Are there any non-MCU marvel/shows cartoons that are worth watching for adults?

I'm counting Daredevil and Runaways and stuff debated as whether it's part of the MCU or not as part of the MCU for the sake of this question. I tried watching the x-men cartoon series but it really feels like it was made for children and only for children. I know there was an Incredible Hulk show with Lou Ferringo in the 80s, but not sure what other live action marvel TV there has been, so I suppose I mostly mean just cartoons.

Also I'm an adult who loves Steven Universe and some anime that was made with children in mind first, so if there is anything like that I'll give it a shot.

edit: I'm looking for marvel shows specifically
