* Happens in the second ''{{Jimmy Neutron}}''/''{{Fairly Oddparents}}'' crossover entitled "Jimmy Timmy Power Hour 2: When Nerds Collide". The obvious solution, since both shows run off the [[RuleofFunny Twin]] [[RuleofCool Rules]], is to throw an [[WhatDoYouMeanItsNotAwesome interdimensional dance party]].

* Brunhilda in ''{{The KAMics}}'' is dating Bobby (Life) from ''LifeAndDeath''.

* ''SomewhereInTime'' hinges on this.

* In the JLA Watchtower universe, Starfire and Hugo. A bit of background: Watchtower was a spin-off of LivejournalRoleplay Lunatic Cafe, which was a multiverse crossroads.

In a plot that crossed both games, an injured Nightwing stumbled into the cafe after an incident on Watchtower. Hugo was the first to intervene and saved Nightwing's life. When Nightwing's friends from Watchtower came to take him home, that universe's version of Starfire [[IfYouKnowWhatIMean took a fancy to Hugo]]. A whirlwind courtship later, "Hugo Wallace Anders" was set up with a new life and identity in Watchtower-verse.

* In the MyLittlePonyFriendshipIsMagic [[{{Rule 63}} genderbending fanfic]] "On a Cross and Arrow", both Fluttershy and Rarity end up falling in love with [[ScrewYourself their male counterparts]] (Butterscotch and Elusive, respectively).

* Happens toward the end of the MyLittlePonyFriendshipIsMagic genderbending fanfic On A Cross And Arrow[sic].

* In {{Farscape}}, John has to choose between Earth and Aeryn. [[spoiler: He chooses Aeryn.]]

** [[spoiler: Actually, one door can be left open, but Lyra and Will choose to stay apart so that the door opened in the world of the dead - so that the ghosts can disintegrate into the rest of the universe instead of just *existing* for the rest of eternity - can stay open. It broke this troper's heart. ]].
