Leliel

Name: Leliel, Angel of the Night
Classification: The Twelfth Angel
Appears in Episode: 16

Leliel is the Twelfth Angel, and is among the most bizarre of the Angels. It's physical form is composed of two parts, a black spherical floating object and a large 'shadow' on the ground. However it is the spherical object that is in fact the Angel's shadow, while it's main body is the 680 meter in diameter and 3 nanometers in thickness shadow on the ground.

While previous Angels used their AT Fields to repel or block incoming fire, Leliel instead uses an inverted AT Field to consume. It's main body, while only 3 nanometers in thickness, is an area of space that can only be characterized by abstract mathematics. Ritsuko Akagi calls this area a Sea of Dirac, which she suggests to be an alternate dimension or universe. It is by drawing objects into this area that Leliel proves to be an extremely dangerous opponent, consuming large portions of New Tokyo-3 and Evangelion Unit-01 itself.

The very nature of an inverted AT Field prevents Evangelion Unit-00 or Evangelion Unit-02 from attacking the Angel directly without being consumed by it. Eventually Ritsuko Akagi comes up with a plan to use the remaining two Evangelion Units to disrupt Leliel's inverted AT Field, while bombarding it's main body with N² Weapons. This plan is never realized however.

Few details are available pertaining to the relationship between the Angel's main body and the spherical shadow it casts into the sky, however it is often described as a type of corridor that links the Angel's internal space to real space (this is based on the disappearance of the shadow when attacked). Basically, when the sphere vanishes, the corridor into it's internal space opens, consuming everything that touches the Angel's main body. Thus Leliel's most distinguishing characteristic is the fact that everything about it is inverted, it's AT Field, it's shadow, it's form of attack.

Leliel's absorption of Evangelion Unit-01 into itself has also triggers fears among the Human Instrumentality Committee and SEELE that the Angel may have attempted to make contact with the human mind, in this case Shinji Ikari, the Third Child and pilot of Evangelion Unit-01.

In what is considered to be one of the bloodiest and most disturbing episodes of the series, Leliel is destroyed by a berserk Evangelion Unit-01 as it literally rips the Angel apart from the inside out. This happens only after Evangelion Unit-01 runs out of internal power while still trapped inside the Angel, leaving the pilot Shinji Ikari on the brink of death.
