One of Our Favorite Heroes ... er, Thieves

Arsène Lupin (from the fantastic Cool French comics site)

From Wikipedia:

Arsène Lupin is the name of a fictional gentleman thief who appears in a book series of detective fiction/crime fiction novels written by French writer Maurice Leblanc, as well as a number of non-canonical sequels and numerous film, television, stage play and comic book adaptations.

A contemporary of Arthur Conan Doyle, Maurice Leblanc (1864-1941) was the creator of the character of gentleman thief Arsène Lupin who, in France, has enjoyed a popularity as long-lasting and considerable as Sherlock Holmes in the English-speaking world.

There are twenty volumes in the Arsène Lupin series written by Leblanc himself, plus five authorized sequels written by the notorious mystery writing team of Boileau-Narcejac, as well as various pastiches.

The character of Lupin was first introduced in a series of short stories serialized in the magazine Je Sais Tout, starting in No. 6, dated 15 July 1905.

Arsène Lupin is a literary descendant of Pierre Alexis Ponson du Terrail's Rocambole. Like him, he is clearly a force for good, while operating on the wrong side of the law. Those whom Lupin defeats, always with his characteristic gallic style and panache, are worse villains than he. Lupin is somewhat similar to A.J. Raffles and anticipates characters such as The Saint.

The character of Arsène Lupin might have been based by Leblanc on French anarchist Marius Jacob, whose trial made headlines in March 1905 ; but Leblanc had also read Octave Mirbeau's Les 21 jours d'un neurasthénique (1901), which features a gentleman thief named Arthur Lebeau, and seen Mirbeau's comedy Scrupules (1902), whose main character is a gentleman thief.

Lupin's lineage has also spawned a Japanese take in his grandson, Lupin the 3rd:

The gang from the Lupin the 3rd anime

Lupin III is a manga and anime media franchise created by Kazuhiko Kato under the pen name of Monkey Punch. The franchise follows the adventures of a gang of thieves led by Arsène Lupin III, the grandson of Arsène Lupin, the gentleman thief of Maurice Leblanc's series of novels. Lupin and his gang travel throughout the world to steal treasures and escape from the law.

Each project within the Lupin III universe has its own plot. The overall plot of the franchise centers on the international thief Arsène Lupin III. He is joined by Daisuke Jigen, Lupin's closest ally; Fujiko Mine, the femme fatale and Lupin's love interest who works against Lupin more often than with him; and Goemon Ishikawa XIII, a master swordsman and the descendant of Ishikawa Goemon, the legendary Japanese bandit. Lupin is often chased by Inspector Koichi Zenigata of the ICPO, the descendent of Zenigata Heiji. A rather cynical detective, Zenigata has made it his life's mission to chase Lupin across the globe in hopes of arresting him.
