Affably Evil: Prime Minister Drummond in the second volume, who's a rather affable chap even after it's revealed he conspired with Woolf to kill off all of the other resistance leaders at the Brick Lane Massacre, claiming I Did What I Had to Do
Alternate History: The setting is Britain that had lost the Napoleonic War 200 years ago, and the royal family were executed. It had then been part of the French empire until twenty-three years previous when it was begrudgingly given independence after a prolonged campaign of civil disobedience and anarchist bombings. Now it's called The Socialist Republic of Britain, a small and unimportant country connected to the French Empire by the Channel railway bridge.
They were wrong though, that it was actually the Knights of the Lion, with the lion being Emperor Napoleon XII. In fact, the Knights of the Lion equates to The Omniscient Council of Vagueness: weapons dealer and newspaper owner Madame Krupp, The Prime Minister Jean-Marie Lapine, Reinhardt the Minister of War, the Archbishop of Paris, and Hyen the Chief of Police.
Bulletproof Vest: LeBrock wears one under his waistcoat, though it looks to be like some sort of super-strong chainmail.
Carnivore Confusion: There's a scene involving LeBrock asking for a full English breakfast, which included meat. This is weird as there are, in fact, non-carnivorous anthropomorphic characters. See also Furry Confusion.
Cultured Badass: Detective Ratzi. He may look like a pampered gentleman, what with the monocle and bow-tie, but he can kick ass.
Dirty Communists: Averted as a whole. "The Socialist Republic of Britain" shows nearly nothing that we associate with Communism or Socialism other than a brief, sarcastic mention of being a "classless society". It almost comes off as Informed Socialism.
The French Revolutionary Council is closer to actual socialism. According to the industrialists meeting at Toad Hall in "Bęte Noire" the Council's policies include wide ranging nationalizations and universal healthcare and education.
We are told that the enemy in French Indo-China are the "Communards," however
For those who haven't read the first book, much of the story is a metaphor for The War on Terror.
There are even protesters that are against the French war in Indo-China rallying in the streets of Paris!
This applies pretty much to the entirety of the whole book really.
Fantastic Racism: The anthro characters aren't too fond of the humans, calling them with racist terms (see Fantastic Slurs below) and giving them menial tasks. According to LeBrock, they've not made it to Britain because they weren't allowed passports, as they were not granted citizens' rights.
The Archbishop in the first book expresses disgust at interspecies mating. It is uncertain if that is because he believes in the separation of races (akin to prejudice against mixed relationships) or simply because he sees it as a sign of general deviancy. No other signs of segregation among animals was shown.
In the second book, a badger prostitute attempts to proposition two ducks, who turn her down because she "isn't even waterfowl."
Heroic BSOD: LeBrock undergoes one at the beginning of Grandville Mon Amour, following the death of Sarah.
Humanoid Female Animal: Surprisingly averted, as the male and female animal people have the same level of anthropomorphism.
Though most of the female animals have human-style head hair, which all but two males animals lack...and those are a lion (his mane) and a hyena (who may have just slicked down his fur, from the looks of things).
Permanent Elected Official: The founder of the Socialist Republic of Britain and it's first Prime Minister is due to become this during the second book. Despite his respect for the Prime Minister, LeBrock disapproves the move, believing that it is the first step to becoming a People's Republic of Tyranny. In the end, he doesn't make it, having been revealed to have collaborated with Britain's former French military governor to massacre all of the other resistance leaders, and subsequently thrown off a building by Le Brock.
Petting Zoo People: Moreso even than usual, as the "animals" turn out to have animal heads on 100% human, furless, tail-less bodies. They occasionally do their bestial reactions, but generally they belong to this category.
La Résistance: The English Resistance came in bothvarieties. There was the more mainstream anarchist/socialist forces (of which both Le Brock and his father were members), and then there were the Angry Brigade, who were vicious anti-French terrorists. Both sides have a notable distaste for each other
Shirtless Scene: LeBrock hides in a steam bath, going nude with only a towel covering him. Also with Coco.
The second volume gives us Miss Piggy as a French prostitute, as well as Donald Duck as a pervert who wrongly confessed to the murder of the prostitutes, and French comic book character Gaston Lagaffe as a street tough who tries to mug Ratzi.
Prime Minister Drummond, who is a bulldog, is probably a reference to the "Bulldog" Drummond series of detective stories.
Species Surname: Very common, though some are subtler than others. French Prime Minister Lapine has the bonus of having a name that relates to rabbits (which he is) and the French nationalist politician Jean-Marie Le Pen (which Lapine also is).
Starving Artist: The Artists at "The Agile Rabbit" in "Bęte Noire" lament about being this. It's soon revealed that they are merely without comissions at the moment, hinting that they're not as badly off as they like to portray themselves being.
Torture Always Works: Or at least usually works. Archie tortures everyone he captures in Book 1, and gets results based on how much they know. If they know a lot he gets complete, accurate information in minutes.
Translation Convention: As France had ruled England for a few hundred years in the history of this world, every character is actually speaking French (which leads to some French idioms being directly translated to English). Early on the first book Ratzi asks what the weird language some country folk are speaking in, only to be told they're speaking English.
What Happened to the Mouse?: It receives a passing mention but otherwise, there is very little in the second book to indicate that mere three weeks ago France suffered a revolution after the French Emperor and his Government were practically wiped out in a bloody attack.
