The Justice Brigade got a distress call from Tokyo, so they flew to Japan to check it out. Once they got to where the distress signal was coming from, they saw an empty alley, and nobody was there. Sungirl said, "That's weird; the distress call came from right here." Iceboy said, "So, where's the person who sent it?" A girl named Madalyn then showed up. Madalyn said, "Right here." Sungirl said, "You sent the signal? But you're not in trouble." Madalyn said, "Correct. Unfortunately, I can't say the same for you four." Madalyn brought out a gun and blasted The Justice Brigade with it. Once she did, she turned Sungirl into a younger teenager, Heatgirl into an 8-year-old kid, Iceboy into an older man, and Aquaboy into a baby. Once she finished, she took her gun and flew away, laughing evilly.
The Justice Brigade looked at themselves on the side of a glass building and saw what Madalyn did to them. Heatgirl said, "We're younger." Ice Man said, "Speak for yourself." The rest of The Justice Brigade saw that Iceboy was now older. Sungirl said, "We got to get that ray and get us back to our normal ages. Ice Man, you watch Heatgirl and make sure she doesn't get into trouble. I'll watch Baby Aquaboy and make sure he stays quiet and happy." Ice Man held onto Heatgirl's arm and said, "Fine." Then Sungirl picked up Baby Aquaboy, and Baby Aquaboy started to cry. While The Justice Brigade was trying to plan to keep an eye on the kids and save the world, Madalyn flew to the prison. Then she broke into it, and three villains inside it saw her shadow. Madalyn said, "Mind if I cut it?" Then she broke Insect Princess, The Speedster, and Techno out of prison, and they joined up with her.
After Madalyn broke the villains out of jail, Sungirl flew Ice Man to the prison, and Heatgirl flew Baby Aqua Boy there. Heatgirl said, "Are you sure I should be following you?" Sungirl said, "I'm the leader; I know best. And if you don't do as I say, you're grounded." Sungirl and Heatgirl landed, and when they did, they saw the villains breaking out of prison. Sungirl said, "According to my calculations, you still have a year's worst of a sentence." The villains then looked at The Justice Brigade and laughed at them. Insect Princess said, "Nice baby, Prom Queen." The Speedster said, "Are you going to stop us, gramps." Techno said, "What about you, little missy?" Sungirl gave Aquaboy to Iceboy and said, "Don't let him out of your site."
Sungirl stood ahead of the villains and said, "Now, we can do this the easy way or the hard way." Insect Princess then shot stingers at Sungirl, and one tore part of her costume and stung her. Sungirl said, "I guess that's the hard way." Insect Princess then flew directly down towards Sungirl, but Sungirl put up her Sun Shield, and Insect Princess got hit away by it. The Speedster then ran super-fast around Sungirl and socked her, which made Heatgirl mad. Heatgirl said, "Don't be mean." Heatgirl then blasted The Speedster away with her Heat Beams, and he got shot into a building. Ice Man said, "I may be old, but you're never too old to fight for justice." Ice Man snapped his fingers and froze the ground beneath Techno's feet, and he fell to the ground. Madalyn flew out of jail and said, "Don't tell me you're losing to them." Sungirl said, "And you're next." Madalyn then levitated a few cars and threw them at The Justice Brigade. Sungirl then ran off, grabbed Heatgirl's wrist, and ran off with her so they wouldn't get hit. Seeing his friends almost killed, Baby Aquaboy cried. Then Sungirl grabbed him, rocked him, and tried to make him stop. Sungirl said, "It's OK. Baby, it's ok." While Baby Aquaboy was crying, a fire hydrant near Madalyn exploded, and the water splashed her out of the sky.
