Mars/Ares
Ares(Mars in Roman mythology), the Greek god of war, is tall and handsome, but vain and as cruel as his brother Hephaestus was kind. His sister Eris, the goddess of strife, is his constant companion, but he is also attended by his sons Deimos and Phobos, as well as Enyo, an old war-goddess.
You can see the similarity with Sailor Mars there. While Ares' sons are Phobos and Deimos, Mars' crows were Phobos and Deimos. Sailor Mars is known for her martial arts and temparemental personality, a parallel to Ares' attribute to strife and war.
When Ares heard the clashing of arms, he grinned with glee, put on his gleaming helmet, and leapt into his war chariot. Brandishing his sword, he rushed into the thick of battle, not caring who won or lost as long as blood was shed. A vicious crowd followed at his heels, carrying with them Pain, Panic, Famine and Oblivion.
Once in a while, Ares was wounded. He was immortal but whenever he would get hurt he would run back to his father, Zeus and was healed. Needless to say, Zeus was very disgusted with his son. Ares was mainly worshipped in Thracia, a region known for its fierce people.
