In Captain America: Civil War, T'Challa takes the mantle of the Black Panther after his father is killed. As the Black Panther, he appears to have enhanced abilities.
In this interview with Collider, the Russos talk about T'Challa having superpowers and being enhanced during Civil War
JOE: It can absorb the energy, so it’s much harder to damage him as a character, and you can see that in the movie he can take a lot of punishment including bullets to the face. He is very well trained. He’s from one of the wealthiest countries on the planet, so there’s great infrastructure there; very technologically advanced country. So he’s been trained at the highest levels to fight, but he also has his own superpowers, which derive from the mythology of his nation. Those will be explored more in Black Panther, it’s clearly evident when he’s able to fight the Winter Soldier out of costume, and go toe-to-toe with him, that he is an enhanced individual.
In Black Panther, we see that in order to become the Black Panther,
one must imbibe juice from the heart-shaped flower and visit the spirit plane after being buried.
But before this,
T'Challa must have his Black Panther powers removed prior to the ritual combat challenge, which he does twice in the film.
This raises the question of how T'Challa could have possibly become the Black Panther abroad - or if he even really had.
