Time portals are doorways in time, employed in various fiction genres, especially science fiction and fantasy, to transport characters to the past or future.
They differ from time machines in being a permanent or semi-permanent fixture linking specific points in time, and thus are an especially useful plot device when the plot involves characters moving many times back and forth.
Time portals can be represented as vortices of energy, which allow matter to travel from one point in time to another by passing through the portal, or may appear as an ordinary doorway.
In most films, time portals are used to take a group of people or a single person back in time. The most popular of all time travels would be traveling back to the time of the dinosaurs. In some films time portals can also be set as a hazard, for example, they can begin to go haywire which makes them accidentally transport something or someone from a different time to the present; again the most popular is a dinosaur being accidentally brought into the present world.

Time portals are also the original mode of time travel in the SNES game Chrono Trigger . There are quite a few of them found throughout the game and seem to be activated by the use of a "key" made by Lucca.

Suspended animation in fiction refers to the temporary cessation of life processes experienced by fictional characters, followed by their subsequent revival. This process is commonly employed as a plot device in science fiction narratives. It is frequently utilized to transport a character from the past to the future or to facilitate interstellar space travel, which necessitates an extended journey for months or years. In addition to accomplishing the character's primary objective in the future, they often encounter the unfamiliarity of a new world, which may bear only faint resemblance to their previous surroundings. On occasion, a character is portrayed as possessing skills or abilities that have become lost to society during their period of suspension, enabling them to assume a heroic role in their new temporal setting.
