She's disorganized and a jokester, but hey, she's really fun! The resident class clown, Harley, lives for the LOL's and loves playing over-the-top pranks. Keep an eye out for her, she's a sneaky one. The class clown's top three traits are being quick-witted, fun, and unpredictable. One for her, PUN for you! This fun-loving girl LOVES a good pun, but who doesn't? Probably people who aren't very punny. Harley knows there's a clown inside everyone just waiting for the opportunity to put on a big red nose, floppy shoes and burst out. She feels like it's her job to make that happen whether her friends want it to or not. Good thing Harley's an agile acrobat, because that's the only way she's been able to twist and turn out of some pretty tight situations.

Harley Quinn grew up in Gotham City with a strong love for dinosaurs and became a know-it-all on the topic. On fateful day, she saw a hero on TV and decided she would become one, too. In her teens, Harley Quinn was dedicated to building the biggest video empire in the world. The Harley's Quintessentials, HQTV, self-produced video channel was born. She is a member of the Vehicles Club and gives sanity checks on the School Internet Radio Station. Harley Quinn learned her new roommate was Wonder Woman. She used a joy buzzer on Wonder Woman as they shook hands. The next morning, Harley made a racket and congratulated Wonder Woman for their first morning. As she rustled through Wonder Woman's closet, Harley got tangled in the Lasso of Truth. She was compelled to tell the truth and admitted to clogging the toilet last week. She then tried to help Wonder Woman decorate with a glitter bomb. Wonder Woman took the blast instead of her wall and frames. While Wonder Woman tried to study math, Harley took it away and complained it was boring due to a lack of romance and explosions. Wonder Woman indirectly asked to be left alone. Harley got the message and read quietly and sullenly on her bed. Wonder Woman felt bad and asked to hang out. Harley was overjoyed and hugged Wonder Woman.

When Wonder Woman struggled with the requirement to make a super suit, Harley came to her aid and recruited Bumblebee and Katana to help. During finals, Harley saved Lucius Fox's life but throwing out her oversized whoopee cushion for him to land on after he dropped from the Amethyst atop the school. Harley attended the party celebrating Wonder Woman's first supervillain defeat. She informed Wonder Woman her battle with Giganta made the front page of the news and showed it on her phone. On the day Supergirl was set to arrive, a group of supers took on Killer Croc in the city. Harley dodged his tail and kicked him in the snout then tossed a pie in his face. While he went after Cheetah, Harley swung a wrecking ball into him. She admired Supergirl for starting off on a "real bang" and crashing into the cafeteria. She showed Supergirl to the dorms and talked to her for six hours straight. Once Supergirl revealed she was having trouble with setting up her Internet connection, Harley yelled at the top of her lungs for Barbara Gordon.

The next day, Harley quizzed Supergirl on the Three Pows but they bumped into Vice Principal Grodd. Harley shared the rumor Grodd was a supervillain that Waller got out of prison through work release. Harley later took part in another Save the Day involving Giganta. She used her giant mallet to squash Giganta's left foot. She was proud her giant novelty handcuffs finally came in handy. She briefly fought Speed Queen in the siege of Super Hero High. After much effort to get to the cafeteria first and snag the last piece of superfood cake, Batgirl and Supergirl fell short. Harley snatched the piece at the last second for herself. Her new video blog series "Harley's Quinntessentials with Harley Quinn" was a hit and she became Metropolis' hot new trend. Capes & Cowls Cafe offered a Smoothie Quinn that safely exploded in your face. The newfound fame went to her head. However, Harley fever continued to increase and soon there was a Harley Con, where anyone could be Harley Quinn.

Naturally, Harley was offended and set out to remind the city there was only one authentic Harley Quinn. She planned to pull off a prank and use a park fountain to create a flood of bubble bath. However, two cosplayers hampered it. She streamed another blog and declared Harley-fying was over. She stated she'd only blog about boring old sugar free cupcakes. The trend broke and Metropolis mostly returned to normal. Harley Quinn was soon awarded Hero of the Month. For Advanced Stakeouts, Principal Waller assigned Harley Quinn and Lady Shiva group project partners. That night, they waited atop a roof in the city and searched for the deadly assassin Cheshire. Shiva was too serious for Harley's tastes and she began to entertain herself, giving away their position. Cheshire found them and rushed them. They dropped down but Harley broke her fall with an awning and crate of oranges. They quickly scaled the side of the building back to the roof but Cheshire was gone.

