Lots of fictional families seem to have that one uncle that all the kids just love. Most often, he's a young bachelor who has no intention of settling down any time soon, though he may have a girlfriend. He may travel a lot and wow the kids with stories of meeting celebrities and traveling the world (and if so, he always brings back the coolest souvenirs, which he naturally gives away as presents). Or he may be well-off and spoils his sibling's kids whenever they're together.
Regardless, he will often be secretly envious of the stability and loving home life that his brother or sister enjoys, even as he boasts of his own independence. The uncle may be the Black Sheep of the family. If his nieces and nephews ever lose their parent, he's the one who usually steps in to become a Parental Substitute.
This trope is usually male, but the role will occasionally be taken on by an aunt.

- Bakuman。: Nobuhiro Mashiro, also known under his pen name Taro Kawaguchi, was this to his nephew Moritaka Mashiro. Mashiro admired his uncle's work when he was a little child and the series shows several times that other characters are fans of his work. However, Nobuhiro's death not only hit Mashiro hard, the young Mashiro believed that his uncle committed suicide due to his current lack of success rather than being killed by overworking, which causes Mashiro to lose faith in becoming a mangaka.

By the time he realizes that she's the "nonexistent person" and has to be killed in order to end the calamity, he realizes that he's come to think of her as being like his mother.
- In the Fantastic Four:
- Reed and Sue's children consider Johnny to be a cool uncle since he's a superhero that sets himself on fire. Ben also gets this treatment although he's not related.
- Doctor Doom of all people is considered to be this by Valeria Richards since he is basically the relative that spoils her the most. That, and he indulges her Token Evil Teammate tendencies. You'd think that'd be something he'd try to hide, to save face (er, mask), but no, he has placed her under his royal protection, and allows her to call him "Uncle Doom".
- Spider-Man's own uncle Ben was a pretty cool guy since he fought in World War II and shaped Peter into the man he is today.
- Scrooge McDuck may count like this to Huey, Dewey, and Louie.
- The Flash:

- Persepolis: Marji really liked her kindly Uncle Anoosh, who told her stories of participating in a rebellion against the Shah and his stay in the USSR. She was quite brokenhearted when the authorities executed him on suspicion of being a Soviet spy.

- In Ghosts of Evangelion Heishiro is Ryuko's cool honorary uncle who taught her to skateboarding and other cool stuff (although Asuka thinks he is a brat).
- HERZ: Rei to Shinji and Asuka's daughter Akiko. She gives Akiko toys (some of them handmade), tells her stories and tales, is very protective of her... and Akiko loves her aunt.
- In Nexus, Dante is certainly one because it's well... him. Though he would argue that he sees himself as more than just an uncle.
- Apollo to Armani in the Broken Bow series. Doubles as a Parental Substitute, since Artemis wasn't aware of the latter's birth until sixteen years later.
- In The Second Try, Rei. Her niece Aki adores her and loves spending time with her. In turn, Rei protects her and looks after her. Although, neither of them were aware that they were related when they met. This relationship continues in Aki-chan's Life. They also double as a Moe Couplet.

- House is this by association to Wilson's niece Jennifer in the fanfic In The Year 2025.

They have an "uncle-off" in one installment, by which they try to determine which of the six is her favorite; one of her mother's brothers is absent, so he can't participate, and honorary uncle Varric (the "whiskey uncle") abstains, but the other four have great fun with the competition.
- In Imaginary Seas, Percy realizes that his beloved teacher Chiron, a son of Kronos, is technically his uncle. Percy doesn't dwell on it much though, as he is far more interested in whether or not Chiron was a robot like the Olympians.

Lisa: That was very rude of you, Adrian.
Adrian: ...was playing.
Lisa: Not good enough. Now apologize to Death.
Death: It is alright, My Prince. But perhaps I may make a request for the next time? You see, if you could scratch just between the fifth and sixth vertebra...
Dracula: Don't encourage him, Death.
- In the Danny Phantom fanfic Resurrected Memories, Ember has become this to both Zoe and Maggie, though none of them know it yet.

- In Yugioh EQG: XX, technically Flash Sentry is Flurry Heart's godfather, not her uncle, but he is dating Flurry Heart's aunt Twilight Sparkle, and happily states that he loves Flurry Heart and is more than happy to babysit her and do all the fun "aunt and uncle" activities with her when Twilight is too busy. Flurry Heart also loves Flash and considers him one of her favorite people.
- Children of Remnant: Watts seems to strive to be this, serving as a mentor to Blake and getting Jaune alcohol for a party.

