The Justice Brigade was at home when a circus pulled into town. When they were all set up, the city started to buy tickets and go into the big top. While purchasing their tickets, Jake snuck behind the big top, tripped, and fell near a tent. Then he overheard somebody talking inside the tent, so he opened it somewhat and spied on whoever was inside it. The girl said, "Can't wait for tonight's show. The audience will never know what hit them." Jake whispered, "I don't like the sound of that." The Justice Brigade all entered the big top and took their seats. Iceboy kept his eye out for anyone who looked suspicious. When the show started, a stage rose out of the ground. The clown on the platform said, "Hello, Las Angeles; I am Clownpira! Are you ready to laugh?" Clownpira sprayed one of the other clowns with a water gun, and the audience laughed.
While the show was happening, Hannah heard a crash from outside, so she snuck outside and investigated. After leaving, Jake wondered where she had gone and returned to watching the show. Then, Clownpira used her powers to bring the clown car to life and turn it evil. The audience laughed when they saw that, but Jake didn't think it was good. Jake looked to his left, then right, and figured it was safe. Then he ran up the bleachers, jumped over the top, and flew so he wouldn't hit bottom. While in the air, he changed into his superhero uniform and flew up to Clownpira.
Clownpira was enjoying the audience's laughter when Iceboy launched his ice at her car and froze it. Clownpira looked in front of her and saw Iceboy. Iceboy said, "Hey, is there a clown in the house? Because the only clown here is you." Clownpira said, "Oh yeah. We'll see about that." Clownpira tried to blast Iceboy with her powers, but Iceboy shielded himself with his Ice Shield. Then Clownpira pulled down her hat and vanished while she laughed evilly. Iceboy flew up to the trapeze and saw Clownpira on the other side. Clownpira and Iceboy ran up to each other on the trapeze wire and smacked hands to see who was mightier. Iceboy said, "Who writes your jokes, the same idiots who tell you your performances?" While Clownpira was fighting Iceboy, the crowd kept laughing at what they saw. Then Clownpira smiled at Iceboy and started to push him down, and Iceboy started to sweat. Iceboy said, "The laughing makes her stronger." Clownpira said, "Got that right, Pudding. And the more kids laughing, the stronger I get." Clownpira threw Iceboy away, and he fell to the ground. Clownpira flew down to Iceboy and looked down at him while she smiled. Clownpira said, "You think I'm strong now? Wait until my final performance AND THE WHOLE WORLD IS LAUGHING AT ME! THEN YOU'LL ALL BE MY SLAVES!" Clownpira kicked Iceboy up and then away.
While Iceboy was handling Clownpira, Hannah investigated what she heard while Daisy and Frank kept laughing. When Hannah got outside, she saw four circus performers robbing the bank, jewelry store, electronics store, and City Hall. She ran behind the circus tent and changed into her superhero uniform when she saw them. Heatgirl said, "Hey freaks, don't you know you're missing your show?" The circus freaks looked behind them and saw Heatgirl standing by someone's car. Lina said, "Of course, we know. Now get lost before we destroy you." Heatgirl said, "I think you'll find I will destroy you." Sam said, "Really?" Sam lifted a giant truck and threw it at Heatgirl, but Heatgirl jumped out of the way and kicked Sam down when she landed. Roger then threw his whip at Heatgirl, and it tied around her. Roger said, "You're no lion, but I guess I tamed you." Heatgirl used her Heat Vision to break the whip. Heatgirl said, "Now it's my turn." Heatgirl turned her hand red, and it turned a lamppost red. Then, the lamppost tied around Roger, and he fell to the ground. Lina jumped up and stood on the powerlines with one foot. Lina said, "Catch me if you can." Lina ran across the powerlines since she was a tightrope walker. Heatgirl tried flying after Lina, but Danny blew a silent whistle and called many dogs. Danny said, "Get her." Danny snapped his fingers and pointed at Heatgirl. Once Heatgirl caught up with Lina, she stood ahead of her and wiggled the power line to make Lina lose her balance, but Lina stood on one foot and kept her balance. Since Lina had to maintain her balance, Heatgirl flew up to Lina and punched her off the powerline. Heatgirl said, "Three down, one to go." Then, a bunch of dogs ambushed her, but she made a firewall to separate them from her. Heatgirl then shot her powers at Danny and knocked his silent whistle out of his hand. Once he dropped his whistle, it fell into the sewer, and Heatgirl stood ahead of Danny. When the dogs came after her, Heatgirl flew up, and the dogs ran over Danny instead. The circus freaks ran for it, but Heatgirl flew after them, hoping to catch them. After Heatgirl lost the circus freaks, she saw Iceboy on the ground and woke him up. Heatgirl said, "Iceboy, Iceboy, are you there? Iceboy?"
