In the Battleworld domain of Weirdworld, Black Widow and Captain Marvel find that Bruce Banner is working with Morgan le Fay to hunt down the Hulk. However, they eventually learn that Morgan is planning to harness the Hulk's power to take over Battleworld. As such, Bruce reconciles with Hulk and re-fuses with him to stop Morgan.

Hawkeye, Vision, Loki, and Wasp head to Westland, an old west domain to find Doctor Strange. They find him working as their doctor in the midst of an attack by a Kree Conquest Hive where Hawkeye is temporarily blinded. After running into Rocket Raccoon and Groot after their ship crashed, Vision finds Jane Foster who has been operating as Westland's sheriff under the alias of "Calamity Jane Foster."

Captain America and Iron Man are captured by the Beyonder and the villain team he has assembled from Absorbing Man, Ares, Crimson Widow, and MODOK. While Captain America works to evade the villains in Beyonder's lair, Iron Man is shown by Beyonder the truth of his experiment.

Before they can use the Bifrost to undo Battleworld, the Avengers must defeat Ares and an army of Ghost Riders. As Doctor Strange and Loki work on the Bifrost, Thor gives Mjolnir to Jane Foster, transforming her into a new version of Thor.

After Loki becomes the Sorcerer Supreme following Beyonder's defeat, the Avengers are the only force standing between him and the domination of the universe even after he defeated Odin. While the Avengers and the New Avengers fight an army of Mindless Ones, Doctor Strange and Jane Foster rescue Thor even when Loki unleashes the All Dark.

Part 1: Black Panther holds a party to give the Avengers and their guests a formal introduction of Shuri until Attuma's general Tiger Shark attacks. When Tiger Shark blows the Horn of Neptune, it summons a sea monster as Thor, Captain Marvel, and Ms. Marvel work to keep it from destroying the bridge.

---

Part 2: As the Avengers fight the straggling Atlantean soldiers, Tiger Shark has invaded the Wakandan embassy as Black Panther rescues Shuri from him. After the Avengers take down some of his followers, Tiger Shark makes his way to the embassy to steal a jar for his mysterious benefactor.

Suspicious of Attuma following Tiger Shark's defeat, Black Panther and Shuri go on a dangerous mission to Atlantis. As Black Panther infiltrates the palace to get answers from an imprisoned Tiger Shark on why he was after a Wakandan crest, Shuri mingles with the diplomats where she runs into Wakanda's ambassador N'Jadaka who has a secret agenda that Black Panther and Attuma do not know about.

Black Panther and Shuri return to Wakanda to look for other enemies in light of N'Jadaka and Tiger Shark being associated with the Shadow Council. They run into Black Panther's adopted brother White Wolf who is said to have a list of Shadow Council operatives. As Black Panther chases after him, they are attacked by M'Baku and his mercenaries who have allied with the Shadow Council.

After apprehending the Wakandan N'Basa who is on the Shadow Council's side, Black Panther informs Captain America in a transmission that Baron Zemo was a member of the Shadow Council in the 1940s. Tracking Zemo to Château le Fay in Switzerland, Black Panther finds that he is planning to destroy his father's files before it falls into the wrong hands. Both of them must work together when Tiger Shark targets the files for the Shadow Council.

After he and the Dora Milaje thwart Crossbones' plan to invade Wakanda, Black Panther brings Ms. Marvel on a mission to Attilan. Due to T'Challa's grandfather T'Chanda previously making a promise to them, Black Bolt and Medusa are reluctant to give up the claw piece of a key. Amidst this, they deal with Princess Zanda of Narobia who is on the Shadow Council.

As Baron Zemo continues to decrypt his father's files, T'Challa finds that Wakanda's computers have been hacked and traces it to Pele Pele which T'Chaka and N'Jadaka could not develop due to volcanic activities. Upon arrival, he is hunted by Kraven the Hunter as part of the latest episode of "Kraven's Amazing Hunt". Meanwhile, Shuri and Zemo work to eliminate the Shadow Council's virus from Wakanda's computer systems.

After attending an event held by Tony Stark that followed him thwarting Crossbones' bank robbery, Black Panther answers a distress signal at a Wakandan village that has been attacked by a group of monsters called the Kawulo. Black Panther discovers that Ulysses Klaue is behind the attacks with the help of some mercenaries and mutated bats, controlling the latter using special collars.

After thwarting Taskmaster's heist of a hyper-cannon, Black Panther heads to Antarctica with Captain America where they meet with Hawkeye and Whitney Frost at S.H.I.E.L.D.'s Zebra Base. They find a Wakandan submarine called Yemandi's Cutter in ice as Black Panther suspects that the final key fragment is on board.

While surprised that Baron Zemo is in Black Panther's company, Captain America meets with Black Panther and Shuri to learn about the Panther Key that the Shadow Council used to weaponize a powerful Wakandan artifact. When the key is stolen during a blackout, M'Baku escapes from his cell as White Wolf has his own plans to keep the Panther Key safe which conflicts with Captain America and Black Panther's plans for it.

