A big element of Family Guy Fanon is that it doesn't shy away from expanding upon the original show. Whether it be expanding characters, episodes or story arcs.
In General
- The adaption gives a reason for why Beth Bethany, a friend of Meg's, stopped appearing after "Peter's Daughter" in "Scammed Yankees". With it being explained that she committed suicide.
- The adaption expands on how Francis and Thelma met (which went unexplained in the original). With the two meeting while performing for a show called Hope & Rape (which was a deleted scene from Season 5's Mother Tucker in the OG)
- The adaption gives a reason for Cleveland Jr.'s more enlarged state compared to his skinny look in the first few seasons. With "Breadlosers", the first episode where he appears with the new look, with Cleveland revealing it to be a side-effect caused by Ritalin.
- While seen on The Cleveland Show Fanon, the adaption adds a real conclusion to the show called "Cleveland Moves Out
". And gives a reason for why The Browns move to Quahog as one of the blown-up pieces of a meteor crushes The Brown-Tubbs House and they have no hope in repairing their house because Cleveland and Donna got fired from their jobs and can't get money anymore. - It expands on Meg's real father, Stan Thompson, who was originally an unseen character mentioned in "Screwed the Pooch", but retconned to actually be a real person who Meg reunites with in Season 21.
Expansions on Characters
- Chris gets a big expansion here compared to the original, to make him stand out more as a main character. In the original, he was more of a side character than a main character, who didn't offer much aside from being the Dumbass Teenage Son and many of his plots weren't that interesting (he gets better in later seasons however). In the fanfic, it gives him more of a personality by expanding upon his more artistic side (which was only seen in the first two seasons than forgotten entirely in the original) that leads to him having more unique plots like "Peter Gets Served", which had Chris' artwork get stolen and passed off as someone else's, or "NFT Guy", which has Peter sell Chris' art as NFTs behind his back.
- Herbert gets a good expansion too. With his character page expanding on his childhood, him getting outed as a homosexual pedophile, and even gets an episode to introduce him, whereas the original had him be there already, but not appear until Season 3 with no explanation.
- Kevin Swanson has a small bit of expansion. With him getting an episode where he signs up for the draft and is accepted to fight in the Iraq War in "Full Metal Jackass" and has an episode where he has trouble with simply going back to the way things were after the war in "7th Kevin".
- A few of the Ascended Extras are given expansions on their personalities:
- Randall Fargus, a bit character in "Running Mates" is expanded to be a Absent-Minded Professor who's a free-spirit and loves to create inventions to have fun. So much so he opened an attraction called Fargus' Wacky World of Mayhem that hosts a lot of his inventions. He's even given a wife and kid in this adaption while in the original, he was by himself.
- Change for a Buck, a character that didn't even speak in "The Son Also Draws", is expanded to be more than a guy behind a cashier, with him noting after he loses his job in "Meg for Mercy", he doesn't want to con people out of their money again and wants to work a legitimate and ethical job. He does however end up opening a casino, so...
- Vinny, the temporary replacement for Brian, is able to show more bits of his past with his increased screentime compared to the mere two episodes he got in the original. "Mobsters Inc." added that Vinny was an ex-mobster, which he needs to back down from in "Ganging Down" and is even revealed to not be a certified American citizen, but rather, an illegal Italian immigrant (the same way Peter was a Mexican immigrant) in "Boopa-Dee Bappa-Dee". His relationship with Stewie is expanded more and the two have a more natural building bond to the point prior to "Christmas Guy" in this adaption, he helped Stewie find Brian in "A New Lease on Death", celebrated a Thanksgiving with the Griffins in "Turkey Guys" and even went on a Road To with Stewie in "Road to New York".
- In Season 18 onwards in the original show Quagmire's sex offender antics start to get downplayed to the point of non-existence due to the #MeToo movement. But here, he actually goes through an arc about him learning to stop being a sexual deviant in "The Quagmire Show", due to going under fire from the #MeToo movement
- Bernice, a small character who was Cleveland's girlfriend that appeared a few times in the original, gets an extended role in Season 6 with a side plot of them dating. Though in this adaption, she's expanded to be an abusive girlfriend that's just as bad, if not worse, than Loretta.
