Attack on Titan
Attack on Titan is basically a mecha anime in disguise, and you’ve probably already heard about how dark and violent the show is, something that easily makes it relatable to Evangelion.
Attack on Titan takes place on a dystopian planet, where humanity has been forced to the brink of extinction by horrific giant monsters called Titans (kinda sounds like the Angels in Evangelion, huh?). Now humanity lives within the enormous walls of one final bastion, hiding away from the Titan menace.
Apart from the obvious story and thematic similarities, Attack on Titan is a deconstruction of the shonen genre, like how Evangelion is a deconstruction of the mecha genre. Attack on Titan’s story often delves into the world of ethics and existentialism, totally flipping what you might expect from the usual shonen anime.
Eren in Attack on Titan is also an unlikely hero, hellbent on revenge to a ludicrous degree, and surprisingly violent and ruthless at times.
Surely you’ve already heard plenty about Attack on Titan, right? It’s only been the biggest anime of the last decade, so go watch it.