Harley egged Shiva to tell her a joke, unaware Cheshire was behind her. Shiva told a knock knock joke and forced Harley to duck as she punched Cheshire out. Harley came to appreciate her impeccable timing and great punchline. Shiva asked Harley not to tell anyone. On the day before semester finals, Harley retired to her dorm room to relax and listen to dubstep instead of study more. After Batgirl complained to Harley about the noise, Harley decided to throw a party in her room after school. She was annoyed to see Wonder Woman, Batgirl, Supergirl, Poison Ivy, Katana, and Bumblebee didn't come. She checked Batgirl's dorm room, then found Bumblebee's honey smoothie spilled in an alley and walked through downtown. She happened to encounter Solomon Grundy robbing a Metropolis Bank branch. She nailed him with a glitter bomb and demanded to know where her friends were. He exclaimed he didn't know anything and just wanted to rob the bank. She noticed vines on the bank's exterior and realized she was on Ivy's trail.

She followed the trail of plants to the Lexcorp Garden Supply and was surprised Ivy fell for such an obvious trap. She pounded and kicked on the door demanding her friends. Luthor eventually realized she was Harley Quinn and admitted to underestimating her. He activated a trap door and added her to his Kryptonite-powered prison. The next morning, the girls escaped, defeated Luthor together, and convinced Waller to pass them on the finals. On the Wednesday night before the Hero of the Year ceremony, Batgirl alerted Wonder Woman, Supergirl, Bumblebee, and Harley of an an intruder. Everyone except Harley helped search the school. She threw her comm bracelet off and went back to sleep. The next day, Harley volunteered to help guard the Amethyst but took Big Barda under her wing and gave a tour of the school. The next day, Harley took her to Capes & Cowls Cafe but was revolted by Supergirl's smoothie order: a large double spinach, sardine, and pickleberry.

The next day, Saturday, Harley helped guard the campus due to heightened security concerns. She and Ivy heard Big Barda in the forest and found her and Supergirl in a battle against Dark Opal. Harley made use of the trick boxing glove in her backpack. Katana accidentally discovered Opal's Shadow Demons were vulnerable to light and the girls forced them to retreat. Harley continued to interrupt Lois Lane's interviews and hog the lime light. She was less than thrilled with the return of the shadows but loved using her mallet on them. After awhile, they started running away from her. The following semester, Harley took part in Wonder Woman and Supergirl's street race in her jeep. She won the race easily when the other girls stopped to capture Double Dare. She enjoyed a slice of superfood sugar free cake on the hood. during Intro to Epics, Harley asked Professor Etrigan about Odysseus. He went into detail about the hero's arduous journey. Harley was eager to go to Wonder Woman's slumber party.

At Wonder Woman's request, Harley "informed" anyone going should meet at the Batjet in one hour. However, it went missing. Harley tagged along with Wonder Woman but could hardly keep up pace with the stressed out princess. Harley reassured her they would find the Batjet and get to Themyscira in no time. They questioned Cheetah with the Lasso of Truth but she didn't know anything about the theft. Harley mused someone would need some major magical maneuvering to get the Batjet. Wonder Woman got another idea. They went to talk to June Moone, professor of art and an enchantress. Moone talked about her potions and Harley was on the receiving end of her Bag of Wind and gem that scrubs dishes. Harley demanded to know who had her last Ultimate Unlocker. Moone talked about Etrigan and his surprise birthday party. Wonder Woman and Harley responded, with Katana, to a disturbance at the greenhouse. They forced Chompy to spit out Lobo. Ivy was irate and told them Lobo was trying to break into the greenhouse.

