Pet the Dog: He rubs the head of a dog as he enters the boat during the climax and it is shown that he actually cared about longtime partner in crime Fenster, even requesting that he be given a proper burial on the beach.
Jerk with a Heart of Gold: He does care for Edie and for Verbal's safety (or so Verbal says) but when you look into his past he seems just as bad as the other characters. Which is another sign that Verbal's story isn't what it seems.
It didn't make sense that I'd be there. I mean, these guys were hardcore hijackers. But there I was. At that point I wasn't scared, I knew I hadn't done anything they could do me for. Besides, it was fun. I got to make like I was notorious.
Academy Award: Kevin Spacey won the Academy Award for Best Supporting Actor in the role of Verbal Kint.
Be as Unhelpful as Possible: Inverted, as Verbal spills a lot of the suspects' exploits to Kujan until you realize he's only telling the story to buy time until his release, and that most of it was a big fat lie.
Consummate Liar: Verbal is actually talking about himself when he speaks of Soze!
Line-of-Sight Name: Many details from Verbal's story turn out to be taken from objects in the room. Verbal is seen looking around the room before his interrogation, and a later shot even shows him looking up at the bottom of Kujan's coffee cup.
Meaningful Name:Keyser Söze is either German or Turkish. Kaiser, a homonym of Keyser, is the German word for emperor, and Söze means "talks too much" in Turkish, making Keyser Söze "Emperor Talks Too Much," a hint that he is "Verbal" Kint, who says he's accused of talking too much.
Personal Effects Reveal: The golden watch and cigarette lighter given to Kint as he leaves the police station are the same items that Soze is shown to possess at the beginning of the film.
Saying Too Much: Verbal actually does admit to killing Keaton, although it is fairly unintelligible due to Kujan's yelling, and he quickly shades the slip-up by covering it with, "I did see Keaton get shot."
Ax-Crazy: Soze's backstory told by Kint portrays Söze as this. It turns out that when Kint is detailing all of this to Kujan, he's really talking about himself, so in hindsight, either Kujan has an authentic, first-hand account of Soze's exploits, or a highly exaggerated account from the actual person so that he can build himself up while Kujan does not know the truth.
The Bad Guy Wins: He successfully manages to escape the police as Verbal by making up almost the whole story of what happened.
Papa Wolf: Although, he shoots his wife and children after being unwilling to let them live another day after what they've been through.
Shrouded in Myth: Unlike most associated with this trope, Soze actually lives up this reputation.
They Look Just Like Everyone Else: Referred to as "The Devil", but looks just like a normal man, albeit an extremely dangerous one. This is why Verbal would have been the very last person on Earth that Kujan would have suspected to be Keyser Soze.
Unstoppable Rage: He killed his wife and children to stop the home invaders from using them as hostages, then killed all but one of the invaders (so he'd go tell his associates), then went out and killed everyone connected with the people who did the home invasion of his house, including people whose only connection was that they owed money to them or had dealings with them.
Walking Spoiler: You do see how much of this section is highlighted, right?
Dave Kujan (Chazz Palminteri)
You know the first thing they teach you in the academy? How to spot a murderer.
Secret Test of Character: Agent Kujan tells Verbal that the best way to weed out a professional criminal is round up five guys and place them in a room together. An innocent man will be constantly fretting about what might happen, while the guilty party is going to be calm, trying not to give anything away, and resting as much as possible so he can be sharp when the police question himd. Hockney, who is revealed after the fact to be responsible for hijacking the truck from the start of the movie, is the only one not freaking out during the prison scene, and even starts getting upset at how worked up Fenster is.
Dissonant Serenity: Sees his two bodyguards shot from either side of him, yet still keeps his cool, even when McManus proceeds to point a gun at his head.
Even Evil Has Loved Ones: Uses this as a ploy to blackmail the Suspects if they don't cooperate by disclosing that he knows the whereabouts of their closest relatives.
Evil Brit: His ethnicity is never confirmed, although "Kobayashi" is a Japanese name, which is contrasted by Postlethwaite giving the character a British-Indian accent. And then there's the fact that Verbal's entire story was fabricated, so "Kobayashi" is not even his real name.
Manipulative Bastard: (With orders from Soze), he cons the Suspects into stopping the dope deal on the Hungarian mob's boat by presenting envelopes detailing every crime they have committed in the past, and threatening the lives of their loved ones.
No Name Given: No real name, in any case. Kint took the name "Kobayashi" from the bottom of a coffee mug.
The Stoic: Never shows any kind of emotion, even in the face of death. Of course, Keyser Soze will do something worse to him than simply death.
