  * Jonathan and Martha Kent discover that their young foster son Tim Tates (Mighto of the planet Ulgar) has been using his super-powers to commit crimes. After tracking him down, they discover he possesses adult intelligence, and the super-powered child uses super-hypnotism to cause them to completely forget his existence. Leaving Earth on a mission for his true parents, Mighto soon meets a radiation-creature on another planet that gives him amnesia, causing him to forget who he is for several years until he becomes a teenager.

===March, 1950===
  * On Krypton, Jor-El discovers the Phantom Zone and proposes it successfully as a method of "execution" for Kryptonian criminals, replacing the previous method of putting criminals in suspended animation and sending them in a capsule into orbit. Thanks to his latest contribution, Jor-El is elected as a member of Krypton's ruling Science Council. (Kryptonian date: 3 Ullhah, 9999)
  * March 22: Under the direction of the goddesses Athena and Aphrodite, Queen Hippolyta of the Amazons forms two figures of raw clay in the form of baby girls, one made from light clay, and one made from dark clay. Aphrodite, knowing Hippolyta's dearest wish is to be a mother, brings the two clay statues to life. After the goddesses leave, Mars the god of war appears and takes away one of Hippolyta's infant daughters despite her pleas to stop. Later, the gods and goddesses Aphrodite, Athena, Hercules, and Mercury arrive to bestow the remaining child with beauty, wisdom, strength, and swiftness, naming her Diana after the goddess of the moon and mistress of the hunt. Princess Diana is raised on Paradise Island to enjoy the heritage of the Amazons. Meanwhile, Mars calls Hippolyta's dark-skinned daughter Nubia and raises her as his own daughter on an island off the coast of Africa named the Floating Island, called Slaughter Island by the Amazons, and also known as Mars Isle or Marzal. //Note: Despite hints that Diana may be hundreds if not thousands of years old, there is more evidence that indicates she is still a young woman when she becomes Wonder Woman and goes to live in Man's World. There are hints that Aphrodite and Athena are motivated to create Wonder Woman after seeing how powerful the god of war has become after two World Wars; Wonder Woman is their effort to provide a counterbalance to warlike mankind.// ["The Golden Age Secret Origin of Wonder Woman," Wonder Woman #159 (January, 1966); "The Secret Origin of Wonder Woman," DC Special Series #19 (Fall, 1979); "The Second Life of the Original Wonder Woman," Wonder Woman #204 (January-February, 1973); "War of the Wonder Women," Wonder Woman #206 (June-July, 1973)]

Ak-Var is sentenced to 19.5 Kryptonian years (equivalent to 26.9 Earth years) in the Phantom Zone. //Note: The story claims that Ak-Var is given a 30-year sentence, but neither 30 Earth years nor 30 Kryptonian years is possible, since the Phantom Zone wasn't discovered until after Kal-El's birth. Many years later, long after he is finally released after his sentence is completed, Ak-Var becomes Flamebird II, partner of Nightwing II (Van-Zee).// ["The Man from the Phantom Zone," Action Comics #336 (April, 1966)]

  * Adam Blake, now 20 years old and in his senior year at university in Midwest City, displays telekinetic abilities to move objects with his mind. Seeking help to know more about himself, he approaches Prof. Emery Zackro, a physicist who surmises that Adam is a mutant born 100,000 years ahead of his time. Following Zackro's advice, Adam Blake invents the costumed identity of Captain Comet so that evil men will not seek to exploit his powers as Adam. Meanwhile, a mysterious gigantic spinning top appears in the U.S. Southwest, but it proves impervious to harm, even after an atomic bomb is dropped on it. Six more tops appear around the world, all sucking up the atmosphere. Captain Comet discovers that the tops are controlled from space. He invents and constructs a spaceship of his own design called the Cometeer (which uses a faster-than-light spectrum drive) and heads to the dark side of the Moon, where he discovers a giant alien ship and learns that the Astur race seeks to take Earth's air in order to make the planet habitable for their population, which has been traveling in suspended animation for 1000 years. Captain Comet discovers that all but one of the Astur race has died. After that last survivor commits suicide, the ship moves away from Earth, and the tops cease to be functional. //Note: A Superbaby story in New Adventures of Superboy #24 indicates that Captain Comet preceded Superboy's career by a few years, which means that Captain Comet is officially Earth-1's first super-hero. Shortly after this story, Adam Blake graduates from university and gains a job as a library information clerk at Midwest City Library.// ["The Origin of Captain Comet," Strange Adventures #9 (June, 1951); "The Air Bandits from Space," Strange Adventures #10 (July, 1951).]

