I wouldn't get my hopes up... I have pretty strong indications that you'll be reborn instead. The upside is, more chances for "Gluttony, jealousy, anger, lust.." ^_^

I loved Darkwing Duck as a kid. That show really resonated with me.
Edit: also Count Duckula and Danger Mouse.

I remember some episodes of this strange anime were shown on TV when I was a kid. Weird stuff...

Karasu Tengu Kabuto

Barefoot Gen

I'm surprised that no one has mentioned Courage the Cowardly Dog.

Speed Racer. First anime I ever watched; it's so old, in fact, that it predates the word "anime" itself.

And trippy? Even the bowlderized, kid-friendly version that aired on Saturday mornings had cars driving off cliffs and explosions galore. Plus, the episodes were shown out of order (story arcs weren't yet a thing in 1970s children's shows) so it was often hard to tell what was really going on. But for maximum trippiness, I recommend you watch the live-action 2008 movie.

Likewise with Battle of the Planets, which was the US kid-friendly version of Gatchaman. I have the anime on DVD, and was actually a little disappointed that the cutscenes featuring 7-Zark-7 weren't included. (They were added to the US version to extend the show's running time, since many of the battle scenes had to be cut down due to excessive violence).

Big fan as well of Heavy Metal, which mannefriedrich already mentioned. Saw that movie dozens of times during midnight showings in theaters, and bought it as soon as it came out on DVD.

And if we're going for out-there cartoon shows, no list would be complete without Aqua Teen Hunger Force, Venture Bros, and Invader Zim.

You would absolutely love Chick Tracts, then. It sounds like the American version of what you read, and they are so over-the-top that they're actually funny... especially since they were meant to be completely serious.

I wouldn't be surprised they were those same, as the Wikipedia article mentions they were translated to quite many languages, possibly also Finnish.

I have no idea if the guy was a Jehovah's Witness, but that is the first thing that occurs to me when I think of Christian types here who stand on the streets handing our something to bypassers.

Also I am pretty sure I've mentioned this "Christian cartoon" episode before here in GOG forums, I don't recall what was discussed back then...

One of them was made into a movie:

That's a great list thanks, there's a few titles in there that I can see myself watching. But it's Thundarr that's the closest aesthetically to what I remember:

The combination of black, redish and blue-ish looks right, but I don't think it was as cheesy or as old as Thundarr. The theme feels off. I vaguely remember it being quite melodramatic.

Can't believe those shows are nearly 20 years old! Cow and Chicken's first episode was 21 years ago :P
But no, I'm thinking my mystery show was early 90s. I wonder if I can download old tv guides somewhere and just go through all the damn shows

The New Adventures of Flash Gordon, perhaps?

Someone who sports Thirty/Thirty as the forum avatar probably would be familiar with Galaxy Rangers? Episodes involving or centered around the Slaverlords or the Scarecrow character were grade-A nightmare material back then.

Another unusual animated series would be Pandamonium, but besides its trippy premise it's probably leaning more towards the light-hearted end of the spectrum.

As whacked out as Courage is, it at least follows an internal logic and does often have overarching stories.

Have to second this. I think I didn't understand English back then. To this day I believe that made The Maxx even more enjoyable.

I'm reasonably sure the creators of Ulysses 31 were permastoned.
