Authority Equals Asskicking: You're the King/Queen of Albion, and nothing is capable of stopping you from cutting a bloody swath through hordes of enemies. Not even an Eldritch Abomination and all of his children.
Badass Abnormal: After receiving the Gauntlets that allow you to use magic.
Offhand Backhand: It is entirely possible to be kicking the crap out of the enemies in front of you with your melee weapon, then abruptly switch to your gun, fire off a shot over your shoulder to hit and kill the enemy running up behind you, and then continue to beat his buddies into submission.
Badass Beard: Male or female, feel free to sport one.
Lady of War: The female Hero can either play this straight or subvert it, depending on the player's style of combat. While you can certainly hurl your enemies about with magic and shoot them from afar, you can also bash their skulls in with a giant-ass hammer.
Badass Longcoat: There are a number of outfits that involve these.
Batman Can Breathe in Space: Wander through a Demon Door. Find yourself on a moon-like planet whose atmosphere changes with the press of a switch. Fail to die.
Be Careful What You Wish For: The Hero is definitely less than enthused by the realities of being King/Queen, judging by the way s/he slouches on the throne. The beginning of Traitor's Keep sees the Hero only being jerked out of his/her boredom with affairs of the state by an assassination attempt. Before that, s/he was falling asleep.
Improbable Aiming Skills: Anyone who can win a gunfight without even bothering to look at their targets most certainly qualifies.
Kicking Ass in All Her Finery: In The Masquerade quest, the female Hero is wearing a Pimped-Out Dress as she mows downs waves of enemies. And whether the Hero is male or female, you can feel free to kick ass in all kinds of fancy skirts and dresses.
Power Glows: If you use your magic enough, any tattoos you apply won't be black anymore. They'll be glowing bright blue.
The Quiet One: His/her dialogue is fully voiced, and this trope is well averted during the prologue, but for some reason the player character goes all quiet after that and very, very rarely speaks for the rest of the game.
Sexy Walk: When the Princess walks normally, she swivels her hips quite a bit.
Silent Protagonist: The first protagonist in Fable to completely avert this. He or she does not speak often, however, and still mostly makes odd grunting noises when preforming expressions.
Statuesque Stunner: The Princess, provided she's attractive, since she's taller than almost everyone else in the game.
Sword and Gun: If the player chooses; it could be Hammer and Gun.
You can also have other types of costume reference with some clothes and dye combinations.
Allies
Elise/Elliot
Absence Makes the Heart Go Yonder: Assuming they survive the first ten minutes of the game, in the short time you're gone, they meet and fall in love with the proprietor of a homeless shelter/orphanage because they believed you were never coming back.
Always Save theLove Interest: Can be subverted or played straight, depending on whether or not you choose to save Elise/Elliot or the protestors at the very beginning of the game.
Bad Dreams: If you marry Elise/Elliot, s/he will say that s/he still has nightmares about the last day in the castle, and believes s/he always will.
Damsel in Distress/Distressed Dude: At the very beginning of the game, her/his life is in your hands. If you choose to save her/him, you have to rescue her/him again later, when s/he is kidnapped by Nigel Ferret's gang.
Disposable Fiancé: Can be played straight or subverted. If you tell Elise/Elliot to come back to you, then they break up with Laszlo/Linda to marry you. If you stay silent or tell them to stay with Laszlo/Linda, they choose to get married to their current fiancé/e.
Green-Eyed Monster: Elliot shows hints of this if you marry him. Though, oddly, he does this if you give money to a beggar, yet not if you passionately kiss an unmarried lover in front of him.
Elliot: (to the Heroine) You're not putting what we have in jeopardy, are you?
Happily Married: With the Hero or with Laszlo/Linda, if they survive. However, if they decide to marry Laszlo/Linda, their dialogue before they leave strongly implies that they never quite got over you.
Inter-Class Romance: Subverted in that no one cares, but Elise/Elliot actually isn't a noble despite being close friends with and possibly the spouse of the prince/ss. The character description lists her/him as "Middle Class".
