Leonardo

A curious and intriguing entry in the Mirage catalog, this Leonardo made his first appearance in Teenage Mutant Ninja Turtles #27 in 1989, brought to life by creator Michael Dooney during the fertile Copper/Modern Age of comics. Sharing pages with the likes of Raphael, Donatello, Michelangelo, and Splinter across a span of roughly two decades, he moves through some genuinely eclectic company — turning up not only in Teenage Mutant Ninja Turtles but in the pages of Superman and Adventures of Superman, which makes for a fascinatingly unexpected comics footprint. With only ten catalog appearances, this is a character for the dedicated completist, the kind of quietly rare figure that rewards a collector who loves digging beneath the surface of a beloved franchise.
