Post-Crisis, the concept of Earth-2 was done away with, meaning the original Huntress, Helena Wayne, was no more. Writers Joe Staton and Joey Cavalieri, who had previously worked on the Helena Wayne version of the character, were tasked with creating a new version. Helena was Now Helena Bertinelli, born into a mafia family which she witnessed being murdered at age 19, setting her out on a one woman war of the mob.
This is the original series that starts with the Huntress also known as Helena Bertinelli. From issue one it is just the Huntress becoming a hero and the struggles she is involved in and ends with a three issue arch with Batman and her becoming part of the Batman Family.
