As opposed to the malicious Cracker who uses his computer skills for profit and mayhem, the Playful Hacker normally wants nothing more than to explore new territory on the Net and learn new things. Sometimes, he plays harmless pranks which can cause clueless authority figures to confuse him with his dark counterpart. Even when his actions are not strictly legal, though, his intentions and presence are almost always benign—even heroic. This is what "hacker" used to mean, before mass media mutated it.
When a Playful Hacker and a Cracker collide on the Net, it's always the Playful Hacker whom authorities pursue first, a plot complication which puts additional pressure on the Playful Hacker to track down the Cracker, the true culprit. When the final face-off comes, though, it's going to be the Playful Hacker versus the The Cracker at high noon at the 0K Corral with virtual six-guns.
The Playful Hacker usually owns a Magical Computer, which allows him or her to do all manner of things impossible to normal computers and users, especially when engaging in Rapid-Fire Typing. (See Hollywood Hacking.)
He may or may not be a Mad Scientist depending on who you ask. Chances are a more-benign Playful Hacker might turn out to be a Reluctant Mad Scientist, or a Stupid Scientist. Modern iterations may also be Tech Bros.

- Matt Jeevas from Death Note is often depicted as this in the fandom due to his Chaotic Neutral hacking in the main series.
- Rebecca Hawkins from Yu-Gi-Oh!. Seto Kaiba is one as well but could fall more under The Cracker (he certainly never does this for fun), but, technically, the few times we see him hacking, he's helping out the good guys. His younger brother Mokuba is this as well.

He describes Estonia as his rival tweaker, and at one point, Estonia accuses Russia of hacking his blog and turning it into a fansite for himself. He didn't...and was quite upset at Estonia for thinking so.

In fact, she's introduced using her computer to spy on Minato when she takes an interest in him.
- Marvel UK introduced Adam Reynolds for one of their Transformers Generation 1 annuals.

Which is the equivalent of walking to the bank and ending up in the secret military lab in the middle of the ocean.
- An issue of Spider-Man Family had a couple of kids looking for the next big game stumble into one of Stark Industries' files.

- Attila in Dante 01, who repeatedly teases the head of the prison when he hacks into his computer.
- Aram Fingal (played by Raul Julia) in the Made-for-TV Movie Overdrawn at the Memory Bank, at least initially. He kicks off the film's plot by spending his work hours "scrolling up cinemas" at the office, but once his consciousness is placed in the HX368 supercomputer (long story) his shenanigans end up creating severe weather disasters all over the world, causing billions in property damage to the Evil Corporation that he works for.
- Stanley Jobson in Swordfish. Arguably Deconstructed—he's got the requisite mad skillz and moral compass, but this just means The Government is that much more smug when they catch up with him and punish him for his actions: destroying the FBI Carnivore program was actually praised by enough of the public to force them to parole him away from computers instead of giving him a prison sentence. But, when his alcoholic wife divorces him due to him losing his job (because they won't let him use computers), they have a judge award her with their daughter even after she marries the porn king she works for. The FBI even brags about how his daughter will end up "a fluffer in her new daddy's videos" as punishment for him screwing up their ability to read every American's email.
- Tony Stark, AKA Iron Man. The guy effortlessly hacks a live senate broadcast and several military satellites just to prove a point. He also has a tendency to hack other people's sound systems to play appropriate music for his dramatic entrances.

- Net in Feliks, Net & Nika is a genius hacker and amazing programmer.
- Replace 'hacker' with 'cracker' and you have the three guys who make up "The Smoking Gnu" in Going Postal. This being the Discworld, they hack the semaphore-driven "clacks" network, which is a telecommunications system, but without the electricity.
- As of The Science of Discworld II, Hex has also joined the Playful Hacker ranks, as it's hooked up to the semaphore network, has cracked their operations codes, and can slip messages onto the network for free, passing them off as internal signalling. So far as we know, it's only done this to save the UU faculty the expense of sending c-mail messages. Ridcully's reaction to learning this is to ask some serious questions, starting with "Could anyone find out we're doing this?"
- Catherine Jinks' Evil Genius Trilogy:
- Cadel Darkkon functions as this. Slightly subverted, as in the first book Cadel was closer to a cracker, given his initially amoral nature—until he met one of the victims of his destructive schemes.

- "Smokin'" Jay Gridley from Tom Clancy's Net Force.

