Lupin the 3rd's answer to Jet Black; he is the sharpshooter of the group and he kind of bosses everyone else around.
Actually that is inaccirate. Lupin the third came out in the late 50's early 60's waaay before Cowboy bebop. He is the sharp shooter with the lowered fedora.
Watch Jigen shoot down a helicopter in the opening scene.
"Alla Jigen" (from Italian, translation "Jigen style"):
to smoke a crumpled cigarette;
having a crumpled cigarette hanging from the corner of one's mouth;
Lupin the 3rd and his friend Jigen first saw the light in 1967.
What? Jigen bosses everyone else around?? Where? When?
Jigen is the best anime character ever!
A friend who's extremely trusty.
