History: <30th Century> Gim Allon joined the Science Police Academy, and when he took a vacation from training to travel to Mars he was exposed to a radioactive meteor that gave him superhuman powers. As Colossal Boy he became an early member of the Legion of Super-Heroes. 

(Adventure Comics I #304) - Colossal Boy and the Legion were set to have their annual vote to elect a new leader, and Saturn Girl was the first to arrive at the Clubhouse. A crystal capsule sent from the Trylop Council of Mernl dropped from the sky warning that their computers predicted a Legionnaire would die using their powers during an upcoming invasion of Earth by Zaryan the Conqueror, and Saturn Girl resolved to sacrifice herself to protect her fellow Legionnaires. She used her thought control to nudge the Legion into electing her leader, then used a rainbow bar from their treasury to make medallions with her face printed on them, and demanded every Legionnaire wear one. She demanded the Legionnaires demonstrate effective use of their powers, and was able to temporarily duplicate each member of the Legion’s powers using the medallions they wore, and proceeded to forbid them for using their powers or going on missions during a probation period because she declared they were not using their powers properly. When Zaryan began his invasion of Earth she responded, and warned the other Legionnaires not to follow her because they were on probation. The Legion thought she’d gone mad with power, but Mon-El had observed her actions from the Phantom Zone, and knew her motivations. Sunspots interfered with him communicating with the Legion, but when they lifted he filled in Lightning Lad on the situation, and he flew into space, determined to keep Saturn Girl from sacrificing herself. He blew up Zaryan’s ship with his powers, but was fatally shot with a freeze-ray. The Legion honored him by placing him in a glass coffin with lightning generated over it by a perpetual motion device, and his funeral was attended by Superboy, Supergirl and Lori Lemaris. The Legion placed a statue of Lightning Lad in their Clubhouse as a tribute to the first Legionnaire killed in action.

(Adventure Comics I #305) - The Legion still mourned Lightning Lad, but had to fill the spot his passing left on the roster, so they held an open audition. Antennae Boy of Grxyor could use his ears as an antennae to tune into any radio station from Earth’s past present or future, but the screeching sound of radio programs blaring over each other drove the Legion nuts, and he admitted he couldn’t control his powers. Dynamo Kid was a reporter hoping to do a story on the Legion, and rigged a device to make it appear as if he had the same powers as Lightning Lad, but the Legion easily saw through his ruse. Marvel Lad demonstrated several of the same powers as Superboy, making the team suspicious. A metal-detector revealed he wasn’t a robot, and he proved he wasn’t Superboy in disguise by handling a piece of Kryptonite kept in the Legion Clubhouse. Cosmic Boy decided to give Marvel Lad a number of initiation tests before letting him on the team. He had Marvel Lad retrieve fluvium, which Brainiac 5 needed for his lead-poisoning antidotes he was developing to cure Mon-El, and Marvel quickly brought some back from a distant galaxy. For his next test fought a feeding Sun-Eater, a being that roamed the galaxy absorbing the heat and energy of suns, and made it flee by blasting it with his heat-vision, which was hotter than a sun. Marvel was told to clear the planet Brogg of space monsters so it would be safe to use as an emergency landing spot for space pilots. The monsters turned out to be illusions created by a 3-D generator. Marvel smashed it and found stolen treasure underneath it, realizing the charade was created by space pirates looking to protect their booty. For his final test Marvel Lad had to create a new element, and by crushing gold, silver and iron into powder and rubbing his hands at superspeed to vibrate the molecules of the three elements he formed a bar of element 152, an anti-gravity metal. Marvel Lad was accepted into the Legion, and pulled off the mask he wore, revealing himself as Mon-El. The day before Brainiac 5 had him test his latest antidote, but told him to wait a day to make sure its’ effects were permanent before revealing himself to the Legion, not wanting to get their hopes up as they had before when Brainiac came up with a cure that turned out to be temporary. Mon-El took one last trip to the Phantom Zone to tell off the Kryptonian criminals who’d tormented him for centuries, and reminded them that good always triumphed over evil. Mon-El was overjoyed that Brainiac had finally cured him, but his spirits were dampened by the passing of Lightning Lad, and vowed to find a way to revive him using Daxamite super-science.

