Triple Shifter

Anyone whose description is "Normal Job By Day, Crimefighter by Night!"

So we'll see them doing stuff during day and night—constantly. Don't they ever sleep? The actual physical consequences are rarely taken seriously. There may be an episode or two with a teacher or employer being annoyed that the Triple Shifter is dozing off; rarely anything else happens. Night is naturally the time for saving the world when you Wake Up, Go to School, Save the World.

Of course, one could assume that Evil doesn't strike every night. But it sure seems that way. Also, if it is shown as a constant issue of exhaustion, it will usually be school or work that suffers, as opposed to their night-time adventures. If this is averted it's a case of Plot-Powered Stamina.

Has nothing to do with shapeshifting between three different forms.

Anime and Manga

 * Many a Magical Girl does this; curiously the matter of sleep is only an personality issue. One may be a Heavy Sleeper or always Late for School; but that's more about them and less about fighting monsters in the middle of the night. Her companions sleep as little as she does, and don't seem to have any problems.
 * The matter of sleep was actually addressed in the third episode of Magical Girl Lyrical Nanoha's first season, with Yuuno telling Nanoha to take a break since she's exhausting herself. Naturally, that led to her missing a Jewel Seed that proceeded to damage her town. Also, in the second season, the Wolkenritter go out searching for Linker Cores at night, because they spend their days with Hayate, who is not supposed to know about their nightly trips. Justified by them being artificial constructs who might not need sleep at all.
 * And then there's Teana, who puts herself through a rigorous training regimen (in addition to her regular training which in and of itself is very demanding) resulting in only sleeping four hours a night. At the end of it she's so exhausted her body needs 30+ hours of sleep to recover.
 * As the Sailor Moon English Expository Theme Song tells us, the titular heroine is "Fighting evil by moonlight, Ear Worm winning love by daylight..." Even before becoming a warrior of love, she was having problems getting to school on time, but somehow being Sailor Moon doesn't compound it at all.
 * Played with in Cardcaptor Sakura. Though catching magical and mischievous cards shouldn't be particularly exhausting (considering she catches 52 of them over the course of roughly 15 months; it's not even a weekly occurrence), transforming them is quite draining to her limited magic. (As well as using the Time and Return Cards, which even knock Syaoran for a loop!) Because of this, Sakura tends to doze off during class, or immediately after said transformation. She will also occasionally fall asleep in class for the purpose of having a prophetic dream (which tends to require the dreamer to be asleep at the time).
 * plays this trope far more dramatically.
 * In a completely mundane instance, Sakura was shown to be dozing off in class all week long. Syaoran and Tomoyo thought she was transforming cards behind their backs. She was actually.
 * Fresh Pretty Cure actually showed the end result of an action such as this - Love, Miki and Buki actually got themselves hospitalized because they pushed themselves between dance practice, school and being Pretty Cure.
 * Lelouch/Zero from Code Geass. In one episode, after schoolgirl/terrorist Kallen is publicly embarrassed due to nodding off in class, Rivalz suggests she take lessons from Lelouch, who's the undisputed master of sleeping through class without getting caught, napping through about half the school day on average. He still manages to pull a straight-B report card and somehow maintain his Rich Idiot With No Day Job public persona while secretly working to overthrow the government nights and weekends.
 * Sousuke of Full Metal Panic!, due to the combined stresses of completing schoolwork and typing up reports for his superiors (not having slept for four days in the process) collapses with a fever in an episode of Fumoffu.
 * In the second novel, he falls asleep in class with his eyes open after having spent the night dealing with a Humongous Mecha rampaging through Tokyo.
 * The plot of TSR is centered around the fact that Sousuke can't keep up his Wake Up, Go to School, Save the World routine as his presence is needed to pilot his organization's only Super Robot Genre.
 * In the later novels, his sleeping habits are shown a bit more... and they're very unhealthy. Apparently, he got into the habit of always sleeping under the bed, with his eyes open, and is always holding a weapon of some sort. During the time when he sleeps, he also has nightmares of his mother dying, and actually counts himself lucky when he gets six whole whopping hours of sleep that day (after wandering around until he passed out from fatigue). It definitely doesn't bode well for his life expectancy.
 * Kekkaishi's Yoshimori is constantly falling asleep in class, since he's in school during the day and hunts Ayakashi during the night. His 'breakfast' is often coffee-flavored milk.
 * Oddly enough, Tokine seems to have the same schedule, but she's depicted as a model student.
 * That's because Yoshimori usually goes all out, exerting his energy while Tokine thinks things through and only does what she must. Yoshi-mori outright exhausts himself.
 * The girls get hit on both ends in Demashita! Powerpuff Girls Z. When they have to fight at night they're look exhausted the next day, and they're show having to take a supplementary class. On one occaison they actually have to leave the professor to fight monsters while they take their school finals.

