Synopsis
Callaghan's crimes in San Fransokyo weren't the only incidents to inspire the rise of villains: his tragic death also sparked a mysterious Robin Hood-esque vigilante to not just break out Ian (aka Hardlight) and Mel Meyer from prison, but also set their sights on the one true mark; Alistair Krei. But when Big Hero 6 go to confront this vigilante, it was someone they did not expect.

Big Hero 6

 * Hiro Hamada (voiced by Ryan Potter)-The founder and leader of Big Hero 6. At 18 years of age, he has grown taller, even surpassing Karmi's height by the head, his hair having grown out more at neck's length and brushed down with bangs swept to the side, and his body is bulkier and leaner. As a civilian, he wears a black blazer jacket over a blue dress shirt, light brown slip-on jeans, and mint green sneakers in honor of his brother, Tadashi. As a superhero, he's updated to a black full bodysuit with indigo armor, his gloves are much slimmer with red circles on the palms where the magnets are located, his black and indigo forearm gauntlets are less thicker but more re-inforced to deflect attacks and generate forcefields, and black steel-toed motorcycle boots. Plus, his helmet is retrofitted with the neurotransmitter to control his microbots that he keeps in his canteen waistbag, and his bodysuit is updated with nano-dex to give him more agility and flexibility, making him more fluid like a ninja.
 * Go Go Tomago (voiced by Jamie Chung)-One of the members of Big Hero 6. Her hair has grown out more and less scruffy than it was, and is neatly parted with purple highlights while braided over the left shoulder. As a civilian, she wears a white, purple orchid-printed, hanbok-style halter top with a black leather bolero jacket over it, black choker gloves, dark gray high-waisted, denim pants, and black tall boots with a side zipper and buckle near the edge. As a superhero, she's updated to a full-bodied armor vaguely similar to her Ultra Armor, only her Mag-Lev Disks can detach and reattach from her back, and the ones on her legs fan out into a half circle, forming one Hover Disk.
 * Wasabi (voiced by Khary Payton)-One of the members of Big Hero 6. He trimmed his beard to a French cut, and his dreads have grown out more, now styled into a ponytail. As a civilian, he wears a white, short dress shirt with a sweatvest the same color as his sweater, dark gray trousers, and black dress shoes. As a superhero, his dreads are in a bun tied with a red hairband and retains his black jikatabi boots, only he now wears a Flexible Display Technology Bodysuit under his armor to give him a more ninja-like appearance, and his Plasma Blades are infused with refined titanium Hiro requested to Honey Lemon to fend off Momokase's graphene weapons much easily.
 * Honey Lemon (voiced by Génesis Rodriguez)-One of the members of Big Hero 6. Her hair is styled in a long braid with thick bangs covering her forehead. As a superhero, she wears a sleeveless, misty rose dress with a carnation pink tunic over it, lavender pink leggings, and replaces her platform heels with midwedges for the sake of stopping being called "tall" all the time. As a superhero, she's updated to a black full bodysuit with a lavender armor dress and matching midwedges. Her Chem-Purse is now replaced with a Chem-Waistbag that will provide her mobility for combat.
 * Frederick "Fred" Frederickson IV (voiced by Liam O'Brien)-One of the members of Big Hero 6. He has a more mature, decent, unhunched appearance compared to his unkempt style, and his hair has grown out into a mullet to honor his father's classic lifestyle. As a civilian, he replaces his monster hat with a backwards baseball cap to honor Tadashi, and wears a short blue hoodie with his signature kaiju logo, red undershirt, denim trousers, and yellow converse high tops. As a superhero, his battlesuit is a combination of his default and new ultra armor. The material is made with the Flexible Display Technology fabric fuses with refined titanium to make the suit water-proof so that the camouflage ability doesn't short out.
 * Baymax (voiced by Scott Adsit)-Hiro's personal healthcare companion, and the final member of Big Hero 6. His vinyl material is upgraded with fusions of platinum, carbon, and resin, making it tear-proof and bouncy as rubber. As a superhero, his battlesuit is a combination of super armor and new ultra armor, giving him more durability even upon impact.

