One of the odder DC characters, Manhunter (not to be
confused with either the Martian Manhunter, nor the Manhunters
from OA) has been dead or a clone in the comics since
the mid 1970s. Based on a Simon & Kirby character
from the 1940s, the Paul Kirk Manhunter hasn't really
been used outside of the afore-mentioned 1970s backup
feature in Detective Comics.
I'm guessing Kenner just liked his look. It looked like
his throwing stars were removable, and he had a gun. Whee!

convoluted history here.
