Last October, Marvel officially unveiled their Phase Three slate, revealing that Chadwick Boseman will play Black Panther, who will be introduced in Captain America: Civil War before his own stand alone movie. We got our first look at the Black Panther costume at that massive press event, but we haven't seen much more of this mysterious character since then. Today, Entertainment Weekly has a new photo of Black Panther, along with new details about this iconic character from the Captain America: Civil War cast.

Back in August, new promo art debuted for Captain America: Civil War, which revealed that Black Panther is on Iron Man's side, along with War Machine (Don Cheadle), Black Widow (Scarlett Johansson) and Vision (Paul Bettany). Team Cap includes Hawkeye (Jeremy Renner), The Winter Soldier (Sebastian Stan), The Falcon (Anthony Mackie), Sharon Carter/Agent 13 (Emily VanCamp) and Ant-Man (Paul Rudd). The promo art didn't reveal which side Scarlet Witch (Elizabeth Olsen) and Spider-Man (Tom Holland) will be fighting for, but, according to executive producer Nate Moore, it seems that T'challa hasn't fully made up his mind about which side he's on.

"He's someone who hasn't necessarily made up his mind about either side and whose agenda isn't exactly what Cap's agenda or what Tony's agenda is. And I think that brings him into conflict weirdly with both characters at different times in the film. He is the prince of an African nation that has so far stayed very much sort of in the shadows. And eventually the film will draw him and his father out of the shadows."

In the Marvel Comics, Black Panther hails from Wakanda, which is where vibranium comes from, the same metal used to create Captain America's shield. This summer's Avengers: Age of Ultron also featured a key character with ties to Wakanda, Andy Serkis' Ulysses Klaue, although it isn't known if he will surface in Captain America: Civil War yet. While the first trailer for Captain America: Civil War gave us a brief look at Black Panther in action, very little is known about how he ties into the story. Here's what Chadwick Boseman had to say about T'challa's presence in Captain America: Civil War.

"He's definitely not the life of the party in this instance. I think this is something true of the comic book character and the movie. You never quite know where he stands. There's always a bit of concealing and mystery. So I think mysterious is more his boat. Not to say there's not charm and he can't be a ladies' man and all that. It's more like if there is humor, it's more like James Bond. There definitely is a sort of tradition that he's torn between, in terms of how things were done in the past and how things need to happen now in this new world. I think there's perhaps a bit of a maverick there, and then there's also a need to live up to traditions and his father's legacy. And not even his father's legacy, but the entire nation of Wakanda. I think those are the things you will see."

Back in June, producer and Marvel Studios president Kevin Feige teased that T'challa is beginning to "take over" the Black Panther mantle from his father T'chaka. T'challa's father has been rumored to either die or pass on the throne to his son in Captain America: Civil War. In his interview with EW, Kevin Feige teases that T'challa has a "full arc" in Captain America: Civil War, not just a cameo.

"We kept talking about 'Somebody like Black Panther...' After the third or fourth time that came up in a development meeting, someone said, 'Can't we just do the Black Panther?' And we all looked at each other and said, 'Yeah, I guess we could.' We introduce him here, give him an arc, and make him a full character. We don't just give him a cameo, to wave. He has his own conflict and his own people that he's looking out for."

Directors Anthony Russo and Joe Russo also revealed that Black Panther's suit is actually made from vibranium, which could mean that his suit is virtually indestructible, much like Captain America's shield. Take a look at this new Black Panther photo from Captain America: Civil War, and stay tuned for more on this highly-anticipated superhero adventure, in theaters May 6, 2016.
