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.
