Ditko was a regular contributor to Globe Communications' CRACKED briefly in the mid-1980s, usually doing just one or two page stories in a series called "Robot War" (which seems to be Spy vs. Spy, but with robots). He also did a few longer parody stories, such as this 5-page version of the cartoon Thundercats called, naturally enough, "Blundercats". The story, by Mike Carlin, is no great shakes, might make more sense if I was familiar with the characters at all, and does get a few points for featuring a Krazy Kat reference. Ditko does make the best of it, doing that great ink-wash style that he often did when working for black&white magazines, and his characters are nicely expressive and animated, and some really creative use of sound effects to direct the eye and add to the humour.
I haven't seen them, but a bit later Ditko also did several short stories for Globe's MONSTERS ATTACK title.
