The Justice Brigade was exploring space because Heatgirl wanted to show her team the places she had saved in the past and how much fun it was to fly through the galaxy. Sungirl, Iceboy, and Aquaboy flew in space suits, but Heatgirl didn't need one since she was from space. While exploring, The Justice Brigade visited different planets. They first visited a blue planet, and upon arrival, they found that the entire place was covered in ice and snow. Sungirl said, "Where are we?" Iceboy said, "I don't know, but I like it. This place fits me and my powers perfectly well." Heatgirl said, "This is Iceburgia, the planet of snow and ice." Then Sungirl and Aquaboy were blasted with Ice beans and frozen in ice. Heatgirl and Iceboy looked at the source of the beam and saw a snow monster. Heatgirl said, "Oh yeah. And the planet of the snow monsters. You hold him off, and I'll get Sungirl and Aquaboy out. Iceboy flew up to the snow monster and tried to punch him, but he missed. While Iceboy fought the snow monster, Heatgirl blasted and unfroze Sungirl and Aquaboy with her Heat Beams. The snow monster then used his powers to shoot icicles at Iceboy, but Iceboy did the same thing to the snow monster. Iceboy's icicles hit more enormous icicles above the snow monster and made them drop on him. Then, the giant icicles surrounded the snow monster, imprisoning it. The snow monster's icicles hit a cliff above Iceboy, and the snow dropped and landed on Iceboy. Heatgirl then used her Heat Beam Eyes to melt the snow, and the Justice Brigade flew off the planet before the snow monster got free.
After getting off Iceburgia, the Justice Brigade flew to another planet. What they didn't know was that Delilah was spying on them. Delilah said, "Ah, Heatgirl is exploring space like she did many years ago. But this time, she's doing it with her annoying friends." The Justice Brigade kept soaring through space while Delilah watched them. Heatgirl said, "See. I told you guys flying in space was fun." Delilah watched The Justice Brigade laugh as they soared through space. They landed on another planet, took their helmets off, and looked around. Aquaboy said, "Cool. It's Halloween." Heatgirl said, "No. It's Transylween. People here are all monsters and ghosts. Some are kind, and others are mean. But we shouldn't stay for long. This place has a monster spell on it." Iceboy asked, "Oh, come on, how bad could it be?" Sungirl's skin started to turn green, Heatgirl's legs began to get wrapped in bandages, Iceboy grew fangs, and Aquaboy's arms got covered in hair. Aquaboy looked at his arm and saw fur everywhere, and his hands were growing claws. Aquaboy said, "Cool. Werewolf arms." Heatgirl said, "If we don't get off this planet, you'll become a real werewolf, I'll become a mummy, Sungirl will become a witch, and Iceboy will become a vampire." Sungirl walked into town and asked, "Are you people crazy enough to turn your guests into monsters?" Sungirl then got caught in a trap, and the citizens surrounded her. Sungirl said, "Let me go. I'm just visiting; I mean, I don't do you any harm. I'm not even a witch." Delilah then showed up and said, "Don't listen to her. She is a witch, which means we are in harm." The citizens of Transylween then tied up Sungirl and tried to kill her by throwing her in their giant, fiery jack-o-lantern. Aquaboy said, "Well, she needs me." Aquaboy hurried to Sungirl's rescue, and Delilah said, "Right on time." Delilah pointed at Aquaboy and said, "Behold. The evil witch has a werewolf rescuer." Delilah's skin began to wither, and she started to turn into a skeleton. Delilah looked at her arms and said, "Wow, bone arms." Heatgirl then blasted Delilah away with her Heat Beam while the citizens threw Sungirl into the flaming jack-o-lantern. Aquaboy then used his powers to blow out the fire and save Sungirl. He scaled the jack-o-lantern, jumped in it, and got himself and Sungirl out. After Aquaboy saved Sungirl and Heatgirl had stalled Delilah, the Justice Brigade put their helmets back on, flew off Transylween, and regained their regular bodies. Then they tried flying back to Earth, but Delilah chased them. Sungirl said, "We can't lead her back to Earth. We're going to have to lead her somewhere else." Heatgirl said, "I know just the place."
