Intro. Wakanda (based on the Marvel Comics location of the same name) appears in media set in the Marvel Cinematic Universe (MCU). Inhabitants from this version of the country speak in the Xhosa language, as T'Challa's actor Chadwick Boseman developed using a "regional accent based on where Wakanda would be. He did great research on the very cultural aspects of the character. Even though it's a fictional culture, [he figured out] ways to tether it into real African culture." Additionally, it is located at the northern end of Lake Turkana, at a fictional point bordering Ethiopia, South Sudan, Uganda, and Kenya. In real life, this area is actually a disputed border region known as the Ilemi Triangle, claimed by each of these countries. This follows the location of the country in the comics according to Marvel Atlas #2.
