Wings of Light
The Wings of Light (光の翼, hikari no tsubasa） appear in the TV Series and in the movies Death and End of Evangelion. They appear during both Second Impact and Third Impact. During Second Impact, Adam produces white Wings of Light and during Third Impact, Evangelion Unit-01 produces white ones. While these are transparent, the wings that Rei/Lilith produces during Third Impact are white and opaque, almost as if they were an extension of her physical body.
The most obvious symbolism is that of the Christian Angels who are often depicted with wings.
Although the true purpose of the Wings of Light are unknown, both occur during an event where souls are involved. Presumably during Second Impact, the souls of the Katsuragi Expedition's team can be seen floating around when Adam spreads Wings of Light. During Third Impact, the souls of everyone on Earth are collected.
In Rebuild of Evangelion
Wings of light are possessed by the four Adams of Second Impact and are later developed by Eva-01 at Near Third Impact during its transformation into a luminous being. When Misato observes the latter, she comments on the similarity.
