What is the Evangelion of Yea Forums?
Star vs the Forces of Evil.

I still haven't managed to get my hands on it. American Pop is my favorite film.
Watchmen
Rick and morty.
Fans of both claim it's very intelligent when in reality both were random shit randomly written just because.
And people lap it up like a dog
sahm-uuuuu-ry jack
Makes sense, they're both pure shit and both protagonists are whiny effeminate faggots
We have had this thread a couple of times before, and the ultimate answer is that there isn't one. Evangelion was a weird combination of factors and runaway success that impacted the industry that hasn't even happened again in the context of anime.
Western cartoons don't have the foundation of being taken seriously and the merchandising base aimed at adults to create the environment needed for something like Evangelion to take root in the first place. Evangelion was a deeply personal story that hit the right note at just the right moment in the culture it came from, and made a splash that extended far beyond the boundaries of its expected audience and its success had a huge wave of secondary effects on how the anime industry targeted and promoted its shows.
There are western comics or cartoon properties that hit one or two check boxes for what Evangelion did, but none of them managed to get bingo. Watchmen had a noteworthy impact on the comics industry, but it had nowhere near the cultural splash that Eva did and it lacks the raw author blood-on-the-page mess that made Eva what it was in the last third of the show. Steven Universe might make an occasional reference to scenes from Eva, but they are just that: references. The greater context and impact is lost.
The west doesn't have an Evangelion, and as long as the west considers cartoons to inherently be for children, we probably never will.
Bojack Horseman then
Definitely either Watchman or Homestuck.
