Phoenix

The ashes of a phoenix is found out to be what will be needed to kill Eve, the Mother.

A phoenix is a mythical bird that is a fire spirit with a colorful plumage and a tail of gold and scarlet (or purple, blue, and green according to some legends).

The Phoenix's ability to be reborn from its own ashes implies that it is immortal, though in some stories the new Phoenix is merely the offspring of the older one. In very few stories they are able to change into people.

Originally, the phoenix was identified by the Egyptians as a stork or heron-like bird called a benu, known from the Book of the Dead and other Egyptian texts as one of the sacred symbols of worship at Heliopolis,

The Phoenix has long been presented as a symbol of rebirth, immortality, and renewal.