(Adventure Comics I #306) - The Legion held try-outs, and had to reject several well-meaning but unsuited applicants, including Polar Boy, Night Girl, Chlorophyll Kid, Fire Lad and Stone Boy. The rejects met up and were encouraged by Polar Boy that even though they weren’t Legion material, they could still use their powers to help people. They formed the Legion of Substitute Heroes, vowing to help people and, if need be, the Legion of Super-Heroes in their time of need. They built their own clubhouse in the side of a mountain as well as a spaceship and Science Police monitoring system. They got a warning about giant evolved sea creatures that had escaped from the Ocean Research Laboratory, and were quick to respond, but the LOSH were already on the scene wrangling the beasts. The next Science Police alert came when scientists who’d built a domed city in the Arctic went rogue. They secretly built an atomic power plant under the dome, propelling the city into space, and delivered an ultimatum that they’d use the advanced weaponry they’d built to attack Earth unless they were given tribute. The Substitute Heroes flew into space, but Sun Boy of the Legion streaked through space near the domed city, and fearing they were about to be hit by a meteorite the scientists piloted their city back to Earth where they were apprehended by Colossal Boy and Cosmic Boy. Robot-ships attacked Earth and Polar Boy offered the Legion back-up, but Brainiac 5 refused him, saying the mission was too dangerous for untrained civilians. The Substitute Heroes’ anxieties finally got to them, and they decided they were no help as a team after all and prepared to disband. Chlorophyll Kid spotted seeds that had rained down from space, and used his plant growth powers on one. The seed grew into a plant man that attacked him, and the Substitute Heroes defeated it, and Fire-Lad incinerated the rest of the seeds. They learned from their monitor system that the seeds had come from a distant planet that had also sent the robot-ships. The robot-ships were meant to divert the Legion while the planet rocketed more seeds to Earth to conquer the planet. The Substitutes traveled to the planet, found the warehouse storing millions of seeds, and Chlorophyll Kid used his powers to prematurely grow them to plant men. The planet was now burdened with a population explosion, and had to cease its’ plans of invasion. The Substitutes decided to stay together after all, and were pleased to keep their victory a secret amongst themselves, and attended a parade for the Legion celebrating their defeat of the robot-ships.

(Adventure Comics I #307) - Space pirate Roxxas and his crew wee looking for a valuable target, and during their search they raided the planet Oranz, stealing all their cold light globes. The Legion responded, with Sun Boy heating a mountain to white-hot temperatures to provide light for the natives until they could produce more cold light globes to light their cities. The Oranz shot down one of the pirate’s rocketships, which Brainiac 5 examined, declaring it capable of faster-than-light-travel. He immediately went about replicating the technology so the Legion could pursue Roxxas. With several members on offworld missions the Legion conducted an emergency membership drive. Jan Arrah of Trom, said he had an amazing power, but couldn’t reveal it to all of them. They assumed he had a good reason for his conditional application, and he showed it to Saturn Gir, who promised not to reveal his power, but assured the Legion he’d be a worthy member. Dubbed Mystery Lad, he accompanied the Legion using the faster-than-light rocketships Brainiac 5 duplicated to the waterworld of Vuruna, where Roxxas and his men had looted valuable colored pearls. Roxxas dropped z-bombs on the pontoons of a city in Vuruna, and Cosmic Boy used his magnetic powers to keep the city afloat until repairs could be made, but Roxxas managed to escape. Saturn Girl used her telepathic powers to follow the pirates to a dead world, and Mystery Lad helped them escape an ambush., The captured pirates recognized Mystery Lad, who looked guilty on meeting them, and Invisible Kid suspected he was secretly a space pirate. The Legion continued to pursue Roxxas and his crew, and Mystery Lad got out in front of them, surrendering himself to the pirates. They’d raided his homeworld because the residents were capable of transmuting one element to another, and they planned to force the natives to turn lead into uranium so they could create a doomsday weapon, the threat of which would let them conduct unopposed raids across the universe. The residents of Trom fought back, and were all killed except Jan, who fled, and Roxxas had pursued him ever since, which was was he was hiding the nature of his powers. Jan said he’d rather die than help them, and turned the hull of their mothership into gas. The pirates had oxygen helmets and fled, only to be captured by the Legion. Invisible Kid, still suspicious of Jan being allied with the pirates, had followed him onboard Roxxas’ ship, and gave him an oxygen helmet, saving his life. Cosmic Boy welcomed Jan as a full member of the Legion, dubbed him Element Lad, and promised that the nature of his powers would still be kept a secret to everyone but the Legion.

(Adventure Comics I #309) - The Legion furthered their education by taking classes via closed-circuit TV so they’d never miss a lecture no matter where they were in the galaxy. Colossal boy was defending a planet in the Rox-Ul galaxy from an alien invasion, but took the time to take class notes..