Expansions on Episodes
- "The Guyfathers" (which is actually There's Something About Paulie), expands upon Big Fat Paulie's friendship with Peter (and Francis due to him being added in the episode). In the original, Peter and Paulie became friends after merely hanging out for a movie, and as such, their friendship didn't feel as realistic or had weight. And it also didn't make sense for Peter to invite someone who he only knew for about a few hours to his house. Here, Peter and Francis were instead tasked with spending an evening with Paulie on the town instead of just taking him to the movies. The three head to multiple locations where they begin to bond and grow a friendship more naturally. And the three spend a few days together hanging out, giving them a stronger bond. It also gives Peter more of a reason to invite Paulie to his house, as he's hung out with him enough to trust him.
- "15 Minutes of Embarrassment" (which is actually 15 Minutes of Shame) expands on the Griffins having their own reality show and them having segments on the show. With Peter hosting a segment on his boat, telling the audience about his fisherman job, and Chris doing a live Hangman segment where people called a number to reach him and guess the phrase he thought of.
- "Long John Peter" expands upon the pirate plot. While in the original it lasted only the first third, it's been promoted to the main plot now. And adds a few extra details to it too, with Peter, Francis and Chris having to save Lois, Thelma and Anna after the former two steal British man Shelly Boothbishop's products and kidnaps them as ransom as revenge. As seen too, it also connects the Chris subplot with Anna getting shanghaied by accident.
- "Seahorse Seashell Party" expands on Meg's speech to Peter, with her bringing up reckless actions he did that harmed others (burning down Mort's pharmacy, getting Quagmire fired from his airport job and terrorizing Quahog while in his "Long John Peter" shtick and blowing up a children's hospital are a few) and a couple examples of him being a jerk to Meg (chaining her up in the cellar, mistaking her for a housecat and locking her outside are a few examples).
- "Finders Keepers" scraps the opening bit with Peter's bad breath to focus more on hunt for the treasure and how it turns the Griffins against each other for it.
- The original "Life of Brian" episode is expanded into a two parter. With Vinny not coming into the family until the second part, "A Filler in Need". Not only is this used to expand upon the emotions of the family after Brian's death, but it also gives the plot more time to breathe compared to the original.
- "Griffin Winter Games" adds more edited scenes to establish how long Meg's been training for the Olympics. The added scenes are:
- Meg and Kevin skating together from "A Very Special Family Guy Freakin' Christmas" (based from the fanon version)
- You Cheeky Bastard from "PTV"
- Cool Whip from "Barely Legal"
- The song "A Bag of Weed" from "420"
- Peter riding a Dondon in "Something, Something, Something, Dark Side"
- The 12-way-sex recreation from "12 and a Half Angry Men"
- Brian's death from "Life of Brian"
- Meg and Lisa trying to find Meg's talent from "The Simpsons Guy"
- Brian realizing he's permanently married to Jess in "Married ... With Cancer"
- And a fake scene, where Peter skis with Meg and gets hit in the testicles with a bag of nickles.
- "Disney's the Reboot" expands on the third act, with more short versions of shows in Family Guy including Big Mouth, Young Sheldon, F is for Family, and Black Mirror.
- "The Candidate" expands on the opening story with Peter and the Beer Bar Buddies riding an app-controlled scooter, with it being the B-plot of the episode while the A-plot happens in the front ground. It includes them going to more locations, and have an added issue with them not knowing how to stop the scooter.
- "La Famiglia Guy" expands on the third act and has Susie get kidnapped by the mafia to be held for ransom. And gives Peter and the gang extra motive with them needing to save her.
Expansions on Story Arcs
- Compared to the original, Peter's shown doing his dream job as a fisherman more in the third and fourth seasons. Whether in the "The Fat Man and the Sea" when he tried to catch the legendary Pendragon fish, or him even holding two weddings on the boat.
- In the upcoming twenty-second season, the story arc will get a sequel where Peter returns to his fisherman job.
- Compared to the real show, where the story arc only lasted three episodes, the Brian's Death story arc lasted an entire season (Season 11). Allowing Vinny to show more sides to him, with the fanfic making him to be originally part of mobster lifestyle before taking residence with the Griffins and expanding on his Italian roots, and his relationship with Stewie having more weight.
- Brian's subplot about moving out of the house for a while in Season 16 lasts half the season compared to a mere three episodes like the real show. And as such, it expands upon his struggles with being on his own. From him searching for a job to pay his rent (which he ends up with the Suicide Hotline job that he got in the original), the added struggles with working at the Suicide Hotline (working his Jerkass boss Lance Prueher who belittles and snidely humiliates him in front of the other workers, whenever he messes up), and his struggles while having a broken leg that leads him to become a cop since Joe was able to be one in a wheelchair (to disastrous results).
