HERE BE UNMARKED SPOILERS. BEWARE!
All canon tropes up to The Phantom Menace apply unless otherwise noted.
Jedi
Obi-Wan Kenobi
- The Ace: All-round excellent at everything (except obeying orders).
- Adaptational Badass: While canon Obi-Wan was impressive enough by himself, this one's a One-Man Army and absolute Master Swordsman by his early twenties.
- Affectionate Nickname: Qui-Gon likes to call him "brat." Siri occasionally calls him ben'ke, which is Twi'leki, though never translated.
- Amazon Chaser: Though he'd never admit it, Siri's combat skill in the dojo turns him on a bit.
- Badass Bookworm: Loves his history and philosophy, a high-ranking student, and an expert combatant.
- Berserk Button: As a young man, someone else insulting Qui-Gon could get a rise out of him like almost nothing else could.
- Big Brother Instinct: Has this towards Bant.
- Big Eater: As a teenager, he believes in moderation in all things. So he makes sure to eat moderately...which is to say, a little of everything.
- Blood Knight: Downplayed. While he doesn't enjoy combat, as such, he loves sparring.
- Character Development: Goes from a naieve, though snarky, boy to a great Jedi Knight.
- Deadpan Snarker: Possibly the snarkiest character in the entire series. Which is saying something.
- Exact Words: Loves using this, such as in Lineage I, when he promises Qui-Gon that he "won't stop him from doing what he needs to do."
- The Gadfly: He can veer into this territory with friends, such as Garen, Siri, Bant, and, occasionally, Qui-Gon.
- Good Is Not Soft: Especially after his tutelage from Dooku. Obi-Wan is quite kind, but he is definitely not to be messed with.
- Good Is Old-Fashioned: Very big on tradition, which occasionally gets him into arguments with Qui-Gon.
- The Hero: The main character of all of the stories.
- Heroic Self-Deprecation: Has a fairly low sense of self-esteem.
- Innocently Insensitive: Obi-Wan has his moments, usually when dealing with non-Jedi.
- During Lineage VII, he makes a few mistakes when helping Siri which clearly upset her, such as trying to grapple her. It wouldn't be such a big deal if she hadn't been raped.
- Master Swordsman: As well as his expertise in Ataru, he's got Makashi, Jar'Kai, and "informal zombie-slaying" techniques under his belt.
- The Mentor: Plays this to Zhoa and to Anakin.
- One-Man Army: Capable of carving through enemies like a lightsaber through butter. See Legacy, where he defeats a dozen tanks single-handed, or Lineage XI, which has him demonstrate what even Mace Windu calls "impressive zombie-slaying techniques."
- Sarcastic Devotee: He would follow Qui-Gon off a cliff. And spend the entire way down complaining.
- Socially Awkward Hero: Zig-zagged as a young man. While he's a polished diplomat, his misunderstandings of common non-Jedi life customs can make him this.
- UST: Has loads of this with Siri Tachi. It's eventually resolved (sort of), and they move into Star-Crossed Lovers territory.
- Vitriolic Best Buds: Constantly involved in snarking matches with Garen, Feld, and Siri, but cares deeply for them as well.
Qui-Gon Jinn
- Ambadassador: An expert diplomat and Master Swordsman. He passes both these traits on to Obi-Wan.
- Berserk Button: Anyone attempting to harm Obi-Wan (see Papa Wolf).
- Bunny-Ears Lawyer: The Order's resident maverick, but also highly respected.
- Deadpan Snarker: One thing he very clearly passed on to Obi-Wan.
- Heartbroken Badass: Became this after Xanatos fell to the Dark Side, and again after Tahl dies.
- Hypocritical Humor: Proud as punch whenever Obi-Wan follows the Living Force and disobeys orders... but irritated when it's his orders that get disobeyed.
- The Last DJ: He could easily have been on the Council if he didn't keep "following the Living Force."
- Martial Pacifist: Doesn't enjoy fighting, but if you push him, he will prove that he's not to be trifled with.
- Master Swordsman: It's very clear where Obi-Wan got it from, and though he and Dooku have a rough relationship, it's clear where he got it from, too.
- The Mentor: Played this to Feemor (though in that case it was more of a Big Brother Mentor), Xanatos, and Obi-Wan.
- Offscreen Moment of Awesome: He and Tahl arranged the New Apsolon dispute long before Obi-Wan was born.
- Papa Wolf: Do not hurt Obi-Wan. At all. Ever."Sifo-Dyas can take a meditative retreat in the lowest Sith hell before I permit him to so much as touch my apprentice again."
- Psychologist Teacher: Often plays this role in relation to Obi-Wan.
- Rage Against the Mentor: Qui-Gon and Dooku did not exactly have a warm, loving relationship.
- Screw the Rules, I'm Doing What's Right!: Always.
- Vitriolic Best Buds: Has this with Tahl before it moves into UST, and shares traces of this with Mace.
Yan Dooku
- Chessmaster: Plays dejarik and is an absolute Manipulative Bastard (see below).
- Cultured Badass: Drinks tea, enjoys philosophy and history, and is a master of what he calls the most "disciplined" lightsaber form.
- Deadpan Snarker: Has a very, very dry wit.
- Good is Not Nice: Dooku has his compassionate moments. Just not very many.
- Knight Templar: He will stop at nothing to defeat the Darkness.
- Master Swordsman: One of the best in the Order, which is saying something.
- Manipulative Bastard: There are many examples, but one of the most chilling is in Legacy V, when he used torture to cover slipping a tracking device into Darth Maul's body, then let him escape from the Temple, killing two Knights along the way, to trace him back to Sidious.
