N'Jadaka / Killmonger
Voiced by: Keston John
The current leader of the Shadow Council. He was the mentor and eventual enemy of T'Challa AKA the Black Panther.
- Age Lift: He is a lot older than T'Challa in contrast to his film counterpart. Here, he is his former mentor.
- Big Bad: Of "Black Panther's Quest".
- Big Bad Duumvirate: His dialogue in Episode 20 when he said "Our plans" when leaving Tiger Shark in his cell, which somewhat reveals that he may not be the sole Big Bad.

- Comic-Book Movies Don't Use Codenames: Inverted in some case, as he was never called Erik.
- Disc-One Final Boss: Although he is the main antagonist of "Black Panther's Quest", he is not the last threat. The real last threat is Madame Masque.
- Hypocrite: He calls T'Challa "spoiled" and "weak", yet he himself believes he deserves to rule Wakanda because he is "strong", and often tilts the odds in his favor during their battles.
- The Man Behind the Man: This was eventually revealed to be his plan all along: bringing back Bask to act as a puppet ruler for him to enforce his will through.
- Pick on Someone Your Own Size: He is older than T'Challa and was his mentor, before becoming his enemy.
Tiger Shark
Tiger Shark
Voiced by: Matthew Mercer
Tiger Shark is a former general of Attuma, whome protest against the treaty and sides with the Shadow Council.
- Adaptation Species Change: He is a Shark Atlantean like the Ultimate version, rather than a mutated human of the main universe.
- The Dragon: Serves as Killmonger's enforcer. However, Killmonger abandons him later on in the season, and then takes this role to Elanna when she was too consumed by grief and vengeance over her father Attuma's death.
- Manipulative Bastard: He is able to convince Attuma's daughter to go to war with the surface.
- Token Non-Human: He is the only member of the Shadow Council who isn't entirely human, unless you count Princess Zanda because of her shapeshifting abilities.

- Disney Villain Death: In "King Breaker Part 2", he falls off the top of the palace, and to his doom.
- Light Is Not Good: His armor is white and silver, which are considered colors for the light theme and he is a villain.
- Mythology Gag:

- Powered Armor
Madame Masque
Whitney Frost / Madame Masque
Voiced by: Wynn Everett
A Hydra scientist researching vampires to have as new super soldiers.
She eventually joins Killmonger in Season 5.
- Adaptational Nice Guy: Whitney Frost is utterly insane in the comics, but here she is a more affable Well-Intentioned Extremist. She gradually warms up to Hawkeye as he refuses to sell her out to a vengeful Dracula when Hydra is more than willing to.
- Comic-Book Movies Don't Use Codenames: She is Madame Masque in the comics, but never gets to use the code name in her first appearance. Averted by the end of "Mask of the Panther".
- Composite Character: Her personality resembles more towards Doctor Doom and even wears the same green hood.
- Face–Heel Turn: She turns to villainy by the end of "Mask of the Panther".
- Final Boss: She is the last member of the Shadow Council that Black Panther, the Avengers and even Hydra face in the Season 5 finale as well as the last villain of the entire series.
- Going Down with the Ship: In "House of M", she insists on staying with Yamandi's Cutter as it drops out of the sky.
- Healing Hands: She gains this ability due to the mask in "House of M", where she is able to instantly heal Hawkeye's badly singed hands.

Ulysses Klaue
Ulysses Klaue
Voiced by: David Shaughnessy (seasons 1-4) , Trevor Devall (season 5-present)
A criminal who deals in vibranium.
He became a member of the Shadow Council in Season 5.
- Artificial Limbs: His lower left arm has been replaced by a sonic cannon.
- Doppelgänger Spin: His sonic cannon can create copies of himself made out of sound.
- Make Me Wanna Shout: His main weapon is a sonic cannon.
- Mythology Gag:
- He is modeled after the version seen in Avengers: Age of Ultron (even having his name spelt the same way), with the addition of his sonic cannon.
- His sonic clones are red (as is his giant sound form), in a nod to his comics self's living sound body, which was mostly bright red in color.
- The suit of vibranium armor he later wears looks exactly like a modernized version of his living sound form from the comics.
- Screw This, I'm Outta Here: In "King Breaker - Part 2". After being used by T'Challa and Hunter to escape the Shadow Council, Klaue angrily and indignantly states that he's had enough, and walks out on the entire conflict.
- Tattooed Crook: In keeping with his MCU self. One of the more notable tattoos is of a scorpion.
- Unexplained Recovery: He transforms into a massive creature of living sound energy, and apparently dies when this form is obliterated. He later returns and is inexplicably back to his human form, with no explanation given for how he's still alive. Even Captain America remarks that he should be dead.
- Unwitting Pawn: To Baron Zemo.
Princess Zanda
Princess Zanda
Voiced by: Mela Lee
A shape-shifter who was the ruler of Narobia and tried to invite T'Challa to a festival, but he refused. And so, she becomes a member of the Shadow Council.
- Abhorrent Admirer: To T'Challa.
- Adaptational Modesty: While Zanda always had her legs exposed in the comics, here she has them covered with blue tights.
- Adaptational Villainy: Princess Zanda in the comics was sometimes an ally to Black Panther. This version is a full-on villain.
- Capture and Replicate: Zanda does this twice:
- In "Mists of Attilan", she abducted Crystal some time ago to take her form.
- She does this again, this time with Black Widow off-screen and takes her form to turn the other Avengers against Black Panther by framing him for murdering Captain America.
- Death by Adaptation: She meets her end in the "King Breaker" arc by falling to her death.
- Disney Villain Death: In "King Breaker Part 2", during her confrontation with Black Panther, the floor crumbles under her, sending her falling to her death.
- Hate Sink: She is the most loathsome of the Shadow Council. When Captain America is supposedly killed trying to prevent the Crown from exploding, she impersonates Black Widow and successfully turns the Avengers against Black Panther by claiming that he killed Captain America. She later tries to violate a peace conference between Tony and Attuma by rigging Tony's suitcase armor to explode, therefore inciting a war between the surface and Atlantis. All these make her the most detestable character in the series. It's extremely satisfying to see her fall to her death.
- Inferiority Superiority Complex: As T'Challa notes in her debut episode, she has "self-esteem problems", and is obsessed with getting others to recognize her "greatness". She fell in with Shadow Council because they appealed to her desire for respect.
- Karmic Death: For all the trouble she's put Black Panther through by destroying his reputation, she pays the price by falling to her death.
- Manipulative Bitch: While impersonating Black Widow, she frames Black Panther for the murder of Captain America and turns the other Avengers against him.
- Spot the Imposter: In "King Breaker, Part 1", while she's still impersonating Natasha and sees Steve Rogers, alive and well, he asks her where she was born. She starts listing off locations, such as Timbuktu and Beijing. Steve immediately realizes that she's not Natasha, and T'Challa figures out her true identity.
- Villainous Princess: She is a Princess who uses her abilities to take on Black Widow's form and frame Black Panther for the seeming death of Captain America.
- Voluntary Shapeshifting: She is able to take many forms, most notably a red macaw.

The ruler of the Battleworld domain of Weirdworld who manipulates Bruce Banner into hunting Hulk.