In its first mission, the Suicide Squad stops the mysterious threat of the three waves of doom, a flaming mass containing an unknown, monstrous, dragon-like menace that adapts against every force used against it. The only way the Suicide Squad is able to defeat the monster is to use a secret unmanned (but well-stocked) rocket to lure it into space, where they finally eject it near the Sun, leaving the team stranded in space for a few months. The Suicide Squad operates for nearly 24 years off and on before being finally disbanded by the U.S. government in 1983. //Note: This story takes place in winter several months before the published date.// ["The Three Waves of Doom," The Brave and the Bold #25 (August-September, 1959).]

Landing in a lake in an unknown country, the Suicide Squad discovers a plan by an enemy nation (most likely the Soviet Union) to attack the United States using atomic-warhead-equipped submarines; the team, still at small size, sabotages the entire fleet before returning to normal size and escaping to America.

  * Patrick "Eel" O'Brian, a petty criminal, becomes the heroic Plastic Man. //Note: This is the Earth-1 version of the Earth-2 character of the same name, whose adventures are virtually identical, except that they occur 18 years later. The last issue of Plastic Man (#52) featuring a new story with Plastic Man takes place in 1972, according to Earth-1's compressed timeline, since 1972 corresponds to 1954; therefore, if Plastic Man's adventures occurred over the same time span of 13 years on Earth-1, his debut year of 1941 corresponds to 1959. Accordingly, the other golden age heroes of Earth-1 -- the Vigilante, Air Wave, the Manhunter, the Guardian and the Newsboy Legion, Robotman, TNT and Dan the Dyna-Mite -- are similarly adjusted. It is fitting that Earth-1's golden agers debuted after Superboy and not before.// [Police Comics #1]

After Bruce convinces Harris to take him on as his protege, Harris gives the boy the nickname of Robin. Bruce spends much of this summer being trained by Harris while his guardian (Philip Wayne) is traveling abroad. //Note: This story claims that Bruce was a teenager when he met Harvey Harris and became the original Robin, and that his parents were still alive at the time, but this is incorrect. The Untold Legend of Batman #1 clarifies that Bruce instead met Harris nearly a year after his parents' deaths.// ["When Batman was Robin," Detective Comics #226 (December, 1955)]

She is soon visited by William Harrison, the corrupt attorney for Willowbrook Orphanage, who convinces her that she must return Donna to county care, or she will be taken away from her if she's bankrupt. Fay reluctantly agrees after being promised that Donna will go to a good home with loving parents. Instead, Harrison sells Donna to a child trafficking ring he's been working with for years. Donna Stacey is placed with an abusive couple posing as her adoptive parents, using a supposedly empty and non-rented room in a tenement building in New York City to sell children to ensure it cannot be traced to their names; the room is provided to them for cash under the table by Sam Channing, who keeps it a secret from his wife, the building's landlady. Meanwhile, Fay Stacey returns to school and later marries a man named Hank Evans, with whom she starts a new family, but is too embarrassed to tell him how she was tricked into giving up her adoptive daughter. ["Who Is Donna Troy?" The New Teen Titans #38 (January, 1984)]
  * April 26: While watching scenes of Man's World on the Magic Sphere, 15-year-old Princess Diana sees that a two-year-old girl is about to be killed in a tenement fire in New York City, so she uses the Time and Space Transformer to briefly switch places in time with her future grown-up self from 1972. As Wonder Woman, she travels to the building in New York with her invisible robot plane and saves little Donna (Donna Hinckley Stacey) from the fire, although she's too late to save the lives of the man and woman with her, which she wrongly assumes to have been her parents. Discovering that the child's identity is untraceable, since the landlady Mrs. Channing says the room Donna was found in wasn't rented, Wonder Woman brings her back to Paradise Island before transforming back into a teenager. Since her past and true family are also clouded from being traced via the Magic Sphere, Donna is adopted as Queen Hippolyta's daughter and Princess Diana's sister and is raised as an Amazon, though she lacks their powers for most of her childhood. Some years later, Wonder Woman becomes Donna's legal guardian. //Note: The Time and Space Transformer is used in a similar way in "Wonder Tot and the Flying Saucer," Wonder Woman #132 (August, 1962) and was originally invented when Princess Diana was a teenager, as seen in "Wonder Girl Meets Wonder Woman," Wonder Woman #117 (October, 1960). Donna cannot have been saved from a fire as a toddler during Wonder Woman's actual career, since Diana didn't become Wonder Woman until 1972, by which time Donna was already nine years old and living on Paradise Island; thus, the only way Wonder Woman could have rescued a two-year-old Donna is through some kind of time travel. The Magic Sphere should have theoretically traced Donna's earlier life, but since it apparently never did so, we speculate that it was somehow clouded from view, possibly by the gods who knew Donna would one day become Wonder Girl. Wonder Woman probably didn't apply to be Donna's legal guardian until sometime after her debut in 1972.// ["The Origin of Wonder Girl," Teen Titans #22 (July-August, 1969); "School of the Amazoids," Adventure Comics #461 (January-February, 1979); "Who Is Donna Troy?"

