Sachiel's A.T. Field

The Absolute Terror Field (also known as A.T. Field (A.T. フィールド, A.T. Fīrudo?)) is a barrier that both Angels and Evangelions can generate to protect themselves. A.T. Fields typically take the shape of octagonal waves of energy and are usually orange in color. The strength of A.T. Fields produced varies between Angels; for example, the Angels Zeruel and Ramiel possess extremely powerful A.T. Fields, while Matarael's A.T. Field was very weak. The strength of Evangelion units' A.T. Fields depends upon the synchronization level of the pilot, and the strength setting used at the time. Eva pilots can control the strength of the A.T. Field from their entry plug.[1]

A.T. Fields are normally invisible barriers but become visible to the naked eye when colliding with other things. They are mainly used as an almost impenetrable shield; only the most powerful weapons, such as N² Weapons are capable of breaching them. Even then, damage to the Angel is generally minimal. Through most of the series, the only things that can reliably penetrate an A.T. Field are another A.T. Field (as seen in Episode 02 when Evangelion Unit-01 "corrodes" Sachiel's A.T. Field) and the Spear of Longinus.

Some Angels are sophisticated enough to use A.T. Fields as a method of attack or movement. Sachiel, Israfel and Bardiel can be seen making jumps assisted by their A.T. Fields, while Sahaquiel and Zeruel use theirs to attack, with Sahaquiel using it to destroy satellites and Zeruel in the Rebuild to shove attackers away. Kaworu's A.T. Field is powerful enough (or perhaps his mass is low enough) that he's able to use it to glide through the air.

It is revealed later in the series that every living thing with a soul possesses an A.T. Field: Angels and Evangelions just have A.T. Fields so strong that they are easily detectable and can even stop physical attacks. The boundary within an A.T. Field is subject to different physical laws as decided by its creator, and in the case of Angels this effect is so powerful that they are able to create seemingly supernatural phenomena within the enclosure of their Field. While substantially weaker in human souls, the A.T. Field nevertheless provides a vital function: Bounding the ego and sense of self of a person from everyone else, allowing them to exist as an individual. Without an A.T. Field, it becomes almost impossible for souls to define their own existences without substantial conscious effort, causing the physical body of the soul to degenerate into pure LCL.

"This is the light of my soul. A sacred territory in which no one may intrude. Aren't you Lilin even aware that your AT field is merely that wall that encloses every mind that exists?" - Kaworu in Episode 24

Weakness[]

The Spear of Longinus, an ancient and unbreakable weapon created by the First Ancestral Race to subdue Seeds of Life, is able to penetrate any A.T. Field, no matter how strong it is.

In Transformers Mode “Eva” the A.T. Field was unable to protect an Angel from being possessed by Starscream's ghost and make the Angel his own body.

Geometric A.T. Field

The A.T. Fields appear usually as octagonal or hexagonal fields. They are often orange, though pastel purple and red ones have also been used. Rather than traditional force-fields, A.T. Fields appear to behave more like membranes that twist and tear as they are penetrated.

Rebuild of Evangelion[]

Also known as Field of Absolute Inviolability (絶対不可侵領域?). In the film series, the A.T. Fields present all of the same properties so far, and are once again used as weapons by the Evangelions.

In Evangelion 2.0: You Can (Not) Advance during the battle with Tenth Angel, the awakened Unit-01 turns its A.T. Field into a beam shot from its eyes.

In the same battle with Tenth Angel, Unit-01 creates an artificial arm with its A.T. Field, and uses it as a weapon, taking the form of a ring of geometric shapes which blast the Angel back.

Transformers Mode “Eva”[]

After possessing an Angel, Starscream was able to use the A.T. Field to block attacks from Optimus Prime who had the traits of EVA-01 after scanning it. However the Autobot's Leader was able to use his Energon Axe to channel the Red Energy from his EVA Core to tear through the A.T. Field and rip out it’s core.