Iceboy woke up and saw Heatgirl in her superhero uniform. Heatgirl said, "Iceboy, what happened?" Iceboy said, "All I remember is fighting Clownpira in the tent, and the crowd laughed. Then she kicked me away. I must have gotten knocked out. Where'd you go?" Heatgirl said, "I was fighting four circus freaks who tried robbing everyone blind, but they disappeared." Iceboy said, "People don't just vanish. There must be an explanation." Heatgirl said, "Em. Where are Daisy and Frank?" Heatgirl and Iceboy looked around for Daisy and Frank, but they were nowhere in sight. They also saw the circus was gone. Iceboy said, "And where's the circus?" Clownpira and her crew were on the road driving to the next town. Clownpira said, "We have a couple of problems with our act. But I think I have just the solutions." Clownpira looked at Daisy and Frank, who they had in a circus cage, and got an idea.
The next day, Heatgirl and Iceboy saw that the town looked deserted. Heatgirl said, "This place is a ghost town." Iceboy said, "Where is everyone?" Clownpira saw them from a rooftop, took her whistle from around her neck, and blew it. Then Sungirl and Aquaboy flew into town and saw Heatgirl and Iceboy in their superhero uniforms. Heatgirl and Iceboy started to split up and look for clues around town. Then Sungirl and Aquaboy looked at each other and nodded yes to each other. Heatgirl looked on the ground for clues when Sungirl approached her. Heatgirl saw Sungirl and saw that she was dressed in a black outfit with a black mask. Heatgirl said, "Sungirl, glad to see you. What up with the black outfit?" Sungirl grabbed Heatgirl's shirt and threw her away. Heatgirl said, "What'd you do that for?" Sungirl blasted Sun Rays out of her hands, but Heatgirl dodged them.
Meanwhile, Aquaboy found Iceboy, and Iceboy saw that Aquaboy was dressed in black with a black mask. Iceboy said, "Aquaboy, thank goodness you're ok." Aquaboy said, "Better than ok; I'M GREAT!" Iceboy said, "Wait, don't you remember me." Aquaboy walked up to Iceboy. Aquaboy said, "All I remember is I hate superheroes." Aquaboy jumped on Iceboy and kicked him away. Heatgirl and Iceboy re-grouped, and so did Sungirl and Aquaboy. Heatgirl said, "Whatever Clownpira did to them, we're gonna un-do it." Iceboy said, "But in the meantime, EAT MY SUPERHERO DUST!"
Sungirl used her Laser Vision on Heatgirl, but Heatgirl matched it with her Heat Vision. Sungirl and Heatgirl couldn't take the stress when both hit, so they stopped. Meanwhile, Iceboy kept trying to hit Aquaboy with his ice, but Aquaboy blew it back at him with his mighty wind. When his ice came back at him, Iceboy made a giant pillar rise out of the ground, breaking all the ice coming at him. Heatgirl got an idea since one one-on-one fighting was getting them nowhere. Heatgirl made a fire lasso from one of her fingers, swung it around, and lassoed both Sungirl and Aquaboy. Then Iceboy held Heatgirl's hand, closed his eyes, and started to glow blue. Heatgirl began to turn blue, too, and so did her lasso. Then, her loop became supercharged with fire and ice, strengthening the ropes. Then they tied Sungirl and Aquaboy together and locked them in their basement. Heatgirl said, "Those ropes we tied them in are practically superpower-proof. If they try to escape, they'll get shocked. And the door is locked, so they can't get out anyway. Now let's go get Clownpira."
Heatgirl and Iceboy were sitting in a tree when they found Clownpira's circus tent in New York City. Iceboy said, "Clownpira should be in there." Heatgirl said, "Then let's go." Heatgirl tried to climb down from the tree, but Iceboy grabbed her arm. Iceboy said, "Wait!" Heatgirl said, "We can't just rush in there. Clownpira gets her power when people laugh, so if we want to stop her, we will have to pull some tricks of our own." Heatgirl and Iceboy wore regular clothes over their superhero uniforms and removed their masks. Then they walked into Clownpira's circus tent and saw her and the other clowns singing a stupid song and dancing like fools.
The audience laughed at how funny they were, and Clownpira absorbed the laughter to make her more powerful. When they were ready, Heatgirl and Iceboy removed their regular clothes and returned to their superhero uniforms. Then Heatgirl set the stage on fire and broke it down. When Clownpira climbed out, she snapped her fingers, and all four cronies arrived. All four circus freaks ran up to Heatgirl and Iceboy and surrounded them. Iceboy tried punching Sam, but Sam grabbed his arm and twisted it. Then he started to smell smoke and looked behind him. Sam then glanced behind him and saw Heatgirl set his pants on fire. Sam then let go of Iceboy, and Iceboy blasted Sam with his ice and put out Heatgirl's fire. Iceboy then reshot Sam and froze him in solid ice. While fighting, the audience laughed at them because they thought it was part of the show and kept making Clownpira stronger. Danny then whipped Heatgirl, but Heatgirl grabbed it. Heatgirl said, "On the other hand." Heatgirl set the whip on fire and burned Danny's hands. Then she shot him away with her Heat Beam.
