Kaworu’s a fairly enigmatic character both in-universe and Eva’s fandom circles. He does, however have a lot of subtleties which can be easily overlooked by any viewer. This page is a gigantic guide to his character from the anime, the Rebuilds, as well as the games, official and unofficial manga. It also delves into his relationships with other characters (Shinji, Rei, and Asuka). As such it addresses common as well as subtle points of his character and common misconceptions. The pages that aren’t boldfaced are personal analyses I’ve made over the years. Others, marked in bold, belong to others. I’ve also made warnings to the respective links as well.
Although I canonically ship the Chocobros as they are (close brothers with that kind of relationship you can
interpret
as you like), I definitely don’t dislike interactions of this sort in fanarts. Since we don’t really get similar heartwarming scenes in the game I decided to make my own fix. See it as you please.
