The Maxx was pretty out of it. To be fair, I watched the animated version, but I can only assume the comic was more wierd

Image comics in general has tons of great stuff that isn't superhero genre and Boom is really getting some good stuff lately. I'm a huge Tynion fan, so Something is Killing the Children, Department of Truth and Nice House on the Lake really stood out the last few years.

I like your list & would recommend

Black Science.
Monstress

I also enjoyed

Elephantmen.
Low.
East of West. Hickman in general is good.

Anything by Mike Carey - if you like Sandman you will like Lucifer, and he also did Darkness Visible, Highest House and some mainstream stuff.

Trashman

70s, hobo, superhero, sex fiend IIRC

Picked up the compilation at a 2nd hand store. Adult themes and graphic depictions.

Congrats on The Invisibles and The Incal. I still remember when Animal Man #1 was released in the newsagents.. I may have a copy around somewhere.

For more Morrison and Moore, trawl the 2000AD back progs/graphic novels.

Future Shocks short strips by Moore. I think he did DR. and Quinch also. A-grade

Other stories of merit from 80s-90s 2000AD:

Zenith

PJ Maybe

Button Man

Finn

The one hand and six fingers might fit your interest quite well. Anything Ram V will fit btw, his stories are all thoughprovacotive in one way or another.

I may come back to this and update with the surreal shit ive read, was how I got into comics a few years ago, there was some weird sht, it was great. Having a hard time remembering them right now

all the dial h for hero stuff, like dial h h.e.r.o lumires animal man is great too iredeemable and incorruptible planetary archer and armstrong 2012 reboot of valiant, the dahrk stuff too multiversity loki run gets real surreal, look up reading guides

I have so many better ones I have listed somewhere. Will update this comment.
