Synopsis for Supergirl: "The Unknown Supergirl"
This story is reprinted from Action Comics #278.
After repairing the damage an overnight windstorm did to the Midvale Orphanage carnival, Supergirl gets a visit from Krypto, that gives her a note telling her to come see Superman. Kara follows Krypto all the way back to a tiny isle where she finds out that her cousin's decided it's time that the public learns of her existence. After showing her several videos of her exploits, he tells he plans on making the reveal once he and Krypto return from a mission in another dimension, leaving Earth in Supergirl's protection.
Kal-El and Krypto depart, leaving Kara to her own devices. Supergirl is whiling away on the isle when her telescopic vision detects a cloud of Kryptonite dust ringing itself all over the Earth. Seeking protection from it, Supergirl dives into the ocean and is helped by Jerro, who pulls her further down where she'll be out of range from the K-radiation. Both teenagers seek refuge in Atlantis where they are reunited with Lori Lemaris.
While Kara and Lori recall old times, tv newscasts report the existence of the Kryptonite cloud, remarking Superman may have died unless he found a lead-lined shelter or flew into space in time. Law-abidding citizens are frightened, but criminals rejoice.
Undersea, Jerro is showing Supergirl around Atlantis when Lori warns them criminals all over the world, believing Superman is gone one or another way, have launched a great crime spree. Supergirl, watching from afar with her x-ray vision, uses her super powers to stop all the crimes on land without leaving the ocean. Ironically, people believes it is Superman who is helping them out.
After a number of successes, the Kryptonite cloud dissipates and Supergirl can return to Earth. She flies back to the island right before Superman and Krypto return from their mission. Superman leads her cousin to a tv station where he plans to make the announcement when Supergirl's powers suddenly disappear.
Superman flies her cousin to the Fortress of Solitude where he runs several tests. He can't figure out the reason, but Kara appears to have lost her powers permanently. Without any super-powers, Superman decides against revealing her to the public for her own safety. Kal takes his devastated cousin back to the Midvale Orphanage. Before leaving, he swears to do all he can to restore her powers.
Although her cousin tries to cheer her up, Kara fears their relationship will be different from now on. Kara changes to her Linda Lee identity and goes back to her bedroom. Before falling asleep, Kara tries to see the silver lining: now she is no longer Superman's secret weapon, she has no reason to avoid adoption. But what caused her power loss?

Synopsis for Supergirl: "Supergirl's Secret Enemy"
This story is reprinted from Action Comics #279.
Supergirl lies in her room in the Midvale Orphanage, feeling sorry because she has lost her powers right when Superman was about to reveal her existence to the world and freeing her from operating clandestinely.
Unbeknownst to Supergirl, she had been monitored by a Kandorian scienstist called Lesla-Lar. Envious of the acclaim and praise humans were sure to give Supergirl, Lesla had grown to hate her. Before Superman went about revealing his cousin's existence to the world, Lesla used one of her machines to nullify Supergirl's powers out of despite. Lesla congratulated herself for her success, but she wasn't over with scheming against Supergirl yet.
Back on the Orphanage, Linda brushes her tears away and forces herself to forget the past and put a brave face. Shortly after Linda is finally adopted by a marriage. Her orphan friends throw a going-away party, and Linda moves with Fred and Edna Danvers, taking her pet cat Streaky with her. Her new parents are happy to have her, but Fred suspects she's hiding some past grief when she winced after being said she looks "super". Silently, Fred wonders if she'll open up to them some day.
That night, Linda is visited by her cousin Superman. Linda, who thought Kal-El had forgotten her for now, hugs him, sobbing. Faster than sound, Superman builds her a special room to hide her Supergirl costume, even though she has no powers to use. Linda tries and fails to keep smiling, and wonders if her powers will return someday. Streaky, who no longer has his piece of X-Kryptonite readily available, is as well making himself that question.
Linda falls asleep shortly after. While sleeping, Linda is shrunk and teleported to Kandor by Lesla-Lar, who uses her devices to brainwashing Linda into believing herself to be Lesla-Lar. Lesla exchanges clothes with Linda, grabs a teleport bracelet which will allow her to swap places with Linda whenever she desires, and then takes Linda's place on Earth.
While a mentally-conditioned Linda covers for the real Lesla-Lar's absence, Lesla poses as Linda on Earth. First she uses her X-Ray vision to spy on Fred Danvers working on rocket experiments. Later that night she dons Linda's Supergirl's costume and visits Lex Luthor in his cell. Lesla claims to be a supergirl from another planet who wishes being his secret emergency weapon out of admiration for him, and springs Luthor from jail, leaving a dummy in his place to cover for him.
The two criminals team up to steal an armored car before Lesla returns Luthor back to his cell to avoid detection. However, the real Linda had accidentally monitored their activities and tries to warn the people of Kandor about an evil supergirl out here. The real Lesla's super-senses pick up on Linda's actions and she uses her fail-safe to return Supergirl back to Earth and into her bed, and switch places back. Supergirl wakes up screaming, and dismisses the whole episode as a nightmare.
Meanwhile, Lesla-Lar is ready to set her plan's next phase in motion.

