** The Season 5 finale "The Cutie Remark [[Recap/MyLittlePonyFriendshipIsMagicS5E25TheCutieRemarkPart1 Part 1]] and [[Recap/MyLittlePonyFriendshipIsMagicS5E26TheCutieRemarkPart2 Part 2]]" and ''WesternAnimation/MyLittlePonyEquestriaGirlsFriendshipGames'', although Friendship Games aired several weeks before. During Friendship Games, Sunset Shimmer attempts to contact Princess Twilight Sparkle and ask for her help, but she doesn't respond. Later, after the conflict has already been resolved, Princess Twilight appears and apologizes for not coming sooner, but she was dealing with her own adventure involving time travel, which was then shown in The Cutie Remark.

* On occasion an issue or pair of issues of ''ComicBook/{{Robin|Series}}'' will follow Tim and Stephanie doing their own separate things at the same time, though usually their stories will converge in the end on at least two occasions they remained unaware of what the other was up to.

Compare HyperlinkStory and FlashbackBPlot. Can be related to RashomonStyle. POVSequel is when they decide to do this ''after'' making the original arc. TV episode variant is SynchronousEpisodes.

* ''VideoGame/XenobladeChronicles2'' reveals that [[spoiler:the events of ''VideoGame/{{Xenoblade}}'' happens simultaneously in a different dimension. The Architect is revealed to be Klaus, also known as Zanza in the original game. The difference is that the Architect is the [[TheAtoner good yet sorrowful]] half who wishes for lifeforms to control their own destiny, while Zanza is the [[ForTheEvulz evil]] half that wishes to create a destroy-and-recycle mechanism.]]

** ''Film/BlackWidow2021'' takes place between two scenes in ''Film/CaptainAmericaCivilWar'', after Natasha's final scene and before Steve breaks out his team from the Raft. It also establishes that the gap between the two ''Civil War'' scenes is at least two weeks, meaning that ''Film/BlackPanther2019'' (set one week after an assassination at the beginning of ''Civil War'') also takes place during that span and may overlap with ''Black Widow''.

** ''Film/BlackWidow2021'' takes place at the same time as ''Film/CaptainAmericaCivilWar'' after Natasha's final scene and before Steve breaks out his team from the Raft.

* From the ''VideoGame/TrailsSeries'', the first two games of ''VideoGame/TheLegendOfHeroesTrailsOfColdSteel'' series happen the same time as ''VideoGame/TheLegendOfHeroesZeroNoKiseki'' and its sequel ''Ao no Kiseki''. The main difference is where the stories take place, with the Cold Steel games taking place in the Erebonian Empire, while Zero and Ao take place in Crossbell.

* This is the main concept of the 2000 drama ''Timecode''. The film (presented as four separate unbroken takes in a single screen) follows several different people, including an actress, her lesbian lover, a casting director and his wife as they go about various activities over the course of the day, and occasionally intersect with one or more of the other arcs.

* The first season ''WesternAnimation/JurassicWorldCampCretaceous'' occurs simultaneously with the events of ''Film/JurassicWorld'', while the final episodes of the third season occur alongside the opening sequence of ''Film/JurassicWorldFallenKingdom''.

* The end of Season 1 of ''WesternAnimation/StarWarsResistance'' takes place at the same time as ''Film/TheForceAwakens'' and ''Film/TheLastJedi''. Part of the early plot of Season 2 is that Kaz believes that the Resistance base he was recently told about is still there, since he is unaware of the events of ''Film/TheLastJedi'' (specifically, the base's destruction), and the captain trusts his intel enough to seek the base for refuge and resupply. While they can not resupply at the base, there is still enough debris in orbit to salvage, and to take cover in.

* Some of the events depicted from Spike's perspective in the ''Series/BuffyTheVampireSlayer'' episode "Fool For Love" are shown from Darla's in the ''Series/{{Angel}}'' episode "Darla" (which originally aired back-to-back with it).
** Also done in "Same Time, Same Place", when Willow returns to Sunnydale but is invisible to her friends (and vice versa). All scenes in which She, Buffy, and Xander are in the same place is first shown from one perspective, then the other (usually with a clock or section of third party dialogue to orient the viewer)

** The remakes of ''[[VideoGame/ResidentEvil2Remake Resident Evil 2]]'' and ''[[VideoGame/ResidentEvil3Remake Resident Evil 3]]'' make a few changes, but keep the side-by-side timelines. ''3'' explicitly takes place a day or two either side of ''2'', with a one-day TimeSkip in the middle to allow for the other story to play out. Notably, in ''3'' Carlos blows up a wall in the police station that later becomes an obstacle for Leon and/or Claire in ''2''. There are a few other minor crossovers as well, such as Leon finding a note from Jill in Kendo's Gunshop (this was added to the game in an update to promote the upcoming remake of ''3'').

* Creator/{{Madsthenerdygirl}}'s ''Fanfic/MCURewrites'': ''[[http://archiveofourown.org/works/11613867 New Avengers]]'', ''[[http://archiveofourown.org/works/11613921 Black Widow]]'', and ''[[http://archiveofourown.org/works/11652534 Captain America: Ghosts of HYDRA]]'' all take place at around the same time. The New Avengers (consisting of Sam Wilson/Falcon, James "Rhodey" Rhodes/War Machine, Pietro Maximoff/Quicksilver, Wanda Maximoff/Scarlet Witch and Vision) go up against Sinthea Shmidt/Sin and Viper/Madame Hydra as the two fight for control of the HYDRA organization. Natasha Romanoff/Black Widow is on trial during these events for her past as an assassin from the Red Room which was revealed to the world after she leaked HYDRA and SHIELD to the public in ''Film/CaptainAmericaTheWinterSoldier'' and Clint Barton/Hawkeye is testifying at Natasha's trial. Steve Rogers/Captain America has gone on a mission to help his friend, James "Bucky" Barnes/The Winter Soldier and free him from HYDRA's control and as a result the New Avengers do not have him to lead them and he does not have anyone helping him until Maria Hill sends Sharon Carter/Agent 13 to assist Steve.