(Legion of Super-Heroes III #1) - Lightning Lord formed a new Legion of Super-Villains, with each of them swearing a blood oath to kill at least one Legionnaire. Colossal Boy, who’d only ever lived at home, and then at Legion hq, got an apartment with Yera. Yera was worried they’d face discrimination, since some landlords expressly forbid Durlans, but they managed to find a nice place. They settled into their new place, and Colossal Boy learned from the news that his mother Marte Allon had resigned as Earth President.

(Legion of Super-Heroes III #2) - Light Lass awoke in chains in a cell, and Lightning Lord promised his sister he wanted to help her, not hurt her. He said he loved her, and all the proof she needed was that she was still alive. He asked her to join the Legion of Super-Villains and help him kill Lightning Lad, saying he’d been talking to the storm, and the storm had assured him she’d come to him. Light Lass turned him down, saying he was more insane than ever. Element Lad tracked the resurgence of the Legion of Super-Villains across several planets, brief his team, and realized he was in for a major test of his leadership. The League of Super-Assassins joined with the Legion of Super-Villains, and Lightning Lord sent them and Magno Lad to M-17W, a manufacturing center in the galactic core, to steal the plant’s fusion powerspheres. Shvaugn Erin alerted the Legion, and Dawnstar and Wildfire responded first, but Lazon gave Dawnstar radiation sickness with his light powers, and Magno Lad ripped Wildfire’s containment suit apart. Shadow Lass, Mon-El, Ultra Boy, Chameleon Boy and Timber Wolf arrived as support, but the villains escaped using a dimensional rift opened by Zymyr. Shadow Lass treated Dawnstar, while Chameleon Boy brought Wildfire a new containment suit. They pursued the villains, but were ambushed by Terrus, who attacked their spaceship with a meteor shower. Cosmic Boy checked in with the Legion Academy, and alerted Lightning Lad and Saturn Girl about the danger. They were on Medicus One, with Saturn Girl receiving prenatal treatment and her delivery date fast approaching. Lightning Lad worried about the safety of his sister, not knowing she was already in captivity. Zymyr opened a spacewarp that stole the polymer screen around Earth that served environmental functions and controlled space traffic. Element Lad, Lightning Lad, and despite everyone else’s objections, Saturn Girl, responded. Saturn Girl went into labor, and Tyr was disappointed to be fighting a prgnant woman, but contented himself with the fact that she’d be easy to kill. Zymyr ended the confrontation, warping his teammates away, and Element Lad and Lightning Lad rushed Saturn Girl to the Medicus One Maternity Ward. Dr. Gym’ll told Lightning Lad he’d been paging him, and that if he wasn’t planning on pulling any more moronic stunts it was time to get in the delivery room. Element Lad, who’d been pacing back and forth in worry, fainted. Queen Projects and Karate Kid flew back to Orando after their honeymoon, but the Legion of Super-Villains were waiting for them, and Magno Lad, Hunter and Mist Master brought their spaceship down. They took the heroes legion rings and sent out the alarm signal, saying the Legion would come running to their own doom.

(Legion of Super-Heroes Annual I #3) -

(Legion of Super-Heroes III #3) - Dawnstar, Wildfire, Mon-El, Ultra Boy, Chameleon Boy, Timber Wolf, Phantom Girl, Shadow Lass and White Witch set course for Orando, but were being followed by Terrus and Zymyr. Zymyr opened a spacewarp that warped in most of the Legion of Super-Villains to ambush the Legionnaires. On Earth Cosmic Boy agreed to keep watch on the planet while Element Lad assembled the rest of thew Legion to fly a ship to Orando. Cosmic Boy was worried about Element Lad devoting all their resources to Orando, but trusted his judgment. He was thankful when Night Girl sent a video message offering the help of the Legion of Substitute Heroes. Projecta and Karate Kid were chained in a cell next to Light Lass, and Lightning Lord visited her to again plead with her to join him, saying she’d join his Legion in a passage to a new world where they would rule. She made it clear she’d rather die, and he called her a traitor to her own blood, grabbing her and shocking her before walking off disgusted, saying he no longer had a sister. Dream Girl woke in her crashed ship on Orando, finding Star Boy and Shrinking Violet still unconscious. She recognized Projecta’s castle from her vision where a Legionnaire was die, and she was ambushed by Hunter and Silver Slasher. Dawnstar and her teammates were in danger of being overwhelmed by the Legion of Super-Villains until element Lad and his reinforcements arrived. Nemesis Kid, Cosmic King, Neutrax and Ron-Karr placed the polymer screen around Orando, and hooked it up to their stolen powerspheres. They planned to warp Orando away to another world where there was no Legion of super-Heroes. Nemesis Kid had always been drawn to the powerful, and couldn’t wait to arrive in a new world where he’d be the supreme power, planning on declaring himself the emperor of a universe. Zymyr was prepared to warp the planet, but Nemesis Kid wanted to give his Legion a little more time battling the Legion of Super-Heroes to see if they could kill any of them before they left. The Legionnaires were winning, so Nemesis Kid gave the order to warp away the Legion of Super-Villains, inadvertently taking some of the Legionnaires with them, and warped Orando to a space between dimensions.

