People write the most special things.. XD
About the Bartimaeus trilogy:
(notice the alphabetical order? :D)
Adults Are Useless: Not all of them, admittedly, but the Big Bads are all defeated with the brains of a kid or a couple of kids, the mentors are all fairweatherand the commoner adults are generally sheep. This may be somewhat of an overstatement, though, as most of the plotting and trickery is pulled off by a djinni who is thousands of years old. Additionally, many adult commoners secretly resist the government in later novels.
Played mostly straight, with magicians, at Lovelace's party.
Nathaniel, at his high points.
Bartimaeus and Kitty too. (Yes, Kitty has noble intentions, but do remember that she's a terrorist.) So, everyone.
Badass Boast: Bartimaeus, constantly. For example: "I am Bartimaeus of Uruk! I am Sakhr al-Jinni, N'gorso the Mighty and the Serpent of Silver Plumes! I have rebuilt the walls of Uruk, Karnak and Prague. I have spoken with Solomon. I have run with the buffalo fathers of the plains. I have watched over Old Zimbabwe till the stones fell and the jackals fed on its people. I am Bartimaeus!" However, it's just as likely to be subverted when the subject either doesn't recognize him or is simply unimpressed.
"You rebuilt the walls of Prague? What, the ones that took Gladstone ten seconds to break through? Sure you didn't work on Jericho too?"
"Yes, but he doesn't like to talk about it—"
Big Brother Is Watching: The vigilance spheres used throughout the series.
The Brute: Jabor all the way.
Cassandra Truth: Faquarl when he says it's possible for the spirits to start a revolution (though it fails, he still started one). Also, Nathaniel's theories are never believed until it's almost too late.
Chef of Iron: Farqual's preferred form is a jovial chef - Bartimaeus notes that he's been hanging around in kitchens for a few thousand years. This also makes him an Evil Chef.
Curb-Stomp Battle: Faquarl vs. four djinn sent to capture him. (More precisely, they were sent to capture the person whose body he was residing in, and so didn't really see that coming.)
Honorius vs. The Resistance.
Faquarl and Jabor serve this role to Simon Lovelace in the first book.
Faquarl in the third book serves as this to Makepeace (in his disguise as Hopkins) and later, Nouda. Of course, he's actually weaker than Nouda, since Nouda is a force of nature((.Dragon with an Agenda: Faquarl. He engineers, by out-Chessmaster-ing Makepeace, a chance for spirits to rebel against and take revenge on humanity.))
Double Entendre: In this scene.
Nathaniel: I tried last night and you were gone. Who was it? Which magician were you seeing?
Bartimaeus: Don’t get so worked up. It was a brief encounter. Nothing serious. It’s over.
Nathaniel: Nothing serious? Think I’m going to believe that?
Bartimaeus: Calm down, Mr. Jealous. You’re making a scene.
Nathaniel: Who was it? Man or woman?
Bartimaeus: Look, I know what you’re thinking, and I didn’t.
Eldritch Abomination The spirits on the higher planes, Faquarl especially. His true form (which is never described besides having tentacles) makes even other demons queasy and he even killed some ravens when he appeared to them in that form. Furthermore, Ramuthra and later Nouda appear as, respectively, a disturbance on all seven planes, only visible because he's the only area that isn't being ripped at the seams and, after inhabiting a normal human body, a mass of inhuman tentacles: barbs, horns, you name it
Enemy Mine: Bartimaeus and Faquarl in the prequel, due to sharing the same master (and equally loathing said master)
Faquarl is this to Bartimaeus. Both are djinn of considerable power and cunning and resent the spirits' slavery by magicians. However, while Faquarl sets off a violent spirit rebellion against humanity, Bartimaeus, through interactions with people such as Ptolemy, Kitty, and Nathaniel, starts to believe that both people and spirits can change for the better and ends up saving humanity.
Simon Lovelace is what Nathaniel could have become if he allowed his ambition to consume him. In the later books, Nathaniel at the lower points of his Character Development starts to resemble Simon Lovelace, which Bartimaeus points out.
Expository Hairstylechange: Nathaniel's haircut between books two and three underscores the changes in his personality.
Failure Knight: We learn in book three that Bartimaeus feels this way about Ptolemy.
Footnote Fever: Bartimaeus's sections are littered with it.
Humans Are Bastards: Bartimaeus certainly thinks so, while Nathaniel thinks djinn are Always Chaotic Evil. The ultimate conclusion seems to be that neither species is inherently better or worse.
Idiot Ball: For all his intelligence, Bartimaeus gets this on occasion. For example, accidentally leading Lovelace to Underwood's house in the first book, and turning off the lights when faced with Faquarl in the third book (even though spirits can see perfectly well in the dark).
Interspecies Romance: Parodied and ridiculed, not that it stops the Shippers. Also, while it may not qualify as romance per se, Succubi exist and are at times summoned. In The Ring of Solomon, the Big Bad and his shadow.
Our Genies Are Different: They're demons.
On the contrary! "Demon" is a highly offensive and pejorative term. They're exalted spirits!
Our Werewolves Are Different: They're police officers.
if only there was an 'our police officers are different' trope.
Reverse Psychology: Bartimaeus "praises" Kitty for her "intelligence" in leaving Nathaniel to his doom. He also uses this to trick a trapped marid into revealing the secrets of Solomon's Ring, and to manipulate several of his previous masters to their deaths and...yeah, he does this a lot.
The Rival: Faquarl -> Bartimaeus; Jane Farrar -> Nathaniel.
Shapeshifter Default Form: Bartimaeus has a plethora of guises at hand, but in the trilogy he is known to be most comfortable in the appearance of Ptolemy. Faquarl similarly defaults to the appearance of a pudgy chef with a meat cleaver.
Shut Up, Hannibal!: In the third book, when Faquarl accuses Bartimaeus of betraying his kind, Bartimaeus angrily retorts that Faquarl is the traitor who abandoned the Other Place (where they and other spirits come from) and even encouraged other spirits to leave for the sake of vengeance.
Volleying Insults: Bartimaeus and Nathaniel at their most childish - i.e. most of the time.
Weak, but Skilled: Bartimaeus, relatively. Djinn are in the middle in the hirearchy of conventional, commonly summoned demons (behind afrits and marids). He's a moderately strong djinni, but is weaker than Faquarl and Jabor in an all-out fight, not to mention anything stronger. He gets by with his wits and running away at appropriate times, especially as he grows progressively less strong in Book 3 from being continually summoned. As djinn are the most powerful demon likely to be summoned, with afrits and marids being a sign of Oh Crap levels of power, he's often moderately outclassed.
White-Haired Pretty Boy: None of Faquarl's forms are desribed as having white hair, but he has the personality down pat.