* From the ''VideoGame/TrailsSeries'', the first two games of ''VideoGame/TheLegendOfHeroesTrailsOfColdSteel'' series happen the same time as ''VideoGame/ZeroNoKiseki'' and its sequel ''Ao no Kiseki''. The main difference is where the stories take place, with the Cold Steel games taking place in the Erebonian Empire, while Zero and Ao take place in Crossbell.

* This happens in the ''{{Series/Smallville}}'' episode "Promise" (season 6, episode 16), which shows the same day from the perspectives of Clark, Lex and Lana, all of which converge near the end of the episode.

* As you expect, taking in consideration [[VideoGame/PaperMarioTheThousandYearDoor the source]], ''FanFic/PaperMarioX 2'' and ''Paper Luigi X'' take place at the same time. Team Mario and Team Luigi even meet each other at various points (not to mention Team Luigi meeting with Team BEG at one point). [[spoiler:Team Luigi even gives support to Team Mario in {{the climax}} of ''Paper Mario X 2''.]]

* ''Post Nuptials'', first story in FanFic/TheNuptialverse: Except for the first, second-to-last, and last chapters, every chapter happens at roughly the same time (this allows us to get a sneak peek of Spike's chapter in Pinkie's).

* The ''FanFic/RainbowDoubleDashsLunaverse'' stories ''[[http://www.fimfiction.net/story/26552/Family-Matters Family Matters]]'' and ''[[http://www.fimfiction.net/story/33556/Helping...Hands%3F Helping…Hands?]]'' occur around the same time, or at least share a scene where Dinky asks Trixie for help while she has problems of her own.
* ''FanFic/{{Horseshoes and Hand Grenades}}'' has at least ''three'' different stories trying to make sense as to what's going on and they all make references to one another. Most notably, while the majority of ''Horseshoes'' takes place in Kyoto, we have three different sets of protagonists doing different things. ''Month of Sundays'' has many minor Amanogawa High characters getting involved with [[Series/KamenRiderDouble Foundation X]]. ''[=SplitxEnd=]'' has Yayoi researching what caused Horseshoes to go crazy and subsequently meeting up with [[Series/KamenRiderWizard Haruto Souma]], and ''Wheel of Fortune'' is based around Mei's struggles by interpreting fate of different characters and uncovering the story behind [[TheHeavy Yamada Tatsumori]].
* [[FanFic/RainboomsAndRoyalty The Dashverse]]: ''Hot Heads, Cold Hearts, and Nerves of Steel'' briefly follows two different {{Story Arc}}s occurring at the same time -- the Mane Six, Shining Armor, and Cadence on their way to the Crystal Empire to save the foals kidnapped by King Sombra, and Pipsqueak, Alula, and Dinky Doo (later joined by Zecora) in the tunnels underneath Equestria and the Empire. The two groups eventually meet up just before the climax.
* ''FanFic/JusticeLeagueOfEquestria'': ''The Princess of Themyscira'' and ''In Brightest Day, In Blackest Night'' take place at the same time as the second half of ''Mare of Steel''.
* ''[[FanFic/MLPNextGenerationLoveConquersAllAvariceTakesItAll MLP Next Generation: Love Conquers All! Avarice Takes It All!]]'' is split along two plotlines running alongside each other -- Anthea learning to use the Star Sapphire ring while she and Twilight investigate griffon incursions into minotaur territory, and Nidra dealing with the temptations of the Orange ring that's chosen her as its bearer.

* ''Fanfic/ThePrayerWarriors''

* ''{{VideoGame/Pikmin 3}}'' starts this way, since the S.S. Drake malfunctions shortly before landing causing its crew to be split up. We start by seeing the first day of exploration from Charlie's point of view, then we switch to Alph's point of view as he attempts to locate the S.S. Drake.

* From the ''VideoGame/KisekiSeries'', the first two games of ''VideoGame/TheLegendOfHeroesTrailsOfColdSteel'' series happen the same time as ''VideoGame/ZeroNoKiseki'' and its sequel ''Ao no Kiseki''. The main difference is where the stories take place, with the Cold Steel games taking place in the Erebonian Empire, while Zero and Ao take place in Crossbell.
* ''{{VideoGame/TrinityUniverse}}'' does this, with the Demon King (Kanata) and Valkyrie (Rizelia) arcs. Their paths do intersect at various chapters, and eventually both sides will join together. You have to play both arcs to piece everything together, which will lead you to the game's True Ending.

* The end of Season 1 of ''WesternAmination/StarWarsResistance'' takes place at the same time as ''Film/TheForceAwakens'' and ''Film/TheLastJedi''. Part of the early plot of Season 2 is that Kaz believes that the Resistance base he was recently told about is still there, since he is unaware of the events of ''Film/TheLastJedi'' (specifically, the base's destruction), and the captain trusts his intel enough to seek the base for refuge and resupply. While they can not resupply at the base, there is still enough debris in orbit to salvage, and to take cover in.

* ''VideoGame/FrontMission 4'' is played in chapters alternating between two different teams of pilots in completely different locations. The story occurs chronologically, but the characters don't meet until the very final chapter.

* ''VisualNovel/{{Remember11}}'' uses this, with the entire story being told first from the perspective of Kokoro, and then restarting from the beginning, seen through Satoru's eyes.
