17th Angel: Tabris (Kaworu Nagisa)
SPOILER!
Final Angel · Fifth Child
Kaworu Nagisa arrives as the Fifth Child and is revealed to be Tabris, the final Angel encountered in the television series. He can synchronize with Unit-02 without entering it and deploy an A.T. Field powerful enough to cut NERV off from Terminal Dogma.
Kaworu descends believing the being below NERV is Adam, then recognizes that the crucified giant is actually Lilith. Rather than continue toward a result that would destroy humanity, he asks Shinji to kill him.
Why it matters
Episode 24 turns the Angel conflict into a choice rather than another battle. Kaworu is both the enemy NERV has been waiting for and the first person to offer Shinji acceptance without demanding performance in return.

18th Angel: Lilin (Mankind)
SPOILER!
Humanity · The Lilin
Kaworu calls humanity "Lilin," connecting human beings to Lilith rather than to Adam's line of Angels. The television series uses the term to reframe the conflict: the creatures NERV calls Angels are not simply invaders attacking an unrelated species.
The later film continuation makes the "humanity as the final Angel" framing more explicit than episodes 1–26 do.
Why it matters
By the end of the series, the boundary between "human" and "Angel" is much less comfortable than it was in episode 1. The conflict is about competing forms of life and the barriers that keep individual beings separate.