Synopsis for Supergirl: "Trapped in Kandor"
This story is reprinted from Action Comics #280.
Linda Danvers begins her daily routine, and being almost late for class, she begins to realize she took her lost super-powers for granted. That day, her class goes on a field trip to the Daily Planet in Metropolis. There Clark Kent tells Linda that he's going to make one final attempt to come up with a way to restore her powers. Watching this from her monitor in Kandor, Lesla-Lar comes up with an idea to trick Superman to further her own criminal goals.
That night, Lesla-Lar uses her devices to swap places with Linda Lee as she sleeps, so that she can operate on Earth under the guise of Linda Lee/Supergirl, while the real Supergirl is mentally conditioned to think she is Lesla-Lar. She meets up with her partner, Lex Luthor in his prison cell and tell him that she wants him to build a Green Kryptonite ray to destroy Superman, seeing how to do so herself would kill her. They plot to assassinate Superman but Lesla wants Luthor to design the machine and get full credit so that the world figures Supergirl is on the side of the law when she reveals herself to the world, while in reality Lesla-Lar is working with Luthor.
While in the city of Kandor, "Lesla-Lar" goes about her daily tasks and becomes interested in Supergirl's exploits. She begins watching video presentations of Supergirl completely unaware that she is watching her own history. Meanwhile, the real Lesla-Lar, still posing as Linda Lee meets with Superman. Superman tells "Linda" that he cannot restore her powers, however Lesla-Lar tricks Superman into thinking she found an instant cure and restored her powers from breathing the vapors of a melted rock. Using her x-ray vision "Linda" spots a canyon that is being effected by an earthquake. Superman rushes to the rescue, and "Supergirl" secretly reshapes the rocks Superman is knocking aside into a unique stone formation across a road.
Later while congratulating her for her help, Superman reveals to "Supergirl" that he is convinced her powers have returned in full and she has not lost any skill and decides that they should reveal her to the public right away.
Lesla happily ponders her plot is working out just as planned: once Luthor murders Superman, she'll "accidentally" kill Luthor while capturing him. Then she'll be free to conquer or destroy Earth if she wishes while the real Supergirl spends the rest of her life in Kandor.

Synopsis for Supergirl: "The Three Red K Perils"
This story is reprinted from Action Comics #283.
Kara Zor-El/Linda Danvers has recovered her Kryptonian powers and gained immunity to Kryptonite thanks to Mister Mxyzptlk's meddling and she's happier than she's been in a long while. As she does her chores, though, she can't help but think how dull they are and how easier it would be if she revealed to her parents her secret.
At afternoon, Linda goes skating with Dick Malverne. Dick asks her to go out the next day and Linda replies she would love to, but she isn't sure she can get away. When both her parents and Kal-El leave, though, she finds herself bored and streaks into space. Kara spots a swarm of six Red Kryptonite meteors and promptly smashes them to atoms. Afterwards, she decides to fly back Earth, go to the Midvale's fair and join Dick.
Supergirl changes back into Linda Danvers and goes to the fair, but all of sudden she turns into a fat woman. Linda realizes she may be immune to Green-K, but she's still affected by Red-K. Linda manages to get away unseen and turns back to normal, but she remembers there were six meteors. Worried, she wonders how she'll be affected by the five remainder pieces of Red Kryptonite.
At evening, Linda and Dick go to the movies. Sitting near from them Linda spots Rolf Von Holtz, a famous movie director, arguing with Conway Tremaine, a great horror film writer. Linda feels sorry when she overheards the latter asking the former for a last chance and being denied. All of sudden she feels she's transforming again, this time into a werewolf. Linda snucks out quickly and gets her Linda Danvers Robot pose as Dick's date. In the meantime she sees Tremaine is about to commit suicide and pulls a quick appear-scare-and-disappear act, successfully inspiring him to write another movie.
Thankfully, the Red-K effect wears off. Linda switches places with her robot and Dick takes her back home. Linda still wonders whether he's made it back home safe and decides to check in on Dick using her super-senses. Linda finds out Dick's father has contracted a rare disease and may never wake up again unless a new experimental serum works.
Linda wonders what she can do to help when she's turned into a microbe-sized girl. Glad to be able to help now, Kara flies towards the Midvale Hospital and into Mr. Malverne's room, and enters his blood stream. Supergirl fights off millions of disease bacteria in Dick's foster father's bloodstream until Mr. Malverne has stabilized, and feeling the Red-K effect starts wearing off, she goes out, letting the white blood cells do their job.
Supergirl succeeds in helping save Mr. Malverne. She's happy, but she wonders how the last three Red-K meteors will affect her.

