History ComicBook / TimeAndTimeAgain

* AllPowerfulBystander: Superman in the second story, but there he's more of a bystander dealing with more powerful people who are in control of time.

* HaveWeMetYet: Prior to this story, Superman had met Mr. Z before in his own present time and was trapped in the latter's spirit crystal, with Mr. Z claiming that they have met before then. It is in this story where Mr. Z (as General Zeiten) has his first encounter with Superman during World War II, although now because Superman is aware of Mr. Z's spirit crystal, he doesn't fall for being trapped inside it.

* TimeTravel: Superman finds himself traveling uncontrollably between the past and the future, visiting three different incarnations of the Legion of Super-Heroes in the process. His going from one time period to another is caused by his exposure to explosions and energy surges, and also by the Linear Man's manipulations to send him to the point where a cataclysmic event would be able to send Superman back home to his own time. Superman spends a few months trying to get back home to his present time, but his disappearance from the present time occurs only over the course of a single night.

In the story, a mysterious time traveler known as the Linear Man shows up in present-day Metropolis (circa 1991) to bring ComicBook/BoosterGold back to his own proper time period. In the middle of a fight between Linear Man and Booster Gold, Superman intervenes, but in the process he accidentally activates the Linear Man's time-traveling device, causing a hole in space-time to open that sucks Superman in and transports him to the 30th century where he meets with the first three members of the ComicBook/{{Legion of Super-Heroes}}. However, an explosion knocks him back in time to UsefulNotes/WorldWarII, then another puts him back in the 30th century, then another sends him back to the Earth's prehistoric age, and so on.

* MeanwhileInTheFuture: In this case, it's Meanwhile, In The Present Time... as the story cuts between Superman's time-traveling adventures and what's going on in Metropolis during the single night in the present time where Superman was absent. As for what was going on: Lois Lane waiting for Superman to return, Jimmy Olsen's date with Lucy Lane, Perry White talking to his wife and comforting her over the loss of their son, the [=LexCorp=] board members discussing finding Lex Luthor's heir, and Bibbo Bibbowski getting himself drunk in his own bar.

* DomesticAbuser: Clark and Lois encounter his next-door neighbor Gary, a wife abuser, walking down the hall to his apartment, simply saying that he's getting counseling to work out his problems and nothing more after that.

''Time And Time Again'' is a seven-part StoryArc that took place in the ''Franchise/{{Superman}}'' comic book titles in 1991, published by Creator/DCComics. It was written by Dan Jurgens, Roger Stern, and Jerry Ordway, with artwork by Dan Jurgens, Bob [=McLeod=], Jerry Ordway, Brett Breeding, Dennis Janke, Tom Grummett, and Jose Marzan.

* NeverTheSelvesShallMeet: Although Waverider has encountered his younger self as Matthew Ryder in ''Armageddon 2001'' without any problems, discovering that he was the superhero who rescued himself, he was tempted to make himself fully known to both his younger self and his parents, but realized that he couldn't do that because that would disrupt events in the space-time continuum.

* FeedItABomb: The Legion of Super-Heroes try feeding a bomb to the Sun Eater by Wildfire flying straight to the center under his own power, but fails as his containment suit suffers a puncture before he reaches the center of the creature. Two other Legionnaires try to help out Wildfire, but the Sun Eater's energy discharges stop them, and the bomb detonates, causing the three heroes to be propelled from the creature without doing it any damage. With Superman helping on their second try, Wildfire flies to the center of the Sun Eater using only his Legion flight ring and fires all his contained energy at the creature, emptying the containment suit so that Shrinking Violet can turn it into a bomb that would destroy the creature. Superman comes along and flings Shrinking Violet riding inside the containment suit's earpiece to safety before the jerry-rigged bomb explodes and takes out the Sun Eater.

* LeftHanging: The graphic novel of the story doesn't show the aftermath of the Moon's destruction, which was actually followed up in the ''Legion of Super-Heroes'' title.

* AnArmAndALeg: The Linear Man loses a hand as he travels from his own time to the 30th century to resume the countdown to the Earth's moon's destruction.

* BombDisposal: In the first story, the quantum field generator that Superman and the ComicBook/MetalMen try carefully to extract from a pile of wreckage in Metropolis becomes volatile and ready to explode. Superman tries to fly it safely away from Metropolis, but it ends up exploding...though its explosion is stopped in its process by Liri Lee of the Linear Men transporting both the generator and Superman to Vanishing Point to study it. The Linear Men, however, have no interest in stopping the bomb from exploding and killing people in Metropolis, but Waverider, seeing what their technology can do, takes one of their time-travel controls and uses it to transport the generator to the distant past, where it explodes harmlessly without hurting anyone.

* TimePassageBeard: Superman grows one in the prehistoric past, which ends up being removed when he appears in Medieval England during the time of King Arthur.

* AlienGeometries: Vanishing Point, the place where Waverider and Superman first go to in the first story, is a never-ending hallway that somehow causes Superman's telescopic vision to warp around so that he ends up seeing himself and Waverider from behind.

* TimeStandsStill: In both stories, Waverider and Superman alternately experience time standing still in the situations they happen to be in, with Superman in the latter instance changing from Clark Kent to Superman while time is frozen.

* BombDisposal: In the first story, the quantum field generator that Superman and the Metal Men try carefully to extract from a pile of wreckage in Metropolis becomes volatile and ready to explode. Superman tries to fly it safely away from Metropolis, but it ends up exploding...though its explosion is stopped in its process by Liri Lee of the Linear Men transporting both the generator and Superman to Vanishing Point to study it. The Linear Men, however, have no interest in stopping the bomb from exploding and killing people in Metropolis, but Waverider, seeing what their technology can do, takes one of their time-travel controls and uses it to transport the generator to the distant past, where it explodes harmlessly without hurting anyone.
