Nigeria, officially the Federal Republic of Nigeria, is a country located in West Africa.
Upon arriving in Lagos, Scarlet Witch and Black Widow decided to go undercover at a local cafe while Falcon positioned himself on a rooftop overlooking the city. After noticing that a truck was quickly approaching the IFID, Falcon deployed the Redwing only to realize that the truck was a battering ram.
By then, however, the truck had driven through the entrance and Rumlow's mercenaries started firing at several security guards stationed outside. As poisonous gas flooded the complex, Rumlow quietly made his way to the third floor and found the bioweapon he was looking for.
Converging on the building, the Avengers took down several of the mercenaries while Falcon used the Redwing to find Rumlow before informing Captain America. After using her powers to lift Captain America onto the third floor, Scarlet Witch focused on venting the gas out into the open air while the others dealt with the remaining mercenaries.
Captain America searched for Rumlow only to discover that he had left the building. Black Widow intercepted and tried to electrocute Rumlow only to learn he could no longer feel any pain. He then threw a grenade at her, but she used a dead mercenary's corpse to shield herself from the blast. Rumlow escaped, but not before entrusting the bioweapon to one of his men.
While Falcon, Scarlet Witch, and Black Widow set out to find the other mercenaries and retrieve the bioweapon, Captain America confronted the former STRIKE commander, who blamed him for his injuries.
Meanwhile, Black Widow located the mercenaries tasked with maintaining the bioweapon and confronted them. When they threatened to kill everyone in the surrounding area unless she surrendered, she reluctantly complied. At the last minute, however, the Redwing subdued them and allowed Black Widow to secure the bioweapon.
Captain America 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 claimed that Bucky Barnes was pulling the strings before activating a suicide bomb attached to his vest, intent on taking Captain America with him.
Containing the explosion around Rumlow, Scarlet Witch attempted to move the blast away from innocent bystanders. However, she moved it too close to a nearby building and inadvertently destroyed it, killing twenty-six people, eleven of them being relief aid workers from the African nation of Wakanda.
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 Wakandan spy Nakia from her undercover assignment with missing Chibok girls held captive by terrorists.
T'Challa droped 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 wold 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.