- Wyatt Gillette from Jeffery Deaver's The Blue Nowhere.
- Ravirn. In a world where computer hacking skills and magic have combined, Ravirn definitely fits this trope.
- Snow Crash. Although his business card boasts of his badass swordsmanship and pizza-delivery skills, Hiro Protagonist's skills as a hacker actually serve him better in the story than his skills with a katana.
- Bob Salmon in the Doctor Who Past Doctor Adventures novel Blue Box by Kate Orman, who uses his skills to help the Sixth Doctor and Peri take down cracker Sarah Swan.
- Ender in Ender's Game, who cracks into the desk system in the Battle School and figures out how to send messages under other student's names while preventing other students from using his name. This is only used for pranks, of course, as Ender is only six years old at the time. And the computer system is deliberately set up to allow and encourage this sort of competition/play/hacking.
- In Vernor Vinge's cult-classic novella, "True Names", most of the members of The Cabal fall under both this and The Cracker. They're all out to have fun, and to gain bragging rights, but they're all also criminals. Of course, some of them are more criminal than others, so we do eventually get the classic Playful Hacker vs The Cracker showdown.
- Karma of The Girl from the Miracles District can break in anywhere thanks to her magical ability to manipulate numbers. She likes to have her fun, too - she once broke into secure bank accounts of a leader of an order of assassins, replaced all the values with 6,66 in whatever currency they were in, and then reset everything back to normal after a day just to show that she could.
- Fate/strange fake has Flat Escardos, an Idiot Savant who cheerfully goes about the Holy Grail War in hopes of making friends with every Servant. He's also an astonishingly talented magus who can rewrite meticulously laid defensive wards in four seconds simply by touching a building and flooding it with his magical energy.
- Directly inspired by WarGames, Richie Adler from the short-lived series Whiz Kids. Richie even acknowledges some similarities but says that he, as opposed to Lightman, is a genius. But then, his computer RALF is also a Magical Computer.
- Adam from Doctor Who was a Deconstruction of this character type. His playfulness and extreme intelligence made Rose find him charming and appealing, but as time went on it became apparent his lack of a distinction between a harmless prank and something dangerous and threatening; his worrying ambition; his cowardice; and his dangerous impulses all rather obscured his better traits. He ends up back home with a hole drilled into his forehead which opens whenever anyone snaps their fingers, denied the chance to explore the universe with the Doctor.
- Mac on Veronica Mars: a Playful Hacker with the tendency toward being a bit of a Cracker. She's helpful to Veronica in solving cases, but as Veronica herself operates outside the law for profit, Mac does the same.
- Penelope Garcia from Criminal Minds was this until her ex-boyfriend, a straight out Cracker, got her in trouble with the law. She hacked the government just to prove that it could be done, but he took files and leaked the data. She was given the choice to work for the FBI or get jail time.

- The Shaper faction in Android: Netrunner is comprised of these guys.
- Miniatures game Infinity features hacking as a core mechanic and has several characters that fit the trope: Valerya Gromoz and Isobel McGregor are both young women who became known for their hacking skills while Uhahu and Mary Problems are child-like expert hackers that put the former two too shame with both their skills and bratty attitudes.
- Metal Gear:
- B.B. from Metal Gear Ac!d 2. Instead of being childlike, though, he was—literally—a child (age negotiable, but still in Elementary School). He played comic relief throughout the game, culminating in him copying Psychic Powers from a boss and hypnotizing the President of the United States—totally ridiculous, but it worked because it was funny.
- One of Otacon's talents in Metal Gear Solid. He clearly takes great pleasure in hacking into his boss's files during the third act, and cheerfully remarks that the hacker label describes him "pretty well". In fact, that's why the FBI fired him.
- In Deus Ex, Silhouette's claim to fame is hacking a Superbowl broadcast and inserting anti-UN propaganda.

Just enter the password for a fabulous prize worth billions of credits.
Seriously, how many times can you walk past without investigating?
- Between the events of Mass Effect 2 and Mass Effect 3, Cerberus attempts to regain control of the Normandy after Shepard cuts off ties with them. Unshackled EDI's response? Spamming the Cerberus hackers with seven zettabytesnote of porn...from Joker's Porn Stash.
- The crew of the Normandy is joined in Mass Effect 3 by Samantha Traynor, who among other things enjoys strategy games and manages to impress EDI with her ability to sift through data to track a Cerberus shuttle.

- Shinji Naruse, a childish and Tsundere high school student in Lux-Pain is a gifted hacker who manages to break into the files of the main character's secret organization... because he can. He ends up facing the Cool and Unusual Punishment of having doctored (and dirty) photos of him posted on the internet by said organization.
- Yukabacera from Iji is apparently one, according to his hidden character pages on Daniel Remar's official site. He'll hack one of the station terminals in the room just to code a video game for other people's enjoyment. (This game can actually be played in Sector 6, the sector where Yukabacera is hiding) He apparently tries cracking his own logbook in his spare time, and is responsible for the Scrambler, which was your standard-issue Universal Translator before he got his hands on it.
- TRON 2.0: Jet Bradley is as bad as his Honorary Uncle (see the film section). His father is definitely not thrilled.
- You in Uplink, if you so choose. Hack someone's academic record and give him nonsense degrees! Change their status from "Single" to "Married" or even to "Deceased" for no particular reason. Hack into the bank and steal exactly one credit just because you can. As well as the player in the Spiritual Successor Hacknet.

