- Complete Monster: Jenna Zan Arbor, fascinated by the Force, Jenna first appeared in Jedi Apprentice, where she captured, tortured, and killed in an effort to work out how their abilities operated. Found out and pursued by the Jedi, she fled to the planet of Belasco, where she infected their water supply with a bacterium that would kill millions unless she was paid to "discover" the cure. Arrested and imprisoned, Jenna escaped custody in Jedi Quest, and, allying herself with gangster and terrorist Granta Omega, set herself up as a drug dealer before joining his effort to poison the entire Galactic Senate. When Omega died, Jenna joined the Separatists, manufacturing chemical weapons—including the gas that Durge used on Naboo's moon—for them, before changing her allegiance to the Empire at the end of the war. At the time of her eventual execution by Darth Vader, Jenna was part of the Death Star project, and was engaged in experiments in mind and memory manipulation. Void of ethics, and interested only in profit and fame, Jenna Zan Arbor was prepared to do anything, however depraved, to satisfy her curiosity.
- Moment of Awesome: Qui-Gon tames a draigon and rides it just by thinking hard at it.
- Faux Symbolism: Guerra and Paxxi's names. No, one is not warlike and the other a pacifist, nor do they have any kind of rivalry or otherwise opposing personalities. They both act like Loveable Rogues, in fact.
- Harsher in Hindsight: Qui-Gon's wistful reaction to Anakin's belief no one can kill a Jedi was already sad but here we see him lose numerous loved ones during his earlier years. It's hard not to imagine he was thinking of Tahl or Xanatos when he said that.
- Hilarious in Hindsight: Siri Tachi's name became a bit funny after Apple named the iPhone's personal assistant program "Siri". And with Microsoft calling their Windows Phone's personal assistant program "Cortana", we now have two talking smartphone applications named after science-fiction characters.
- Memetic Mutation: A meme is frequently passed around of an anguished looking Obi-Wan taken from Revenge of the Sith with the caption "Bought an iPhone just so he could talk to Siri again."
- Informed Wrongness: Pretty much every mention of the Melida/Daan incident and Obi-Wan leaving the Jedi to help them afterward is portrayed as the wrong choice for Obi-Wan to have made in both Jedi Apprentice and Jedi Quest, despite the fact that his intervention greatly helped put an end to a planet wide centuries long war and the fact that Qui-Gon all but forced him to leave by putting him in one hell of a Sadistic Choice.
- Magnificent Bastard: Xanatos comes close at times, though he fails in the end. The stunt he pulls in Day Of Reckoning in which he sets up a lottery to distract the citizens of Telos from his mining operations, then uses said profits to pay for the mining is a thing of beauty. In effect, he gets the Telosians to pay for the destruction of their own planet, while keeping them pacified with Bread and Circuses, and remaining the most respected man on Telos. And then there's his attempt at blowing up the Jedi Temple and stealing the treasury. His only problem is his inability to cope when his plans go badly. This ultimately leads to his death in Day Of Reckoning.
- Uncanny Valley: Happens on the book covers more than once, thanks to wonky CG alterations of Ewan McGregor's face to appear younger. Paradoxically, he sometimes gains wrinkles in this process◊.
YMMV / Jedi Apprentice