- Frank in Gifted. He encourages Mary's academic interests while still encouraging her to act like a kid, and loves to take her to the beach or out for a ride on boats he's finished fixing. From an adult perspective, it doesn't hurt that he's played by Chris Evans.
- Park Nam-joo from The Host is a Cool Aunt with a bronze medal in archery. She seems to be her niece Hyun-seo's favourite relative.
- Uncle Red from Silver Bullet is practically idolized by his nephew Marty.

- Mystery Road: Jay gets offered useful insight and information by a genial old local man who calls him nephew in two scenes.
- Absolutely Truly: Truly's Aunt True acts as this to her.

A great part of the first book revolves around his nieces starting a private war with him, since he's taken up writing and become distant, therefore, in their minds, ceasing to be cool.
- Discworld: City ruler Lord Havelock Vetinari is the epitome of cool and cunning. But from the novel Night Watch onward, the character of his only living relative, the aunt alluded to in Guards! Guards!, is opened up a little: it is hinted that Vetinari learned a lot of his skills from Auntie Bobbie (Lady Roberta de Meserole), who is a political manipulator, a Seamstress where she needs to be, possibly one of only a handful of female Assassins, and a lady of guile, insight, cunning, and wisdom. She has certainly raised Havelock in loco parentis after the undetailed death of his parents. A second wise woman in Havelock Vetinari's life, an aunt-like character, has been the vampire Lady Margolotta (although some interpretations hint at a sexual relationship).
- In Noel Streatfield's Theatre Shoes, Mose and Lindsey Cohen are both very kind and helpful to their nieces and nephew, Sorrel, Mark, and Holly Forbes. Mose Cohen is a famous comedian, adding to his coolness.
- In Marcia Martin's Donna Parker: Special Agent, Uncle Roger fills this role. He's the black sheep of the family, and no one in Donna's family had seen him in many years. Donna suspected that he might be an impostor. She was wrong.
- A Song of Ice and Fire:
- Tyrion Lannister loves his niece and nephew Myrcella and Tommen and they love him too. (The situation with Tyrion and his other nephew Joffrey is rather different.)

- Theon remembers his uncle Aeron being this way in his youth, but upon his return home finds that Aeron has discovered religion sometime in the last ten years and becomes considerably less fun than the rowdy, drunken womanizer he remembers.
- Theon's sister Asha considers her maternal uncle Rodrick "the Reader" Harlaw this, though unconventionally; he rarely leaves his home and the gifts he brings back are books, advice, and political support. Of course, the field of competition is not strong; her paternal uncles consist of a dim-witted brute, the aforementioned sour religious fanatic, and an Ax-Crazy schemer.
- There's also Catelyn Stark's uncle Brynden Tully, who is definitely this trope with regards to her and her siblings, Lysa and Edmure.
- Eddard Stark's younger brother Benjen Stark (who is First Ranger in the Night's Watch) is a Cool Uncle to Ned's kids, especially to Ned's illegitimate son Jon Snow, who adores his uncle and has wanted to join the Night's Watch his entire life like his uncle. Like their brother Jon, Arya and Sansa also idealize the Watch based on their uncle, and Benjen is held in high esteem by his other nephews Robb, Bran, and Rickon as well. While Benjen loves all his nephews and nieces, he seems to have an additional soft spot for his nephew Jon.

- Uncle Flynn the ne'er-do-well gambler in humorist Patrick McManus's (fictionalized) stories of his Idaho childhood.
- Sunny's aunt Chinwe is a female version in Akata Witch. Her sisters, one of them being Sunny's mother, both became doctors. Chinwe was also supposed to become a doctor because that was their father's ambition for them, but instead, she became a professional dancer and married an American. Sunny looks up to her aunt because she is the only other person in the family who doesn't quite fit.
- Harry Potter had Sirius Black and Remus Lupin, neither of whom were actually related but who nevertheless filled the role.
- Doctor Sleep: Dan to Abra, whose mother Lucy was the product of an extramarital fling by their mutual father, Jack Torrance.
- Lots of these in the Village Tales novels.

And the ancient Hugo, Lord Mallerstang, is a cousin and honorary uncle, and the mad-coolest, to everyone.
- In Diary of a Wimpy Kid, Greg mentions his uncle Charlie several times, claiming that he's his "secret weapon" at Christmas, as he'll get Greg whatever he asks for. Downplayed, though, because he has a tendency to misinterpret Greg's requests; one Christmas, for example, when Greg wanted a Barbie house (because he thought it would make a cool fort for his toy soldiers), he got Greg a Barbie doll instead.
- Uncle Alec is this for Rose and the boys in Eight Cousins and its sequel. He's particularly this to Rose, as he is her legal guardian following the death of her father, and also to his nephew Mac, whom the sequel reveals is his godson.

