Sibling Switch Squick
Let's say the main character's name is Alice
. She has a brother named Bob. The creator writes a new series with a totally new character, also named Alice. Alice's love interest in the story just happens to be named Bob (or look exactly like him, or act like him), and even though they're new characters, it still causes a Squick
Compare and contrast Brother-Sister Incest
, which don't even bother
with the Expy
- Lana Lang and Superboy, based on one cover on Superdickery.com, were siblings in one story, when in almost every other, she's his love interest.
- In the original Italian Martin Mystere comics, Diana is Martin's love interest (and later wife), but in the French Martin Mystery cartoons she's his stepsister. Granted, they're Not Blood Siblings, but it's still pretty unnerving.
- Stephen King's Desperation and The Regulators, depending on which you read first. Either way, the Carver family from one version of the story reverts who are siblings and who is married. In other words, David and Kirsten/Pie would be brother and sister in Desperation, and their parents Ellen and Ralph, but in The Regulators, they're married, with Ellen and Ralph now their children.
- The relationship between Mega Man and Roll differs from series to series. She is treated like his younger sister in the original series, a protective older sister in Mega Man Legends, and a love interest in Battle Network.
- In the Battle Network series, Rock is his human Operator's dead twin brother. This relationship does not exist in the anime. The two are shipped. It is about as squicky as it sounds.
- If you read Roll's Diary at the end of Mega Man Legends 2, Roll admits that she's in love with Mega Man.
- Due to the nature of the Legend of Zelda mythos, with several generations of Links and Zeldas with different relationships, this comes into play in installments when their relationship seems more romantic, while in others it comes across as familial (especially due to a translation of the SNES game making gamers believe she is Link's sister.)
- The Sims pulled this in reverse when The Sims 2 was released, with the new Family Tree feature which revealed that Bella Goth and Michael Bachelor were brother and sister - squicking out any player who'd had Bella leave her husband and marry Michael in The Sims 1.
- There's also Fran and Freddie Foofaraw in the first Sims game for console, who look very alike and are usually taken to be brother and sister... except for the fact that Fran's bio in the official game guide refers to Freddie as her "hunk". This sort of thing happened a lot in the first generation of Sims games due to the lack of formal family trees.
- The trope gets Inverted a couple of times in Veronaville, the town in The Sims 2 which is loosely based on a number of Shakespeare plays: Beatrice and Benedick are named after romantic leads but are twin siblings in the game, while Romeo and Mercutio go from being best friends with lots of Ho Yay undertones to brothers.
- Fire Emblem Awakening and Fire Emblem Fates both have this for the same reason. In both games, most of the children are tied to one of their parents: mothers in Awakening, fathers in Fates. Both games also have a child (or two, depending on the sex of the Player Character who has a tied child as well) that is tied to a different-sexed parent than all the others, meaning that they can get a sibling in the form of the child tied to their other parent. The children can also be married to each other as long as they are not siblings. Part of the Replay Value of these games in the possibility to try different marriages for different parent characters, which makes one playthrough's siblings into another playthrough's potential spouses.
- It's a bit disconcerting to start on Safe Havens because you're a Kevin & Kell fan and discover that the geneticist with big hair is in a relationship with the dyslexic sports star who always wears sunglasses. The two K&K characters by those descriptions are only step-siblings, but still.
- Referenced in Roomies! with Joe's reaction to a change in Walt Disney's Hansel and Gretel.
- In the comics Minnie Mouse has an Uncle Mortimer Mouse, but in the cartoons Mickey's rival for her affections is an obnoxious cretin also named Mortimer Mouse (he's called Montmorency Rodent in the comics). In Mickey's Once Upon a Christmas, Mortimer Mouse is the name of Minnie's boss. What's more confusing is that Walt originally wanted to name Mickey "Mortimer", and that in the comics Mickey has a nephew named Morty, short for (what else?) Mortimer. No switching with siblings here...just everybody else.
- In the original Marvel comics, Silver Samurai and Mariko Yashida were half-siblings. Their Wolverine and the X-Men versions are a married couple.
- In the original Superfriends cartoons, Marvin and Wendy were apparently just friends. When they got adapted into the comics, they became fraternal twins. In Young Justice, they're back to being friends, and have a Relationship Upgrade by the finale.
- Meta example in Total Drama Presents: The Ridonculous Race—the villains, Josee and Jacques, are The Straight Will And Grace (...well, depending on how you interpret Jacques), but have the right level of bickering and legitimate intimacy ("mon petite chou") that a lot of fans started to pair them. Eventually, Word of God revealed that they were originally planned to be siblings. This has not necessarily stopped anyone, though, since they're clearly not related in the version that aired.
- Inverted with X-Men: Evolution. In the comics, Kurt had an adoptive sister named Amanda Sefton whom he dated for a while. In the show, a fairly In-Name-Only version of Amanda is a Love Interest but not related to him in any way.
