Milquetoast is the name of a cockroach in the comic strips Bloom County and Outland by Berkely Breathed. He was not a major character at first, but then again, neither was Bill the Cat. Along with Bill the Cat and Opus he travelled from Bloom County and became a major character in Outland. I believe he first appeared as a cockroach that whispered things into humans' ears to make them say and do goofy things.