Harley tagged him with her mallet and Ivy bound him with vines. He confessed he was pretending to be interested in transferring to Super Hero High in order to track down Etrigan and collect on a bounty. Harley was smitten with Lobo and asked what kind of make up he used. Ivy, Batgirl, Harley, Wonder Woman, Katana, Hawkgirl, Flash, and Bumblebee came to the aid of Supergirl's team at the Portal Coffee Shop. Harley stayed on Wonder Woman's team and ventured to the Underworld. Harley was the first to step on a red stone and set off a trigger mechanism that created a geyser of flame. They found Etrigan but were captured by Trigon, lord of the Underworld. Harley puffed herself up but Trigon stated she had an eternity to reconsider her insults. Miss Martian reappeared and freed everyone. They made it back to the Portal Coffee Shop just as the portal closed off. Wonder Woman's team headed to Smallville to join Batgirl's team in the pursuit of the stolen Batjet.

Harley and Katana took the Invisible Jet on account of them not being able to fly on their own. Harley caught Black Condor off guard with a party favor then Ivy tied him up with corn stalks. Once Black Canary, Condor, and Magpie were taken away by the Smallville Special Crimes Unit, the girls continued onto Themyscira. Harley couldn't wait to commence the all-night games, movies, and hair braiding marathon. She brought out "The Little Mera-Maid," "Mister Twister," and "Lasso of Truth or Dare" board games but everyone else was fast asleep already. Harley tried to entertain herself and read "The Odyssey" again but it reminded her too much of the day's festivities. She joined they others and got some shut eye. Harley barely got to the school's time machine bus in time for the Intro to Prehistory field trip to the Jurassic Era. She bumped into Liberty Belle, the course teacher, and helped gather back up the permission slips. She quickly got into a little rivarly with Batgirl about who knew the most about dinosaurs.

An accidental encounter with dinosaurs led to the bus getting split into two and launched elsewhere. Harley became disheartened when Batgirl took charge of repairing the bus on her own, spotted Liberty's red glove first, and fired a grapnel line up a tree before she could footholds into the bark. After Batgirl and Liberty Belle descended the tree, Harley decided to take a Pterodactyl egg and keep it as a pet to top Batgirl. The class returned to an alternate 2016 where Super Hero High was now Savage High and the principal was Vandal Savage. While Batgirl repaired the Time Machine, Harley was supposed to look out for Doc Magnus. Before Batgirl could stop her, Harley activated the bus and they ended up 134 years into the future, 2150. Batgirl and Harley were captured by the Atomic Knights and accused of being spies for Savage. Harley exonerated them by playing with the knights' Giant Dalmatians. She was surprised taking one dinosaur egg would change the future. Batgirl was irate and blamed her for everything.

To make matters worse, the egg was back at Savage High. However, the bus' self-driving mode was broken and they jumped to random points in time. They met Amelia Earhart in 1914, Emily Dickinson in 1847, Native American women who recorded in a myth called "The Two," witch fearing Puritans, and a young Amanda Waller in the late 1980s on June 15. They returned to Savage High in 2017 but Savage was waiting with his faculty. He revealed he had been hunting them for centuries and long vowed to destroy them. Harley was hit by Quilt's Goo Grenade but broke off to search for her backpack but when she found it, the dinosaur egg was gone. She searched the campus to no avail then heard a screech from the cafeteria while she tried to concentrate. Harley entered the cafeteria and found the pterodactyl hatchling. The two hit it off very quickly. Harley fed him some Sloppy Joe and named him Bitey McPuddin' Face. She knew Bitey belonged in the past and vowed to make sure he would get there. They charged Principal Savage in a tandem.

Bitey attacked him while Harley rescued Batgirl with her telescoping mallet handle. They returned to the bus with the others and made the jump back to the Jurassic Era. Harley decided to stay in the past with the dinosaurs where she couldn't ruin anything. Batgirl apologized and admitted she would go back in time and take back what she said if she could but was terrible at time travel. Harley perked up. Batgirl reminded her she was good at acrobatics, making people laugh, stealing dinosaur eggs, and better than her at dinosaurs. They made sure Bitey and its mother were reunited then returned to the bus. The present was mostly restored except the principal was Luicius Fox. Batgirl deduced the problem and asked Harley to come with her on the bus because only she could help. They checked in on Amelia Earhart and Emily Dickinson but those parts of history were intact. They went back to June 15 in the 1980s to save a young Amanda Waller from Solomon Grundy. They were knocked into trash cans.

