"Are you prepared? Are you prepared to make a choice of releasing a never ending calamity, with hope as the last remain? Are you prepared to cease being a doll and choose the future by your own will? If you are, then call my name. I am thou, thou art I. My name is... (Sophia) Pandoraaa!"
Also known as Anesidora, she is the first human woman of Greek mythology, being born from clay. The gods gave her a husband and several gifts, including a jar (or a box in modern interpretations) which she was warned not to open. Tempted, she opened the jar, which unleashed all of the evils of mankind. Only hope remained in the jar after she closed it.
Pandora is Maki Sonomura's ultimate expression of nihilism. After the death of Takahisa Kandori, Aki awakened Pandora only to have Pandora devour her, destroying her half of the other Mikage-cho in the process. Pandora then proceeded to steal the core of the DEVA System from the real world. After the protagonist and the "Ideal Maki" come in contact with the soul of the "real" Maki in the Sea of Souls and receive her compact, the party is able to enter the Avidya World and confront Pandora, who plans to use the DEVA System core in a bid for destruction of all reality. After she is defeated, she questions how the party could be so powerful, and is reminded that they are fighting together as friends and that she isn't alone. Her and the Ideal Maki then merge, and one by one the party members are sent back to the real world. As Pandora represents the negative and repressed qualities of her host and can be accepted and reformed, she can be considered as a prototype of a Shadow Self.
She manifests as a monstrous, multi-limbed lump of flesh with Maki's head poking out of the main body, although after this form is defeated it is revealed to be a cocoon for her true form, which appears as a giant version of Maki with butterfly wings and antennae.
Pandora is a member of the Tyrant Order in Megami Ibunroku Persona, but her Order was changed to Deity in both the Japanese and English versions of Shin Megami Tensei: Persona.
Pandora is the true form of Sophia's Persona. Once snapping out of Ichinose's control and recovering from her fatigue, Sophia dashes out to block Ichinose's ray cannon, before trying to convince her that the heart is important to assessing humanity. Once Ichinose was remindered of her past where her parents died, she shut down her emotions, and creating Sophia only to ditch her quickly because she had a heart, Sophia proceeds to state that she was her first friend, before writhing in pain as her face displays the words "PANDORA". Once this happens, all four Pithos merge into one, revealing their true form, Pandora within them. Sophia proceeds to fight Ichinose with the party, who was now severely and desperately in denial. Ichinose then summons a Hecatoncheir to fight the party as a last ditch attempt to kill the Thieves, only to fail and be convinced to actually turn on the Phantom Thieves' side.