- The Mentor: Taught Qui-Gon and Obi-Wan for a while.
- Mind Probe: Capable of doing this with Telepathy. It's nasty.
- Offscreen Moment of Awesome: He's been fighting the Dark Side for a very long time, and done and seen plenty of things.
- Pet the Dog: Occasionally has a moment of kindness towards Obi-Wan, such as comforting him after Qui-Gon's joining the Whills. It's clear that, despite his impeccably stoic demeanor, he really does care about the young man. In his own way.
- Pride: His greatest flaw, which Yoda calls him out on.
Siri Tachi
- Action Girl: She kicks butt with the best of them.
- Affectionate Nickname: Adi calls her "siripasa."
- Deadpan Snarker: Gives as good as she gets when engaged in Snark-to-Snark Combat.
- Hair of Gold, Heart of Gold: She's much more of a Jerk with a Heart of Gold than most examples of this trope, but the heart of gold is still there.
- Hot-Blooded: She can get very riled up. Especially by Obi-Wan.
- Jerk with a Heart of Gold: Though she can be very spiky, she's also undoubtedly and unreservedly compassionate.
- Master Swordsman: Gender-inverted; she can give Obi-Wan a serious run for his credits in the dojo, though she's not quite on his level.
- Star-Crossed Lovers: With Obi-Wan.
Mace Windu
- Deadpan Snarker: Has his moments, usually at Qui-Gon's expense.
- Hidden Depths: Much kinder than his intimidating mien might suggest.
- Master Swordsman: He invented his own, incredibly lethal form, and is on par with Dooku.
- The Mentor: Informally, to Obi-Wan.
- Reasonable Authority Figure: Usually tempers punishment with understanding.
- Vitriolic Best Buds: With Qui-Gon, and with more emphasis on the vitriolic, Dooku.
Yoda
- Eccentric Mentor: Sometimes, he'll be your best friend, and sometimes, an incredibly strict taskmaster.
- Master Swordsman: Kick your butt in the dojo, he will.
- The Mentor: He's been this for every single Jedi at some point, and usually remains as this when they need him.
- Pint-Sized Powerhouse: Size matters not, indeed.
- Psychologist Teacher: A very wise teacher who will tailor his lessons to suit his audience.
- Putting the "Pal" in Principal: A very kind and understanding mentor to every Jedi.
- Reasonable Authority Figure: To his subordinate Jedi, not expecting any more or less than their very best.
- Stern Teacher: As noted above, he doesn't expect any more than the best his students can give... but he won't accept any less, either.
Tahl
- Face Death with Dignity: Even at the end, she remains calm and dignified.
- Parental Substitute: Obi-Wan all but acknowledges outright that she's the maternal figure he never had.
- Star-Crossed Lovers: With Qui-Gon
Antagonists
Xanatos DuCrion
- The Ace: Said to have been a star pupil before his Fall.
- A Pupil of Mine Until He Turned to Evil: Qui-Gon's, and boy is he touchy about it.
- Better to Die than Be Killed: As per canon, hurls himself into a pool of acid rather than be captured.
- Dark Is Evil: Dark hair, dark eyes, dark robes, and a black heart.
- Evil Is Petty: Emotionally abuses Obi-Wan just to get back at Qui-Gon and the Jedi.
- Evil Mentor: Wants to be this for Obi-Wan.
- Faux Affably Evil: He pretends to be polite to others, but he just wants revenge against Qui-Gon and the Order.
- Rage Against the Mentor: Whatever problems Qui-Gon has with Dooku, they are nothing compared to Xanatos' with Qui-Gon.
- Revenge: Intends it against the Jedi.
- Starter Villain: The Big Bad of Books 1 and 2.
- Villain with Good Publicity: As head of Offworld, he is this.
- You Killed My Father: Blames Qui-Gon for this.
Sifo-Dyas
- Birds of a Feather: Many of the tropes in his folder could also apply to Dooku.
- The Chessmaster: Quite a good one, though see Out-Gambitted below.
- Deadpan Snarker: Has a very dry wit, which he wields at the Jedi's expense.
- Evil Former Friend: To Dooku.
- Good is Not Nice: What he originally comes across as-and what he once was.
- He Who Fights Monsters: Dooku says that this happened to him.
- The Man Behind the Man: For the antagonists of Books 5,6, and 7. It's hinted that Sidious might be this to him.
- The Mentor: To Jedi Knight Chiros, a fellow Sentinel.
- Mind Rape: Very good at this.
- Out-Gambitted: He's a very good Chessmaster-unfortunately for him, Dooku is better.
- Smug Snake: Thinks that he's even better than he actually is. This proves to be his undoing.
- Walking Spoiler: His Fall is a big plot element in later books.
Darth Maul
- The Apprentice: To Sidious.
- Foil: In-universe. He and Obi-Wan see each other as this.
- Hot-Blooded: Actually becomes something of a plot point: One thing which reassures Obi-Wan is that he's not fighting a Dark Lord of the Sith, but rather a young buck like him.
- Late-Arrival Spoiler: Doesn't appear until the very end of Book 9, and isn't seen until the following book. Nevertheless, he makes quite an impact.
- Living Weapon: Forged into one by Darth Sidious.
- Master Swordsman: Anyone who can go toe-to-toe with Adaptational Badass Obi-Wan is definitely this.
- The Quiet One: As per canon, he doesn't have much to say, but that doesn't make him stupid or any less dangerous.
- Red and Black and Evil All Over: As per canon.
