Some Dead Space fanfictions also use a more magical or unexplained form of time travel. It's just a given that time travel is possible, and the focus is more on how the characters deal with being in different times. For instance, a character might suddenly find themselves in the past, witnessing the early days of the Marker's influence. They have to figure out how to use their knowledge of the future to change events, all while trying to survive in a world full of deadly necromorphs.
It could also be due to a scientific experiment gone wrong. A group of survivors might be trying to find a cure in a makeshift lab and accidentally create a time - traveling device. This device could send them to various points in time within the story's timeline. They might use this to go back and save important characters who died early on, which would completely change the course of events in the fanfiction.
Another way time travel works in these fanfictions is through dreams or visions that turn out to be more than just that. A character might have a really vivid dream about the past or future in Riverdale, and then suddenly find themselves actually in that time period. This method allows for a more psychological exploration of the character as they deal with the shock of suddenly being in a different time and having to figure out what's real and what's not.
In some RWBY time travel fanfiction, it might work through the use of a special relic. The relic could have powers that are not fully explored in the original series but in fanfiction are used for time - traveling. For example, it could be activated by a specific combination of Dust or a certain type of Grimm blood.
In some Bridgerton time travel fanfictions, it could be a magical object that enables the time travel. For example, a mysterious locket that transports the wearer to different eras within the Bridgerton world.
In many Narnia time travel fanfictions, it often involves magical objects. For example, a enchanted hourglass might be the key to traveling through time. The sand in the hourglass could have the power to send the character to a specific time in Narnia's past or future.
In Homestuck time travel fanfiction, time travel often involves the use of the various time - related mechanics in the Homestuck universe, like the Green Sun or the Scratch. The Green Sun, for example, could be a portal through which characters can travel to different points in time.
In most DBZ fanfiction, time travel often works through some sort of magical or technological device. For example, in some stories, Bulma creates a time machine similar to the one in the movie 'Back to the Future'. This allows characters to travel to different points in time within the Dragon Ball Z timeline.
In Arrow fanfiction, time travel often works through some sort of magical or technological device. For example, in some fics, there are time - traveling arrows that when shot, can send a character to a different time period.
Well, in a lot of Marvel time travel fanfiction, time travel often involves some sort of portal or gateway. This could be a rip in the fabric of time and space, similar to what we've seen in the movies but with different mechanics. Some fanfics might also have time - traveling as a result of a magical spell gone wrong. Writers like to play around with different concepts to make their stories unique.
In many Kingdom Hearts time travel fanfictions, it often works through the power of the Keyblade. Since the Keyblade has the ability to unlock various things, in fanfic it can sometimes unlock different timelines. For example, Sora might use his Keyblade in a special way to open a portal to the past or future.
