Daniel Kaluuya's character broke hearts when he ditched his best friend and former ally T'Challa to support Killmonger. Black Panther may not have been able to bring W'Kabi the man who killed his parents, but he absolutely showed his best friend that blood is thicker than water when he supported Killmonger against T'Challa. Looking for a couples costume? W'Kabi and Okoye are a fierce option — just know that Okoye will probably convince you to surrender all of your candy . . . just saying!