Heatgirl flew ahead of her team, and her team followed her while Delilah followed them. Heatgirl saw a fire planet and said, "Here it is." The Justice Brigade flew over the fire planet, and so did Delilah, but the volcanoes on the planet fired at her ship. Then, her ship got hit with some of the pumice from the volcanoes on the planet. Since Delilah was still following them, the Justice Brigade flew down to a barren planet. Delilah then landed her ship on the same planet and disembarked. Delilah said, "You four will remain here for the rest of your lives." The Justice Brigade flew off the planet, but Sungirl stayed for a minute. Sungirl said, "What was that about us staying?" Sungirl flew off with her team, and Delilah returned to her ship and chased after The Justice Brigade. The Justice Brigade flew to a yellow planet, and Delilah followed them there.
Once they arrived, they took off their helmets and saw that the place looked like ancient Egypt back on Earth. Heatgirl said, "Welcome to Egypto. The desert planet and the citizens are like what you can find in Egypt back on Earth." Heatgirl pointed across the planet, and The Justice Brigade saw mummies walking on one side and cats walking on the other. Delilah landed her ship, got off it, and searched for The Justice Brigade. Once she found them, they got into a fight.
Delilah used a laser built into her armor to take out Heatgirl. Then Sungirl destroyed her laser with her Sun Beam. While fighting, the citizens of Egypto came to watch. They saw Delilah shoot Sungirl with a rocket, but Sungirl managed to avoid her attack. Then Iceboy froze Delilah's feet to the ground, and she struggled to get out. Aquaboy then punched Delilah since she couldn't move. Once Delilah was down, the mummies and cats clapped for The Justice Brigade. While they were getting applauded, Delilah took a laser and shot The Justice Brigade with it. After blasting The Justice Brigade, Delilah ran onto her spaceship and tried to escape. Since Delilah was getting away, the Justice Brigade put their helmets back on and flew up into space after her. Once they left, the citizens of Egypto cheered for them while they flew away.
The Justice Brigade flew after Delilah, and Delilah had them on screen. Sungirl shot an energy ball at Delilah's spaceship, but it bounced off her shield. Sungirl said, "What? Your ship is shielded?" Delilah activated her spaceship's speaker and used a microphone to communicate with The Justice Brigade in space from inside her ship. Delilah said, "That's right. I'm more than ready for any of your attacks. But you can't say the same about me." Delilah pushed a button on her ship, brought out its cannon, and shot cannonballs at The Justice Brigade. The Justice Brigade avoided her first attack, but they saw that the cannonball she shot was headed for deep space. Sungirl said, "Heatgirl, you get rid of that ball. We'll handle the cannon." Sungirl gave Heatgirl her jetpack to make her fly faster. Then Heatgirl activated the jetpack Sungirl had given her and hurried after the cannonball that had been fired. Delilah then shot another cannonball at The Justice Brigade, but Iceboy froze it with his Ice Beam, and Sungirl destroyed the ball and the cannon with her Sun Beams.
Meanwhile, Heatgirl caught up with the first cannonball Delilah shot and destroyed it with her Heat Vision. After blowing up the cannonball, Heatgirl flew back to her team. Heatgirl said, "Ok, how will we get aboard Delilah's spaceship without suffocating anyone since there's no air in space? Sungirl said, "There's one thing we could try." Sungirl put a light ball around them and made them disappear. Then they reappeared inside Delilah's spaceship. Then, they all took off their helmets since they were safe inside Delilah's spaceship. Heatgirl said, "Hey, Delilah!" Delilah looked behind her and saw The Justice Brigade. Delilah said, "Uh oh." The Justice Brigade flew up to Delilah, beat her up, and then Heatgirl tied her up. After beating Delilah, the Justice Brigade handed her over to the space police. Delilah said, "I'll be back, Justice Brigade, and next time, you're mine." Heatgirl put a smirk on her face and said, "We'll see about that." The Justice Brigade then put their helmets back on, soared through space to get home, and had fun doing so.