Comic Books

 * Batman is of course the Trope Codifier. In some continuities it's explained that he doesn't sleep but rather engages in a 30-minute trance every day that "gives the equivalent of a six-hour sleep."
 * In other continuities, no one bats an eye [pun unintended] because he occasionally makes a brief but memorable evening appearance as Millionaire Playboy Bruce Wayne, carousing the night away with beautiful women on his arms. So he's assumed to be sleeping all day thereafter, as a Rich Idiot With No Day Job.
 * After the battle seen early on in The Dark Knight, Bruce Wayne is seen sleeping at the table during a board meeting at Wayne Enterprises the next day.
 * On the other hand, Terry, Bruce's successor as Batman in Batman Beyond, is regularly shown struggling to balance the demands of his daytime life with his responsibilities as Batman, and frequently his daytime life suffers as a result: he falls asleep in class and has poor grades, and both his mother and his girlfriend are often on his case about his apparent lack of reliability.
 * Batman's first apprentice, Nightwing, is allowed to be a little more human, and when he's forced to go without sleep, he suffers for it.
 * In one episode of Justice League, Batman hasn't slept for three nights straight...as they fight the Villain of the Week whose power is being able to attack you in your sleep. At the end of the episode, after he and J'onn save everyone, he's seen slumped over in a chair in the Watchtower's infirmary, snoring.
 * Also gave us the priceless moment when he barges into a Starbucks to order said supercaffeinated beverage. For a moment it looks like he is going to have to wait in line but everyone gets out of his way and lets him cut to the front.
 * And cranking up the radio in the Batmobile, along with shattering the windshield to get a cool breeze going.
 * The first episode of The Batman has Bruce Wayne commenting to Alfred that even though it's been 3 years since he donned the outfit, he still can't get used to being tired during the day.
 * Of DC's holy trinity, two members could conceivably justify not needing any sleep... yet it's the third that does all his crimefighting at night.
 * In the DCAU, at least, Superman has to sleep - such as in the aforementioned episode of Justice League.
 * One novelization has Superman comment that he was able to go several days at a time without sleep back in his college days, but now that he's getting older, he just goes to pieces if he doesn't get a full one hour of sleep per night. So he does need to sleep, just, not very much. In fact, some continuities appear to use that to explain how he finished college and had time to go walk the earth. He didn't sleep and studied instead!
 * At least one issue of the Silver Age comics (or Modern Age, it was pretty close to the time of Crisis on Infinite Earths ) focused on him trying to find a time to at least nap - but being denied this by needing to be at Jason Todd's school for a meeting, a corporate thingy, a date, and then a Batman - required emergency. Eventually he falls asleep on the back of a gargoyle as the sun rises.
 * Tim Drake, the third Robin, doesn't appear to have had time to sleep in 5 years. He spent his days at school, his evenings socialising, his nights as Robin and his weekends at the Teen Titans - who train and fight supervillains and cults and hordes of their own members who've turned evil day and night. As Red Robin, he simply cut out his friends and family (most of whom had died), not to mention school, to superheroing and sleeping. And brooding. A lot of brooding, about how many people he knows who are dead (a lot) and how many of those are his fault (perhaps half).
 * In the old days of Batman (The old-old days, but not the original days, wow. Retcons make tenses fun) this was a little more justified. He ended his activities before 4am, and typically wouldn't start them until 11pm-12pm, only working for a four hour block every night. Assuming he's one of those people who can get by on 4 hours sleep a day with occasional longer periods asleep then his schedule would be entirely manageable (back at Wayne Manor by 4:30am, asleep immediately, awake again at 8:30am ready for the day. Also, it doesn't seem in the early issues like he's doing it every night, maybe only three or four nights out of the week, which for a man in the his mid-20s wouldn't be too outlandish. It's only later when he starts working at Wayne Enterprises from 7am to 10pm, changing into his costume at night and going out for a full night of crime fighting before returning in a new suit the next day.
 * Spider-Man also does this, though he isn't as lucky as Batman and is constantly harassed as Peter Parker for being sleepy.
 * Spiderman 2 deals with this directly, as Peter finds his daily life falling apart so badly that he unconsciously shuts off his powers just to get a break. Once he regains his confidence and gets the girl, though, all his problems with sleep deprivation and scheduling conflicts vanish again.
 * Daredevil is perhaps a still more brazen example of this trope. While most other heroes have at least some sort of justification for it (Bruce Wayne has the luxury of sleeping through most of his work days, Peter Parker might not need as much sleep as a normal human, and Superman almost surely doesn't need any sleep at all), Matt Murdock has no superhuman stamina, and a very demanding day job as a defense attorney. One can only imagine the hundreds of mistrials that'd result if the world ever found out that he's apparently been representing his clients in a groggy, sleep-deprived daze.
 * He usually wins his cases, seeing as he's known as one of the best defense attorneys in Marvel's version of the Big Apple. Which makes it even more of a brazen example.
 * Paperinik, the superhero identity of Donald Duck whose authors generally know how ridiculous they're being, gets off easy: his regular identity is a layabout loser who arouses no suspicion by catching "Z"s during the day.
 * The hero of the comic Hero By Night. He's a Legacy Character with a Magic Ring, which grants him superhuman vitality. This translates into enhanced physical abilities and toughness, but also a removal of the need to sleep. He does need to meditate, as his predecessor did, to stay sane with no ability to dream.
 * This is mentioned in Watchmen when Rorschach notes he hasn't slept in days and that he is getting too tired to think straight. He also chides himself for falling asleep without removing his mask. The guy is a bit crazy and has immersed himself in his superhero persona so deeply that he seems to forget the need to rest every now and then.

