The Mighty Nein: Cast and characters guide

Laura Bailey voices Jester Lavorre

Character: Jester is a member of The Might Nein who was raised in the Lavish Chateau. She's playful and chaotic. She's a blue tiefling cleric, and her weapon's a lollipop. However, when her pranks do not sit well with a politician, her mother sends her away from the city with Fjord. She also has an invisible best friend called Traveler.

Popular projects: The Legend of Vox Machina, Dispatch, and The Last of Us Part II.

Travis Willingham voices Fjord Stone

Character analysis: Fjord's also a member of The Might Nien, and he's a half-orc warlock who is recruited by Jester's mother to safely take her to Zadash. His weapon is a glowing sword. His blade, his powers, and his struggle between destiny and desire form one of the show's core arcs. He's eerily charming and has green skin with notable scars. Speaking to The Wrap, he revealed,

"With ‘Legend of Vox Machina,’ we had these 22-minute episodes and were really cramming a lot of story in there. With “The Mighty Nein,” the cast wanted more “runway” this time.The settings are more complex. The storylines are more intricate.”

Notable projects: The Legend of Vox Machina, Critical Role, Avengers Assemble, and Sofia the First.

Liam O'Brien as Caleb Widogast

Character analysis: Also a part of the Mighty Nein, he's a fire-wielding human wizard with a haunting past. His partnership with Nott becomes the emotional axis of the show. Their friendship is complicated, protective, and shaped by shared trauma. They met Beauregurad while they were traveling and soon became allies.

Known for: Asura's Wrath and Critical Role.

---

Sam Riegel as Nott the Brave

Character: Nott is a goblin rogue with nimble fingers, messy courage, and a porcelain mask that hides more than her identity. Her weapon? A unique crossbow with special abilities.

---

Marisha Ray as Beauregard "Beau" Lionett

Character: Also a member of The Mighty Nein, Beau is a human monk tied to the Cobalt Soul. She arrives skeptical, abrasive, and brilliant at reading people. Her investigation into corruption places her path squarely across the Nein's chaos. Her arc becomes central to the show's political spine as the conflict intensifies. Her first encounter with Caleb and Nott isn't pleasant, as they release her horse while she is on her way to meet someone pivotal.

Taliesin Jaffe voices Mollymauk Tealeaf

Mollymauk Molly is a lavender tiefling blood hunter. He has red eyes and curled horns. He's also a tarot card reader. His colorful appearance hides his fragmented memories, and the blood magic is as dangerous as it is enthralling.

---

Ashley Johnson as Yasha Nydoorin

Character: Yasha is a barbarian from Kryn lands, haunted by heavy loss and known by the title, "The Orphan Maker." However, she is set to appear only in the later adventures of The Mighty Nein.

---

Mathew Mercer as Essek Thelyss

Character: Essek is a Kryn wizard and a spy deeply entangled in the Dynasty politics. Brilliant, composed, and morally ambiguous, he becomes a key figure in the chase for the Beacon. His expertise in dunamancy, Wildemount's gravity-bending magic, is fascinating. He's brave, and he can go to any lengths to save his loved ones.

The Mighty Nein are not designed as traditional heroes. They are runaways, survivors, and skeptics who get entangled amid the war. Caleb and Nott bring the emotional gravity. Jester and Fjord carry optimism and doubt in equal measures. Beau's sharp edges become vital as they unravel political mysteries. Molly bursts through scenes with chaotic charm while Yasha brings quiet devastation.
