty and malice that surrounds Ares, which is probably why he is the most loathed among the gods. It is said that even Zeus, his own father, dislikes Ares.
Through all the dislike, Ares still reproduced, and is father to Diomedes, Cycnus and Oenomaus.
Ares employs no thought before action, as he is pure testosterone. He lives for the moment, for battle and for death.
When you hear all of this about Ares, you would picture a great warrior who knows no fear, but this is not the case, as Ares has often been seen to flee a battle like a coward, specifically during the Trojan War when Diomedes stabbed him with a spear.
Ares holds the vulture as his sacred animal, as the vulture represents death.
Overall, Ares was not a great god in Greek mythology, but his equivalent in Roman mythology, Mars, earned much more respect.