  * The Blackhawks fail the test of a secret agency named G.E.O.R.G.E. in front of four super-heroes and the U.S. President, therefore they retire and then begin the "New Blackhawk Era", donning super-hero names, powers and costumes as members of G.E.O.R.G.E. Blackhawk gains the code-name "the Big Eye", Chuck becomes the Listener, Hendrickson the Weapons Master, Olaf the Leaper, Stanislaus the Golden Centurion, Andre becomes M'sieu Machine, and Chop-Chop becomes Dr. Hands. //Note: This story must take place in the 1960s following previous issues, since Lady Blackhawk is still hypnotized and acting as Queen Killer Shark. The uncharacteristic New Era Blackhawks may not have been the real Blackhawks after all, but instead doubles (perhaps shape-changing Martians) who replaced the originals in an untold story, partially in order to drive the real Blackhawks into retirement. The presence of Superman, Batman, the Flash, and Green Lantern in this story is problematic but must be accounted for. It's possible that the roles these four play in the compressed Earth-1 timeline were held by four contemporary and prominent 1960s super-heroes such as Superboy, the Vigilante, Plastic Man, and Air Wave. It is also possible that the four JLAers were sent back through time magically by Felix Faust during the events of Justice League of America #49, which takes place in September, 1977; in this case, Superman would have been able to prove his identity to President Johnson and vouch for his three fellow super-heroes, then unknown to the world, since he was personally acquainted with the U.S. presidents ever since he first became Superboy. Presumably the magical transportation would not have displaced Superboy or the then-teenage Batman, Flash, and Green Lantern (Bruce Wayne, Barry Allen, and Hal Jordan) like ordinary time-travel does.// [Blackhawk #228-230]

Later, Jonathan Kent uses Superboy's memory helmet to erase his memories of these events, and Superboy/Superman forgets for the next 21 years. //Note: This story is set specifically 15 years after Krypton's destruction, placing it out of sequence with other stories in this series.// ["Superboy's Darkest Secret," Superboy #158 (July, 1969); "[[https://5earths.com/earth-1/superman-e1-1988-03-01/|Superman: The Unkindest Cut]]"]

Before he can bring it to a museum to be translated, Battles is ambushed by bandits. Escaping from them, Battles uses Zantec's golden belt to split himself into two. One of his bodies acts as a decoy to draw the bandits away while the other takes the tablet to the museum. Unfortunately, the decoy is captured by the bandit leader El Grando, and the one with the tablet is ambushed outside the museum by bandits who steal the tablet. El Grando has the tablet translated and leaves to dig up the relics, while one Battles saves his other body. Reaching the dig site in a helicopter, the two Battles spot El Grando wearing the legendary head-band, which gives him the ability to emit blasts from his eyes. Battles' two bodies team up to defeat El Grando and destroy the head-band, rejoining just in time before sundown. //Note: Despite the title of this story, Cliff Battles is never actually referred to as Split Man. // ["The Split Man," Strange Adventures #203 (August, 1967)]

After this story, the Robot-Teacher rewrites Misty's mind to its previous state and returns her to her real life. //Note: Although this story was published before The New Adventures of Superboy series, the context places it after that series in Clark Kent's graduating year, when he is on the verge of manhood, making this an untold tale similar to the one seen in Superman #146, which shows how the Kents die.// ["Don't Call Me Superboy," DC Super Stars #12 (February, 1977)]