- In Tales from the Mos Eisley Cantina Greedo's uncle Nok teaches hunting to his nephews and pilots the starship when they narrowly escape from the hired killers who find their refuge.
- The Barrier: Marta has cool relatives on both sides. Her her paternal uncle Álex acts more like an older brother to her at times, providing fake a voiceover for the news or tickling her out of nowhere to amuse her. Her mother's twin sister has slightly less leeway to be fun due to needing to pretend to be her mother and planning to leave town soon for the first half of the series, but adores Marta nonetheless.

When Robert discovers this, he explains that he's only able to do it because he only ever sees the kids for an hour or so at most. Raymond, meanwhile, cares for his children effectively all the time, and shouldn't be ashamed that he lacks the energy to "Play Monster" with them all day.

- Jon Snow clearly views his uncle Benjen Stark this way and adores his uncle, requesting to join his uncle Benjen in the Night's Watch, where he tries to emulate him. The rest of the Stark kids adore their uncle as well.
- Zigzagged by Tyrion, who is very friendly to Tommen and Myrcella, but is not adverse to slapping and insulting (a very deserving) Joffrey when the situation calls for it.

He even admits to Cersei that Tommen and Myrcella's deaths broke his heart because he honestly loved them.

- On Once and Again, Judy is like this for both Grace and Zoe.
- Played with in Snowfall. In the first season, it looks like Jerome fits this role for Franklin, as he helps Franklin gather the manpower and firepower needed to establish his business. In season 2, Franklin gets disillusioned with Jerome after he proves unable to adjust to the rigors of big business, but his worship then goes to his Aunt Louie, who becomes a surrogate mother figure for him after his own mother disowns him.
- Northern Rescue has Aunt Charlie. Her character page on the show website describes her as spending more time dealing with her nephew and nieces' problems than her own.
- Kirby Buckets has an uncle named Leon who is always willing to do "solids" for other people. At first, Leon's solids seemed to work out great for Kirby, as he got him new subscribers for his web channel, a gourmet crab lunch, a girlfriend, a basketball session with NBA superstar Zach LaVine, new sneakers and a car. Unfortunately, Leon's gifts eventually backfired, as they were all either cheap knockoffs (the sneakers, the crab lunch, the subscribers — actually inflated by a bot) or outright stolen (the car). It later turned out that he did all of it on purpose because Kirby's mother specifically told him not to contact him. Needless to say, Kirby was amazed his mother was able to come up with such an elaborate scheme.
- In Jimmy Buffett's song "The Pascagoula Run", he sings about his "black sheep" Uncle Billy, who had made it rich while traveling around the world. When Billy came back home to Mississippi, he immediately went on a 24-hour bar-hopping run to all his old haunts and invited his nephew Jimmy to come along. According to Buffett, this all actually happened back when he was 17.
Billy pulled in in a Jaguar
Red convertible '65

That black sheep uncle of mine
His ship had come in, he was looking to sin
Singing his own song
When he yelled from the drive, my heart came alive
"Jimmy boy come along!"

- In Dragon Age: Origins, the Human Noble Warden is clearly one to their nephew, Oren. This makes it all the more tragic when Oren is killed along with the rest of their family, during Arl Howe's betrayal; the player character's expression is absolutely heartbroken.
- Based on the group dynamics in Dragon Age II, if Varric is the Team Mom and Aveline is the Team Dad, that would make Hawke fill this role. S/he's the one person everyone is willing to go to and is more or less on good terms with everyone.

- Amusingly, the De Santa kids from Grand Theft Auto V see Trevor like this, calling him "Uncle T" and Tracey even hugging him when he shows up at Michael's house.

However, he's also an exceptionally talented hunter, having saved the girls once when they were little and Yang got them lost in the forest, and he was the one who taught Ruby how to wield a scythe (the most dangerous Huntsman weapon, something that's implied to be against school policy). Whenever he's around he dotes on the girls, playing video games with them and telling them stories about his adventures and missions, and the girls absolutely adore him. The only reason he's not around more is that he's busy with his work and because his Semblance is an always-on bad luck power and he doesn't want to risk hurting his nieces with it.

Oh yeah, and he's also a wanted criminal and the shifty owner of a run-down tourist trap. Not the most responsible uncle in the world, but still a good guy. Later, we meet his brother Ford, the local Mad Scientist slash monster hunter, who takes very little time to charm the kids with his various cool inventions, particularly Dipper who idolized him because of his writings long before he knew they were related.