Once Baby Aquaboy saw that, he laughed and started flying. Then Sungirl flew after him and grabbed him before he took off. Sungirl then sang Baby Aquaboy a lullaby and put him to sleep, and when she looked around, she saw her lullaby put her team to sleep and the villains' team to sleep, too. Sungirl tapped Heatgirl's head and woke her up. Sungirl whispered, "Grab the baby. I'll get Ice Man." Sungirl grabbed Ice Man while he was asleep and flew him away. Then Heatgirl took off with Baby Aquaboy in her arms. Then, the police came and picked up all the villains while the villains were asleep. Once Madalyn woke up, she saw she was in a police van, and her team was sound asleep. Madalyn then used her powers to levitate the van, tilt it, and dump them all out, including the driver. Once the villains woke up, they destroyed the police van and left the driver alone. Then Madalyn grabbed The Speedster and flew off with him. Insect Princess flew after them, and Techno activated his hang glider and glided.
Meanwhile, Sungirl holding Ice Man and Heatgirl having Baby Aquaboy flew over Tokyo. They looked all over Tokyo for the weapon Madalyn used on them, hoping it would turn them back to the way they were. But while they were searching, Sungirl and Heatgirl both got shot out of the sky, and they dropped both Ice Man and Baby Aquaboy. Then they both quickly flew down and saved them just in time. Heatgirl said, "That was fun. What else can we play?" Sungirl said, "OK, who's the wise guy?" Madalyn said, "You mean wise guys." Sungirl said, "Madalyn?" Heatgirl pointed behind Madalyn and said, "Ooh, she brought her friends to play." Then Insect Princess, The Speedster, and Techno showed up. Madalyn then used her powers to break a lamppost loose and hit Heatgirl away with it. Sungirl then gave Baby Aquaboy to Ice Man and said, "Don't let him out of your site."
Sungirl then flew up to Madalyn and tried to kick her, but Madalyn used her powers to throw a piece of the sidewalk at Sungirl. Sungirl got hit out of the sky and fell to the ground. Techno threw a bomb at Sungirl, but Heatgirl destroyed it with her Heat Vision. Sungirl looked at where that blast came from and saw Heatgirl behind her. Heatgirl said, "I know it's bad to hurt other people, but as a kid, it's fun." Heatgirl snapped her fingers, and she set Techno's gear on fire. Techno said, "Stop it. You destroyed all my gear." Heatgirl said, "It's also polite to help others. So, here." Heatgirl snapped her fingers again and made the flames vanish. Then Techno's gear exploded, and Heatgirl punched him away. Insect Princess then grabbed Heatgirl and flew her high in the sky. Ice Man got an idea and held Baby Aquaboy up in the air while he spoke to him. Ice Man said, "Looks like we'll never see our young friend again." Baby Aquaboy then cried and made a gusty wind that blew Insect Princess out of the sky. Then Ice Man shot ice on the ground beneath Insect Princess's feet. Then she slipped and dropped Heatgirl. Sungirl then flew up to Madalyn while her team handled The Speedster. The Speedster ran past The Justice Brigade, but Ice Man froze the ground, and when The Speedster ran onto the ice, he slipped on Ice Man's ice and fell to the ground. Then, Insect Princess, The Speedster, and Techno piled up on each other. Madalyn saw Sungirl and waited for her to attack. Madalyn said, "Go ahead, attack me. I'll block it or send it back your way." Sungirl said, "Is that a fact?" Madalyn said, "Just try to prove me wrong." Sungirl said, "As you wish." Sun shot a Sun Beam at Madalyn, but it flew behind her. Madalyn said, "Ha, I told you you couldn't hurt me." Sungirl said, "Can't I?" Madalyn looked behind her and saw Sungirl's beam reflect off a glass building and fly back towards her. Then it shot Madalyn out of the sky, and she landed at Sungirl's feet. Sungirl said, "Ok, Madalyn. Hand over the device you used on us." Madalyn brought out her age ray and gave it to Sungirl. Sungirl then set the beam for their regular ages, shot her team with it, and returned them to normal. She then blasted herself and returned to herself to her usual self. Sungirl then threw the beam at the ground and destroyed it. After The Justice Brigade defeated Madalyn and her crew, the police came, got them, and took them to jail. Then, The Justice Brigade flew back home and waited for their next mission.
