Kakuzu

Kakuzu was a very greedy and stingy individual, setting his goals based on the greatest profit he could make, and was often unwilling to interfere with anything he couldn't gain from it. He also claimed to forget about opponents worthless once he'd dispatched them. He also noted that there was nothing more reliable than money. Consequently, he called himself "Akatsuki's Wallet." Judging by his good relationship with Zangei, Kakuzu brings him (or at least tries to) several shinobi corpses during a single mission.

Kakuzu is a fairly tall man with dark skin (the second tallest member of Akatsuki) and dark brown hair. Despite his advanced age (91), he still doesn't look old, more like a man in his prime, as he retains a fairly muscular build. His eye color is quite unusual: green irises with no visible pupils and red sclera.