Fan Works

 * Ultimate SpiderWoman: Change With the Light: Mary Jane Watson starts to suffer from this trope when she becomes increasingly unable to juggle her acting career, her waitressing job, her mother's therapy bills, her superhero career, and her failing grades. She's increasingly stressed out due to a lack of sleep, and when a particularly Unsatisfiable Customer becomes too much of a pain in the neck, Mary Jane finally snaps.

Film
"Zed: You get used to it. Or suffer a psychotic episode."
 * The Dark Knight shows that Batman's constant triple shifting are wearing him down and making him a little sloppy at the beginning of the movie. He also complains of exhaustion at least once.
 * At one point in Men in Black, Jay actually asks Zed whether they ever sleep. Apparently, the organisation works to an alien schedule of a 37 hour day. The lack of sleep is implied to be offset by drinking copious amounts of coffee.


 * Theoretically possible, and perhaps even preferable. A couple of studies done where people are locked in rooms with no sense of time show them adapting naturally to anything from a 20-30 hour day. It's still a little short of the Men in Black day but if they were also extending their sleep cycles or taking multiple naps(it's not saying they're awake for 37 hours, just that the day is 37 hours long) then they probably could adapt.
 * By the beginning of Spider Man II, Peter is falling asleep in his college classes, missing some, and turning assignments in late due to this. Dr. Connors considers Peter to be another trope, and is on the brink of failing him.

Literature

 * Averted in A Clockwork Orange when Alex skips school and stays home the day after a night out with his droogs to sleep it off. And, well, by the fact that he's a sociopath by night instead of a hero by night.
 * A common problem for the Animorphs. They often casually mention failed tests or sleeping in class due to night-time missions. Sometimes they just get the Chee to double for them when a mission requires them during odd hours. In one book Jake mentions that he's managed to get by on random power napping whenever he has twenty minutes or so free.