Batgirl stopped Harley and removed a banana peel from her head. Waller joined them and together, they defeated Grundy. Waller thanked them and told them to call her Amanda. The girls were smitten. Before they teleported to the present, Batgirl advised Waller to remember three words, "Super Hero High." The present was restored to the way it was before. Harley and Batgirl found Waller. Harley couldn't help herself and hugged Waller then called her Amanda. Waller knew they came back from the 1980s and admitted she should be thanking them. She finished by warning them never to call her by her first name or they would get detention. Harley had a hard time executing her comics project and looked for the right supplies in June Moone's closet. She found a tube of magic paint. Harley's comic came to life and the anti-hero version she drew of herself went bad and animated the other projects in the room. They went on a rampage in the school then Metropolis. Harley opted to hide down a manhole on 47th. She overheard Batgirl looking for her and appeared.

Batgirl stated she was the only one who could stop the other since it came from her super ego. Harley warmed up to the idea of helping. Supergirl arrived and asked Batgirl if she told her they needed her creativity. Harley agreed to help. They returned to Super Hero High and asked Harley to write and draw a new comic to fight the bad art. She had a difficult time settling on an idea then Enchantress burst into the room. Unaware June Moone was not in control anymore, Harley tried talking to her and was tossed onto a painting. Harley was bound and couldn't warn Supergirl, Batgirl, Frost, and Ivy in time. They entered and Enchantress stole the Magic Paint they just made. She then sealed the supers in the art closet and cast a locking spell. Since only the door was enchanted, Supergirl flew through the ceiling. The girls reunited with Wonder Woman's team, allied with the animated art, and took on Enchantress' army of animated monsters but were defeated. As the animated Doomsday carried Ivy away, Harley vowed that was the last straw and she had to save her friends.

She returned inside and finally got inspired. She recalled how her papers were always returned marked by her teachers' red pens. She squeezed out some Magic Paint then raced outside. A red pen she named Li'l Red was animated. It erased Doomsday to save Ivy then wiped out the rest of Enchantress' army. Harley's drawing of herself admitted she was impressed but Harley wasn't done yet. She ordered Li'l Red to take care of the remaining artwork. The Harley tried to plead with her and tempted with a team-up. Harley erased her citing it was a lot more fun to be good and she wasn't risking having the spotlight taken from her. She raised Red up the air and declared the pen was mightier than the sword. Supergirl flew around Enchantress and generated a vortex to neutralize her and her attack. The girls weren't sure about calling the Special Crimes Unit on her. Harley believed Moone was still in there. Batgirl brought up Moone's comic and how she knew Enchantress would take over, but Harley countered it was just a self-fulfilling prophecy.

She recalled one of Dr. Arkham's posters and cited the stories people told themselves about themselves shape how they saw themselves, and to change the story would change themselves. Harley was surprised to learn Wonder Woman and Supergirl saw a therapist like her then admitted she was thinking about going into the psychology field when she got older. She addressed Moone but Enchantress stated she consumed her. Harley countered that's what she'd say if she was scared her maneuvers might work. Enchantress vowed to destroy her but Harley had Wonder Woman lasso her in place. Harley continued with the heart-to-heart and told Moone the Moone in the comic was nothing like the one she knew. Wonder Woman stated the real Moone was strong, Supergirl added talented, and Katana didn't think she wouldn't let a rage monster take over her life. Harley stated she kept telling herself she wasn't strong enough to fight Enchantress. Moone started to break through and asked if that meant she could beat her.

Supergirl implored her to believe in her super self. Moone regained control and returned to normal. Waller reinstated Moone on the condition she went to see Dr. Arkham, the school counselor, every week to learn how to deal with her emotions correctly. Later on, Harley went to see Arkham for another session and it ran long. Harley told him about this green haired boy who always pulled on her pigtails and teasing her. Arkham stopped her to clarify this event took place before kindergarten. Harley confirmed it, told him she was precocious, and continued on. Harley Quinn was voted "Most Dynamic Duo" with Wonder Woman in the Super Hero High School Yearbook. Harley was also voted "Class Clown" and "Messiest Room." For summer, Harley enrolled at Metropolis Theater Camp. During a break, Harley checked everyone's social media accounts and saw all the fun they were having. Harley missed everyone and couldn't wait for summer to be over.

