Lanfeust de Troy is a French heroic-fantasy comic series by Arleston and Tarquin, published by Soleil Productions. It features the eponymous hero Lanfeust in the world of Troy, and his efforts to save said world from total dominion by an evil army. The main feature of this series is that each inhabitant has a single magical power, be it useful or useless (melting metal, boiling/freezing water, teleporting, farting from the ears...), but sometimes, one person can have the ultimate power, that consists of every single power ever. This is the case for Lanfeust, a young blacksmith who, while mending the sword of a passing aristocrat, discovers that touching the sword's pommel grants him the ultimate power.The series has also been Recycled IN SPACE! (Lanfeust des Étoiles), rewritten as a manga (Lanfeust Quest), and as Spinoff Babies (Gnomes de Troy). And recently, given a sequel, in the form of Lanfeust Odyssey... Annnnnnnd another series has just come out: Cixi de Troy. This one focuses on Cixi from when she leaves the main band to when we meet with her again. There is also a prequel series of sorts, involving the adventures of Hebus's grandfather Tetram, his adoptive human daughter Waha, and her would-be boyfriend Profy (Trolls de Troy).
Lanfeust provides examples of the following tropes:
All Trolls Are Different: Huge, anthropophagist, fur-covered humanoids with Super Strength and a violent aversion to water. (It might make them clean and thus alienate their flies.) They can be enchanted by a sage, turning them into obedient servants, but DON'T let them get drunk. Trolls actually developed a highly advanced culture built around Heroic sociopathy: they can perfectly function in civilized human society, but unless they take a fancy to some of the locals, they may kill people at random to pass time.
Big Bad: Baron Averroes, who then turns out to be Thanos.
Big Eater: The trolls. Trolls will eat anything that moves and drink everything that doesn't. It's not that they're evil, they're just very hungry. At one point, it is said they can eat or drink anything except water (it might make them CLEAN!). When a troll tries to eat something and it doesn't get digested properly it's a major plot point.
Charm Person: A common spell used to make trolls very strong servants. Problem is, it doesn't stand up to alcohol. There's a stronger enchantment that can hold even if the troll drowns himself in booze, but by strongly diminishing their savagery, which weakens them. Granted, considering what trolls are, most of the time, it's not a problem.
Early-Installment Weirdness: Thanos doesn't appear at all in the first album. The only antagonists are random brigands. Also, Cixi was more immature.
Even Evil Has Standards: When Venerable Fuquatou discovers that the courtesan blackmailing him is looking for the mutant siren "sisters" of Waha in order to use them in her brothels, he kicks her out of the dragon they're flying on.
Everyone Is a Super: It's close to Xanth in comic form. Everyone on the world of Troy has the potential for magic power, enabled by people who train as sages at a Wizarding School. Sages learn some charms and spells at school and "turn off" their own powers to allow people within a certain range to use theirs. They are valuable resources; for example, when trolls attack caravans, they often focus on the sages. There are also a few nations with cultural differences in how magic manifests.
The Baronies are opposed to magic for culturalreasons and don't allow sages among them. It's unclear whether people from there would discover their individual talents if they spent enough time in foreign lands, or whether people born there can't have magic powers at all, or what.
Everything Trying to Kill You: Troy's wildlife is incredibly diverse and inventive in the ways it tries to eat you. And let's not go into the trolls...
Eye Scream: Thanos puts out Lanfeust's eyes (with an ivory blade, when he melts the metal one).
A God Am I: How Thanos reacts to the ultimate power.
Godiva Hair: Described as a "genetic trait" of mermaids in Trolls de Troy, and even applies if they're turned upside-down.
Gods Need Prayer Badly: The Darshanide Gods need believers to exist. The first time the heroes visit the divine court, they witness the goddess Lynrenö fading into nothingness as her last believer dies.
Happy Rain: "There it is, your ET shower!" (though the pun unfortunately doesn't work in English).
Hates Baths: All trolls. They hate to take baths, but love to drink bathwater: as Hebus explains when he drinks C'ian and Cixi's bathwater, "It's like stew: when you're not allowed to eat the meat, you can still drink the broth."
Identical Grandson: Or identical niece. Cian's daughter, Cixi, shares her aunt's name, appearance and personality.
Another example, from the prequel series: Pröfy is actually half-troll. His mother, a full troll, once caught a human nobleman but felt more lusty than hungry at the time... Several days later, the man eventually escaped with his life. And several broken bones. And no clothes whatsoever.
"We rob'em, burn'em and rape'em, right cap'n?" "Noooo, that's what you did last time!" "Oh yeah, that wasn't much fun, especially towards the end."
Katanas Are Just Better: After he loses his sword, Lanfeust forges himself a new one and gives it the shape of a katana. Granted, at the time they're in the knockoff of China/Japan/Every Asian country related trope you can think of. Subverted when he sees the katanas forged by the personal smith of the emperor: he describes them as "cute toys", breaks in half one of the very obviously expensive swords in front of the shocked shop clerk, before forging an Eckmülian longsword for himself which only looks superficially like a Darshanide blade.
MacGuffin: The fragment of the Magohamoth's horn. It gives Lanfeust and Thanos the ultimate power.
Also, Ci'an and Cixi are the names of the last two Dowager Empresses of China. And Cixi's name definitely sounds like her greatest attribute.
Mundane Utility: Depending on the power you get, it pretty much determines your job. Lanfeust, who can melt metal, is a blacksmith, one girl whose power is to make people thirsty works in a tavern.
Our Dragons Are Different: Used as mounts, they come in various shapes and forms, some being individual mounts and other being large enough to serve as airplanes.
Pandaing To The Audience: Darshanide trolls (white-furred, with black spots over the eyes), which are a subversion of how this trope usually works, because they're at least as savage and brutal as regular trolls, although they are smaller.
Every troll's name is such that, if you add "troll" to the front or end, you get a word or phrase; Hébus gives Trolleybus, Haïgwépa for Highway Patrol. Some other characters, like the Darshanide ambassador, also count, but it's hard to figure out.
The Big Bad of Lanfeust des Etoiles is named after the mascot of a cookie brand.
In Lanfeust Odyssey, a possessed Lanfeust kills Nicolede in full view of everyone in Eckmul.
Before that, in Lanfeust of the stars, Lanfeust and Swiip end up eighteen years in the future. It is never fixed, meaning Lanfeust has now the same age as his son, leading Cixi to eventually break up with him since she's spent the years making a name for herself in the future.