Live-Action TV

 * Everyone on 24, it seems, mandated by the format of the show. Jack Bauer only gets to sleep between seasons. This may be more justified than other examples as it is only one long day, usually with a few year's gaps between. With caffeine and andrenaline, most people can function on one missed night of sleep and everyone aside from Jack has opportunities to stop and catch their breath at some point. Jack usually shows the toll by the end of the day.
 * In a Danish parody, Jack spends the first 12 episodes sleeping. The dramatic highlight comes along in episode 13, were he is finally awakened by the mailman's arrival, only to receive a huge telephone bill.
 * Buffy the Vampire Slayer. Although she often complains about it, and it seems that most of her bad-guy-fighting is done in the evenings rather than smack in the middle of the night. It's assumed by many that "getting by with very little sleep" is a minor Slayer ability except, of course, when the plot requires her to have a prophetic dream. Her friends actually do have problems matching her schedule, they mostly seem to go to bed once the club closes.
 * "I have at least three lives right now, none of which mesh. It's like oil and water and... a third unmeshable thing."
 * Dexter Morgan seems to ignore this problem entirely, with no apparent problems. By day, he's a skilled forensic scientist, and have never been shown to doze off at work. In the afternoons and evenings, he spends time with his girlfriend/wife and her kids, or go bowling with the guys from work. At night, he stalks people he suspects of being murderers, and once he is sure, abducts them, kills them, and cuts them into little pieces he can dump in the sea. Sleep? Optional.
 * It is actually lampshaded in a couple of episodes of the second season, when Dexter is considering turning himself in (which would almost certainly ensure that he spends the rest of his life in prison), he comments "It might be fun to start sleeping again." Towards the end of the arc, however, with the difficulties resolved, he just shrugs it off as he prepares for another triple-shift day. "I can't believe I was going to give up all of this for SLEEP..."
 * The fourth season starts out with him completely exhausted, to the point of dozing off while driving away from a kill. Things continue to spiral out of control from there, but the lack of sleep is noted.
 * The same is true, but even more exaggerated for the Ice Truck Killer.

Tabletop Games

 * Old World of Darkness games with living protagonists (Werewolf, Mage, Hunter, Changeling, etc.) are set up like this, with the heroes balancing their supernatural lives with mundane jobs and relationships. Werewolves born as wolves don't really have this problem, but it's a wonder everyone else can get up for work after spending all last night fighting the Sabbat, Technocracy, and/or Black Spiral Dancers, let alone hiding/explaining away any wounds from such a battle. However, creative Storytellers can make this part of the challenge. On the other hand, werewolf society generally puts the money-earning burden mostly on the homid Kinfolk (werewolves' human relatives) so the Garou don't have this problem and don't have to worry about frenzying and mauling their coworkers.
 * The lack of Metaplot-mandated constant, large-scale warfare in the New World of Darkness means this is less of a problem. The danger of regular life being intruded upon by the supernatural is still a possibility, and one of the Sourcebooks notes that being more human than the other supernaturals is something that can be used against mages.
 * The Space Marines of Warhammer 40k sleep one hour per 24-hour day. They use this period to recharge, as operating for one or more consecutive 24-hour periods, while possible, can cause serious fatigue and impair their combat ability. Supersoldiers much.
 * They can also switch off a half of their brains at a time, keeping themselves awake while they sleep.
 * Though the daily rituals of a space marine as posted on the Lexicanum wiki allocate four hours for sleep, not one.

