Neon Genesis Evangelion
Kaworu appears for a very short time in the original series. In episode 24, he appears sent by SEELE to begin the Human Instrumentality Project while posing as the Fifth Child and replacement for Asuka Langely Soryu. His goal is to make it to Terminal Dogma, where he believes Adam is held, and unite with his to begin Instrumentality. Along the way he meets Shinji Ikari and the two become quick friends. The higher ups at NERV quickly become suspicious of Kaworu based on how high his synchronization rates with the EVA unit were right off the start and they quickly suspect him to be the final Angel. Their suspicions are confirmed when Kaworu, revealed to be the Angel Tabris, takes EVA-Unit 02 and uses it to force his way past NERV's defenses and into Terminal Dogma. Shinji Ikari is called to stop Kaworu, but initially refuses to believe his friend is an Angel. He comes to the realization and gives chase in Unit 01. He is unsuccessful in stopping him and Kaworu reaches Terminal Dogma but is shocked to find the being there is not Adam, but rather Lilith. Kaworu believes that this destroys his purpose in life and begs Shinji to kill him, which he does after a long moment of hesitation. Kaworu's death sets of the events in End of Evangelion.

In End of Evangelion, he appears as an illusion to Shinji, appearing opposite of Ayanami Rei in arguing if Shinji should accept or reject Human Instrumentality. He argues that Shinji should accept Instrumentality as the best thing for humanity.
