Black Panther

T'Challa a.k.a. the Black Panther was the Head of state of the African nation of Wakanda, the most technologically advanced country on Earth. In this role, he was the King/Chieftain, religious leader, and commander-in-chief all rolled into one. He is also considered among the top intellects in the world. Using Wakanda's advanced Vibranium technology and his own abilities and fortune, he pledged his life to the service of all humankind. He would go on to become a prominent member of the Avengers, and eventually become leader of the team. While recent revelations about his time as Wakanda's ruler would strain his relationship with both his subjects and his fellow heroes, ultimately leading to his exile from the country, he remains an Avenger and a stalwart protector of his people.