Halfway through summer, Harley practiced a monologue but was blasted with a wind gust by Siracca, demigod of wind and Wonder Woman's half-sister, amid an invasion by Ares and Strife. Harley found Ivy wrapped up in vines and freed her. They in turn captured Demeter, goddess of agriculture and half-sister of Wonder Woman, in a tree. Harley advised her to stay still or she'd know how a pinata felt like. She joined the battle against Ares and tried smashing a foot but fell under Strife's spell. She was angry Ivy never called, but Ivy retorted she was waiting for Harley to call her. Strife's hold was broken when Wonder Woman professed her sisterhood with everyone and called Harley the best roomie a girl could have. Harley was one of Wonder Woman's guests to Themyscira, after she invited herself, to celebrate the Party of Plenty but ended up fighting Ares, who was mad Zeus didn't come to his feast. Ares burned her mallet to a crisp but Wonder Woman had her get the Amulet of Harmonia from the Hall of Honors to defeat Ares with.

Catwoman tricked Harley into thinking there was an open casting call for a play in the auditorium and told her she was perfect for the role of damsel in distress #1. Harley practiced her pleas of help. As Catwoman hoped, Harley's lines were heard by Supergirl at Capes & Cowls. Supergirl, Wonder Woman, and Batgirl returned to school thinking Harley was in trouble. Catwoman proceeded to steal the Amulet of Harmonia off Ares. The girls found Harley on the back stage and asked if they came for the audition, too. Irritated with Catwoman's lie, Harley had little time to vent and helped deal with Ares. From Batgirl's Mobile HQ, Harley emerged from the rear with a large grapnel cannon and fired. She wrapped one of Ares' legs and Batgirl hit the gas while Wonder Woman pulled on the other leg. With Beast Boy, Hawkgirl, and Miss Maritan, they forced him to the pavement. By time of Grodd's near kidnapping by his former subjects, Harley was sent to detention by him 212 times. 213 after everything was cleared up.

Harley worked with Mera, Katana, and Batgirl in going after Mrs. Clayface after she stole three purses one evening. They surrounded her at a fountain in Centennial Park but Mrs. Clayface shoved her and Batgirl to the ground. Mera tried to help but only made Mrs. Clayface bigger with water. She knocked Katana into the bushes then escaped into the sewers. Harley later got a pet monkey named Calliope after Waller changed the school's "No Pets" policy. Harley and Calliope enrolled in Grodd's Super Pets class. She congratulated Calliope as they hung from some ropes. That night responded to the Save the Day alarm at the Centennial Park Zoo. Harley and Katana arrived on the former's quad. Harley took on Croc but he took her mallet away. Croc chided her for calling him an alligator but Supergirl picked him up, spun him around, then threw him across the zoo. The supers chased Killer Moth's red herring robot into a cage and were trapped. The Super Pets came to their rescue.

Harley worked on applying stink bomb technology to her quad in the shop. Because she wore a face mask, Harley was the only other person besides Ivy who didn't fall asleep from her Sleeping Poppies experiment. Ivy tackled her before she could remove the mask. Ivy explained what happened and Harley knew she was in a lot of trouble. Ivy had an idea and had Harley drive them to a swamp in search of the rare Rise and Shine Orchid. They were targeted by Solomon Grundy for a meal. Harley was upset when Grundy jumped on the quad and warned him not to ruin her new paint job. She pushed a button and a spring loaded boxing glove punched Grundy off into a pond. Ivy saw the orchid but Grundy was angry. Harley wondered out loud if there was anywhere else they could look. Ivy summoned several vines to immobilize him. Ivy was still unsure how to distribute the pollen. Harley suggested using her quad's stink bomb technology. It was a total success.