Allies

 * Professor Granville (voiced by CCH Pounder)-The new dean of SFIT, and ally of Big Hero 6. Her hair has grown out more like in her earlier years as a professor, but pulled back in a ponytail with a gold hair clip. As a civilian, she kept her gold necklace, but now wears a black turtleneck dress with a dark gray pencil skirt, a black black belt at the waist, dark gray tights, and black flats. As a superhero, she wears a golden yellow armor dress with chrome yellow sleeves, metallic gold leggings, and golden brown knee-high flats.

 * Karmi (voiced by Awkwafina)-The current student of SFIT, a love interest of Hiro, and ally of Big Hero 6.

As a civilian, she wears a cream-colored, long-sleeved blouse with the cold shoulder, deep red earrings, red wristbands with yellow beads, orange high-waisted denim skirt, black capri-style leggings, and cream-colored flats. As a superhero, she wears a full black bodysuit with a chrome orange chest armor, gauntlets, and skirt, white forearm gloves, a dark orange belt with a gold hexagon-shaped belt buckle, and chrome orange boots with fronts the same shape as her buckle. Her visor has an electric indigo tint along with a hidden microphone, and her gauntlets are equipped with launchers at the ends of her wrist for her extra-dermal nano-receptors to knock her enemies out unconscious.
 * Wendy Wower (voiced by Erica Lindbeck)-The real scientist who wrote her thesis, a host of her own TV show, "Wendy Wower's Science Hour", and an ally of Big Hero 6. Her hair is grown out more at an elbow's length and dyed in neon green with turquoise streaks, now styled into a braid with curved bangs.

As a superhero, she wears a blue-gray dress with black sleeves and tights, blue-gray boots, and white armor-like tunic with grayish-purple around the shoulders and a yellow belt at the waist, along with gauntlets, greaves, and a helmet like Go Go's to match. The visor on her helmet has an aquamarine tint, and she carries an axe guitar with titanium-fused plasma blades hidden in the body, and a laser gun in the headstock.
 * Mini-Max (voiced by John Michael Higgins)-A tiny robot invented by Hiro to assist Fred, and ally of Big Hero 6. He is the close look-alike of Baymax, but with a head bigger than his body and has blue eyes.

As a civilian, she wears a black, long, sleeveless jacket with spring green zipper and stripes over an office green mid-sleeved shirt, light sea green slip-on jeans, and navy blue denim boots with tan heels and toes. As a superhero, she wears a full light blue and dark blue bodysuit, which are the colors of a rookie police officer, with the excess fabric hanging hanging above the knees like a skirt, black gloves, dark gray armor, gauntlets and greaves, and black boots. Her navy blue helmet's visor fades from red on top to blue on the bottom like police lights, and the gauntlets shoot out elastic cuffs to keep the enemies restrained.
 * Roddy Blair (voiced by Nolan North)-The architect of BH6's headquarters and inventor of Basemax, the team's AI. He now has a lean and stocky build, his beard is trimmed with a five o'clock shadow, and his hair has grown out at a shoulder's length. After learning of the team's identities, Roddy now wears long-sleeved overalls with a halfway zipper and having the BH6 logo, which is a blue hexagon with the red number six in the center, a blue cap, dark gray thick gloves, his tool belt, and black boots.
 * Basemax (voiced by Zelda Williams)-Big Hero 6's AI of their base invented by Roddy Blair. Using the parts for creating Baymax, the Skymaxes, Big Hero 6's gear, and the Bunny Shuttle, she manages to create a robotic body for herself. It is a slender build out of a cobalt blue metal plating that covers her carbon-fiber skeleton to give her a feminine appearance, biomechanical arms and legs to resemble human limbs, and a helmet for the head with a dark cyan screen to project a female human-like face intending to be beautiful. Her "hair" is made of strips of neoprene and vinyl that allows her to change hairstyles in any way she wants. For "clothing", Basemax can materialize titanium from a hexagon embedded in her chest for projecting crystal-based nanoparticles into a suit or a tunic.
