The Neon Genesis Evangelion manga has indeed finished. It reached its conclusion after a series of chapters and story arcs that wrapped up the plotlines.
Sure! Neon Genesis Evangelion has a manga version. It presents the story and characters in a different format from the anime, but still retains the core elements that made the series popular.
No way. Canonical content in Neon Genesis Evangelion is what was produced by the official studio and creators. Fanfictions, no matter how interesting or popular, are not part of the official lore. 'Lemon' fanfictions, which usually deal with more adult - like or unorthodox relationships between the characters, are completely fan - created and not recognized as official in any way. They are a form of fan creativity, but they have no bearing on the official story of the Evangelion series.
One popular theme is alternate universes. Fans like to explore what would happen if certain events in the original series were changed. For example, what if Shinji made different choices during battles or in his relationships. Another theme is character development beyond what was shown in the anime. Writers might focus on how characters like Rei could grow and change in different situations. And of course, there are fanfics that explore the relationships between the characters in more depth, such as the complex relationship between Shinji and Asuka, which can be a rich source of inspiration for fanfic writers.
An 'alternate universe neon genesis evangelion fanfic' often reimagines the Neon Genesis Evangelion story in a different setting or with altered plot elements. It could be a world where the Angels have different powers, or the characters have different relationships. Writers might explore what would happen if Shinji was more confident from the start, for example.
