<Li> Don Cheadle as James "Rhodey" Rhodes / War Machine: A close personal friend of Tony Stark's and an Avenger allied with Stark; an officer in the U.S. Air Force who operates the War Machine armor . Cheadle called Rhodes' appearance in the film a "bit more intense and pivotal" compared to his previous appearances . </Li> <Li> Jeremy Renner as Clint Barton / Hawkeye: A master archer allied with Rogers; a retired Avenger and S.H.I.E.L.D. agent . On Barton's reasons for joining Rogers' side, Renner said, "Cap was the first guy who called . Let's just get the job done so I can get home to the family," along with feeling an obligation to side with Scarlet Witch, since her brother, Pietro Maximoff / Quicksilver, sacrificed himself to save Barton in Avengers: Age of Ultron . On how he and Barton fit into the Marvel Cinematic Universe, Renner said, "I'm happy to be the ensemble . I'm not scratching or clawing to do a solo movie by any means...I think (Barton's) a utility guy that can bounce around into other people's universes a little bit". </Li> <Li> Chadwick Boseman as T'Challa / Black Panther: The prince of the African nation of Wakanda allied with Stark, who gains enhanced strength by ingesting the Heart - Shaped Herb . Producer Kevin Feige explained that the character was included "because we needed a third party . We needed fresh eyes who wasn't embedded with the Avengers and who has a very different point of view than either Tony or Steve ." T'Challa is in the "beginning phases of taking on" the Black Panther mantle, and appears in more than a cameo, with a full arc and character journey with "his own conflict and his own people that he's looking out for ." Boseman did not audition for the role, instead having a "discussion about what (Marvel) wanted to do and how I saw it and what I wanted to do ." T'Challa is torn between needing to live up to traditions and the legacy of his father and Wakanda, and how things need to happen in the present . Boseman developed the Wakandan accent himself, and used it during the entire production "whether he was on camera or not", while the Wakandan language was based on the Xhosa language, which Boseman was taught by John Kani (who plays T'Challa's father T'Chaka). The Black Panther costume is a combination of a practical costume and visual effects, featuring a vibranium mesh weave similar to chainmail . Costume designer Judianna Makovsky called the Black Panther costume "difficult" since "you needed sort of a feline body, but it's hard and practical at the same time . You needed a feeling of some sort of ethnicity in there, but of a world (Wakanda) we weren't really creating yet, so you didn't want to go too far and say too much about that world ." Additionally, Makovsky felt creating T'Challa's royal look was "a bit of a challenge", avoiding African robes after learning actual African royalty are generally "educated in the West (and) get dressed in Savile Row ." Boseman has a five picture deal with Marvel . </Li> <Li> Paul Bettany as Vision: An android and Avenger allied with Stark; created using the artificial intelligence J.A.R.V.I.S. and the Mind Stone . Because the Vision was only created in the previous film, Age of Ultron, Bettany said, "you see my character get born...He must be both omnipotent and yet totally naive at the same time . And experiencing the world in real time and his place in it . Is he going to be a force of good or a force of evil?" Bettany also said he was interested in exploring "what it means to be human and what love is" with the character, as "The only way one can guarantee one's loyalty is love ." This is exhibited in the connection Vision begins to form with Wanda Maximoff, with Bettany commenting, "They both have these new burgeoning powers that they don't understand...I think he's worried that they're both dangerous . So he feels this real connection with her ." As the Vision has the ability to create a projected disguise, he chooses to dress similarly to Howard Stark's attache, Edwin Jarvis . </Li>
