Trial Analysis Corporation
The head of Trial Analysis Corporation (TAC). He is a brilliant psychiatrist who uses his knowledge of human behavior to help his clients gain favorable outcomes in jury trials.
- Break the Haughty: Bull doesn't like people who act as if they're above other people and will find a way or two to cut his targets down to size.
- Dark and Troubled Past: Bess Johnson immediately sees through Bull's facade and says that he could only get so skilled at what he does by coming from a troubled home and having to learn how to read people in order to keep them happy and himself out of trouble. Turns out that he's the son of a man who defrauded his hometown when he was a kid.
- The Gadfly: He loves messing with people for his own amusement. There are occasions when his antics are germane to the case TAC is working on.
- Inner Monologue: Bull frequently imagines what people might say at any given moment.
- Limited Wardrobe: For most of Season 1, he almost always wears a dark suit and a white shirt with a cardigan. Chunk observes that the look is specifically tailored to make Bull noticeable but still inconspicuous enough to be able to observe others without arousing too much attention. Near the end of Season 1, he loses the cardigan and begins to wear a tie, along with his suits always having peaked lapels (for no apparent reason). Midway through Season 5, he loses the tie again.
- The glasses he always wears? Turns out they're just Purely Aesthetic Glasses. For "appearance".
- Loser Son of Loser Dad: His father defrauded an entire town out of a large sum of money and this resulted in Bull becoming a social pariah for simply being the man's son.
- My Greatest Failure: Bull wasn't able to help his sister out, who was in an abusive relationship even though she made the choice to stick through it.
- Nice to the Waiter: He believes that everyone is worthy of receiving attention and being celebrated, especially a person whose contributions are taken for granted. The most notable instance is his personal coaching of Liberty Davis to turn her from a meek backbencher into a legal star in her own right.
- Red Oni, Blue Oni: Red to Marissa's blue. He is a very passionate person who loves to manipulate people for fun and has a tendency to pursue seemingly illogical and tactically unsound gambits without ever explaining what he's doing with the simple expectation that people will trust him because he is who he is.
- Unkempt Beauty: He's handsome and clearly has expensive tastes but his pricey suits are almost always rumpled, his hair is tousled, and up until the end of Season 2 sports varying amounts of Perma-Stubble.
Bull's right hand in running TAC's affairs. She primarily oversees the company's operations from the office and is also in charge of client acquisition and relations. Prior to be being recruited to TAC, she had a career as a NSA analyst.
- Dark and Troubled Past: Her mother was a drug addict.
- The Lancer: Her role within the firm is to keep things running smoothly and to calm clients down when Bull's antics start getting outlandish.
- Ms. Exposition: Due to her being Bull's lancer, she is regularly providing reports and updates about how the trial of the week is progressing and, in the process, helping the TV viewer to understand the legal and psychological issues at hand.
- Red Oni, Blue Oni: Blue to Bull's red. She is a calming influence in an office full of passionate and, in Bull's case, unpredictable people.
TAC's image expert. His job is to make sure clients look presentable and to alter their appearances as necessary in order to subliminally influence juries in order to gain sympathy in the courtroom.

- Daddy Had a Good Reason for Abandoning You: Towards his daughter. She thinks he abandoned her; he never knew she existed.
- Only Known by Their Nickname: He's only ever addressed as "Chunk" and never by his given name.
- Papa Wolf: Although reluctantly crosses over with Deadbeat Dad due to the fact that he didn't know his daughter for years.
- Real Men Wear Pink: He is a fashion maven and dresses in very bright clothing with strong patterns. He is also a former football player and is built like a brick wall.
- Screw This, I'm Out of Here!: He was so well-known as a star football player that people still know him by sight at least two decades after his playing days ended. However, he decided to quit the day before the NFL draft because he felt he'd achieved everything he wanted to as a football player and was looking for a new challenge.
- The Social Expert: A role he sometimes shares with Marissa, he's known for being able to make witnesses more relatable, sympathetic, and understandable to the jury.

Recurring

- Meaningful Name: "Liberty" since she was freed from being under the shadow of Rutledge and was able to make a name for herself.
- Took a Level in Badass: She was originally quiet and meek but Bull quickly realized that she was capable of much more and carefully coached her through a very high-profile murder trial. Since then, she's become much more confident and assertive as a lawyer.

- Bitch in Sheep's Clothing: Her folksy demeanor is used to hide a stone cold ruthlessness.

-
The Scrappy: The general consensus is that the show is at its best when it focuses on the cases rather than the character side plots. Whenever Izzy is on screen, it is generally part of a character side plot. While she is fine in small doses, the show begins pushing her super hard starting in Season 5, much to the dismay of audiences.
Former
TAC's in-house attorney. His primary responsibility is to act out the lawyer's role in TAC's mock trials so that the company can measure mirror juries' reactions and gauge what sort of verdict real juries might come up with. He will also very occasionally go to trial if Bull brings in a pro bono client, although this isn't something he particularly enjoys doing.
In Season 5, Benny has joined a campaign to serve as New York's District Attorney. As of Season 6, he's living in Rome, Italy.
- Crusading Lawyer: He works with TAC because he believes that the innocent deserve the best chance possible in court.
- Screw This, I'm Outta Here: While he was a prosecutor he had overwhelming evidence to get a conviction but also knew that the defendant was innocent. Despite being pressured to get the win, he decided to take a moral stance and simply walked away from his job. Bull says he'd never have anyone else represent him because of this.
- Put on a Bus: Is written out of the series after season 5. In universe, they say he married an Italian woman and moved to Rome to be with her. In reality, Freddy Rodriguez was fired from the show following a workplace investigation.
TAC's resident computer expert. Although she is the company's go-to person for tech related matters, due to the fact that she is the youngest and newest employee, she doesn't fully understand the full scope of trial analysis nor why they should continue to use low-tech methods when everything is online.
- 10-Minute Retirement: Only a few episodes after Bull lets her go, her role in "Gag Order" helps win the case and Bull gives Cable her job back at the end of the episode, Of couse, awkwardly and apologetically.
- As You Know: Because she is the newest member of the team, she is the one asking questions about what Bull is doing and providing the TV audience with further information through the explanations given to her.
- Deadpan Snarker: Her preferred method for calling Jason out.
- Dropped a Bridge on Her: More like fell off a bridge. Season 3 opened on a very shitty note for Cable that spelled the end for her.
- Gender-Blender Name: You can be forgiven if you think that Cable is suppose to be a guy's name.
- Kill the Cutie: Cable went for a plunge off a broken bridge in New Jersey after renting a car and failing to stop in time. It's the first freaking scene of Season 3, too. NOT a fun way for her actress to move on from the show by any means.
- Naïve Newcomer: The youngest, and newest, member of TAC.
- Meaningful Name: "Cable" for a brilliant computer hacker. It shouldn't be a nickname, as it's even used in official situations, but if it is, it would be They Call Him "Sword".

- Only Known by Their Nickname: Like with Chunk, her teammates only ever address her as "Cable".

sexual harassment Dushku experienced on set.
