This are the main characters in the story.

Flash—Speed Force super speed

Bartholomew Henry "Barry" Allen (born March 14, 1989) is a scientist in the Criminal and Forensic Science Division of the Central City Police Department. He is the son of the late Henry and Nora Allen, the foster son turned son-in-law of Joe West, the husband of Iris West-Allen and the brother-in-law of Wally West, the archenemy of Eobard Thawne, as well as the father of his future children, Nora West-Allen and Bart Allen.

Barry's mother was murdered when he was 11 years old on March 18, 2000 and the blame was wrongfully placed on his father. He was taken in by Joe and he dedicated his life to proving his father's innocence. After the S.T.A.R. Labs particle accelerator exploded, causing a giant thundercloud to form, Barry was struck by lightning from a cloud, falling into a coma for nine months. When he woke up from his coma, Barry discovered that he had developed superhuman speed and various other abilities derived from it. Using these powers to protect Central City, he began acting as the meta-human superhero known as the Flash, initially referred to by the media as the Red Streak, the Streak and the Blur, stylized as the "Scarlet Speedster".

Barry spent the next several months fighting crime, taking down numerous meta-human villains and other criminal elements, assisted by Team Flash. All the while, he worked with Joe to get Henry out of prison and with Harrison Wells to get faster and develop his abilities. Barry later found out that the latter was the evil speedster Eobard Thawne from the future, having stolen Wells' identity, and the man who murdered his mother. In a final confrontation between the two, Eobard gave Barry the chance to undo what he did in exchange for assistance in returning to his time. Barry decided against doing this, which ultimately led to Eobard's ancestor killing himself to erase Eobard from existence.

Several months later, Barry finally saw his dad become a free man using a video will left by Eobard. It was also at this time Barry came under attack by meta-humans from Earth-2 led by Zoom, another evil speedster who needed Barry's speed to prevent himself from dying. Barry is eventually forced to comply to save Wally West, temporarily becoming a normal human again until Team Flash worked to get him his speed back. Barry soon after defeated Zoom, but not before his father is murdered in front of him. This sends Barry into a depression, and, not thinking clearly, goes back in time to save his mother, creating another timeline.

After Barry undid Flashpoint, a time loop was created with a possible future of Iris dying in front of Barry. A time remnant of Barry from this future was created, and after being shunned for not being the original Barry he became a powerful, mythical, armoured speedster, known as Savitar. After his transformation into Savitar, he sought to ensure his existence by murdering Iris in order to drive his younger self into the circumstances that led to his creation. When battling his younger self he referred to himself as the Future Flash. He was later erased from existence after he failed to recreate the circumstances of his own creation. However, this victory was short-lived; Barry was forced to enter and remain in the Speed Force indefinitely to save the world.

Barry was eventually freed thanks to the efforts of Team Flash, though in the process accidentally created more meta-humans. The self-described Fastest Man Alive was forced to take on the Fastest Mind Alive, Clifford DeVoe, who wished to revert humanity to a time before technology. It was also during this time Iris and Barry got married after fighting invaders from Earth-X and Team Flash first encountered Nora West-Allen, not realising until much later on that she was the daughter of Barry and Iris from the future who had traveled back in time to help stop Cicada. Although conflict arose when it came to light that Nora was working with Eobard Thawne in secret, the three of them grew immensely close. However, when Cicada II was defeated, a new timeline was formed, resulting in Nora being erased from the timeline, leaving Barry and Iris devastated.

When Barry was "possessed" by Ramsey Rosso/Bloodwork after the latter infected Barry's blood cells while he was saving Ralph's life,[6] Cisco nicknamed him Dark Flash. Barry was restored to normal when Allegra Garcia used her powers to cure everyone affected by Rosso's disease.

During the Anti-Monitor Crisis, Barry was revealed to be the Paragon of Love. He was one of the only surviving individuals from Earth-1 after the destruction of the Multiverse in the Anti-Monitor Crisis. However, thanks to Oliver's sacrifice, he and the other Paragons were able to defeat the Anti-Monitor after Earth-Prime was created. Barry also founded the Crisis team and worked to honor the memory of his close friend and mentor.

Following the destruction of the Speed Force, Barry's powers slowly started to run out, forcing him and the team to seek out a way to create a new Speed Force. He also faced new enemies in Godspeed, Black Hole, and Eva McCulloch. While the artificial Speed Force machine succeeded in restoring his speed, it came at the price of Barry losing his morals and emotional attachment, forcing them to destroy the machine. After the sudden return and help of the resurrected Earth-1 Harrison Wells, Team Flash found an alternate usage for the Speed Force machine. Channeling the residual Speed Force energy Iris from her various interactions with speedsters through hers and Barry's love for others into the machine, they were able to restore the Speed Force and Barry's powers.

However, unbeknownst to Barry, the restoration of the Speed Force also resulted in the birth of three other forces; the Strength Force, the Sage Force and the Still Force. These forces allegedly attacked the Speed Force, forcing her to flee into a human form. Barry went head to head with Fuerza, Psych and Deon Owens, the hosts of the respective forces. However, it transpired that the Speed Force desired to kill all the forces, killing their hosts in the process, an act Barry was staunchly against. Instead, he opted to travel back in time and prevent the existence of the forces to begin with; but he ultimately changed his mind and allowed their existence; while managing to broker peace between the forces.

