Well as For Eva Unit 1 (And Shinji, the pilot). In this scene of the Rebuild movie, Evangelion 2.22,The Eva is basically becoming god like. Why? To fulfill Shinji's wish of bringing character Ayanami Rei back. She died earlier in the movie, hence why this angel, Zeruel looks feminine. The angel absorbed, and or killed Ayanami. Now what force could bring back a dead person, or thing? Only a god really. This is why I said Eva Unit 1 on the verge of second impact.
