Something I've done a lot of for Wizard and ToyFare magazine were these mash-up comic strips where I'd take popular genre characters from comics, sci-fi, and draw them in the style of a classic newspaper comic strip. Most of the gags and strip ideas were generated by the editorial staff and I was just hired to illustrate them, but a few were ideas I pitched myself. They were pretty fun and emulating (or at least doing a passable likeness) of the original art styles was a real challenge.
(Peanuts / X-Men)
I think this is the first one I did.
Orlando Bloom County
(Lord of the Rings / Bloom County)
This one was my favorite.
this appeared in a fake Daily Planet newspaper
Phantom the Menace
(Star Wars prequels / Dennis the Menace)
The Doctor Doom Is In
(Doctor Doom / Peanuts)
I think this was for Inquest, I never actually saw it in print, but I have seen it used for people's internet avatars all over the web.
The Dark Side
(Star Wars / Far Side)
Fantastic Family Circus
(Fantastic Four / Family Circus)
This is one of the ideas I pitched myself that got greenlit.
(Garfield / He-Man)
Kraven and Hobbes
(Calvin and Hobbes / Spider-Man villain Kraven the Hunter)
(Nancy / Sin City)
I had pitched an idea for "Sin Ziggy" but this was way better.
Little Zemo in Slumberland
(Little Nemo / Baron Zemo, a Marvel comics villain)
Spy vs Spy vs Alien vs Predator
This was printed in color, but I think it looks more authentic in B&W. Mad Magazine even reprinted it, so now I can tell people I'm a published Mad cartoonist.
(Thundercats / Katzenjammer Kids)
(Prince Valiant / Valiant Comics)
Only people who read comics in the early 90's will get this one.
I just noticed I colored his gloves white in panel one, and then red in panel three. That's just awesome.
