Jimmy James Fitzsimmons is the resident bully and recurring antagonist who often picks on children younger than him, his main target being Bill Murphy. Jimmy is the most foul-mouthed youth in the town. As revealed in O Holy Moly Night, he is an altar boy. He is voiced by Mo Collins.
In Season 1, Jimmy serves as a major antagonist for the Murphys, along with his dad. However, at the end of Season 2 to Season 4, he bullied Bill less after Bill rescued him by sending him to the hospital. Jimmy doesn't harass Bill in any moment in the fourth season, but is susceptible to child neglect by his father.
Jimmy usually hangs out at his clubhouse. He likes to smoke cigarettes and is sometimes accompanied by his two cronies. Jimmy likes to bully Bill because he is known to be a pussy. He got in a fight when Bill punched him, causing his wood shop project to break. Jimmy's father works at the school as a janitor and it's also implied that he is one of the bus drivers and the Pool Cleaner.
In "O Holy Moly Night", Jimmy explains that one time, the milkman refused to give him some heavy cream. As a result, he stuck a pencil in his leg, which resulted in him becoming an altar boy at the church, even being promoted to head altar boy throughout that time. When Bill first became an altar boy himself, Jimmy immediately trained him in the ways, and also revealed that he was respecting Bill's recent display of courage at standing up to him. Though he inadvertently goes back to being Bill's enemy when he refused to help steal the golden chalices from the church, and after Bill accidentally spilled wine on his surplice. Later, he and his father went over to the Murphy's because of that indiscretion, which made both the Murphys and the Fitzsimmons get into a fight, which ended after Sue hit Jimmy's father with a baseball bat.
In Season 2, Jimmy is still shown to be overly harsh and bullying towards younger kids. Halfway through the season, Bill steals a hockey stick and blamed it on Jimmy (since he's the one who took a fraction of the money before Bill could purchase the stick). As a result, Jimmy's father sends him to a Catholic reform school to straighten him out.
Although his father's check bounced after a few weeks, Jimmy undergoes a major personality transition and sets off to make amends for those he hurt, including Bill and Phillip. Unfortunately, when Jimmy was apologizing to Phillip, he unintentionally tells him that Bill's the one who sent him away in the first place, causing Jimmy to change back into his old self as he got very angry, having every right to considering how Bill was joyful when Jimmy himself was sent to reform school over What bill had done to him.
The two of them along with Ben and Kenny then decide it's time they gave Jimmy something he deserves and schemes up a major plan to ruin him. However, the plan goes south when Jimmy wises up on the four, but they end up getting satisfying results anyway when Randy hits Jimmy with his van. As Ben, Kenny, and Phillip runoff, Bill single-handedly takes Jimmy to the hospital to get his injuries treated.
After this, Jimmy thanks Bill for the deed, but he still admits that he'd do something much worse if it was the other way around and will no doubt give Bill a major beating once he recovers. During this time, Bill meets Jimmy's sister and instantly becomes smitten with her.
In Season 3, he continued to beat Bill up to keep him away from Bridget. Later it's revealed Jimmy was actually trying to protect Bill from her, as she turns out to be worse than he is. He also considers Bill to be his best friend, still remembering the day he saved him.
In season 4 he is quick to defend Bill at a hockey game but soon gets angry and jealous that his dad shows more attention to Bill than him (his own son). He is later shown beating on other players including his own goalee Philip, Jimmy gets beaten up by the rival team and Philip takes advantage of this by punching his face in.
Jimmy is like any other bully, constantly picking on weaker kids and treating them like crap. He is also known for being a liar, for instance, when he told his dad that Bill was the one who planned to rob the church, even though it was really him.
Despite his tough guy attitude, he seems to have a fondness for anyone who "has balls", which was why he didn't do anything bad to Bill for assaulting him and for burning down the city's forest.
Jimmy is also a skilled craftsman, as evidenced in "Bill Murphy's Day Off" when he easily built a birdhouse that got him an A in wood shop class, and later on, when he built a wooden boy he named "Peppito". This reveals a secret softer side of Jimmy, as also evidenced by the various stuffed animals in his bedroom.
In Season 2, Jimmy is still portrayed as a chaotic, aggressive, and mean. However, when he's blamed for stealing, his father takes him to a Catholic Military School, where despite only being there for 2 months (he's released after his father's cheque bounced), he undergoes a major personality transition, becoming a much nicer and more caring person. This doesn't last very long when Phillip tells Jimmy that Bill's the one who framed him for stealing, prompting him to go back to his bullying ways.
Ever since Bill got the idea to say his name is Jimmy Fitzsimmons when he got in trouble, it has become a running gag for other people (kids and adults), all over town got the idea to do the same thing and even use the same name, for other bad things. In "Pray Away", Randy accidentally hit Jimmy with his van, and nervously drove off, shouting "My name is Jimmy Fitzsimmons!" In "Paul Lynde to Block", Bill and Maureen saw Julie in a stall in the women's restroom at the drive-in theater, which scares them and they run off with Bill saying "Our name's are Jimmy Fitzsimmons". In "Summer Vacation", Chet snitched on Frank for building an extra room on his house without a permit, and said his name was "Jimmy Fitzsimmons". In "Father Confessor", both Bridget and their father confess to Father Pat about a misdeed they each did and blamed it on Jimmy.
Bridget said that she put nail-polish in Jimmy's insulin, causing him to temporarily go blind in his left eye. This suggests that Jimmy is diabetic.
The fact that he tries several times to Protect Bill from his sister shows that he may actually care for his bullying target.
However, ever since Bill rescued Jimmy by sending him to the hospital after getting injured in a hit and run incident by Randy, he eventually becomes nicer to Bill and has started to bully him less (when they played hockey and Bill was getting beaten up by an opposing team player, Jimmy immediately rushed in to help Bill). Throughout Season 4, Jimmy hasn't been seen bullying Bill, but is instead neglected by his father most of the time when he views Bill as his "son". This made Jimmy have low self-esteem and angrily confronted Bill on how he was being treated like dirt, whereas he is being viewed as a son by Jimmy's father. When Bill saw Mr. Fitzsimmons' mistreatment toward his son, he does the right thing by getting himself benched, leaving Jimmy to take over his position for his father to see the true personality of his child.

- Like his sister Bridget, Jimmy heavily resembles his father and is pretty much a younger version of his father personality and looks wise, except Bridget is nowhere near as ugly as Jimmy or Mr. Fitzsimmons
- Jimmy is diabetic.
- He is likely based on Scut Farkus.
- His last name suggests he is of Norwegian descent as his last name is of norse origin.
- Jimmy is blind in his left eye from when Bridget put nail polish in his insulin.
