Boisterous Weakling: In his final battle with Alphonse, Lucas taunts Alphonse in order to get him into the moonlight so he can turn Werewolf!Alphonse back to his normal self. It doesn't exactly work out that way.
Brains and Brawn: In the Jekyll & Hyde sense, Lucas is both of these depending on whether he assumes human form or werewolf form. While his human self can crack safes and swim, his werewolf self can break rocks, push crates, and dig.
Cursed with Awesome: Although Lucas ultimately fails in getting the amulet off, he still has the ability to turn into a werewolf. Even though he doesn't generally use his strength to win fights, he does use his size to intimidate others—and in one case, this intimidation leads to his home not being needlessly demolished.
Magic Pants: Lucas often needs to transform back and forth between his human and werewolf forms to solve puzzles. Yet, his clothes don't tear or rip much, and they're practically the perfect size for whatever form he's in. At most, his slacks tear at the knees, and he loses the white collared shirt as a werewolf.
Men Can't Keep House: Lucas's home has clothes and papers strewn all over the floor. Even after he gets furniture, Lucas mentions that he'll deliberately continue to throw his clothes on the floor and leave the dishes unwashed.
The Mind Is a Plaything of the Body: As a human, Lucas tends to be a bit of a coward prone to making snarky jokes. In contrast, Werewolf!Lucas would rather chase cars or howl at the moon.
Non-Action Guy: Lucas isn't much of a fighter in either human or werewolf form. He's more likely to talk his way out of complicated situations.
The Nose Knows: Lucas notes that he has a heightened sense of smell as a werewolf, to the point where he can smell the history of where an object has been.
Unlikely Hero: Lucas was just an average guy trying to pay his rent before he was hired by Harvey to steal the amulet. After, he gained the power to shapeshift into a werewolf, fought and then made amends with the local street gang, worked with an Intrepid Reporter to find evidence to expose the resident corrupt millionaire, turned said millionaire into an even bigger and badder werewolf, and eventually confronted that millionaire and turned him into a cute, little puppy.
Big Bad: The entire game builds up to Lucas confronting Alphonse over the crimes he's committed against the city and about Lucas's affair with Anna.
Big Little Brother: Though Alphonse is Mayor Bruce's younger brother, an image of them as children shows Alphonse as the physically bigger child who bullies his older brother.
Dark is Evil: In contrast to Lucas, Alphonse has black hair, wears a black suit, and has grayish skin.
Evil Is Petty: This is one of Alphonse's defining traits. Among other things, he pressured the mayor into banning the performing arts, just so he could get revenge on Lucas for seducing his girlfriend.
For the Evulz: Some of Alphonse's crimes fall under this. For instance, there's no reason for him to demolish an orphanage, pollute the river, or steal candy from a baby, other than the fact that he wants to.
I Own This Town: Mayor Bruce signed his authority over the city over to Alphonse, allowing him to make whatever new laws he desired.
Man of Wealth and Taste: In spite of his evil deeds, Alphonse's nice suit and tie show that he knows how to dress well.
Narcissist: He has busts, statues, and paintings of himself everywhere. Lucas remarks on the ridiculousness and squickiness of the partially nude, full-body statues Alphonse has in his treasury.
Rich Bastard: Alphonse uses both his money and power to gain absolute control over the city and to act like a petty jerk to Feyre's citizens, especially Lucas.
Shapeshifter Mode Lock: Alphonse is stuck in werewolf form after he grapples with Lucas, and Lucas discovers that if he doesn't change Alphonse back, he'll lose his mind and stay a werewolf forever.
Siblings in Crime: With his brother, the Mayor. However, it's shown that Alphonse is the worse brother, considering he actively alters the city's laws in order to commit oppressive and evil acts, whereas his brother is more of an Obstructive Bureaucrat.
Well-Intentioned Extremist: Subverted. Lucas wonders if Alphonse started out doing good things to try to improve Feyre…but then he immediately dismisses the possibility.
White Collar Crime: Alphonse has committed a few of these, such as bribing the local newspaper or embezzling funds.
