Among the many villains in the narutoverse, Kakuzu is one of those that I both admired and feared, mostly for the reason that his strength and power depends on the hearts of his enemies that he was able to collect. That's both a cool and terrifying power to have, which his behavior of killing his partners and not being able to cooperate with anyone doesn't really help with. Not to mention, his eyes are also intimidating alongside his excellent defense of Kakashi's Lightning Cutter.
