All right, let's get really obscure. Kitten McGee was one of the main characters of Wildcat, a very short-lived British comic from 1988 that attempted to do something different with British comics' traditional anthology format - All the stories took place in the same setting, the titular giant spaceship carrying the last humans from a destroyed Earth in search of a new home.
Kitten starred in her own self-titled strip - A fierce former leader of a worldwide rebellion against men, leading her own all-female gang of fighters. She was also secretly centuries old, and sustained her youth Nick Fury style via ingestion of something called Infinity Dust (the comic never lasted long enough to actually explore this plot point in any way).
If nothing else, she's a striking character design, courtesy of Scottish artist Ian Kennedy.