(Legion of Super-Heroes III #4) - Tyr was furious that Nemesis Kid had kept him away from battle, and reminded him of the blood oath they’d sworn to kill the Legion. Nemesis Kid reminded him that Zymyr’s warp had captured Ultra Boy, Phantom Girl, Element Lad, Chameleon Kid and Shrinking Violet, who sat in prison cells alongside Projecta, Karate Kid and Light Lass. Nemesis Kid said that finding and conquering new worlds was their priority, but Tyr demanded satisfaction. Nemesis Kid said he could take one of their spaceships and Zymyr would warp it back to the space where Orando once orbited so he could continue to fight. Tyr asked who’d join him, and Terrus, Titania, Silver Slasher and Hunter followed him. Silver Slasher and Titania claimed Blok for themselves, still bitter that he’d betrayed their League of Super-Assassins. In the space around Orando Brainiac 5 worked out how the LSV stole the planet and told his fellow Legionnaires his conclusions about their methods and motives. The disruptors Light Lass was manacled in exploded, and she could once again use her powers. She woke Karate Kid, who freed himself from his disruptors through sheer force of will, and he freed his wife and the other captive Legionnaires. Light Lass snuck aboard Tyr’s ship, and found that either the destruction of her disruptor manacles, the shock she’d received from Lightning Lord, or both, had restored her powers. She unleashed a massive lightning blast on Tyr and his allies, shocking them unconscious, and took control of the ship. Dream Girl, acting as deputy leader with Element Lad on Orando, called Cosmic boy to check in on Earth. Cosmic boy now had the back-up of reservists Bouncing Boy and duo Damsel, the Legion of substitute Heroes and the Legion Academy. On Orando the freed Legionnaires tried to destroy the powerspheres on the polymer screen around Orando, hoping that would return the planet to its’ proper spacetime, but they were overwhelmed by the LSV guarding the screen. Projecta pleaded with Karate Kid to save her planet, and he confronted Nemesis Kid in one-on-one combat. Nemesis Kid said he knew they’d end up fighting to the death from the day they’d first both joined the Legion of Super-Heroes. Nemesis Kid adapted Karate Kid’s skills and mercilessly battered him, but Karate kid refused to give up. Nemesis Kid demanded he lay down and die, but every time he knocked Karate kid down, the hero got back up. He’d sustained life threatening injuries, but Karate Kid managed to wrest his flight ring back from Nemesis Kid, told Queen Projecta he’d always wanted to die in battle, and flew into one of the powerspheres, causing it to explode and killing himself in the process.

