Erik Killmonger's Campaign was a series of battles between Erik Killmonger's faction, whose goals were to overthrow the governments of the world and replace them with a Wakandan Empire, and those still loyal to T'Challa, who wanted to avoid war with the rest of the world.
- "I observed for as long as I could. Their leaders have been assassinated. Communities flooded with drugs and weapons. They are overly policed and incarcerated. All over the planet our people suffer because they don't have the tools to fight back. With Vibranium weapons they can overthrow every country and Wakanda can rule them all the right way."
- ―N'Jobu to T'Chaka
Klaue successfully stole a large amount of vibranium and detonated a bomb at the border, killing several members of the Border Tribe. N'Jobu took his share of the vibranium and began planning raids of select targets. However, before any of these raids could be pulled off, N'Jobu received a visit from his brother, T'Chaka and the Dora Milaje. After exchanging pleasantries and dismissing the Dora Milaje T'Chaka revealed the attack and his suspicions that a traitor was responsible for letting Klaue in Wakanda. Suspecting that T'Chaka meant him, N'Jobu asked him what he was doing in Oakland. T'Chaka confirmed that he knew N'Jobu was the traitor, revealing that James is actually Zuri, a War Dog spy. T'Chaka ordered N'Jobu to return to Wakanda to answer for his crimes nut N'Jobu pulled a gun on Zuri, forcing T'Chaka to kill him in order to save Zuri. Realizing that he had just killed his own brother, T'Chaka ordered Zuri to never speak of what had just happened. And in order for their lie to work, they left behind N'Jobu's son and told everyone that N'Jobu had simply disappeared.
Death of T'ChakaUltron Offensive T'Chaka slowly started to remove Wakanda from isolation. He sent a group of relief workers to Lagos who unfortunately died as a result of a battle between the Avengers and Crossbones. T'Chaka called for immediate oversight of the Avengers and became a strong advocate of the Sokovia Accords. He attended the signing of the Accords in the Vienna International Centre along with his son, T'Challa. During a speech, T'Chaka was giving at the signing a bomb detonated and killed T'Chaka. T'Challa eventually apprehended Helmut Zemo, the man responsible for the bombing and returned home to mourn his father.
A week after T'Chaka's death, Ulysses Klaue resurfaced. This time he was selling an artifact that contained vibranium on the black market. Locating him in Busan T'Challa gathered a group consisting of Okoye and Nakia and headed to South Korea, successfully capturing Klaue with the help of CIA agent Everett Ross. Before they could bring Klaue back to Wakanda, however, a grown-up N'Jadaka arrives liberates Klaue, and injures Everett. Though not before T'Challa sees his ring. T'Challa decides to take Everett to Wakanda for treatment while contemplating what he saw.
- "You... you want to go to Wakanda? They're savages! This is what they do to people like us."
"I don't worry about no brand. Check these out. Each one is for a kill."
"You can scar yourself as much as you like. To them, you'll just be an outsider. You're crazy to think that you can just walk in there. Ahh...and to think I saw you as a crazy American."
- ―Ulysses Klaue and Erik Killmonger
Following his escape from T'Challa, Klaue had N'Jadaka, going by the name of Killmonger, drop him off at an airfield with Limbani. Klaue promised to pay Killmonger for his rescue but Killmonger instead wanted to be transported to Wakanda. Klaue refused, so Killmonger shot Limbani. Klaue took Linda, Killmonger's lover, as a hostage for protection. After reassuring Linda, Killmonger shot her in the chest and injured Klaue in the process. Klaue stumbled to find cover, taking shelter behind some wrecked cars. Killmonger however, managed to sneak up on Klaue and shot him several times. Killmonger, then reveals his tattoo and his status as a Wakandan royal. Realizing that Killmonger was actually Wakandan, Klaue bursts into laughter before Killmonger shoots and kills him.
Killmonger took Klaue's corpse, placed it on a plane and took that plane to Wakanda. Arriving at the border, Killmonger dumps the body of Klaue at the feet of W'Kabi. This particularly pleases W'Kabi, as his parents were killed during Klaue's attack. Okoye learns of this development and contacts T'Challa, who was contemplating the actions of his father with Nakia. Having learned who Killmonger really is, T'Challa meets him at the palace as W'Kabi escorts him into the throne room. Presenting the body of Klaue as proof he is worthy of the throne, Killmonger stakes his claim to the throne much to the confusion of the Tribal Council, Shuri, and Ramonda. T'Challa whispered to Killmonger that the only reason he is still alive is that he now knows the truth. Killmonger then reveals his true identity out of anger, making him eligible for the throne. T'Challa accepts Killmoner's challenge and they set up the duel at Warrior Falls.
