Ares

Ares is the Olympian God of war and the founder of Sparta. He and his sister Athena have been enemies for centuries and he has done everything to try and destroy her precious city of Athens. He is voiced by Jay Thomas.

Hercules
In the film he has a very minor role in which he only appears in minor cameos.

In the beginning of the film he is present for the party celebrating the arrival of Zeus and Hera's newborn child Hercules. Ares, along with the other God,s was sent to find Hercules, but it was too late as the baby had already been turned into a mortal and was adopted by a mortal family. Eighteen years later, he is seen imprisoned with the other Gods after they lost against Hades and the Titans. Luckily he and the other Gods are freed by Hercules.

Hercules (Animated series)
In the animated series he makes numerous appearances and acts as the force behind the plot in quite a few episodes. The rivalry between him and his sister Athena is introduced. Ares goes to his brother Hephaestus to forge a weapon that would be powerful enough to destroy Athens. When Hercules goes to Sparta to steal the secret weapon for Athena, Ares recruits Hercules into the Spartan army. When Athena arrives to claim the weapon that her minion (Hercules) stole, Ares and Athena get into a fight until Hercules breaks the fight and throws the Armageddon Bow landing in the hands of Cupid, the god of Passion.

Trivia

 * Ares' Roman name is Mars.
 * In greek mythology, Ares was the son of Zeus and Hera, both of whom despise him, although it's unknown, though unlikely this was the case in Disney's version.
 * Ares seems to have a poor memory, more than once he forgot Hercules was the son of Zeus, and even past encounters with him. In instances like this, Ares refers to Hercules as "Sport".
 * Ares has two sons, Fear and Terror, collectively referred to as "Ares' two mighty sons". The two are demigods, implying Ares was romantically involved with a mortal woman. Like Hercules, Fear and Terror possess immense strength, although they are very dim-witted.
