Athena is the Greek goddess of wisdom, courage, inspiration, civilization, philosophy, justice, law, mathematics, strength, arts, crafts, weaving, skill and reason who sprung from Zeus' forehead fully armored after he swallowed her mother, Metis. She represents just decisions and strategic warfare and is the only goddess allowed to carry Zeus' thunderbolts. She led battles as the disciplined, strategic side of war, in contrast to her brother Ares, the patron of violence, bloodlust and slaughter.
She has aided numerous heroes such as Heracles and Perseus, and supported the Greeks during the Trojan War. Although her given name is Athena, she adopted the name of her friend Pallas after killing him in battle. It was at this time that Zeus gave her the Aegis, a piece of armor capable of protecting her from all evil and disaster.
She was depicted crowned, with a crested helm, armed with a shield and spear. She is commonly shown accompanied by her sacred animal, the owl. She is the virgin patron of Athens, which was named in honor of her (the Parthenon, which overlooks the city, was a temple the Athenians dedicated to her.) The Greeks especially also associate the olive with her, as she won a contest against Poseidon to decide who would be the patron god or goddess of what would become Athens when she planted an olive tree as a gift to the city.
Although Perseus' conquest of Medusa is well known, Medusa was originally a ravishing woman with beautiful hair. She was so enamored with herself that she boasted one day that her hair was more beautiful than that of even Athena. In a fit of rage, Athena turned Medusa's hair into snakes that would turn anyone who looked at them into stone. Still unsatisfied, Athena had Perseus slay Medusa and is then said to have fitted Medusa's head into the Aegis to make it even more powerful. Another version was that Medusa herself was a high-priestess of Athena. Loyal and devout, Medusa's near supernatural beauty prompted people to make attempts at wooing her and would often come to Athena's temple simply to see Medusa. Of the men who wished to have the beautiful Medusa as their own, the most powerful was Poseidon, the Lord of the Ocean who was determined to make her his own. Using his divine powers, Poseidon made Medusa enter a dream-like state in which she succumbed to his advances. Outraged at Medusa having had been seduced by her arch-enemy, Athena punished the high-priestess by transforming her into the first gorgon. As a gorgon those fair features were hideously wrought and those golden locks twisted to hissing vipers. Anyone that met her eyes was petrified, a statue for all eternity.

Pallas Athena appears as support to Thor when he acts as boss in Celu Tower's gold instance and also as a gatekeeper to Ares' floor in the Steven instance. Players can obtain the ability to fuse her by recording at least 90 demons in their compendium. She can be fused in a special fusion of Throne, Sati and Valkyrie.
Athena is Aigis' ultimate Persona in Persona 3. She is a well-balanced and versatile Persona whose real potential lies in her exceptionally high Endurance and her plethora of supportive spells, though she is also highly capable of offense and acting as an emergency healer whenever needed.
"The virgin war goddess who sprung from Zeus' forehead fully armored after he swallowed her mother, Metis. She is the patron goddess of Athons and is associated with olive trees."
—Devil Survivor 2 compendium
In Devil Survivor 2, Pallas Athena is a unique demon that doesn't require a particular fusion combination to create. Instead, the player has to achieve a Fate level of 5 with Makoto Sako before it is available. Once this has been achieved, it is unlocked for fusion on all subsequent runs as long as the player imports their save.
As an allusion to Makoto's Fate Events in the original game, Pallas Athena makes its appearance in The Animation, under the ownership of Makoto herself. The demon became available to Makoto after Fumi Kanno upgraded their cell phones to summon demons under Nicaea.
Makoto first summons Pallas Athena in a battle against Benetnasch, where it dealt major damage to its full body by impaling it in multiple areas with an unknown attack. However, she, along with the other Tamers' demons, was forced back to her owner's cell phone when Benetnasch utilized its demon-revoking frequency waves.
She, along with everyone else's demon, goes to Hibiki in episode 13. She was fused with Suzaku to make Metatron.
"The goddess of war in Greek mythology and one of the twelve Olympian gods. She sprung from Zeus' forehead fully armored after he swallowed her mother, Metis. She is also considered the goddess of skill and art, and though she is the goddess of war, would only engage in battle to protect that which she loves and never for the sake of warfare."
Athena appears alongside Izanagi, Thanatos and Messiah as one of the Personas featured in Lord of Vermillion Re: 2, once again serving as one of Aigis' Personas. She uses Orgia Mode as her skill, which increases Aigis' stats temporarily and enables her to use Heavenly Spear as her main offensive ability.
In Persona 3, Athena holds her traditional shield reflecting the head of Medusa. This shield is known as the "Aegis of Athena."
One of Kanji Tatsumi's weapons is a shield called the Aegis Shield, which has a coloration and design that greatly resembles that of Athena's signature revolving shield in Persona 3, though it no longer bears the head of Medusa. It also gives Kanji a very significant boost in Endurance (+10).
Pallas Athena is an Epithet, or a title of Athena given to her by authors or worshipers. In the Iliad, Pallas Athena was always her name. Pallas means to brandish, in reference to when Athena brandished the spear of Aegis.
The fact that Pallas relates to the Aegis Spear is a connection to Aigis, which Athena is her Persona.
