The Dora Milaje are the personal bodyguards of T'Challa and security to the royal family of Wakanda, acting as the country's version of the U.S.A.'s Secret Service. They are an elite squad of women who protect T'Challa and Wakanda with electric bow-staffs and advance body armor. They are skilled in many different martial arts, and they are skilled in espionage and strategy.
The Dora Milaje, primarily Okoye, appear throughout the film. They stand as T'Challa's representative warriors during T'Challa's right of passage against M'Baku's forces. During
the arrival of Erik Killmonger, T'Challa is presumably killed and Killmonger begins his takeover of Wakanda; the Dora Milaje reluctantly aligned themselves to their new king out of duty. But when T'Challa turns up alive, the Dora Milaje turn against Killmonger and return to T'Challa's side.
During the battle, Okoye and three other Dora Milaje fight valiantly against Killmonger (who was equipped with his own Jaguar Habit suit) but lose one of their members to the tyrant. The battle briefly turns to their favor with the assistance of Nakia and Shuri until Killmonger comes close to harming the latter. T'Challa intervenes and engages in a personal fight against Killmonger, allowing the Dora Milaje to focus their efforts on the rest of the battle. When the battle is won, the Dora Milaje resume their roles as Wakanda's royal protectors under the vision of T'Challa.
The Dora Milaje appeared in the episode "Rage of the Panther". They hid in the palace court out of site of the Avengers and ambush them. They fought mercilessly without relent of the tough team. Hawkeye even to the point of trying to hook up with one of the ladies, Aneka. Aneka was one of the three Dora Milaje to accompany the Avengers to take on Ulysses Klaw at his Himalayan base.
