Easily Forgiven: Julia doesn't seem as upset as you'd expect when she finds out that Barbie killed her husband and then lied to her about it.
Fall Guy: Big Jim frames him for all of the murders that he committed. Technically, he did kill Dr. Shumway, but it was in self defence. Dr. Shumway pulled a gun on Barbie during a fight over the former's gambling debts, which the latter was trying to collect. Big Jim calls it murder.
Convicted by Public Opinion: To the point where no-one even questions Big Jim's word against his. When he utters a plea of "Not Guilty" during the Kangaroo Court held for him, the townspeople don't even bother to hear his side of the story and intead jump straight to building a gallows.
A God Am I: Not quite a God, but his ego combined with his realization that his wife predicted the Dome coming has convinced Jim that he and his family have been chosen by divine providence to lead the town.
Affably Evil: For a murderous, power-hungry councilman, Big Jim is actually pretty friendly if you're on his good side.
Even Evil Has Loved Ones: Before going off to kill Maxine, Big Jim tells Junior to stay at home with an almost tearful farewell that makes you wonder if Big Jim knows he might not come back alive.
I've Come Too Far: Most of the murders he commits are Asshole Victims in their own right, but his cold-blooded killing of Dodee after she hears the military chatter discussing his murder of the Reverend, sets him into full villain territory.
I Own This Town: Pretty much sums up his entire character motivation to a tee.
Small Name, Big Ego: Snarkily lampshaded by Norrie, who points out that for a man calling himself "Big Jim", he's really just a petty man who is not above threatening kids to satisfy his need to feel powerful and important.
Villainous Valor: No matter what we think of Big Jim's motives and methods, he is no coward. He leads from the front and often puts himself in danger to save others.
Villain with Good Publicity: A rare example in that the villain actually deserves the publicity. The show makes it clear that Big Jim is a pretty terrible human being... but the town is only seeing him handle potentially serious crises with a level head, and he has saved a lot of lives through his efforts.
Played by: Rachelle Lefevre
Always Save The Hero: Averted. She realises that in order to protect the Egg, she cannot rescue Barbie.
The Chosen One: Is the "Monarch" chosen by the Dome as the one who should protect Chester's Mill.
Dark and Troubled Past / My Greatest Failure: Used to work for a prominent newspaper, until an attempt to disgrace a local politician by using falsified documents blew up in her face, destroying her reputation and leading to her dismissal. She and her husband, Peter, moved to Chester's Mill to escape the scandal.
Show Some Leg: Pulls this on Junior to get him out of the way, so Barbie can rescue Julia.
Spared by the Adaptation: Dies very early on in the book, but is a major character in the show. Subverted as of Season 2, where she is brutally killed by an ax-wielding assailant in the final moments of the premiere.
James "Junior" Rennie
Played by: Alexander Koch
Big Jim's questionably sane son. Deputized by Linda shortly after the Dome appeared.
Antagonistic Offspring: Subverted. He at first appears to betray his dad to side with Ollie Dinsmore, but ends up switching back to his dads side and killing Ollie to save him.
Axe Crazy: His claims to Angie that the dome coming down have messed with her brain apply much more to himself.
After being made a deputy, he dials back on the crazy, but still has a strong undercurrent of being unstable.
Even Evil Has Loved Ones: Seemed pretty upset after receiving the vision from the Dome of Big Jim with stab wounds with he and the other kids holding bloody knives. After seeing that, his first impulse is to go find Big Jim and warn him that he might be in danger.
His entire reasoning for keeping Angie locked up, twisted as it might have been, was due to his concern the Dome was "making her sick".
Teeth-Clenched Teamwork: Often gets forced to work with Barbie, a man who he distrusts and dislikes. Later, he ends up having to help the other three Hands, even when his goals and theirs are fundamentally incompatible.
Token Evil Teammate: For Joe, Norrie, and Angie, when it's revealed that he's the Fourth Hand. This means that they often need his help even when they're working at cross purposes from each other.
Police Are Useless: Despite any good intentions, she's clearly not cut out for the position of Sheriff, due to an inability to keep a leash on her deputies, and being bossed around by Big Jim, whom she technically outranks.
Even Evil Has Standards: May be actively encouraging the manufacture and sale of a highly addictive and dangerous designer drug, but is morally offended when Barbie asks if she plans to start a brothel as part of her black market.
That being said, her outrage actually stems from the fact that her mother was forced into prostitution, due to not being able to find a job in Chester's Mill after they shunned her for her Teen Pregnancy. If this had not been the case, it's very likely Maxine would have had no such scruples about doing so.
Axe Crazy: Taking drugs and hearing voices makes him increasingly insane
Church Militant: Decides it's a good idea to steal and destroy as much of the medicine in town as he can, because he thinks it's God's plan.
Entertainingly Wrong: He believes God is speaking to him and directing him to the story of "Moab". It later turns out that he was really picking up military com-chatter via his hearing aid, who were attempting to breach the Dome with a "M.O.A.B" strike.
Big Jim's late wife, and Junior's mother. An aspiring artist who died several years before the series begins. Played by: Sherry Stringfield
Cassandra Truth: Her attempts to warn her husband, Big Jim, about the Dome were written off as insanity, putting strain on their marriage.
Driven to Suicide: A particularly nasty argument with Big Jim drove Pauline to commit suicide by crashing her car into a tree. Big Jim and Duke Perkins covered it up and paid off the sole witness to make it look like an accident. Season 2 reveals that she actually faked her death, and is living in another town named Zenith.
Faking the Dead: Faked her death in a car accident to get away from Big Jim's influence in her life. But ultimately she's...