Soon after, Barry and his team are forced to contend with the brewing Godspeed War, masterminded by an artificial speedster August Heart, who seeks to become the God of Speed by stealing Barry's recently enhanced speed. It's only with the help of many speedster allies, including the revived Eobard Thawne, that August was defeated and incarcerated in Iron Heights.

Six months later the powerful alien Despero shows up in Central City determined to kill Barry for supposedly creating an event that will end the world. After proving his honourableness to the alien, Despero agrees to give Barry seven days to prove he will not cause Armageddon. [8] Unfortunately, events quickly turn sour as Barry is suspended from his job as a CSI at the CCPD, before learning that S.T.A.R. Labs is being shut down and demolished. Barry is forced to destroy Gideon to protect his identity. Not long afterwards, Barry encounters Xotar, where he falls to prey to her abilities, causing him to temporarily lose his mind and mindlessly attack his friends, until he snaps out of it. After later defeating Xotar, Barry, for unknown reasons, attacks Central City, an event caught on the news, although he does not remember doing it. After mentioning celebrating with Joe and Cecile, Barry is stunned to learn that Joe was dead, and had been for six months. After escaping another attack from Despero, Barry, feeling overwhelmed by recent events, calls for Black Lightning's help at the Hall of Justice. After discovering that Eobard Thawne was behind it all along, he was able to defeat Despero and remove Thawne's speed, finally ending Armageddon.

Judy Hopps

Judy is fiercely optimistic and independent. Since childhood, she had harbored a dream to become a police officer, solely for the opportunity to help those in need and make the world a better place. She cares deeply for the well-being of others, and would be more than happy to offer a helping hand to them; this includes her family, friends, Mrs. Otterton's despair over the disappearance of her husband, and even Nick Wilde. She has a large heart, and although she tends to keep her emotions under control—and even under wraps—a majority of the time, she is capable of expressing her true feelings in a genuine, powerful light. This is mostly seen with Nick, whose feelings and companionship she highly values, motivating her to prevent her own ambitions from harming others.

Due to being a rabbit, a species unassociated with such a high-stakes occupation, Judy faced continuous doubt and underestimation from those around her, from her parents to local bullies. Nevertheless, she used her opposers as a means to increase her determination and became progressively more insistent on reaching her goals than ever before with each naysayer; she believed in the importance of always trying and making an effort to reach your goals, no matter what. Her goal was to eventually become a resident and local officer of Zootopia, a city where predator and prey supposedly live together in peace and harmony (unlike the burrows), believing she will be quickly accepted amongst her peers and neighbors in spite of her species. Unfortunately, she was too idealistic for her own good in this regard. She found herself unprepared to face the negative aspects that lie within the city upon her first residential day, leaving her to fall victim to bigotry, stereotype, and manipulation.
However, her optimism and determination to be a police officer tends to lead her to be, at times, overzealous, overconfident, and impulsive. As a parking enforcement officer, she gave 201 tickets to anyone whose cars had been in a parking meter too long (including herself) before noon just to show up Chief Bogo's doubts about her, arrested Duke Weaselton for stealing (even though parking enforcement officers cannot arrest someone, which was disclosed from a furious Bogo), and had nearly gotten herself killed on multiple occasions during her first case.
Despite the odds, Judy remains optimistic and determined, adapting herself to the environment of Zootopia and those around her to build up both the way she presents herself and pursue her goals. She is clever, kind, and resourceful, which proves to be her greatest asset. She tarnishes the stereotype of a "dumb bunny", being intelligent enough to outsmart professional con artist, Nick Wilde, several times. Months of training at the Zootopia Police Academy has also left her tactical, with an impressive amount of physical prowess. During times of chaos, she can quickly take charge of a situation by concocting an efficient plan on the spot, being daring enough to take dangerous chances, in order to potentially end the day victorious. More often than not, Judy comes out successful as a result of this.

From childhood, Judy has held the belief that predators and prey should be treated equally and made attempts to refrain from acting on bigotry herself. However, due to her childhood experiences, having been bullied by a fox, Judy has a mild fear of predators (mainly foxes), whether she wanted to admit it or not; so much so that it manifests as unintentional prejudice itself. After being pestered into taking a canister of fox repellent during her move from Bunnyburrow to Zootopia, Judy made the conscious decision to keep the canister by her side for a majority of the film. When she first spotted Nick snooping about the streets, she immediately assumed him to be in the midst of a scam, following and nearly assaulting him with the canister all due to the fact that he was a fox. When it appears that Nick was merely an innocent civilian looking to buy ice cream for his son, she felt ashamed of her bigotry, which caused her to overcompensate in hopes of redeeming herself, wanting to be progressive and unbiased while hypocritically claiming others to be otherwise; this would ultimately make her a pawn to Nick's scams, in the end, while simultaneously teaching her a valuable lesson reflecting both life, and herself.
The events of Judy's first few months in Zootopia would ultimately blossom a more mature, practical, diligent, and legitimately progressive individual. Through her experiences, she discovers the downside of having an overly idealistic mentality carry you through life, and that the world can be a problematic place, filled with issues such as prejudice and stereotype, learning that all mammals—be they predator or prey, foxes or rabbits—can be victims of bigotry, even when it is unintentional. No matter the species, all animals having feelings, hopes, and dreams, all of which can be destroyed by preconceived notions and constant underestimation. As such, all should strive to live and accept one another for who they are inside, and not the stereotypes they have been labeled as by society. Even with this new outlook on life, Judy would still contend to the method of trying. Using her success and experiences as proof, she implores those around her to make an effort to see beyond stereotypes, to prove your worth and reach your goals in spite of all that may go against you, with the belief that these positive actions can ultimately lead to a better world, becoming the physical representation of Zootopia's meaningful motto "Anyone can be anything."

