- The Alcoholic: He drinks heavily as a way of coping with his PTSD.
- A Father to His Men: He looks after them, especially Bear since he looks at him like a father figure.
- Create Your Own Villain: By killing Omar, who had surrendered, he just made Nasry into a terrorist willing to go after Americans everywhere. And he makes it a priority to catch him.

- Dented Iron: Caulder has been in close proximity to too many explosions and suffers from constant ringing in the ears and dizziness in the second season. After he collapses and Dharma takes him to a hospital, a neurologist informs him he has extensive brain damage and that this will kill him unless he avoids such situations, which means resigning from the military.

- Not What I Signed on For: Alex didn't sign up just to kill terrorists who are defenseless and those who choose to surrender.

Henry the 8th's first wife, whom he ultimately divorced to marry Anne Boleyn.
- Color-Coded Characters: Yellow/Gold
- Gratuitous Spanish: Like both Annes and their gratuitous language. Justified as she was from Spain.
- Heir Club for Men: Protests that she did have a child with Henry, but it wasn't enough if that child wasn't a boy. Joke's on Henry because in the end, Mary would become queen.
- Rage Breaking Point: Catherine was disregarded as women were at the time, and clearly cheated on. Being divorced, especially as she was a fervent Catholic, was the straw that broke the camel's back.
- Stiff Upper Lip: "Had my golden rule/Gotta keep my cool, yeah baby." No matter what life (or Henry) threw at her, she never showed anger or sorrow — right up until Henry said he wanted an annulment.
- 0% Approval Rating: For replacing (and in the musical, openly dissing) the popular Catherine of Aragon.
- Queens: Wow, Anne, way to make the country hate you!
- Color-Coded Characters: Green
- Heir Club for Men: A major reason Henry turned against her was that though she bore him a daughter, she failed to give him a son.
- Hidden Depths: After coming off as The Ditz for most of the show, she presents a very erudite critique about the flaws of comparing the six women. Though it's suggested at the end that her ditziness may have been at least partly an act.
- Phoneaholic Teenager: To the point she misses her cue the first time!
- Gratuitous French: Justified like Catherine of Aragon and Anne of Cleves in that she grew up in France.
- Suddenly SHOUTING!: "OH MY GOD YOU GUYS HE'S REALLY GONNA CHOP MY HEAD OFF!"
- Sympathetic Adulterer: Admits she flirted with some men (and perhaps went further) when Henry began sleeping around, "just to make him jel." She's still portrayed sympathetically, mostly because Henry responded by killing her.
- Color-Coded Characters:Gray/White
- Death by Childbirth: Of Edward VI. Although he outlived both of his parents.
- Hair of Gold, Heart of Gold: Often played by a blonde, she is perhaps the kindest of the queens, only losing her temper once.
- Pungeon Master: "suddenly see more note and "the Royal-ling Stones" note
- Silk Hiding Steel: "Heart of Stone" is all about this trope, with Jane singing that no matter what comes her way, no matter what Henry puts her through, she can take it, and is still going to be standing in the end.
- Team Mom: Shares this role with Parr, given as she only loses her cool ONCE in the whole musical, and is generally one of the calmer queens.
- Born Lucky: Anne, out of all the others, got the best deal: divorced from Henry and a large settlement to boot.
- Color-Coded Characters: Red
- Fan-Preferred Couple: With Katherine Howard, as the actresses who portrayed them in the original London cast are a couple.
- Graceful Loser: The other queens are quick to point out that Anna's entire would-be argument that she had the worst time of being married to Henry consisted of bragging about how great her independent, single life was as his honorary "sister." She quickly concedes and shrugs it off with a cheerful (and still slyly boastful) "Oh, well. Back to the palace!"
- Gratuitous German: Like Anne Boleyn and Catherine of Aragon and their native languages. Anne is from Germany, so it's logical she'd speak it.
- Hollywood Homely: Henry dismissed her claiming her looks weren't up to scratch, but her actresses are usually fairly attractive. Though Cleves doesn't accept his assessment.
- Troll: "Guys, I have the Plague!"Other Queens: "WHAT?!"Anne: "LOL, just kidding. My life's amazing!"
- Am I Just a Toy to You?: She has a Heel Realization about the men who abused her when she was younger, realizing that none of them cared about her in the end.
- Break the Cutie: We see this happening to her in the course of her song.
- Color-Coded Characters: Pink
- Deadpan Snarker: "Globally revered/Although you wouldn't know it from the look of that beard"
- Despair Event Horizon: "I thought it would be different, but it's NEVER, EVER DIFFERENT!"
- Fan-Preferred Couple: With Anne of Cleves, due to the actresses from the original London cast becoming a couple.
- Fille Fatale: Deconstructed and played for tragedy. For all her promiscuity and flirtatiousness, at the end of the day Katherine is a teenage girl who adult men use as a sex object.
- Sanity Slippage Song: Despite how many have interpreted it, throughout "All you wanna do" Katherine slowly goes insane with pain and grief.
- So Beautiful, It's a Curse: At first she's rather arrogant about her beauty and claims that she's the best-looking of the monarch's many lovers ("I think we can all agree/I'm a ten amongst these threes"). But then she starts going into her past"And ever since I was a child/I'd make the boys go wild"and explains that throughout her entire life, men have treated her like a sex object (in Real Life, for example, Katherine was only thirteen when her music teacher, Henry Mannix, began having sex with herand he was thirty-two). Though initially Katherine claims that she likes all of the attention and power she derives from these relationships, she ultimately realizes that she's been a victim of statuatory rape and abuse for her entire life, and the one time she thought she'd finally made a male friend, it turns out he was in love with her too; to rub salt into the wound, it was her friendship with that man which ended up getting her killed, as she was accused of adultery.
- Sympathetic Adulterer: Justified because what happened with Culpepper was unambiguously rape in the musical. (Historically, whether or not their encounter even took place is unknown.)
- The Woobie: And how. As much as the other Queens (except Cleves) have their moments, Katherine was sexually abused by all of the important men in her life, save her father, before being executed for having an affair.
- Brainy Brunette: Frequently played by dark-haired performers, Parr is a published author (in Real Life she was the first Queen Consort to produce a book under her own name) and an advocate for female literacy.
- Color-Coded Characters: Blue
- "Dear John" Letter: Her song describes the letter she had to write to her sweetheart after Henry proposed.
- Team Mom. If Jane isn't, she is. She's the sole one who doesn't get caught up in the fight (despite insults flung her way) and indeed, in Six she's the one who organized the whole thing.
- True Blue Femininity: Dresses in blue, and is kind and even-tempered even when she is being insulted.
- Abhorrent Admirer: To Parr, who was in love with another man at the time Henry proposed.
- The Bluebeard: Killed two of his wives (Boleyn and Howard) on trumped-up charges, arranged for another (Aragon) to die of neglect.
- The Ghost: Does not appear in the play, but is portrayed through his effect on the characters' lives.
- He does appear on-stage in the West End production. He's the vacuum cleaner they clean up the show with.
- Hate Sink: The entire musical is his ex-wives pointing out how he ruined their lives. (Only Seymour defends him, but even she realizes his love for her was conditional, on her having a son.) And between them he had:
- A messy beard
- A Teeny Weenie and impotence
- A complete inability to keep it in his pants
- Gross obesity
- Leg ulcers
- Heir Club for Men: A major motivator for his serial matrimony.
- Large and in Charge
- Karma Houdini: Died of natural causes, still rich, powerful, and respected.
- Start My Own: When Rome wouldn't give Henry an annulment from Aragon, he decided to break away and found his own church.
