Al Williamson's Savage World

Savage World is an interesting one. At first, it seems to be 'just' another wonderful Al Williamson piece, with the added attraction that it stars Larry 'Buster' Crabbe. But there's a lot more to it than that, including the fact that it covers nearly the whole of comic history, having first appeared in the '50's, then being seemingly endlessly reprinted in the '60's, '70's, '80's AND '90's. Not bad going for a simple 8 pager. Plus, this actually isn't Williamson flying solo.
Here, from Kitchen Sink's Death Rattle, is Al in conversation with Dave Schreiner, to tell the whole story:

 And here's the strip:

And, as we're all completists here, how about a gander at the aforementioned rewrite by Bruce Jones, from Alien Worlds. You got yerself some brass ones, don't'cha Bruce, rewriting Wally Wood & Al Williamson?

Cobalt 60

Vaughn Bode: " I set up the Cobalt 60 strip and found myself uneasy, restless and wandering toward fluttering creative excitements. It's flowing out of me again like water...I can really identify with the dusty future of Earth... where I will be part of the quiet hissing afternoon dust..."

Cobalt 60 is one of the darkest, if not THE darkest, projects in Vaughn Bode's work. A post-apocalypse punch in the face, it's grim, ultra-violent and despairing, and comes with a killer ending that, like Bode's earlier The Man, shows The Cartoon Gooroo's mastery at delinating big themes with a minimum of words. He was an artist who wrote, rather than a writer who drew, and that's never clearer than here.
Vaughn originally created Cobalt 60 in 1959, but the death dealing mutant didn't see print until 1968, in the above issue of Wally Wood's Witzend, in the process winning him the Hugo award for Best Fanzine Artist of that year.
He created a whole world for Cobalt to move around in, along with a full cast of characters, but ultimately found the series too depressing to continue with and abandoned the idea. It was also a major 'influence' on Ralph Bakshi's Wizards, a film Bode was reportedly none too happy about.
As nice an idea as Bode in animation is, his work kind of doesn't need it, being the closest thing to 'static' animation there is, and Cobalt 60, in particular, is a strip that could only be in presented in black & white anyway. Here it is:

Vaughn did try one more time with Cobalt 60, with this unfinished piece posthumously published in Junkwaffel #4. This one is even darker and more uncompromising than it's predecessor, and you do get the feeling that even Vaughn felt he'd written himself into a corner.
Which is presumably why, when son Mark Bode took up the character in 1984 for a new series in Epic Illustrated, he went in a completely different direction. We'll get to that series, of course, but here's the original.

Animan

From the first couple of issues of Witzend, here's all there is of Wally Wood's Animan, a character Woody originally created while still a child.

It starts off in familiar territory, then becomes increasingly violent and darkly sexual ( for the time at least ). In fact, I think I read somewhere that the reason the strip was never finished was that Woody couldn't think of anything else to do with it, and that any third installment would just consist of Animan and female lead Cathy having sex for page after page. 

It's Wally sort of between styles, being neither as hyper detailed as his EC work, nor as minimalist as T.H.U.N.D.E.R Agents, but what it is, of course, is completely wonderful.
