Ok so I watch Steven Universe, Gravity Falls and Adventure Time. What other children's animated shows that have large manchild fanbases should I watch?

Or have a combination; your one stop cartoon for all your autistic needs
Yea this is about the only one you're missing that isn't MLP. Tho unlike those other three you mention in the OP, Star vs Forces of Evil is actually for children without much of its writing dedicated to the manchild demographic. So expect a pretty major shift in tone for SU, GF and AT, it actually IS a Saturday morning cartoon for young girls. As opposed to "alleged kids show that is actually mostly watched by a 20+ demographic."
I would say a total of 3 out of the, what, 20ish? eps have "lore." It's not like the OP's shows where the lore completely overtakes the show, but then again, its only had one season.
