Despite space-consuming use of black outlines in the (ultimately triumphant) underground ANSI art style, Tom Bradford somehow manages to cram in an incredible amount of detail in his Batman's physique, with different muscle groups isolated, utility belt and grapple hook gun clearly shown, the contours of a flowing cape indicated with appropriate use of shadow, etc. It's a pity he exhausted his allotment of detail, because the rest of the scene is drawn in pretty broad strokes, but it definitely tells the viewer where to focus their gaze!
The DoLittle gets points for ASCII art bats and reinterpreting the Batman logo with a Yen symbol at its heart, and for leaving the rest of the actual detail to the viewer's imagination.
OK, we're done with Marvel, but as far as niche cases go, there's still one very important avenue to explore: Mirage Studios' primary export, the Teenage Mutant Ninja Turtles. ANSI colours don't provide great matches for their identifying bandana-masks, but I'm going to call that one purple, making Stinky's terrapin above Donatello.
