Leonardo Ortolani, Italian author and illustrator, created Rat-Man

Leonardo Ortolani, better known as Leo, is an Italian comics author, creator of the comic book series Rat-Man.

Rat-Man is an Italian comic book about an inept superhero of the same name, created by Leonardo Ortolani in 1989. Although it was initially meant to be a satire of other superheroes, most prominently Batman, it has since evolved into an independent comic sporting a complex, evolving continuity. The comic is well known for its nonsense humor à-la Monty Python, its engaging storytelling and its frequent breaking of the fourth wall. Ortolani often pays both direct and indirect tribute to other comic authors and he frequently makes his characters use pop-culture references, either generic or specific to the native Italian context and background. The comic was published by Panini Comics as new installments under the name of Rat-Man Collection and is currently being published as reprints of older stories in Rat-Man Gigante.
