- ars PARADOXICA is built around this, with the protagonist (Dr. Sally Grissom) being accidentally flung into the 1940s with a Higgs Field Inhibitor.

- This was a primary plot-point in season 3 of Red vs. Blue. During which Church is apparently blown into the past from the bomb that was placed in his gut, while the rest of the members of Red and Blue teams were blown into the future. Church escapes the past by having the computer Gary use his power to create a time machine so that he can go forward in time and stop any of this from ever happening. It turns out that time travel never actually played a role in this though, and that all of Church's experiences in the past were actually him being tortured by Gary (who is really Wyoming's AI Gamma) and the others just being blown away by the blast. Though all of this wasn't put in place until it was retconned by Burnie Burns so that it fit with the later story lines of the Recollection and Project Freelancer.
- Red Panda Adventures:
- In "The World Next Door", a time traveler named Baboon McSmoothie comes from the early forties to the thirties to steal a prototype invention created by Nazi scientist Friedrich von Schlitz. He explains he also came from an alternate timeline precisely to avoid paradox issues in his own. Otherwise stealing the prototype would slow, if not stop, the future work of von Schlitz, give the Allies an advantage, and remove his reason for time traveling in the first place. He enlists the Red Panda's aid with future knowledge that might potentially save the Flying Squirrel's life one day.
- The Red Squirrel is the Terrific Twosome's descendant from the future who was inspired to take up superheroics by stories of her ancestors. She goes to the past when one of her Rogues Gallery starts launching attacks on the past in order to protect the Red Panda and Flying Squirrel. She reappears once more to pose as the Flying Squirrel so Kit can properly prepare for her wedding day, since the Red Squirrel has a vested interest in making sure they get hitched without a hitch.
- "The Honoured Dead" has the Red Panda and Flying Squirrel traveling back in time to retrieve a lost artifact. They utilize time travel because the Red Panda concludes You Already Changed the Past is in effect and the reason the artifact was lost to begin with was because they went back in time to take it.
- "The Chimes at Midnight" feature a pair of time travelers on a mission to elminate the Black Eagle before he can become a superhero. Their information gives them the exact time and place in which he becomes a hero, but the plan ultimately fails because, while their historical records accurately describe the moment the Black Eagle became a hero, they fail to mention that was not the moment he got his powers, which he'd had for a while already.

- The spin-off The Adventures of Grett Binchleaf has even more time travel in it. It went to the extent that after their two first series it was agreed upon by the two hosts that time travel wouldn't be allowed in their third series, with an unspecified punishment each time the rule were to be broken. Trying to get away with still putting time travel then turned into a running gag, resulting in even more of the story being about time travel than before. Cue book 4, and the titular hero escapes his murder by using his magical watch to go an hour back in time multiple times in a row shortly before breaking it upon being killed by a crocodile and being hurtled a thousand years into the past and meeting his nemesis from two different points in time.