Meanwhile, Iceboy and Lina were fighting on the tightrope. Lina and Iceboy kept trying to knock each other off the tightrope until they jumped and landed on different sides of the trapeze. Lina stood on one foot and said, "I'm waiting. Show me your moves." Heatgirl said, "How about I show you mine?" Heatgirl cut the tightrope with her Heat Vision, and Lina fell off it while Iceboy floated in the sky. Then Iceboy flew down to save Lina and caught her in his arms. Once he set her down, Iceboy gave Lina a knuckle sandwich and knocked her down. Then, a stampede of animals came into the center ring and went after Heatgirl and Iceboy. Iceboy then froze the ground with his powers and said, "Time for you guys to cool off." Danny said, "Hey, my animals can't move." Iceboy flew by Danny and said, "I know. I froze them to the ground. I call it my portable ice rink. And I call this a penalty kick." Iceboy then kicked Danny hard, and he got knocked out. When they finished, Clownpira saw Heatgirl and Iceboy still standing while her cronies were knocked unconscious, and their worlds were spinning. Heatgirl said, "Four up, four down." Iceboy said, "Now it's time to catch Clownpira."
Clownpira was performing in the center ring when Iceboy flew to her and hit her at the tent's top. She landed at the top of the trapeze when she got up there. Iceboy said, "Hey, mind if we cut in?" Clownpira looked down, saw it was Heatgirl and Iceboy, and got mad at them. Then she flew down and landed on her feet. Clownpira said, "Hit the shower, Fiddlestick." Clownpira took off her hat. Clownpira said, "I don't do outside performances." Clownpira threw her hat at Heatgirl and Iceboy, and it turned into a power drill. Then Heatgirl blasted it with her Heat Vision and destroyed it. Clownpira walked up to the center ring and got ready to do another performance. Then Heatgirl cut the lion's leash with her fire, and Clownpira saw they were back. Heatgirl said, "Sorry, no more solos in this crowd. Have you considered duets?"
Clownpira jumped, and so did Heatgirl. Heatgirl blasted Clownpira with her fire, but Clownpira sprayed it with a water gun and put her out. Iceboy tried to freeze her with his Ice Beam Eyes, but Clownpira jumped, and he froze Heatgirl instead. Heatgirl used her fire and all her strength to break free. Clownpira was annoyed with Heatgirl and Iceboy, so she dropped her box of jokes, and her hands started to glow purple. Then she screamed and blasted them with her powers. When her powers hit Heatgirl and Iceboy, she trapped them in a giant purple bubble. Heatgirl and Iceboy tried to escape, but they couldn't, even with their powers. Clownpira said, "Hear that? They're laughing at me ALL OVER THE WORLD!" Clownpira's hand glowed purple, and she grew more muscular from all the laughter. Clownpira said, "My revolution WILL last forever." Iceboy said, "She's too strong. If we could stop the crowd from laughing." Heatgirl said, "That's it! I have an idea."
Heatgirl and Iceboy held hands, snapped fingers, and set Sungirl and Aquaboy free. Since the door got locked, Sungirl and Aquaboy smashed through the ceiling and left the house. When they got to the circus, they came in through the top of the tent. While they were in the tent, they saw Heatgirl and Iceboy. Heatgirl said, "Ya want us, come and get us." Sungirl tried blasting them with her Sun Rays, but instead, she hit the tent and set it on fire with her. Then Aquaboy made a giant hurricane, but the bubble still protected them, and Aquaboy worsened the disaster. Iceboy said, "What were you thinking?" Heatgirl said, "Trust me." The fire and hurricane Sungirl and Aquaboy scared everyone worldwide, making them stop laughing and start screaming. Clownpira said, "What? No, stop." The crowd left the tent screaming in terror, and Heatgirl and Iceboy got set free. Sungirl and Aquaboy returned to normal, and Clownpira became powerless.
The Justice Brigade all walked up to Clownpira, and she looked at them. Clownpira said, "The audience may be gone, but I still have my power." Clownpira tried to use her powers on The Justice Brigade, but they didn't work. Clownpira said, "I'm powerless?" Iceboy said, "And we're not." Then Sungirl blasted Clownpira with her Sun Rays, Heatgirl hit her with her Heat Vision, Iceboy froze her with his Ice Beam Eyes, and Aquaboy blew her into the police car with his winds. When they got outside, they watched Clownpira and the circus freaks get carried off to jail. When she left, her circus tent vanished, and The Justice Brigade slapped hands. Then, the news media interviewed the Justice Brigade.
The newswoman said, "This is Petunia Cane broadcasting to you live from downtown Las Angeles. I'm here with The Justice Brigade, who saved everyone from Clownpira and her circus cronies." Petunia held her microphone up to The Justice Brigade, and they just told it as it was. Heatgirl said, "It was complicated, Petunia. But we discovered Clownpira's weakness." Sungirl said, "Aquaboy and I even fell under her control and had to fight our friends. But we still helped save everyone, even if we had to scare them away." Iceboy said, "Plus, it was the only way to break her control over you." Aquaboy said, "And now that Clownpira is behind bars, we'll return to hiding until we're needed again. But remember, you know who to call if there's trouble." The Justice Brigade flew home, returned to their everyday clothes, and waited for their next mission.
The End