At a hidden observatory, Black Panther, Captain America, Shuri, and Baron Zemo find the location of the Shrouded Temple when they are transported to the other side of the Moon. After seeing a recorded transmission from T'Chanda on the Shrouded Temple's interface, the four find the door containing the Crown artifact as the Shrouded Temple comes under attack by Killmonger, Ulysses Klaue, Madame Masque, and Tiger Shark, who knock it out of orbit.

Following the defeat of Madame Masque and Ulysses Klaue, Black Panther, Captain America, Shuri, and Baron Zemo look for the Crown that the Shadow Council is after as Princess Zanda and Tiger Shark catch up to them and assist Killmonger. The rest of the Avengers show up to help fight the Shadow Council operatives until Baron Zemo puts the crown on himself and starts to become unstable due to not being Wakandan.

After Captain America supposedly sacrifices himself to prevent the Crown from emitting a destructive pulse, Black Panther and Shuri work to get the Crown back to Wakanda before it explodes. The Avengers pursue them after Black Widow claimed that Black Panther "killed" Captain America. As Black Panther is unable to reason with the Avengers with all his secrets coming to light, Black Panther and Shuri are on their own safeguarding the Crown until they can return to Wakanda.

Part 1: Tony Stark holds a memorial for Captain America following his claimed death and states that Black Panther was responsible while denying any knowledge of the Wakanda weapons. In addition, Tony also mentions that the nations of the world have pledged unity against Wakanda including Atlantis. After training, Black Panther sneaks into the United States to track down Ulysses Klaue and Killmonger while evading the Avengers and Winter Soldier.

---

Part 2: After Black Panther is incarcerated at the Vault, he begins to get his answers from Ulysses Klaue. He states that Killmonger is after the Heart of Wakanda and agrees to give him information if they escape from the Vault. However, Klaue double-crosses Black Panther as Adrian Toomes shows up to help him. When Toomes gets his Vulture suit back and decides to tie up some loose ends, Black Panther must work with Spider-Man to defeat Vulture.

Now that they have Ulysses Klaue in their possession, Black Panther and Shuri bring him to the Hall of Royals, the burial ground of previous Wakandan leaders. Black Panther uses the Crown to learn about his grandfather T'Chanda's past, where he, Captain America, and Peggy Carter battled Hydra operatives and the Shadow Council.

Note: Stan Lee makes a posthumous cameo appearance as an army general.

After reviewing T'Chanda's memories, Black Panther uses the Crown to learn about the past of Queen Yemandi. She previously battled Thor to gain the Spear of Bashenga before they were forced to work together to stop Morgan le Fay. In the process, Morgan forges the Crown from Bashenga's Core.

After reviewing Yemandi's memories, Black Panther uses the Crown to learn about the past of Wakanda's founder Bashenga. He and his twin sister Bask discovered Vibranium while fleeing from Atlantean warriors and used it to develop Wakanda into a technologically advanced society. However, Bask realizes that Black Panther is watching the events unfold and uses her powers to trap his mind inside the Crown.

Part 1: To get on the good side of Attuma, his daughter Elanna, and Commander Orka, Iron Man has Black Widow and Hawkeye apprehend Killmonger and Tiger Shark. After Captain America escapes the Crown's pocket dimension, he figures out that Black Widow was actually Princess Zanda in disguise. With Captain America still recuperating and Shuri keeping an eye on Bask, Black Panther frees White Wolf to get into Atlantis and stop the Shadow Council from starting a war.

---

Part 2: With Zanda's plot exposed and Lady Elanna rushing Hawkeye to the infirmary, White Wolf makes his way to the Atlantean throne room to disable the bomb that Zanda wired in Tony Stark's armor. Once the bomb is disposed of, Black Panther, White Wolf, Elanna, Attuma, and Tony Stark must work together to save Atlantis before it is destroyed while also fighting an escaped Killmonger. The Avengers take Killmonger prisoner to find out where the real Black Widow is being held captive, while Elanna releases Tiger Shark to prepare for her revenge on Killmonger and a planned war with the surface world.

With the information given to them by Killmonger, Black Panther, Iron Man, and Captain America look for the Shadow Council's base to find Black Widow. They trace her location to an island that negates all technology, where the Council created plant monsters as part of their super soldier program. Afterwards, Black Panther discovers that Bask has awoken and has sided with Killmonger and Madame Masque while also freeing M'Baku and Ulysses Klaue.

Bask has defeated Black Panther and takes control of Wakanda. Before Bask can have Black Panther executed, White Wolf rescues Black Panther and they take Ulysses Klaue hostage. In retaliation for Bask firing Madame Masque's laser on Atlantis, Elanna and Tiger Shark lead the Atlanteans against her. Amidst this, Bask sacrifices herself to stop the laser and Tiger Shark kills White Wolf. This leads Black Panther to attack Tiger Shark before eventually standing down. Shuri is then crowned queen of Wakanda as the two nations make peace.

The Avengers raid a HYDRA base and find that Arnim Zola has been dismantled. They run into Black Panther, who was pursuing Madame Masque, and are soon attacked by Red Skull, Crossbones, Crimson Widow and Typhoid Mary. After Madame Masque takes Iron Man and Red Skull captive, Black Panther and Hawkeye must put aside their differences and past grudges to stop her.
