What is his power? Is it the costume? Is it that he’s been training like Jason Bourne?
JOE RUSSO: It’s a combination of everything. Certainly the costume gives him a level of protection and invulnerability because of the material that it’s made of.
ANTHONY RUSSO: Which is vibranium, for non-fans, and it’s the same material that Cap’s shield is made of.
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.
