Leonardo

In the late 1980s, German publisher Egmont Ehapa launched Leonardo, a five-issue comic series that placed the Teenage Mutant Ninja Turtles' resident genius in the spotlight. This standalone adventure, running from 1989 to 1991, offers a focused, character-driven story distinct from the main TMNT titles, highlighting Leonardo’s leadership and discipline. Though short-lived, the series is a notable European take on the franchise, showcasing the global reach of the Turtles phenomenon.
