While Black Panther does an excellent job of explaining what the virtually indestructible and rare metal is and where it came from, vibranium has already appeared in several Marvel movies, Notably Avengers: Age of Ultron, where the evil android solicited some vibranium stolen from Wakanda…which ended up becoming the body of the synthetic Avenger, the Vision. In the comics, though, there’s one small difference. Captain America’s shield is made from an alloy of vibranium and adamantium. That makes the the shield so tough that not even Wolverine’s claws can cut through it. And it’s all because of the secret metal from Wakanda. So when T’Challa says “Get this man a shield” in that awesome trailer for Avengers: Infinity War, he knows exactly what he’s talking about. Because without Wakanda and the world of Black Panther, Captain America never would have had his shield in the first place!
