The giant
crucified on a
red cross in the depths of
NERV HQ. Its face is covered with a mask on which
SEELE's coat of arms is painted, and its hands are bolted to the
cross. Although its lower body was missing while
pierced by the
Lance of Longinus, its lower
body grew back as soon as the
Lance was pulled out. The
Instrumentality Project originally planned to use Lilith, but the loss of the Lance caused
SEELE to change the plan and attempt
complementation using
Eva-01 instead. At that time,
Keel Lorentz says that
Eva-01 is
"Lilith's clone", which apparently indicates that
Eva-01 was made by
copying Lilith.
Incidentally, rabbinical scripture states that Lilith (Lilit) was the first wife of Adam, and also that between Adam and Lilith were born demons and spirits.

The
Eva Carddass Masters A-17
Angel card is titled "
2nd Angel Lilith" and the small print at the bottom of the card translates to the following.
"A Source of Life Angel called/named 'progenitor' like Adam. Until being noticed by Kaoru Nagisa, Nerv had misrepresented the giant crucified in Terminal Dogma as Adam, but it was actually Lilith. Rei Ayanami is a being with the soul of this Lilith and (a copy of) the body of Yui Ikari."