The One That Got Away: Implied to be their feelings toward you if you tell them to marry Laszlo/Linda.
Purely Aesthetic Gender: Save for a few sentences in the beginning, Elise and Elliot have identical dialogue.
Rapunzel Hair: Elise's hair is very long. And those curls bounce.
Red String of Fate: If you marry her/him, Elise/Elliot will occasionally make comments about how s/he thinks that s/he and the Hero were always meant to be together, and it was fate that brought them back together again.
Sadistic Choice: When the Hero confronts Logan about his intention to kill a group of protesters, Logan forces you to choose between Elise/Elliot and the protesters. This is one of the few choices which has no moral ramifications.
And just to drive the point home, Logan will have both the protesters and Elise/Elliot killed if you take too long to choose between them.
First Guy/Girl Wins: The above can be subverted if you tell Elise/Elliot to dump their fiancé/e and come back to you.
Satellite Love Interest: They're sympathetic to the plight of the people in Bowerstone and very fond of you, but other than that, there isn't much to their personality.
Stay in the Kitchen: Literally, you can find Elise in the kitchen if you marry her and after you move to the castle.
Of course, Elliot is always in the kitchen as well.
Survivor Guilt: If you choose to allow Logan to execute the protestors in exchange for sparing Elise/Elliot, s/he expresses guilt when you meet again over both the fact that s/he survived and the fact that s/he felt happy to know that s/he was going to survive, even through the horror of watching the protestors dragged away to be killed.
Claustrophobia: Walter suffers from this. It becomes a plot point later on when his debilitating fear leads him to become a target for The Crawler. It stems from being trapped inside a pitch black cave for three days with no hope of rescue in his youth.
Genre Blindness: Hey look, a swirling purple seal on a pit in the middle of an ominous cave surrounded by skeletons. I know! Let's pick up a book full of arcane symbols and read from it! Though, in his defence, there was no way either of them could have expected what they ran into in that cave. Plus it was kinda the only way out, so even if he did, he more or less didn't have a choice.
The Lancer: Although he doesn't particularly serve as your foil, he is your eternal sidekick and mentor.
If you're wondering exactly why, during the war, he and his unit sought shelter in a cave to hide from the enemy's army. The enemy did not follow them; they blasted the entrance, leaving him and his two surviving men trapped in absolute darkness for three days without food or hope of rescue.
Non-Action Guy: He cowers (very gracefully, Walter adds) in the one instance you see him in battle, and keeps well away safe in the Sanctuary as soon as he arrives.
Servile Snarker: Very politely, but still, he'll make his opinion of silly choices on clothing or hair known.
Undying Loyalty: "You currently have the support of two friends. Jasper, who will serve you forever..."
Sabine is the King of Mist Peak and leader of the Mountain Dwellers. He is the first ally that the Hero recuits to overthrow Logan, on the condition that the Hero restore the mountains to him and his people.
"We're going to show Logan just what traitors can do."
Ben is Major Swift's second-in-command and member of the military Old Guard. He is a friend of Walter's, and joined the army to escape a life of crime. Protaganist of the book Fable: Blood Ties.
Walking the Earth: He tells the Hero of Brightwall he will be doing this at Walter's funeral, feeling that military life is no longer for him. The Expanded Universe novel Blood Ties follows him on the begining of his journey.
White Sheep: He's the only brother in his family not willingly a criminal.
If You Kill Him, You Will Be Just Like Him: She's the only person who speaks out against executing Logan during his trial since she wants to send out a message that you're a different kind of monarch.
Kicking Ass in All Her Finery: During The Masquerade quest, she accompanies you while wearing an aristocratic masquerade suit.
Rebel Leader: Until the Hero comes along, though she remains in charge of operations in Bowerstone.
The commander of Fort Mourningwood, Swift is an old friend of Walter's who swears to support the Hero in their bid to overthrow Logan if they restore the integrity of the army. He is executed by Logan after his defection is discovered.
The Voiceless: The only noises he makes are some grunts.
Hobson
The player's personal advisor/butler upon becoming the ruler of Albion. His job is to remind them of their Royal Agendas for the day.
