Ophis
Being born from nothingness, Ophis rarely shows any sort of emotion, only wanting to get rid of the Great Red and return to the Dimensional Gap to obtain “silence.” Issei describes Ophis as an honest and pure Dragon who is naive. Azazel indicates Ophis has changed because of her interaction with humanity, but how is never described.
Some time in the distant past, Ophis was born in the Dimensional Gap, and lived there as its home. Eventually, long ago, Ophis left the Gap, but when it attempted to return, found that the Great Red had taken up residence there. Before assuming her current form, she used a different guise in the form of an elderly man. At some point before the start of the series, Ophis became the leader of the Khaos Brigade.
Ophis’ name was mentioned in Volume 4, in which Ddraig calls her “the strongest existence.”
She made her official appearance in Volume 6 in the Underworld to look at the Great Red before retreating.
As her name suggests, Ophis has the ability to manifest her powers in the form of snakes. These snakes have the ability to increase a person’s power tremendously by consuming it. Another type of snake she creates can be used to bring out a Sacred Gear’s full potential. While this can potentially lead them to achieving Balance Breaker more quickly, it can also break the Sacred Gear, killing the host.
According to Ddraig, her true abilities are stronger than the two Heavenly Dragons combined. So much so that when her powers are reduced to level twice as powerful as the Heavenly Dragons, she feels “weak.”
Ophis is a true shapeshifter, able to alter her size, apparent age, physical attributes/characteristics, and even her apparent gender.
Ophis can “bless” people, granting them certain advantages. These blessings don’t seem to be of a type to negatively affect Devils. With Asia, the blessing has increased her compatibility with Dragons, while with Irina, it has increased her luck.
She reappears in Volume 11 at the Hyoudou Residence along with Le Fay Pendragon, Fenrir, and Kuroka, wanting to observe Issei as he was having unusual growth of powers. Her powers were later stolen by Cao Cao and Georg who used Samael on her. At the end of Volume 11, she was kidnapped by Shalba Beelzebub with Issei rescuing her but receiving Samael’s curse as a result.
In Volume 12, Ophis and Issei were on top of the Great Red after he passed through the crumbling dimension they were both on, rescuing the two of them. She then used her powers on the Great Red’s flesh to form a new body for Issei. When Issei returned to the Underworld, Ophis guided Issei by sensing where his friends were, telling him the directions on how to get there. Following the crisis in the Underworld, she moves into the Hyoudou Residence at the end of Volume 12 to continue “observing” Issei much to the shock of the other girls, as a part of her was used to recreate Issei’s body with Great Red’s flesh.
Ophis also has the ability to unleash massive amounts of destructive power. However, since her powers were diminished by Samael, she cannot control these powers properly.
