The Exaggerated Death of Ultra Boy

In the 30th century, newly elected Earth President Marte Ida Allon (the mother of Colossal Boy) demands that the Legion of Super-Heroes disband, since the Legion's by-laws prohibit Legionnaires from killing, and Brainiac 5 apparently murdered Rimbor native An Ryd during a period of mental instability.[1] To avoid dragging the team into a political quagmire, Brainiac 5 resigns. Convinced that his teammate was framed for An's murder, Chameleon Boy travels to Rimbor to investigate, along with Star Boy, Phantom Girl and Ultra Boy. They gather enough evidence to clear Brainiac 5, but are attacked by Pulsar Stargrave, the stellar energy wielding android who is actually Superman's 20th century foe, the original Brainiac.[2] Stargrave strikes Ultra Boy with a nova blast, seemingly disintegrating him. Brainiac 5 journeys to Rimbor's moon where he defeats Stargrave, who once masqueraded as his father.[3]

Believing Ultra Boy to be dead, the Legionnaires hold a memorial service, and erect a statue of him in the Hall of Heroes. In reality, the unconscious Ultra Boy travels light-years through space until he is retrieved by the pirate ship Antares. He regains consciousness with no memory of his identity. The pirates' leader, Captain Frake, adds him to her crew when she sees him using his powers. Soon thereafter, the Legion answers a Science Police distress call and attacks the pirates in orbit over Pluto. Despite the Legion Cruiser's superior power, the Antares is able to escape, largely because the amnesiac Ultra Boy is on her side. Frake attempts to seduce him, but his hazy memories of his romance with Phantom Girl prevent her from succeeding. Gradually, the Legionnaire's natural heroic instincts reassert themselves, such that he turns against the pirates when the Legion locates the Antares again and the ship is destroyed. Frake tries to destroy the Legion Cruiser using a massive radiation weapon, energized by a quintile power crystal. Ultra Boy jumps in front of the blast, which ricochets into the power crystal—leading to a massive explosion which destroys both the pirates and their lair. Ultra Boy disappears. Saturn Girl, who had earlier sensed his thoughts after his supposed death, begins to think that her mind is playing tricks on her.

While helping to rescue a sinking cargo-craft in the Pacific Ocean, Phantom Girl's leg becomes entangled in a huge strand of seaweed and she almost drowns. She is saved by a powerful metahuman named Reflecto, who flies her back to Legion Headquarters. Shortly thereafter, Grimbor the Chainsman erects a network of chain-like energy beams around the Earth. With spacecraft unable to bypass the chains, Grimbor demands that the United Earth Council surrender the Legion to him within twenty-four hours. In space, the Legionnaires are unable to destroy the energy chains, but Saturn Girl manages to track Grimbor to his stronghold near the North Pole.

Reflecto follows a group of Legionnaires containing Phantom Girl, displaying genuine concern for her well-being. He utilizes super-strength, invulnerability, super-speed and vision powers, making him seem familiar to Bouncing Boy and Duo Damsel. Later, as the energy-chains contract and begin to compress Earth's atmosphere, the Legionnaires attack Grimbor's stronghold. Having prepared in advance, Grimbor manages to defeat each Legionnaire, blaming them for the death of his lover Charma, who was killed by her fellow prison inmates.[4] Using the Augmatron, a device she has secretly built, Princess Projectra determines that the main Earth Council satellite is the key to the energy field. Karate Kid destroys the satellite, thereby dissipating the chains. Meanwhile, Grimbor concludes that Reflecto is actually Ultra Boy in disguise. While Reflecto is using his super-strength, Grimbor blasts him with a powerful energy weapon. Reflecto survives the blast using his invulnerability. With the hero using two superpowers at the same time, Grimbor realizes that he could not be Ultra Boy.[5] Reflecto knocks Grimbor unconscious, and then collapses himself. As her teammates arrive, Phantom Girl discovers that Reflecto is wearing a mask, along with a second costume beneath his uniform. The Legionnaires are shocked to learn that Reflecto is actually their 20th century teammate, Superboy.

Superboy awakens, with Ultra Boy's conscious memories and personality overriding his own subconscious memories. Baffled by the Boy of Steel's appearance in the 30th century, particularly in light of Saturn Girl's hypno-pathic command that he remain in his own era,[6] team leader Lightning Lad takes six Legionnaires with him to 20th century Smallville: Phantom Girl, Karate Kid, Dawnstar, Saturn Girl, Blok and Superboy himself.[7] Their Time Bubble materializes as a nuclear bomb is detonating. Superboy funnels the radiation harmlessly into space, but is unexpectedly attacked by the U.S. Army, who claims that he stole and detonated the bomb. The Legionnaires flee, seeking sanctuary at the Kent home. The group decides to briefly return to the 30th century, but the Time Bubble begins to shake violently and shatters. Suddenly, the Time Trapper reveals himself, stating that he is taking advantage of the Legionnaires' current dilemma to trap them all in the past.

With the Trapper's Iron Curtain of Time firmly in place, Superboy, Lightning Lad, Phantom Girl, Karate Kid and Saturn Girl venture into Smallville incognito. They are quickly recognized by Lana Lang, who is an honorary Legionnaire in her guise as Insect Queen.[8] To protect Superboy's secret identity, they refuse to answer most of her probing questions. Soon, a new Molecule Master android attacks the group,[9] who is joined by Blok and Dawnstar. After confirming that he was created by the Time Trapper, he battles the Legionnaires until he is overwhelmed and implodes. With the Army still viewing Superboy and the Legion as a threat, Phantom Girl shifts Superboy, Dawnstar and herself to her homeworld Bgztl, which lies in a parallel dimension at the same space-time coordinates as Earth. The other Legionnaires are captured by the military.

The implosion of the Molecule Master restores Superboy to normal. As Phantom Girl leads her teammates through trans-dimensional space back toward Earth, Dawnstar senses a familiar presence. Using her tracking powers, she manages to locate Ultra Boy—alive but immobilized by a strange aura. He explains that the explosion of the pirates' quintile power crystal propelled him backward in time, in a ghost-like state. Travelling back to 20th century Smallville, he tried to enlist Superboy's help, but unintentionally superimposed his memories over those of the Boy of Steel. He tried to use the A-bomb test to break free, but only succeeded in further scrambling their memories. Upon travelling back to his own century, Saturn Girl's hypno-pathic command over Superboy asserted itself, subconsciously forcing him to create the Reflecto identity.

Using nearby radioactive rock, Superboy frees Ultra Boy. Meanwhile, Lana uses her Bio-Ring to become Insect Queen and attempts to free the jailed Legionnaires. Just as the military is about to defeat her, Superboy's group arrives and frees their teammates. The heroes travel to Bgztl, from which Superboy and Ultra Boy are able to bypass the Trapper's Iron Curtain and return the group to their own era. They attack the Trapper in his Citadel and defeat him—for the time being.[10] Saturn Girl mentally erases Superboy's knowledge of the circumstances surrounding his parents' deaths,[6] and he returns to his time period, where he plans to explain things to the President of the United States and obtain a pardon. The Legion converts the Ultra Boy statue into a Reflecto statue, making Ultra Boy the only living Legionnaire enshrined in the team's hall of deceased heroes.[11] Thrilled to be reunited with each other, he and Phantom Girl go on leave for a few days.