(Legion of Super-Heroes III #5) - The Legionnaires waiting in the space where Orando once was were met by Gigi Cusimano, who recalled them to Earth by orders of the Science Police, and Brainiac 5 protested that the order was irrational. Gigi flirted with Sun Boy, and negotiated with Dream Girl, who convinced her to allow Brainiac 5, Sun Boy, Shadow Lass and Mon-El to stay put should Orando return. Queen Projecta cradled Karate Kid’s charred corpse as the Legion of Sup-Villains surrounded her. Projecta raged at the villains, saying they’d ravaged her planet and killed her husband, and demanded they leave Orando. Nemesis Kid told his teammates to stay back, saying he wanted to be the one to kill her. Light Lass observed the events from Orando from her ship, and, unwilling to see another teammate die, changed course back to the planet. Light Lass charged into battle against the Legion of Super-Villains, but Lightning Lord demanded they leave her be, because she was his sister, and because she’d betrayed him he had the right to kill her. Light Lass almost pitied her insane brother, but after a fierce battle she soundly beat him. The rest of the LSV prepared to attack her when her teammates stranded on Orando came to the rescue, with Element Lad disabling several of the LSV by changing the air around them to helium, causing them to lose consciousness Nemesis Kid told Zymyr to call in the rest of their team as backup, and Projecta assured him she was going to kill him. Element Lad disabled Ol-Vir by turning his clothes to lead, poisonous to Daxamites. The rest of the LSV were soon overwhelmed, and Mist Master, Ron-Karr and Radiation Roy decided the fight was already lost, and boarded Zymyr’s ship, warping themselves back to the space around Orando. Zymyr decided that their dream of finding new worlds to conquer was never to be, and said he would no longer be burdened by humans, and prepared to warp away. His spacewarp accidentally took Light Lass and Lightning Lord with him back to his homeworld Gil’Dishpan. Projecta created illusions of Hell, telling Nemesis Kid that was where he belonged. His power dispelled her illusions, but she Projecta didn’t back down, saying she was the descendant of wizards and kings, and needed only her own strength to finish him. Projecta snapped his neck, and told her stunned former teammates that as queen it was her right to execute a condemned man. The villains aboard Zymyr’s ship crashed and were easily captured by the Legion, and Brainiac 5 hoped to repair the ship to brink back their stranded teammates, but Gil’Dishpan technology defied all known physics and his own super-genius. Projecta held a funeral for Karate Kid, and told her subjects she blamed herself for allowing such evil on her world. The remaining members of the Legion of Super-Villains were contained in one of Zymyr’s spheres, and she instructed the Legionnaires to enter the remaining sphere. Projecta said Orando was ill-suited for modern times and contact with other planets, so she’d use Zymyr’s machine to find new worlds where Orando and her citizens could be left in peace, and told the Legion to never seek her out. Orando warped away, and the Legionnaires hoped their teammates would capture Zymyr and rescue them. Esper Lass sent a telepathic message to the Legionnaires, mocking them. She’d penetrated Zymyr’s mind, and knew how to use his spheres, allowing her to warp herself and her teammates away while the Legionnaires were stranded in their sphere between dimensions.

(Legion of Super-Heroes III #7) - Lightning Lass demanded Dream Girl and the Legion readmit her to the team despite their rule against duplicate powers, and she said she didn’t want Dream Girl to change her powers again. Dream Girl responded that  she wouldn’t think of tampering with her powers again, as she knew better, and told Lightning Lass she was not up on current events, because her brother was on leave taking care of his newborn son. Lightning Lass was in shock, but overjoyed that she was an aunt. Cosmic Boy mused that Lightning Lass replacing her brother on the team fell right in with his plans, and he told Wildfire he had some ideas to discuss with him. Colossal Boy helped his mother pack up her belongings so she could return home. He said he was just getting used to the idea of her as President, and she responded that she felt the same way, which was part of the reason she resigned. Chief Zendak sent out an alert asking for Legion assistance. The remaining members of the Legion of Super-Villains were approaching Earth, and he wanted them arrested before landing. Colossal Boy was quick to respond. The rest of the Legion met with Shvaugn Erin and prepared for takeoff in their hangar. Timber Wolf confronted Lightning Lass about ghosting him since she left the Legion. She said she’d cut ties with him because he’d decided the Legion was more important than their relationship. He pointed out that she just rejoined the Legion, and she replied that she came to that decision after soul-searching and a journey of self-discovery that he chose not to join her in, and made it clear she had no more romantic feelings for him.

(Legion of Super-Heroes III #9) - The Legion of Super-Heroes were reunited with their members lost in Limbo, and threw a huge party. Shrinking Violet wanted a word with Yera, and when Colossal Boy said anything she had to say to his wife she could say in front of him, but Yera said she could take care of her own affairs. Shrinking Violet begrudgingly accepted that Yera was an innocent dupe when she impersonated her, but if Yera ever took her form in public or private there would be trouble between them.

(Legion of Super-Heroes III #10) - The Worldcomp computer chose the candidates for the next President of the Earth, and Colossal Boy, Yera and his parents celebrated Marte’s last day as President. She said she looked forward to going back to teaching at university. The Khunds wanted to spark a war with Earth, and sent an assassin to kill Marte. Colossal Kid fought him off, saving his mother’s life, but was wounded by a laserblast to his arm.

