Nigeria, officially the Federal Republic of Nigeria, is a country located in West Africa.
Planning to steal a biological weapon from the Institute for Infectious Diseases, Crossbones and his mercenaries traveled to Lagos, however, he was spotted by the Avengers. Captain America, Falcon, Black Widow, and Scarlet Witch arrived a Lagos and went positioned themselves, observing the scene. After noticing an incoming garbage truck was quickly approaching the IFID, Wilson deployed the Redwing only to realize the truck was a battering ram.
By then, however, the truck had driven through the entrance and Rumlow's mercenaries had opened fire on security guards. As poisonous gas slowly flooded the building, Rumlow quietly made his way to the third floor and found the bioweapon he was looking for. The Avengers then converged on the building and proceeded to take out several of the mercenaries. Falcon used the Redwing to find and confirm Rumlow's location before informing Rogers.
Using her powers to lift Rogers onto the third floor, Maximoff then focused on venting the gas out into the open air while the others proceeded to deal with the remaining mercenaries. Rogers searched for Rumlow only to learn that he had already left. Romanoff managed to intercept Rumlow and tried to electrocute him only to learn he can no longer feel pain. He then threw a grenade at her, but she used a dead mercenary's body to shield herself from the blast. Rumlow escaped, but not before entrusting the bioweapon to one of his men.
Wilson, Maximoff, and Romanoff set out to retrieve the bioweapon, and Romanoff managed to locate it and confronted the mercenaries tasked with maintaining it. When they threatened to kill everyone in the surrounding area unless she surrendered, she reluctantly complied. The Redwing suddenly appeared and subdued them while Black Widow secured the bioweapon.
Meanwhile, Rogers managed to subdue Rumlow and began pressing him for information as to the identity of the person who ordered him to obtain the bioweapon. Rumlow then mentioned Bucky Barnes and how Barnes knew of Rogers before HYDRA wiped his memory, taking advantage of Rogers' stunned reaction to activate a suicide bomb attached to his vest, intent on taking Rogers with him. Maximoff managed to contain the explosion around Rumlow and tried to move the blast away from innocent bystanders. However, she moved it too close to a nearby building and inadvertently destroyed it, killing numerous civilians and 11 relief aid workers from Wakanda.
Steel Serpent's Sales
Returning home to Wakanda a week after his father's death, T'Challa and Okoye first flew to the Sambisa Forest in Nigeria, hoping to extract Nakia from her undercover assignment with missing Chibok girls held captive by terrorists. T'Challa dropped from the jet, throwing EMP Beads, which attached themselves to the terrorists' cars and disabled them. T'Challa then hid in a tree as the terrorists got out of their vehicles. Leaping from his hiding spot, T'Challa engaged the terrorists, the Panther Habit absorbing all their fire.
He took them out with ease, and Nakia stepped out to help in the fight. She prevented T'Challa from killing one of the men, who had been forced to join the terrorists against his will. T'Challa lost focus at seeing his ex-girlfriend again, and a terrorist took advantage of the moment, threatening to shoot one of the girls if T'Challa moved. Okoye, however, took out the final man, having expected T'Challa to freeze and dropped down herself to help.
Nakia was frustrated at T'Challa for ruining her assignment, but he informed her of his father's death and the fact that he would be crowned tomorrow and wanted her to be there. Okoye, meanwhile, freed the Chibok girls and sent them off safely, warning them not to speak of the events that just unfolded.
