(リリス Hebrew: נדה ,לילית xxiv folio b) is designated as the SecondAngel. Like Adam, Lilith is a Seed of Life, created by the First Ancestral Race billions of years ago. Thus, Lilith is actually a co-equal being to Adam. The other Angels are the progeny of Adam, but Lilith is the progenitor of the “Lilin”: humans. Thus it is actually somewhat misleading that Lilith has been designated as the “Second Angel”, and indeed strictly speaking, it would be proper to say that Lilith is not an “Angel”.
Billions of years ago, Lilith’s “Black Moon” transport vessel collided violently with Earth, purely by accident, in the event known as “First Impact”, creating Earth’s Moon. Lilith’s own Spear of Longinus is presumed to be destroyed in the crash. Earth already had a Seed of Life present on it, Adam, but no two Seeds are meant to land on the same planet. However, because Lilith’s Spear of Longinus was destroyed, the only remaining Spear on the planet – Adam’s – activated to try to fix the situation, and reduced Adam to a state of dormancy. Lilith then spread the primordial ooze from which “normal” terrestrial life on Earth evolved over the course of billions of years (bacteria, dolphins, monkeys, etc.), which culminated in the human race. Thus Lilith’s progeny, humanity, usurped the place of Adam’s progeny, the Angels, as the dominant race on Earth.
For countless ages, the Black Moon containing Lilith was embedded deep within the Earth, and due to shifting tectonic plates, the subterranean Black Moon eventually moved to a position underneath what would become known as Hakone, Japan, forming the massive, underground cavern that would be termed the “GeoFront”.
At some undetermined point in the recent past (possibly even beforeSecond Impact) the Black Moon and Lilith were discovered by SEELE.Gehirn (later, NERV) headquarters and Tokyo-3 were built around its position. Lilith was kept crucified to a giant cross in the deepest and most secret level of NERV HQ, Terminal Dogma, and used as a renewable source of LCL for the Evangelion Units (LCL in fact being Lilith’s blood). SEELE and NERV used Lilith for various experiments, then intentionally let Lilith grow to a point just before it could be used to initiate Instrumentality (for the sake of convenience), but then halted its growth by impaling it on the recovered Spear of Longinus which had been paired with Adam. Thus, Lilith would be ready to use in initiating Third Impact as soon as the other components needed for the process were in place.
The Evangelion Units were created by making clones of Adam, with the sole exception of Evangelion Unit-01. Unit-01 is the only clone of Lilith (hence, it is the “Test-Type”). Still images in Episode 23 suggest that instead of merely taking genetic samples from Lilith, Evangelion Unit-01 was created by physically tearing away from the lower half of Lilith, forming itself from the body mass of Lilith’s legs (explaining its legs’ conspicuous absence) and tearing away from Lilith trailing tattered ropes of flesh, in a mockery of the natural birth process.
