  • General Takeda's daughter, Katsura, is a classmate of the Ganba Team, not that she knows it.
  • Tsutomu Kojima, The Smart Guy, has a cousin who is part of the Saurers, Takako "Professor" Kojima, which if you can't tell by her nickname, is The Smart Girl of the group.

• Negima! Magister Negi Magi: Eishun Konoe is revealed to be a cousin of Tsuruko and Makoto from Love Hina. While a lot of other characters could be considered expies from other Ken Akamatsu works, this one really solidified the Akamatsuverse.
• Skull Man: The ending of the 2007 anime reveals that the main character is actually the father of the title character from Cyborg 009.

• In the 2000 AD strip Portals and Black Goo: The Night Shift about a delivery driver to the Monster Mash, one of his regulars is an immortal, but somewhat down-on-his-luck, sorcerer called Magister Dain, who frequently mentions his more successful brother, who has a castle. The final chapter reveals that this is Cursitor Doom, from the strip of the same name in Smash!

• The League of Extraordinary Gentlemen, being a Massive Multiplayer Crossover comic, frequently reveals characters from the various works it adapts to be relatives. Especially if they happen to share the same surname:

  • Both being spies, Tara King from The Avengers (1960s) is now the sister of Jason King.
  • Captain Universe's alter-ego, Jim Logan is now a brother to Jet-Ace Logan. Short-lived superhero and Captain Space, Defender of Earth! from British comic strips respectively.

  • In the spin off Nemo: Heart of Ice, Hugo Hercules mentions fathering a child in a town called Cactusville, and is later seen eating a pie made from an entire cow, with horns and tail sticking out. All of which implies he's the father of The Dandy (1937)'s Desperate Dan.
• Shazam!: The Secret of the Freeman Brothers" in World's Finest #280 reveals that Quality Comics character Kid Eternity lives on Earth-S with the Fawcett characters and has the real name Kit Freeman; he's Freddy Freeman/Captain Marvel Jr's long-lost brother. This was probably undone by the Crisis, or at least glossed over in Eternity's Vertigo Comics book.

  • Shrek: The Musical reveals that Farquaad's father was Grumpy from Snow White And The Seven Dwarves, which actually explains a lot.

The central relationship is that Tarzan and Doc Savage are cousins, grandsons of the Duke of Holdernesse from the Sherlock Holmes story "The Adventure of the Priory School". (Holdernesse is said to be Watson's name for the title Edgar Rice Burroughs called Greystoke, while Doc's father Clark Savage Sr is the illegitimate son that Watson called James Wilder; Farmer calls him James Clarke Wildman.)
• The Sherlock Holmes novel The Spider's Web by Philip Purser-Hallard is a Massive Multiplayer Crossover with many Oscar Wilde works. Wilde's reusing of names is explained by saying the title character of Lady Windermere's Fan is the neice-by-marriage of the Lady Windermere who appears in "Lord Arthur Savile's Crime". In addition, Cecily from The Importance of Being Earnest is secretly the illegitimate daughter of Lord Illingworth from A Woman of No Importance.

• Friends: Phoebe is the twin sister of Ursula from Mad About You. Both are played by Lisa Kudrow.

• 9-1-1: Lone Star: In the episode "Hold The Line", a crossover with parent series 9-1-1, Mateo asks the LA crew if they know his cousin Marvin, a minor character from 9-1-1's second season. This doubles as a reference to the fact that Mateo and Marvin are played by the same actor.
• Once Upon a Time (2011) brings together multiple characters from classic Western fairytales and Disney animated films ^note  and also liberally applies Composite Character, with an infamously twisted family tree of relationships:
  • With the Season 2 reveal that Rumplestiltskin's son is Henry's father, Rumplestiltskin is "in-laws" ^note  with Snow White and Prince Charming, Henry's biological grandparents, and the Evil Queen, Snow White's stepmother and Henry's adoptive mother. Once Belle from Beauty and the Beast marries Rumple (who is the same person as the Beast, as well as the Crocodile from Peter Pan) and Snow White's daughter marries Captain Hook, the web of in-laws gets... extensive.

    Charming: It's a good thing we don't have Thanksgiving in our land because that dinner would suck.

  • The Evil Queen's mother would go on to become Wonderland's Queen of Hearts, and was also the Miller's Daughter from the Rumplestiltskin fairytale. The Wicked Witch of the West is later revealed to be the half-sister of the Evil Queen via the Queen of Hearts.
  • Peter Pan is Rumplestiltskin's father (though he didn't really become Pan until after Rumple was born).

• Fate/Grand Order:
  • Though they lived centuries apart in their original lives, Arjuna and Minamoto no Raikou are half siblings. Arjuna's father is the Hindu God Indra and Raikou's father is the Shinto God Gozu Tennō, but in the Nasuverse, the two gods are one and the same.

• HoloFunk 5.0: hololive idols Amane Kanata and Tokoyami Towa are revealed in sidestories and background details to be the first cousin and younger sister of Friday Night Funkin' protagonists Boyfriend and Girlfriend respectively.

• Poker Night 2: One extended conversation has Ash Williams wonder whatever happened to Sheila after the events of Army of Darkness.