Hypercompetent Sidekick: Strump can reroute power from his van to open all of the locked doors in Feyre, but doesn't do so unless Lucas specifically asks him to help him solve one of the block puzzles. It's also implied that Strump also knows how to solve each room, since he gives Lucas hints.
Jade-Colored Glasses: Strump used to be a motivated hero cop before Alphonse forced him off the force. Now, he's more obsessed with taking down Alphonse for ruining his career.
Lawman Gone Bad: Inverted. The force Strump has defected from is full of dirty cops who work for Alphonse. Strump's been ostracized by them because he refused to take bribes.
Reluctant Retiree: Strump had a successful career on the force before Alphonse had his badge taken away for not taking bribes and letting Alphonse's criminal activities slide.
Trenchcoat Brigade: The trenchcoat, five o'clock shadow, cigarettes, and hard-boiled personality are all there.
Evil Smells Bad: If there's one thing Ruby and Lucas can agree on, it's that Harvey smells bad.
Cranky Landlord: Harvey really stretches this to the extremes—not only does he bother Lucas about paying the rent, but he also threatens to raise it and forces Lucas to steal for him.
Greed: Harvey's motivation for stealing the amulet. Harvey's motivation for doing anything, actually.
Jerkass: Harvey's never short of rude comments for Lucas.
Pet the Dog: When Lucas gives Harvey the scarf Grandma MacGuffin made for him, Harvey asks Lucas how much he wants for it. When Lucas says that it doesn't cost anything because it's a gift, Harvey's touched by the kind gesture and returns it by giving Lucas the Advanced Lockpicking Kit for free.
Sinister Schnoz: He has a pretty huge nose, and it's not of the elegant, gorgeous kind.
Hot Scoop: Although her age shows a bit, there's no doubt that Judy's still hot enough to rock a mindress.
Intrepid Reporter: Subverted. Though she's an investigative reporter, she has Lucas do all of the legwork for her in obtaining evidence against Alphonse.
Meganekko: Judy has a pair of brown, round-framed glasses, which enhance her Hot Scoop status.
Badass Beard: As the leader of the Crows, Grim's beard makes him look even more tough and rugged than he already is.
Badass Biker: Grim characterizes himself as this. He explains to Lucas that anarchy is the only option the Crows have for a town as corrupt as Feyre.
The Stoic: He doesn't even flinch when first confronted by Werewolf!Lucas.
All Bikers Are Hells Angels: All of the Crows have leather jackets, dark shades, tough attitudes and are prone to vandalizing the city.
Chain Pain: A few of the Crows are seen with chains as weapons instead of their trademark crowbars.
Cool Shades: All of the Crows members, with the exception of Grim, wear dark sunglasses.
Fortune Teller: Rena sends Lucas out to get a book from the library so that she can practice Advanced Fortune Telling, by which Lucas can receive hints for secret rooms in the game.
Hot Gypsy Woman: Lucas constantly flirts with Rena and remarks on her hotness.
Tattoo as Character Type: Rena has a sleeve tattoo on her left arm that helps define her exoticness and mystical powers as a psychic.
Corrupt Politician: Although Mayor Bruce isn't as corrupt as his brother, he's not below abusing his power to make Lucas's life miserable in Feyre, first by barring him from applying for a job, then trying to tear down his home.
Obstructive Bureaucrat: Mayor Bruce makes Lucas gets four names for a petition in order to get the security guard's badge back.
Siblings in Crime: With his brother Alphonse. Alphonse, though, is the more powerful of the two.
Ultimate Authority Mayor: Subverted. Although it seems like the Mayor is letting his brother abuse his power in Feyre, it's revealed that Mayor Bruce can't do anything to Alphonse because Alphonse blackmailed him into signing away all his authority to him.
Minor Major Character: Although Anna is the driving force of the animosity between Lucas and Alphonse, she never shows up as a character—we only see her in flashbacks.
Missing Mom: She leaves Ruby on Lucas's doorstep when she flees town, but we never learn of her reason for leaving.
