T'Challa is the King of Wakanda and first son of T'Chaka and Ramonda. As the Wakandan monarch, he became the holder of the Black Panther mantle. Following the death of his father in the bombing attack orchestrated by Helmut Zemo, T'Challa had set out to kill the Winter Soldier, who was widely believed to be responsible for the attack. During his attempt to find the Winter Soldier, Black Panther had joined a Civil War between the Avengers, where he sided with Iron Man. However, Black Panther eventually learned that Zemo was really the one who had been responsible for his father's demise, as he captured Zemo, handing him over to Everett Ross, while he also vowed never to allow desires of vengeance to consume him again.

Upon returning into Wakanda, T'Challa was officially crowned King, before he attempted to track down Ulysses Klaue, who had resurfaced after several years. However, T'Challa failed to capture Klaue and instead was forced to bring Everett Ross to the city to save his life. T'Challa's leadership was challenged when Erik Killmonger came into Wakanda, having killed Klaue and challenged T'Challa for their throne, as Killmonger bested T'Challa in a duel and took the crown. However, T'Challa had survived the duel and, with the help of M'Baku and his family, returned to Wakanda where he defeated Killmonger. Following the conflict, T'Challa returned to the United Nations as he had shared Wakanda's secret wealth with the rest of the world.

Black Panther was then called upon by the Avengers, as they had uncovered Thanos plan to claim all six Infinity Stones and wipe out half of all life in the universe. T'Challa agreed to allow the Avengers to keep Vision in the city, where Shuri could remove the Mind Stone. However, Wakanda was then invaded by Thanos' forces, as Black Panther had led his army against Thanos and the Black Order, only for them to be overpowered as Thanos completed his goal and then wiped out half of life, killing Black Panther as a result. However, Black Panther was resurrected five years later by Hulk, as he then joined the Avengers in a final battle against Thanos, finally defeating the Mad Titan, although Tony Stark sacrificed his life for victory.
