The Wakandan general apparently went through several costume designs, with one piece of concept art showing her sporting an electrified version of her signature spear.
Black Panther is almost certainly guaranteed a sequel, and if Okoye survives the events of Avengers: Infinity War, perhaps these concept art designs could come into play.
With Ryan Coogler’s Black Panther movie clawing away at the box office, concert art has emerged revealing alternate costume and armor designs for Danai Gurira’s character Okoye.
Given how important Okoye was during the Busan chase sequence with Klaue, it is easy to imagine her using the concept art spear in battle.