(Legion of Super-Heroes III #11) - The entire Legion of Super-Heroes held a quorum to deal with Legion business that’d been kicked down the road for months. Lightning Lad and Saturn Girl rejoined the team, and after the meeting they met with Cosmic Boy to reflect on their past. Cosmic Boy said they provided a sense of continuity since they were the original Legionnaires, and they all started to feel a little bit old.

(Legion of Super-Heroes III #14) - The Legion interviewed applicants during their membership drive and had them demonstrate their powers. The Legion Academy all tried out, with Bouncing Boy on hand to cheer them on. Mentalla applied for membership, saying she’d be a valuable addition because her powers were similar to Saturn Girl, although her telepathy was used to control minds instead of reading them. Comet Queen, Magnetic Kid and Tellus all made it to the second round, and were given a trial by fire, joining the Legion on a mission to find out why the bridges and drainage systems of the California Coastal District were breaking down. Brainiac 5 led the mission, and had Mon-El team up with Magnetic Kid to use their powers to raise the newly sunken sections of California. Comet Queen rescued civilians in danger of drowning and Tellus picked up the thought-patterns of someone with sabotage on their mind. At Legion hq Energy Boy demonstrated he ability to create nuclo-globes when Polar Boy interrupted him by freezing his nuclo-globe and hands to show the Legion that he’d gotten much better at controlling his powers. He told the Legion he’d dissolved the Subs, and asked that they waive their old rule that new applicants had to be under 18 to consider him. Tellus led his teammates to the northern cost, where he sensed the thought-patterns coming from. The coast buckled and Mon-El went to investigate, finding Dev-Em on the scene. Dev-Em was now working for the U.P.’s Counter-Intelligence Corps and was also investigating the damage being done to California. Dev-Em made it very clear he was not impressed with the new would-be Legionnaires, and said the Legion would be better off if they offered him membership again. Dev-Em said the Corps had learned that the Dark Circle left behind a few stragglers on Earth to commit acts of sabotage, and Tellus tracked down the saboteur, an Ontiir clone. The clone sat in a weapon-chair and was set off another destructive device that caused a tidal wave. Mon-El used his heat vision to evaporate the tidal wave while his teammates tried to pierce the clone’s forcefield. Quislet, an adventurer from a microscopic dimension flying in a miniatures Trans-D Vessel, joined the fray in an attempt to impress the Legion. Quislet could animate inanimate matter, and took control of the clone’s weapon-chair, using it to defeat him. Quislet returned to his Vessel, and the weapon-chair crumbled to dust, as was usually the case for any matter Quislet possessed. The Legion inducted Magnetic Kid, Polar Boy, Quislet and Tellus as new members. Saturn Girl said she had a recruit with an excellent reason to join the team, Sensor Girl. She wouldn’t reveal anything about Sensor Girl, but asked the Legion to trust her, much like they trusted her telepathy when she recommended Element Lad as a member, and the Legion welcomed Sensor Girl to their ranks.

(Legion of Super-Heroes III #15) - Wildfire took the new Legion recruits on a training course aboard a Legion cruiser, but a solar flare hit their vessel. Wildfire’s containment suit was destroyed, and he had to return to a Legion storage tesseract to get a new suit, grumbling that Brainiac 5 was unable to mass produce suits that gave him consistent powers. The beacon that lured spacefaring dragons away from Imsk while migrating malfunctioned, and Colossal Boy, Sun Boy, Shrinking Violet, Shadow Lass and Mon-El went to deal with the situation. Sun Boy used his solar powers to keep the dragons away from Imsk until the beacon was repaired. Element Lad contacted them via holo-screen and told them the new recruits were missing, and sent them to investigate. He assembled Blok, Dawnstar, Lightning Lass, White Witch and Ultra Boy to act as backup if needed. Dream Girl questioned his leadership abilities, asking why he was spreading the Legion so thin without going on the mission himself, and Star Boy told him to ignore her.  The Legion went to the quadrant where the rookies were last seen and came across a star that shot solar flares at them, dragging them to a nearby asteroid. The Legion realized that a beam from the asteroid was guiding the solar flares. Dr. Regulus was behind the attacks and revealed his captives. He was being aided by the burning ones, flame creatures that lived on the asteroid, and promised to free his hostages if Sun Boy fought him in one-on-one combat. Regulus’ quest for vengeance had driven him near madness, and he still blamed Sun Boy for costing him his job. The Legionnaires left Sun Boy to his confrontation with his nemesis, and although Regulus had the upper hand with the Burning Ones at his side Sun Boy slipped his Legion flight ring on Regulus, causing him to fly upward and knock himself out against a cavern wall.