Nick Wilde

Nick came from a poor background living with his mother, Mrs. Wilde (his father is never mentioned or seen, except in the original version of the film). As a child, Nick had a dream to join the local Junior Ranger Scouts, for the goal of receiving genuine acceptance. When he was 8 or 9 years old, his mother scraped up enough money to buy a brand new scout uniform, allowing him the opportunity to join the division. Though he was the only predator there, the only fox, Nick attended his initiation with confidence and zeal, unknowingly walking right into a trap. The "initiation" turned out to be a cruel prank and Nick was ridiculed, brutally beaten, and muzzled by the other scouts for being a fox (as foxes are considered among the most vile and untrustworthy species of mammals in Zootopia). After running outside to escape his tormentors, Nick tore off the muzzle and broke down in tears, developing a triggering fear of muzzles and dislike towards prey, and bigoted mammals. From that moment forward, Nick vowed to never expose his true vulnerability to others, resulting in the fox presenting himself as stoic and unreachable. This unjust treatment continued well throughout his lifetime, apparent during his adulthood shown in the film, which would only heighten Nick's cynicism. Some of these instances include Nick's interaction with the prejudiced Jerry Jumbeaux, Jr., who specifically states that he has the right to refuse service to anyone, and abuses this power against Nick, openly due to the former's distrust towards foxes. Chief Bogo also displayed this behavior when Officer Judy Hopps, at one point, called Nick forth as a key witness for her case; Bogo unabashedly scoffed at the idea of a fox being trustworthy enough to have its voice heard, thus refusing to listen to his testimony. As a result of this treatment, Nick declared that if the world viewed foxes as nothing more than sly, vile and untrustworthy scoundrels, he should not only accept it, but embrace it, subsequently doing so by becoming a successful con artist. At some point during his status as a con artist, Nick fell in with Mr. Big, a feared arctic shrew crime boss, developing a stable partnership with him. Mr. Big liked and trusted the fox, welcoming him into his home and even introducing him to his grandmother, who made him a cannoli. However, Nick later took advantage of Mr. Big's trust by selling him a very expensive wool rug secretly made from the fur of a skunk's rear end. Feeling betrayed and disrespected, Mr. Big turned Nick away, threatening to kill him if they ever met again. By the start of the film, Nick appears to be well-off, claiming to have made $200 on a daily basis since the age of twelve (though the accuracy of these claims is questionable). He often works and splits the day's earnings with his quick-tempered partner and fellow fox, Finnick. In Disney Zootopia: Friends to the Rescue, young Nick is described as sweet, friendly, and mischievous, and is noted to have a natural ability to make others smile and laugh, by replacing the magician, who called in sick, for his childhood friend, Hedy's birthday.

Nick Wilde is shifty, sly, and cunning, traits supposedly common to all foxes. He is easygoing and slick, easily conning and tricking others through his charm and friendly demeanor. He nearly always has a sly smile on his face and seems unfazed throughout most of the film, as he later reveals that because of the numerous years of suffering from prejudice and stereotypes that came with being a fox, he decided on two things; he would never let anyone know they got to him, and if the world only ever saw foxes as sly scoundrels, then he would be just that. This led him to be cynical and pessimistic of the world, and he came believe that animals can only be what they are, not what they want to be. He is very street smart and intelligent, and is also good at telling what kind of person someone is, as he was able to correctly guess upon simply meeting Judy that she was from a family of carrot farmers and graduated top of her class with high dreams of making it big and living in a place like Zootopia where it seemed like everything was great because people could live equally before displaying his pessimistic side and stating she would never make it and would return home.
Because he is a con artist, he is tricky and knows how to get out of sticky situations using his words and knows how to get around the city easily managing to evade Judy and tricking her into stepping into wet cement. Despite being a con artist (or perhaps because of it), he has numerous friends and connections (most of whom are shady characters to begin with). He also got in trouble with at least one mob boss, notably Mr. Big (though by the end of the film they seem to have put the matter under the skunk butt rug). He enjoys being sarcastic and poking fun at others, particularly Judy, since she was much more serious than him and was a bunny, on occasion citing stereotypes such as carrot farmer and dumb bunny toward her.