As Wildcat drove a class on a field trip, Harley tried to hype it up until Wildcat revealed they were going to the Gotham Dentistry Museum. Harley stopped and concluded they couldn't all be winners. Once Giganta found them and demanded her stolen earrings, Harley took matters into her own hands. She opened the door and punted Wildcat into a dumpster then took the wheel. Giganta leaped out in front of them but Harley pushed a button on the dash. The front cab split off into its own vehicle and Harley took Supergirl with her, leaving Katana to drive the bus and told her to go right. They evaded Giganta but she started to throw cars at them. Eventually, they learned Cheetah was the culprit. The field trip continued. Harley admitted to a newfound respect for her teeth. Harley fired her squirt gun into Trigon's face but had to take evasive action when he fired at her. Harley used her quadcycle for a vehicle assignment and was passed by Doc Magnus. She tried teaching Barda how to drive but Barda hit the brake hard.

Harley went flying. Then Barda started drifting backwards on the quad. Harley reminded her to always set to park and ran after Barda. Harley and Wonder Woman were co-editor's for the yearbook. Harley preferred to take photos of supers having fun so that years from now, they wouldn't forget. She got a shot of Catwoman squirting milk after Frost told a joke in the Capes & Cowls Cafe and one of Batgirl and Supergirl making funny faces. On the day layouts were due at the printer, she learned that Wonder Woman also had her own version of the yearbook but didn't want all the photos to be of supers being heroic. She rushed off on her quad to get to the printer first but ditched her quad to take a shortcut through a construction area. Wonder Woman tackled her out of the way of a wrecking ball then laughed at a group photo she almost forgot about. Before they left for the printer, Harley took a pic with her. Harley was hit by the compassion of indigo light after Star Sapphire's ring was cracked. Sapphire tricked Batgirl, hit by greed of orange light, into snatching her pie. They were restored to normal. Harley threw the pie in Batgirl's face and laughed.

Harley was cast as Oberon and Puck in A Midsummer Night's Dream. Harley learned Batgirl invented an app to avoid Hawkgirl when she was on hall monitor duty. To get it better exposure, she renamed it the Anti-Hall Monitor and soon every student except Hawkgirl had it on their phone despite Harley promising to keep it a secret. Harley declared to Batgirl she was a hero to the school and treated her to smoothies at Capes & Cowls. Upon returning to campus, Batgirl and Harley were blasted by the Anti-Hall Monitor and ended up in a prison with the other supers. She tried to pin the blame on Batgirl. Harley cracked after 53 seconds. Harley forgot about an Algebra quiz but Calliope tried to pull the Save the Day alarm. Grodd caught Calliope and didn't believe Harley's alibi. They were both put in detention. Bumblebee was stuck in her miniature form from stepping on one of Harley's buzzers. She tried to reach out to Harley in detention but she thought it was a ghost. Harley freaked out and promised Grodd she was going straight. She soon stole Poison Ivy's sage and burned it in the detention hall to get rid of the ghost. Grodd just shook his head.

For the annual gift exchange, Harley stole a wrist watch from Batgirl's dorm room and wrapped it. As a prank, Harley delighted in everyone being too afraid to take her present. In the end, Harley's present ended up with Batgirl and she recognized it. Harley played a prank on Mera by filling her pool with something and couldn't wait to tell someone about it. Despite not liking math, Harley decided to compete in the Tri-Matholon for the Math Club after Bumblebee and Supergirl told her about the winner getting the Pi Trophy. They did a mock multiple choice exam to practice for the first leg of the competition. Everyone except Harley fell into an odd trance and focused on completing the exam. She didn't get why there were letters and weird symbols so she decided to doodle a clown head on her exam. Seid called time and looked through the papers. He realized Harley solved the Anti-Life Equation with the highest test score. All he had to do was carry the one. He revealed his true form and the supers snapped out of the trance.

