Being Evil Sucks: At the end he looks genuinely worried seeing M wounded and somewhat realizing he's the cause of this.
Being Tortured Makes You Evil: He was captured and tortured for months on end but he refused to give up any information, until he realized M sold him out and he subsequently tried to commit suicide. Instead of dying he ended up horribly disfigured. Still clinging to life, he realized vengeance against M is now all he has left.
Body Horror: His upper teeth are prostheses to hide his melted teeth and the destroyed left side of his face. The result is a sunken eye combined with a skeletal looking appearance that is unnerving as it sounds.
Dissonant Serenity: He acts very civil and easygoing, which makes his actions and his extremities to do so more terrifying than most villains in the franchise. Plus his smile is really unnerving and it turns out to be an prosthesis to hide the sunken and almost skull-like left side of his face.The result is very disturbing
The Dreaded: When Bond mentions that he wanted to see Silva, Severine began shaking in terror.
Driven to Suicide: In his backstory, he tried this with a cyanide pill, but survived.
Foil: To Bond mostly, though he has elements of Q and M as well. He's an evil agent who uses multiple gadgets, opposed to Bond. He is an expert hacker, opposed to Q. He makes very dark decisions and leads his organization, opposed to M.
He Who Fights Monsters: His desire for revenge on M stems from her selling him out (for admittedly criminal actions he committed). He gets his revenge by doing the same thing to at least five completely innocent secret agents, and planning to do it to many more.
In the Back: A knife is thrown into his back as the killing blow.
Knight of Cerebus: You thought Le Chiffre and Dominic Greene were nasty? You ain't seen nothing yet!
Moral Myopia: There's no doubt he's suffered unimaginable agonies being tortured for months and has more than a Freudian Excuse. Later it's revealed that he had engaged in unauthorized hacking of the Chinese, besides causing the death of innocent secret agents and shooting Severine in front of Bond after she betrayed him.
Psychopathic Manchild: Probably best exemplified at the end when he turns into a crying, scared little boy when he realizes M's death was not going to be a swiftly-painless affair, and proceeds to lovingly embrace her like a mother while begging for her forgiveness.
There Is No Kill Like Overkill: His solution to James Bond pursuing him as he escapes from MI6's underground HQ? Drop a freaking train on him. Of course, given how most incarnations have survived almost everything from stray bullets to heart failure, it's a case of Genre Savvy.
Tragic Villain: Sold out by M, tortured for five months, and tried to commit suicide via cyanide capsule only to end up horribly disfigured, his only goal now is destroy M and die with her.
Uncanny Valley: An Invoked Trope and Justified Trope. His smile seems ... off, and then we learn that he tried to poison himself with cyanide, so those aren't even his real teeth and that the top left portion of his face is sunken in to give a skeletal appearance.
Villainous Breakdown: First when Bond foils his initial plot to kill M. Later, he has another after Bond blows up the Skyfall manor.
Silva: You see, we are the last two rats. We can either eat each other... mmm... or eat everyone else.
"Well Done, Son!" Guy: Even though he wants to M to be punished for what she did to him, Silva still loved her enough as a mother to want to "make-peace" with her through sharing a dignified and painless death.
Eve is an MI6 field agent, who during the mission with Bond in Turkey, ends up shooting 007 while he struggled with Patrice atop a train. Afterwards she is suspended from field work, although she does aid in fighting off Silva in order to ensure that Bond can help M escape safely. At the end of the movie, Eve states she is not fit for field work, and will remain only in a desk job at MI6. As Bond says that they have not been properly introduced, she says her full name is Eve Moneypenny (see also Moneypenny's page here). Despite the fact that the Bond girl in the film is Séverine, Eve and Bond also share a few romantic moments.
Action Girl: She drives like a stuntwoman, is a trained sniper, takes out two mooks with her heels and a metal suitcase and goes on to shoot a few more before eventually deciding that fieldwork isn't for her.
M: Forgive me, but why am I here? Mallory: Three months ago you lost a computer drive containing the identity of almost every NATO agent embedded in terrorist organization across the globe. A list, which in the eyes of our allies, never existed. So, if you'll forgive me, I think you know why you're here.
Took a Level in Badass: Twice. First, when he participates in the gunfight against Silva's mooks, killing two of them and taking a shot for M; and again, when he approves Q and Tanner's breaking of the regulations and put out tracking devices for Silva.
Played by: Albert Finney
An old gamekeeper who still keeps up Skyfall, the Bond family estate in Scotland.
Badass: Took out several of Silva's men with nothing more then his Charles Parker 1878 shotgun and his wits.
What Could Have Been: The producers of the film originally wanted him to be played by Sean Connery, which would have made his first lines with Bone more poignant:
Kincade: James. James Bond! Bond: You're still alive?
Played by: Ola Rapace
A mercenary of unknown nationality with a French name. He works for Silva, and is responsible for setting the events of the movie in action, by stealing the list of NATO field agents' true identities. Is the first of Silvas mooks to die and notable for being the only named one.