Synopsis for Supergirl: "The Super-Mermaid"
This story is reprinted from Action Comics #284.
Wanting to forget her troubles, Linda visits Midvale's fair. As she's combing her hair in a restroom, Linda grows another head due to the Red-K effect. "Supergirl Head No.2" -as dubbed by Linda- is completely confused and argues with Linda, wanting to look at the fair even though Linda wants to get away unseen. Fortunately for Linda, everybody thinks she's one of the workers of the freakshow, and the second head vanishes after Linda catches and detonates safely a bomb accidentally dropped off by a jet.
Supergirl flies back home at the same time her parents come back from an emergency trip to Europe. Soon after Supergirl gains the uncontrollable ability to slay anything living she gazes upon, including her parents and Krypto. Desperate, she streaks into space and comes up with a way to put their fatal vision to good use: wiping out one race of globular monsters which travel through the space to prey on other alien lifeforms. Once she's through with them, Kara collapses on her knees, sobbing.
Suddenly Supergirl finds herself back in her home, in her Linda identity, and looking at her, clearly still living, parents. She guesses she's just experienced a Red-K induced hallucination.
Later, Kara is blowing rainclouds over a farm area when the final Red-K effect changes her into a mermaid. Since she looks like a fin-tailed Atlantean, Kara decides to pay a visit to Jerro and Lori Lemaris. Kara is introduced to Lenora, Lori's sister who has a crush on Jerro. When Jerro proposes to Supergirl, Lenora runs away, broken-hearted. Oblivious due to her grief, Lenora blunders her way into the "Valley of Hands." Jerro explains that Atlantis was invaded several centuries ago by an alien race of giants. The Atlantean weapons were useless, but the giants sank into the valley's bogs and only their upraised hands remain in view. Supergirl swiftly streaks into the Valley and pries Lenora from a giant hand.
After swimming Lenora to safety, Kara senses her body changing back to normal. Supergirl says goodbye to Jerro and Lenora and flies out of the ocean. Unexpectedly, she feels pangs of pain when a Green Kryptonite meteor flies past her. Supergirl is wondering why she's lost her immunity to Green-K when Superman turns up. While returning from the future, her cousin overshot his mark and arrived a few days in the past. He saw Mister Mxyzptlk giving her super-powers magically. Evidently his magic wore off and Kara's original powers have returned.
But that's in the past. Now Supergirl's powers have finally stabilised, Superman intends to reveal his cousin's existence to the world.

Synopsis for Supergirl: "The World's Mightiest Heroine"
This story is reprinted from Action Comics #285.
Superman declares it's time to reveal his cousin Supergirl's existence to the world, much to the latter's immense delight. First they have to disclose the truth to Linda's adoptive parents, though. Kal-El says he'll meet her at 9:00 and then they'll tell her parents together. Both cousins part company, and Kara flies back home and changes back into Linda Danvers.
With hours before 9:00, Linda agrees to go with the Danverses to see a movie in Metropolis. However, along the way the bridge they are crossing breaks under the weight of their car. Linda quickly springs out, catches the falling car and flies it to safety. Linda gets upset, thinking she's revealed herself before the appointed time. Her parents leave the car and ask an explanation, surprised, but she doesn't dare to tell them anything.
Right then Superman touches down and says it's all right and she can tell her parents everything. He finished his patrol early and was flying back to Midvale when he saw her rescuing her parents. Although Kara was worried he'd change his mind, Kal states she did the right thing and he's still going ahead with the reveal.
More confused than ever, the Danverses want to know what Superman and their daughter are talking about. Finally, Kal and Kara explain the latter's origins. The Danverses are proud of being Kara's parents and swear to protect her secret. The family goes back to the Danvers household where Supergirl builds a secret tunnel exit out of their house much like what Superman had when he was Superboy in Smallville. While watching his cousin and her adoptive parents hugging each other, Superman can't help missing the Kents.
The next morning, broadcasting from the Fortress of Solitude, Superman reveals Supergirl to the world. The revelation sends cheers all over Earth and the galaxy. After the celebrations are done, Superman heads off on a mission into the 50th Century leaving Supergirl to defend the Earth while he is gone.

Synopsis for Supergirl: "The Infinite Monster"
This story is reprinted from Action Comics #285.
Soon afterward, two scientists accidentally open a space warp, while trying to communicating with other worlds. A giant creature, so large all one can see are its legs tromping across the land, falls through the gap. The creature is named the Infinite Monster, and Supergirl is called to stop its rampage.
Supergirl soon discovers simple brute force will not stop the monster. After being literally stomped on, Kara comes up with an idea. Rapidly, she builds a crude missile, puts a note inside it, and throws it through the time barrier to the 30th Century. There it's intercepted by the Legion of Super-Heroes who read Supergirl's note and send her back Brainiac 5's shrinking ray. Unfortunately, the Infinite Monster steps on it. Supergirl repairs the device at super-speed and fires at the monster, who gets shrunk down to miniature size. Kara grabs the monster and flies towards the Fortress of Solitude to put it into a special cage, satisfied that she's proved her worth.
With her first public mission a success, Supergirl is once more celebrated by everyone including the President of the United States. When Superman returns to the present he congratulates Supergirl for a job well done and publicly thanks her. Then he shows he's built a new wing, just for her, in his Fortress. Supergirl heads back to Midvale, where she's warmly greeted by her parents, and wonders what her life will be like from now on.
