Garona may not have been built as a living weapon, but being bred as a half-orc half-draenei assassin is about as close as you’re going to get in the Warcraft universe. In World of Warcraft, Garona has climbed the ranks of the rogue’s guild to become their leader, but she started out in much the same place as Gamora, a slave to the whims of her creator, forced to kill those she respected against her will. You know, the usual heartwarming stuff.
Garona’s version of Gamora would no doubt include much less almost hand-holding with the Star-Lord, and instead deal much more avenging herself on her father. And instead of seeking unspecified adventure in galaxy, I expect Garona to head straight for Azeroth the first chance she got, to make sure she can take care of business back home now that she has some strong allies at her side.