Video Games

 * Video game example: Persona 3 features a group of (mostly) high-school students who can only fight the world-threatening evil during a slice of non-time accessed at midnight. The resulting exhaustion is a status effect that puts a massive crimp in a Tired character's performance. The status effect lasts into the next day as well, can degrade further into being Sick [even worse than tired], which further interferes with classwork for the day. Bit of an aversion compared to the usual "Doze off in class, feel 100%".
 * Persona 4 has the dungeon-exploration take place during the day, avoiding this (and if you do it you can't do anything that night out of exhaustion). But the characters seem to have no trouble staying up until midnight several nights in a row to watch the Midnight Channel.
 * They could've easily take a nap and set the timer to wake them up in time, or sleep in until the very last minute the next morning.
 * Gordon Freeman in Half-Life 2. Supposing he arrives in City 17 in the late afternoon, he spends the first night fighting in Ravenholm, the next day fighting and driving, the second night fighting in Nova Prospekt, and fights again in the late afternoon of the third day (from his viewpoint). Then come the extensions, which may or may not have allowed him to sleep (or be knocked unconscious) in-between. Of course, he had just slept for twenty years, and maybe those medkits contain Food Pills. And maybe caffeine...
 * There's a one-week break at the start of Anti-Citizen One, and he's in stasis again by the end of the story, giving him unknown hours of sleep between the end of Half-Life 2 and the start of Episode 1. The same applies to the gap between Episode 1 and 2; it appears the same again will be true of Episodes 2 and 3. He does manage to go for three whole days without sleep, but the episodes are a different affair.
 * Doesn't exactly fit with the crime fighting description, but earlier Harvest Moon games allowed you to stay up all night working, only being forced to "sleep" at the hour when you wake up every day so that you can have breakfast. Loss of stamina could be easily remedied by eating food or bathing in the hot spring, so it was common to go the whole game without sleeping for any reason other than skipping days to reach a particular event. This has been averted in later games however by the inclusion of sicknesses from going without sleep for too long and the difficulty in increasing stamina, not to mention the crippling effect that low stamina will have on your character, making it near impossible to perform any task worth staying up for.
 * Part of the game mechanics of Twilight Heroes - the justification for limiting the number of turns your character can play per day is that they have a day job; caffeine and sugar allow you to stay up later each night.

Web Comics
"In a perfect world, I'd be given enough time to wrap up one emergency before the next one starts."
 * In Girl Genius some sort of an "Ancient Skifandrian Technique" allows that. Hardly ever taught to outsiders. And the Baron taught it to Gil.
 * Axe Cop only sleeps 2 minutes a night, allowing him to fight crime during the day and night.
 * Mr. Raibert from Freefall is habitually overworked, as one of the few competent bosses in Ecosystems Unlimited, which means his participation in most troubleshooting that requires decision or authorization on high level, when his corporation branch does the bulk of job on terraforming a planet and they are at the point when consequences of their early jury-rigging began to really catch up with them. And since the assistants don't keep up with his pace, the problem keeps perpetuating itself.


 * He runs on [[Klatchian Coffee|energy drinks] and "his regular" pizza recipe is rather unconventional.

Web Original

 * A genuine problem for Sailor Nothing, of course.
 * Less Than Three Comics' Brat Pack, especially Belle.

Western Animation

 * Danny Phantom used this as a Running Gag in at least one episode.
 * The Powerpuff Girls used this as a plot point once, as the Girls started sleeping in class after fighting crime all night. Miss Keane convinced Professor Utonium to establish a curfew, which results in the City of Townsville being overrun and nearly destroyed by villains deciding to take advantage of it.
 * Darkwing Duck used to have no problems with this—he did his crimefighting thing at night and slept during the day. Now that he has to be a single dad during the day, one has to wonder when he gets to sleep. Although if you've seen seen Goslyn in action, it's obvious parental supervision is a sometimes thing.
 * In the new comics, it's revealed that SHUSH gave Darkwing a pension.
 * In An American Tail 2: Fievel Goes West, Fievel doesn't get any chance to sleep in the two and half days between the time he falls off the train to the end of the movie.
 * Became a point of contention between Bruce and Terry in Batman Beyond. The original Batman doesn't seem to understand that Terry still needs to sleep, go to school, do homework, help his mother, and maintain his social life while fighting crime.
 * On Gargoyles, villain Demona is a gargoyle who magically turns into a human during the day, which means she loses the stone sleep that most gargoyles use to recharge. And rather than rest, she uses her human form to run a vast corporation. Word of God says that the magic spell compensates somewhat while she manages to get the odd couple of hours of rest in, and no, this isn't helping her general lack of mental stability.
 * Elisa comes pretty close to this at times. True, she works the night shift, but during the Avalon Voyage, she seems to be pulling day shifts as well as staying with the gargoyles at night. This is also true when Elisa is suddenly (though temporarily) shifted to the day shift.

Real Life

 * Polyphasic sleep cycles sleep for shorter periods more often, with the purpose of minimizing time asleep for sustained periods. Example schedules include a half-hour nap at 6-hour intervals, 20 minutes every 4 hours, or one 2 hour sleep with short naps during the day. Although popular in some athletic and professional circles, most users stop because of conflicts with other people's schedules. Can also manifest as a serious sleep disorder.