Darkseid declared Earth was his. Harley wanted to opt out of the rest of the Matholon. He introduced himself and his plans but Harley kept interrupting him, finally getting the fake name then asking what his degree was in. Darkseid flew to the roof and used the Amethyst to transmit the Equation and turned Earth into a world filled with Darkseids. As everyone was transformed into Darkseid, Batgirl told Harley, Raven, and Bumblebee to re-activate their Anti-Hall Monitoring app. They were teleported to the Anti-Hall Monitor's pocket universe and were spared from the Equation's power. Harley became hysterical and asked Batgirl what the solution was. Keying on Harley's words, Batgirl realized they could change the solution to the Equation by adding new variables, namely making the other supers remember who they were. After Wonder Woman, Supergirl, and Katana were changed back, the Amethyst reverted to normal and changed everyone back. Darkseid was shocked and thought it was impossible. The supers attacked him until he retreated.

(Novels only) Harley's HQTV got so many hits she was at the point where she could get a sponsor but she held off so that she could stay independent. She heard Star Sapphire's parents might be interested in buying part of HQTV. For the 100th Annual Super Triathlon, Harley was the team videographer. As the festivities started, Harley managed to get a brief interview with both Superman and Hippolyta. In several months, HQTV became the to go to video channel for everything super hero. After Katana defeated the Dragon King and was made Hero of the Month, Harley played a prank on the school. She hid atop the Amethyst tower while pretending to be in trouble. She was given two weeks of detention and forbidden from posting any videos on HQTV. Harley got an idea to expand her channel beyond Super Hero High with reality television. Her first idea was the Dance-O-Rama competition. She called a 12-way tie but reactions were polarized. She came up with a Battle of the Bands for the next feature but called it off to help stop Lion-Mane from stealing a priceless jeweled lion statue. She smashed his foot with her mallet after mistaking him for Beast Boy.

Harley went to see Dr. Arkham and told him how she couldn't sleep from being so busy and couldn't hang out with her friends because of work on her web channel Harley's Quinntessentials. At some point he fell asleep then blinked and told Harley she understood laughter made people happy. Harley cut the session short and was about to leave. Arkham asked her why he was holding his magnifying glass. A fan of Harley's Quintessentials, Jervis Tetch, the Mad Hatter, wanted her audience of followers to get him started on a road to fame and fortune. He would mind control the masses as they tuned in. He devised a plan to use the Krazy Karnival to capture Harley and the other supers. Harley got a mysterious hand mirror in her fan mail. It was carved from teak and had inlaid pearls. Under Mad Hatter's orders, Mirror Master used the hand mirror to image map Harley's movements, quirks, and anything else to use for a Harley mirror hologram's speech bank.

Harley got an idea to hold the Battle of the Bands rematch at the upcoming Krazy Karnival without asking the owner, Jervis Tetch, first. Harley discovered Lois Lane found the elusive Tetch first but they interviewed him together. The High-Tech Bubble Machine broke the world record for the biggest balloon but it was a ruse to encase the entire carnival in an impenetrable barrier. Tetch proceeded and had the mind-controlled Green Team pillage Metropolis with clones created by Mirror Master's technology and sent out fake Harley's Quintessentials that claimed the supers didn't care about saving Metropolis. Batgirl and Flash subdued Mirror Master while Harley went into the Amazing Maze alone. Tetch sat on a red velvet throne, drinking tea, in the middle of the Amazing Maze. He revealed the carnival was all to get close to Harley to talk. Harley secretly broadcasted Mad Hatter's speech to the world through her QuinnCam then destroyed it to prevent him from using it.

Harley pursued Hatter through the carnival grounds to the Ferris Wheel. As Hatter clung to a cart, he begged for mercy. Harley demanded to know how to break the bubble barrier. Hatter stated she just had to get obstreperous to break it. Harley pulled him up but he pushed her off the cart. Harley's gymnast skills saved her. He ran to Lost and Found to free his workers. Harley threw her body into the maddest tumble and landed on his shoulders. Hatter's hi-tech hat went flying. She smashed it with her mallet and all the rides went dark. The Battle of Bands rematch began. Harley told everyone to be as loud as they could. The noise from the music started vibrating the barrier. Harley remembered she had the strength tester bell and hit it the hardest she could with her mallet. The barrier shattered. To her surprise, Harley made Hero of the Month. She planned to cover the Green Team's takeover of the Krazy Karnival and start a new segment called "Good Deed of the Day" featuring supers and citizens helping others.