T'Challa at the falls is fed a liquid which strips him of the powers that the Heart-Shaped Herb grants. Killmonger and T'Challa are handed weapons with Killmonger snapping his spear in half. He takes off his shirt, revealing scars that he says are from killing people in Africa and the Middle East. He then states his intention to kill T'Challa for the throne. T'Challa and Killmonger duel, with T'Challa giving him multiple opportunities to yield and end the challenge. However, Killmonger gains the upper hand and severely injures T'Challa. Before he can kill T'Challa, Killmonger is stopped by Zuri who reveals the part he played in N'Jobu's death. Zuri begs Killmonger to let T'Challa live by letting him die instead, but Killmonger stabs Zuri through the heart while vowing to still kill T'Challa. T'Challa, enraged at Zuri's death, attempts to defeat Killmonger but is instead defeated himself. Killmonger throws T'Challa off the falls and into the raging waters below while declaring himself the winner and new king.
Realizing that Shuri and Ramonda were in danger, Nakia quickly evacuated them to the jungle. She then goes back to the palace to rescue the healed Everett, worried that he might be targeted by Killmonger. She runs into Okoye and urges her to fight Killmonger. Okoye refuses since she is loyal to the throne but still mourns the loss of T'Challa. Although she chooses to side with Killmonger, Okoye allows Nakia to leave the palace unharmed. Nakia the goes to the City of the Dead and watches Killmonger consume a Heart-Shaped Herb. Killmonger visits the Ancestral Plane and his father, which only reaffirms his view that Wakanda should conquer the world. He then orders the Heat-Shaped Herb to be burned, but Nakia steals one herb before they are all burned away. She meets up with Shuri, Ramonda, and Everett in the jungle. they realize there is only one place in Wakanda that Killmonger has no hold over, the land of the Jabari.
Killmonger holds a meeting of the Tribal Council. He states that Wakanda should have been helping the oppressed people of the world instead of remaining isolated for so long. He then introduces his plan of shipping Wakandan weaponry across the world and funding revolutions that will topple world governments and place them under the rule of Wakanda. His plan is met with some resistance, particularly Okoye. However, W'Kabi reaffirms Killmonger's plan, stating that he would like conquerors instead of being conquered. Killmonger sends his plans to the rest of the War Dogs around the world.
Meanwhile, Nakia, Shuri, Ramonda, and Everett finally arrive at the Jabari lands. They are quickly escorted to M'Baku himself. They beg him to intervene and fight Killmonger, even offering up the last of the Heart-Shaped Herb to him. Instead, he takes them deeper into the mountains and to a comatose T'Challa buried in snow. He tells them that some fishermen found T'Challa not long ago and the Jabari have been taking care of him. Since T'Challa cannot be moved from the snow otherwise he would die, they give him the Heart-Shaped herb and send it to the Astral Plane. T'Challa meets his father, who tells T'Challa it is time to rest. T'Challa instead tells his father and ancestors that they were wrong in keeping Wakanda isolated from the rest of the world and that Killmonger was created by them. He states that he will undo their mistakes and instead have Wakanda help the world. With his renewed sense of purpose, T'Challa awakens.
T'Challa, Nakia, Shuri, Everett, and Ramonda meet with M'Baku. Realizing what Killmonger intends to do, they all realize that they have to stop him. Shuri reveals that she took the Panther Habit from her lab before she fled with everyone. Now that T'Challa has a fighting chance against Killmonger, the group makes plans to stop Killmonger. M'Baku however, states that he will not involve the lives of Jabari in the conflict.
Killmonger, at Mount Bashenga, oversees the shipment of Wakandan weapons to War Dogs around the world. Suddenly a jet falls from the sky and explodes, with T'Challa emerging from the burning wreckage moments later. He announces that he is not dead, much to the joy of Okoye and that Killmonger's claim to the throne is still contested. Killmonger ignores and orders W'Kabi and the Border Tribe to kill T'Challa, an order that they obey. This causes the Dora Milaje to renounce their loyalty to Killmonger, with Okoye herself stating that Killmonger's hatred made him an unworthy king. She then orders Ayo and much of the Dora Milaje to assist T'Challa in fighting the Border Tribe. As Ayo and the others rush to T'Challa's aid, Okoye and three other Dora Milaje engage Killmonger.
