She may be King T'Challa's younger sister, but even without her royal family, Shuri (played by Letitia Wright) is a powerhouse alone. Leading the Wakanda Design Group with her innovative technology ideas, the 16-year-old genius engineer is so much more than a brainiac badass. If you go as Shuri this Halloween, just make sure to keep your vibranium gauntlets handy and, of course, tease T'Challa with a solid "What are thooooose?!" joke.
