Arpine Lusène is a fictional character of the Scrooge McDuck Universe created by Keno Don Rosa.

Nicknamed, Le Chevalier Noir (The Black Knight), he is a French gentleman, and a notorious thief with, naturally, a cheesy french accent which other characters have hard time understanding at times, and which often leads to clever word play. His home has been told to be his castle in Portofino on the French Riviere.

He is a very sticky fingered thief. On some occasions he is even seen stealing people's clothes while the victims are wearing them. His goal is to steal Scrooge McDuck's money, or make it disappear to make people think he stole it. His motive for this is to be remembered as the greatest thief ever to exist, not to make profit out of it for he's got plenty of money himself.

Usually on his appearances, Luséne wears an armor of a knight, almost completely covered in Gyro Gearloose's invention, an universal solvent which has the ability of absorbing all kinds of matter, excluding diamonds.

Lusène has appeared in a couple of stories, the first one The Black Knight in 1997.

He is based by spoonerism on Arsène Lupin, a fictional character from novels by Maurice Leblanc.
