Isis

Isis (イシス, Ishisu) is one of the recurring demon in the series.

History
Isis was a goddess in Ancient Egyptian religious beliefs, whose worship spread throughout the Greco-Roman world. She was worshiped as the ideal mother and wife, patron of nature and magic; friend of slaves, sinners, artisans, and the downtrodden, as well as listening to the prayers of the wealthy, maidens, aristocrats and rulers.

The goddess Isis was the first daughter of Geb, god of the Earth, and Nut, the goddess of the Overarching Sky, and was born on the fourth intercalary day. Isis was said to have literally blackmailed the true name of Ra the supreme sun god out of him, by making a snake poison him, which could only be cured by Isis herself. (Ra, being a god, cannot die from the poison, but the pain would still last) In later myths about Isis, she had a brother, Osiris, who became her husband, and she then was said to have conceived Horus. Isis was instrumental in the resurrection of Osiris when he was murdered by Seth. Her magical skills restored his body to life after she gathered the body parts that had been strewn about the earth by Seth.

Digital Devil Saga: Avatar Tuner
Isis serves as the boss of the Green configuration of the Brutes Base in Ajna. A gimmick used during the boss fight with her is that she will respond to any element case against her during a turn by casting a single target -dyne spell of an element used back at the party. This can be used to the party's advantage by only using one type of element and having a Shield spell ready to block the retort.

Isis can also use Reiforcements to summon up to two other Isis demons. Together they will start using enemy combo elemental spells. Two Isis demons will use multi-target -dyne spells such as Maragidyne. The full group of three will use stronger elemental combos such as Trisagion.

Devil Survivor 2
In Devil Survivor 2, Isis 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 Hinako Kujou before it is available. Once this has been achieved, it is unlocked for fusion on all subsequent runs as long as the player imports his/her save.

Persona 4 The Animation
Isis represents the bond between Yu and Margaret in Persona 4 The Animation. She was summoned after Izanagi took serious damage from Ameno-sagiri's attacks, and Yu being stuck under huge rocks. Her levitation abilities assisted Yu in getting back up once again.

She is one of the two Ultimate Personas that Yu summoned that was not created through fusion, the other being Sraosha.
