Ouroboros

Ouroboros (ウロボロス, Uroborosu) is a recurring demon in the series.

History
Ouroboros is an ancient symbol depicting a dragon or a serpent swallowing its own tail to form a cycle. It is a very important religious symbol over the ages. In alchemy, it is a purifying sigil. The myth of the Ouroboros is not dissimilar to other myths of cosmic serpents, such as the Australian Aboriginal myth of the Rainbow Serpent.

Shin Megami Tensei: Strange Journey
Ouroboros is a boss in Sector Eridanus. Its name is mentioned as Ouroboros Maia, making her one of the of the three Mothers of the Schwarzwelt (alongside Tiamat and Maya) you obligatorily fight. She dwells in the Vanishing Point Chamber, in the very core of Eridanus' top floor.

Ouroboros is fought twice; in her first form, she will continually regenerate health and use Wild Thunder, a potent Lightning-type attack, and Disaster Cycle, an light physical attack against all enemies, which has the added issue of liberally inflicting any possible ailments to the targets. Overall, the first battle is mostly difficult because of her ability to replenish her health.

However, it becomes apparent Ouroboros is simply immortal in this form, forcing the Strike Team to leave; Captain Jack is the one to call the Protagonist and point him to the exact locations from which Ouroboros is drawing energy. Once the demons at these locations are dead, Ouroboros will infuriately realize what happened and enter a second and more dangerous stage when the protagonist again enters the. Chances of seeing Disaster Cycle greatly increase and Ouroboros begins using Wave of Death, a potent physical attack.

Once she dies, she will moan in agony about "the torus of eternity" being twisted, and leave behind a band of energy, pocketed by the protagonist, and her rare forma. Also after defeated, Ouroboros is unlocked to special fuse using five demons: Dzelarhons, Kwancha, Mandrake, Basilisk and Vouivre.
