The God of War is a source of great difficulty for the Theoi. Technically the crown prince, he is unloved by Zeus, and his fragrant disregard for his brother's marriage to Aphrodite leaves Hera appearing less powerful than she would desire, not able to keep her son of husband faithful. He is a monster on the battlefield of Troy, so much so that Athena must guide the Hero Diomedes to strike him so that he will flee the field.
It might be important to note that while Ares is a screaming and roaring God of violence and battle, Ares is... challenged in the realm of fighting. Several times when Ares is forced to test his physical capacity at combat, such as against Heracles, or when he is trapped in a jar, Ares falls short. Just why this is, Scions might wonder, as one would expect the Pantheon's God of violent war to, well, be good at fighting.
But, as the Greeks saw Ares as someone disliked and mistrusted, the Romans saw him as one of their great patrons as Mars. The father of their founder, Romulus, and patron of the armies that which they brought about one of the most influential Empires that the world has known. The Romans painted Mars as a protector, a staunch guardian of his people, and of Rome herself. Something which raises the question, who was wrong? If either of them even were.
Incompetent God
One probably asks, "Why is Ares terrible at actually fighting people?" which is a very good question. It is theoretically is job as War God to fight people, however, he fails almost every time he comes into conflict with another being.
The reason for this probably has something to do with a fall in the popularity of Ares compared to Athena. In the archaic period, single combat between champions appears to have been prevalent, shown by the Iliad. However, in the Hellenistic period, this changed to a focus on the phalanxes of the polis. This change in method likely explains the fall of Ares and the rise of Athena who represent these two different methods.