With T'Challa creating a distraction above Nakia, Shuri and Everett sneak into Shuri's Lab and arm themselves. They tell Everett to stay behind as they need someone to pilot the Royal Talon Fighter to intercept the weapons before they leave the border. T'Challa, despite being outnumbered, manages to hold his own against the Border Tribe. Even when they call in rhinos. Okoye attempts to get the Panther Habit off Killmonger but is instead thrown back by the shockwave the suit generated. Nakia and Shuri emerge from the lab, throwing a Kimoyo Bead onto the Talon Flyer. This allows Everett to pilot the flyer and take out the weapons before they get past the border. Nakia and Shuri then engage Killmonger, but Nakia is thrown away while Shuri lays on the ground while being approached menacingly by Killmonger.
T'Challa sees this and tackles Killmonger into the mines below. He and Killmonger survive the fall and T'Challa orders Shuri to activate the train system in the hope that it will remove Killmonger's protection and allow T'Challa to defeat him. Shuri activates the system and T'Challa resumes his fight with Killmonger.
The tide of battle quickly turns against the T'Challa loyalists, with them being surrounded by the Border Tribe. They are given a chance to surrender but before anyone can respond M'Baku and the Jabari Tribe arrive and the tide of battle turns in favor of the loyalists. However, W'Kabi spots M'Baku in the chaos and mounts a rhino and starts charging at him. At the last minute, Okoye jumps in front of the rhino, stopping it and W'Kabi. W'Kabi dismounts from the rhino and asks Okoye is she would really kill, to which she responds without question. Realizing the harm he is causing W'Kabi surrenders, along with the rest of his tribe.
- "I don't need a suit to kill you. Your reign is over! We set up here safe and protected".
"You want us to become just like the people you hate so much. Divide and conquer the land that is needed!"
"Nah. I learned from my enemies. Beat them at their own game."
"You have become them! You will destroy the whole world, Wakanda included!
"The world took everything away from me! Everything I ever loved! But I'mma make sure we're even. I'mma track down anyone who would even think of being loyal to you! And I'mma put their ass in the dirt! Right next to Zuri!"
- ―Erik Killmonger and Black Panther
T'Challa and Killmonger continue their fight, each using the bursts of sound generated by the trains to defeat each other. Eventually, T'Challa picks a discarded spearhead and stabs Killmonger in the chest with it, even Killmonger compliments T'Challa on his defeat. Killmonger realizes that despite everything he has done, he's still a little boy chasing the stories of Wakanda. He tells T'Challa that his father often told him about the beauty of a sunset in Wakanda.
Deciding to show Killmonger a sunset, T'Challa picks him up and carries him to a nearby entrance to watch the sunset. T'Challa then offers to heal Killmonger hut Killmonger refuses, realizing that if he were to be healed he would spend the rest of his life in prison. He makes a final request to be buried at sea before he pulls the spear out of his chest, killing himself. T'Challa is left mourning his cousin as the sun sets.
- "Wakanda will no longer watch from the shadows. We can not. We must not. We will work to be an example of how we, as brothers and sisters on this earth, should treat each other. Now, more than ever, the illusions of division threaten our very existence. We all know the truth: more connects us than separates us. But in times of crisis the wise build bridges, while the foolish build barriers. We must find a way to look after one another as if we were one single tribe."
Killmonger's actions affected T'Challa and Wakanda. Realizing that by isolating themselves Wakanda was creating monsters like Killmonger, T'Challa resolved to help the world instead. He purchased his uncle's former apartment building and the buildings surrounding it with plans to turn it into the headquarters of an outreach program. He then appoints Nakia as the head of the social aspect of the program with Shuri heading up the scientific aspect also. T'Challa then announces his plans to the United Nations at the Vienna International Centre.
For his actions during the conflict M'Baku, and by extension, the Jabari Tribe were granted a seat on the Tribal Council. Despite the actions of W'Kabi, the Border Tribe was allowed to retain their seats on the council. Although the strength of the tribe was diminished, a fact that proved to be dangerous when the Battle of Wakanda commenced during 2018.
