Lupin III is the world's most wanted gentleman thief. Often in his adventures, he takes it upon himself and his gang to foil other criminals engaged in more serious crimes. He sometimes appears incompetent, but mostly as a charade to catch his opponents off guard. While he has been arrested and thrown in jail on a number of occasions, he has always managed to break out.
He also has a fondness for fancy gadgets from time to time, such as in The Castle of Cagliostro where his belt features many small gadgets. His infatuation with women, and Fujiko Mine in particular, is perhaps his biggest weakness, as it often lands him in undesirable situations. He continues his grandfather's legacy of thievery.