Miser Advisor: While he's completely loyal to the player, Hobson almost always tries to urge the player to take choices that puts wealth above all else. While it's understandable considering the situation of the kingdom, he goes beyond that and encourages the ruler to just be a greedy bastard. He's nothing compared to Reaver however.
Villains
Logan (Michael Fassbender)
Aloof Big Brother: There's never any indication that you ever got along with him as your brother or that he ever treated you as anything other than an inferior nuisance. His opinion dramatically changes when you overthrow him.
The Caligula: Deconstructed, he only acts tyrannical because he needs to raise money to save Albion from the Crawler.
Fascist, but Inefficient: Fear of the Crawler and trying to build and army doesn't explain some of the more inexplicably evil things he does, or why he didn't stop doing them once it became obvious he was driving the economy into the ground. It seems that regardless of whether or not he's actually evil, Logan is at least an incompetent ruler.
Breaking Lecture: Whenever it's about, every word from this monster is meant to drive the hero and his/her allies over the Despair Event Horizon. And it has a lot of words to say.
Eldritch Abomination: Defies the laws of physics, can teleport at will, can warp reality, and has complete control over darkness. Think a far less cute version of The Heartless, and you have it.
Evil Laugh: It uses a spine-chilling, always soft chuckle, proving most definitely that it's not a Dead Horse Trope.
Giant Space Flea from Nowhere: It's clearly sentient, but no one knows who or what it is, why it's in Aurora, why it's fixated on Albion... it's just a great big evil thing coming your way, and no explanation is ever provided.
And Your Little Dog Too: Milton decided it to be a good idea to throw a fireball at your dog while having you tied to an electric chair. Bad move. And unlike Fable II, your dog survives this attack.
Kill and Replace: His ultimate plan: use Mary's essence-extracting machine to draw out your Heroic power, transform himself into a copy of you and then kill you so he can take your place and topple the monarchy from within. All the guidance and help he gave was his means of studying you so as to imitate you better.
The Revolution Will Not Be Vilified: He maintains early on that he has no desire to rule, and that the military should simply supervise the democratic process.
Unless that's his way of saying it will be a military dictatorship. Puppet governments and all that. Considering his diary entries advocate the military's involvement so heavily, it's likely this is true, although he sincerely seems not to see it that way.
Professor Ernest Faraday
Expy: Faraday's armoured suit and Logan wanting to use his inventions for war may be a reference to Iron Man.
Evil Genius: Subverted - he never wanted his creations to become war machines.
Fatherly Scientist: He loves his robots so much he'll go to the mat for them in a suit of Powered Armor, despite being quite elderly. His statue even depicts him holding a robot in his lap like a grandfather with a small child.
Mad Scientist: In the form of an army of robots and single-handedly inventing Albion's industrial age, somehow.
Reluctant Mad Scientist: But he ultimately handed over the reigns of his company to Reaver and retired to build what amounted to an amusement park. His creations weren't meant to be weapons - all he ever wanted was to make everyone happy and safe, robots included.
Bio-Augmentation: Her essence-extracting machines and the poisonous balverines she created.
Freudian Excuse: Her grandfather's estate maintained a massive menagerie, which contained balverines. Commander Milton surmises she grew up thinking these were beautiful.
Humans Are Bastards: Mary hates humanity, seeing them as a blight on the natural, ancient order. Her greatest desire is to join "the pure" (balverines, hollow men, and hobbes).
Mad Scientist: Of a more biology-oriented sort than Professor Faraday, but it still involves steam, machines, beakers, and weird chemicals.
Misanthrope Supreme: She hates humans so much, she doesn't even want to be one; Turner roped her in by implying his plans would help her Kill All Humans!.
Motherly Scientist: Just a little. Why else would she build a bubble and light machine for her hobbes to play with?
Playing With Syringes: The other aspect of her mad science, though since Albion predates syringes she just has to make do.
Shoot the Dog: She's genuinely sorry she has to murder a hobbe, a balverine and a hollow man so she can go One-Winged Angel, but does it anyway - though not without a little sadness.