- The Data Angels of Sid Meiers Alpha Centauri are an entire country of these, headed by Sinder Roze, a cybercriminal who got aboard the Unity by opting to work as the ship's network admin as part of her community service. The Data Angels are concerned greatly about the freedom of the individual and the freedom of information, which often puts them into conflict with the collectivist Human Hive and the fanatical Lord's Believers. The Data Angels have access to Probes which are not only more effective than those of other factions, but much cheaper as well, and they gain any technology for free when it is discovered by three other factions. Unfortunately, they can't use the Power value in social engineering, giving them fewer options for building a strong military, and they have a much harder time keeping order in their cities and generally working as a group - in a nation of individualistic hackers, everyone wants to have a voice, and nobody wants to be just another soldier in someone else's army.
- Sombra from Overwatch blurs the line quite a bit in deciding whether or not she's a Playful Hacker or a Cracker. On one hand, her motives seem just, which is to know who really runs the world, and she has an extremely prevalent mischievous streak, but she works with the terrorist organization Talon to find this info, and is also quite keen on "making friends" to obtain more.
Moira: Started any wars lately?
Sombra: (cheerily) I'll have to check my schedule.

- TOME: The White-Hat Hacker.
- Halo: Many Smart AI are capable of doing this when plugged into a network. Cortana in particular was designed with the intent of infiltrating any system, even Covenant-designed and controlled ones, and taking them over. She's even subverted control from Forerunner systems. The novels describe her as having every single hacking protocol that ONI could fit inside of her at the time of her creation, plus quite a few she made herself (and would often amuse herself by testing said security systems to see how fast she could break through).
- Neptunia: Nepgear moonlights as one when she wants to with her trusty N-Gear, with it being casually mentioned she's used it to hack into government databases or other servers. Luckily, she's only ever really used it in order to find info the bad guys want to keep hidden.

- Sollux Captor and Alpha Roxy Lalonde from Homestuck. Sollux is probably a better example of the trope—he once managed to initiate contact from Terezi to Doc Scratch. Who doesn't have an account on the chat client. And uses a TYPEWRITER. AND LIVES ON A MOON.
- The aptly named Hacky from Sidekicks has a superpower that allows him to do so. Although he denies it.
- Hachuling from Tower of God, a cheerful fellow who can take over your Lighthouse like it's nothing.
- In Carmen Sandiego, Player is this type of hacker. He specifically calls himself a white-hat hacker when he first talks to Carmen, back when she was Black Sheep.
- Occasionally in Code Lyoko, when Jérémie is testing a new program. However, he normally uses the Supercomputer to escape from sticky situations. For example, when the school staff tries to find out about William's disappearance and Jérémie uses his voice synthesizer.
- Mouse from ReBoot. Even weirder when you consider she actually lives inside a computer. One could guess she's some sort of hacking software (just like how Bob is essentially a computer security suite).
- Odie in Class of the Titans, is this at times. Especially in "Trojan Horse" where he hacks the city's main frame for his own amusement, causing the traffic lights to flash like a disco and Video Game/Pac-Man to appear on a ATM.
- Once in Robot Chicken, the nerd accidentally nuked Canada while looking for cheat codes. He was sent to Guantanamo Bay and waterboarded until he told them where Mordor was.
- Adventures of the Galaxy Rangers: While he's more of a Technopath, Doc Hartford never lacks for a sense of humor, and is more likely to try to sweet-talk or trick an AI than overpower it.

- Robin in Young Justice.
"I hacked the motion sensors."
- Blkmrkt, the Asian and Nerdy 11-year-old from Major Lazer.

- A hacker called NeoN exposed a Russian company's propagation of the fake antivirus program MS Antivirus and posted their earnings from the fraudulent program. The company's name? Bakasoftware.
- Lulz Security/Antisec members consider themselves to be these, as evidenced by their snarky, meme-laden press releases.
- The NSA has their own department of white hat hackers (better known as "penetration testers", since certain less technically-literate management types tend to panic at the word "hacker") that constantly test their own systems. And do some other stuff.
- In fact, many tech-based industries (which is most industries nowadays) employ penetration testers, also called "ethical hackers", and often independent hackers can tip companies off about security vulnerabilities as well.
- M.I.T. has a long tradition of "hacks" dating back long before computers were available, with their own website dedicated to tracking them, as well as at least five books—one of which is published by the university's museum press.
- During the PewDiePie vs. T-Series competition, two hackers under the aliases of HackerGiraffe and j3ws3r managed to hack ten thousands of printers and print out messages encouraging people to subscribe to PewDiePie and upgrade their printer security (highlighting how serious printer hacking can be). They also hacked many smart TVs running Chromecast with similar messages. Nest cameras and the Wall Street Journal were hacked also to promote the subscribing to PewDiePie.
