Leonard the Duck

Few characters make their mark in just three appearances, but Leonard the Duck arrived in 1996 with a debut issue that collectors already flag as key — a crossover event uniting the worlds of Image's Savage Dragon and the legendary Destroyer Duck. Born at the tail end of the Copper Age and stepping into the Modern era, this Image Comics oddity shares pages with some genuinely wild company: the Teenage Mutant Ninja Turtles' own Leonardo, Michelangelo, Raphael, and Donatello, plus Rhonda Martini, making for one of the more eclectic rosters you'll find in a single title. Co-created by the inimitable Steve Gerber — the visionary mind behind Howard the Duck — Leonard the Duck is a rare, quirky footnote with serious pedigree, the kind of deep-cut discovery that reminds you why digging through back-issue bins is always worth it.
