Synopsis for Legion of Super-Heroes: "The Secret of the Mystery Legionnaire!"

This story is reprinted from Adventure Comics #305.

With the recent demise of Lightning Lad, the Legion of Super-Heroes begins looking for an adequate replacement to fill the void left by the heroes death. After testing a series of would-be Legionnaires who's powers either turned out to be duds or artificial, the Legion is met by a costumed youngster calling himself Marvel Lad.

Wanting nothing but the best possible candidate to take the late Lightning Lad's place, the Legion puts Marvel Lad on a series of complex tests to see if he stands up to the Legion's values and codes. When Marvel Lad is able to complete all the missions the Legion asks him to reveal the origins of his powers before he is introduced into the group.

The next day Marvel Lad arrives and reveals that he is really Mon-El in disguise. He then reveals to an astonished Legion that Brainiac 5 had developed a new version of serum XY-4 to try and cure Mon-El of his lead poisoning that forced him to reside in the Phantom Zone. To test out if the serum will work, but not get the other Legion's hopes up, Mon-El took on the guise of Marvel Lad and try out for Legion membership, that way if the serum didn't work the Legion wouldn't be disappointed.

Having passed the Legion's tests, Mon-El is welcomed into the Legion as their new member, and Mon-El returns to the Phantom Zone one last time to get the last laugh on the criminals trapped there who have taunted and tormented him during his time living within the Zone.

Synopsis for Legon of Super-Heroes: "The Legion of Super-Monsters!"

This story is reprinted from Adventure Comics #309.

With the other Legion members out on various mission, Saturn Girl, Chameleon Boy, Colossal Boy, Bouncing Boy, Brainiac 5, and Sun-Boy are tasked with selecting a new member into their group. When an applicant named Jungle King, who can control animals with his mind, tries to join the group he is rejected for membership as the animals he control can be easily startled and become a menace.

Angry that he had been rejected, Jungle King uses his powers to gather some of the most dangerous creatures in the universe and forms "The Legion of Super-Monsters" and renaming himself Monster Master for the purpose of terrorizing people and getting revenge against the Legion. His first attempt at revenge, toppling Sky City, is met with failure when the Legion arrives and stops the city from being toppled over, however Monster Master and his Super-Beasts manage to escape.

Tracking Monster Master to the planet Inshar, the Legion draw straws to have one of them run recon on the Super-Monsters, and are not confident when Bouncing Boy wins. Despite their lack of faith, Chuck actually defeats the most powerful of the Super Monsters by tricking it into burying itself. The rest of the group is little trouble. Ironically, Monster Master meets his own demise when he rejects a vapor-beast interested in joining his Legion of Super-Monsters. The rejected beast then touches Monster Master, killing him as when such a creature touches it's prey it becomes a lifeless vapor. With the menace of the Monster Master ended, the Legion marvel over the irony of their foe's defeat.

Synopsis for Jimmy Olsen & Legion of Super-Heroes: "The World of Doomed Olsens!"

This story is reprinted from Superman's Pal, Jimmy Olsen #72.

Jimmy is taking part in a televised showcase of has many adventures, focusing particularly on the formula that turns him into Elastic Lad, and his various other transformations over the years. His special is suddenly interrupted by an alien creature calling itself the Collector who kidnaps Jimmy with it's scientific devices.

Jimmy finds himself transported to an alien world where the Collector hopes to make a collection of all the various incarnations of Jimmy Olsen. Rooting Jimmy to the group (by literally turning his feet into tree roots) the Collector keeps Superman at bay as well and apparently brings forth the giant monster Jimmy, the wolfman Jimmy, porcupine Jimmy and fat Jimmy before the real Jimmy. These alternate versions of him terrorize him before they themselves are rooted into the ground.

Before the Collector can do anything else Jimmy suddenly pulls the microphone that's been attached to him since the TV interview, and throws it at the Collector scaring the creature, thus proving to Jimmy that it's a ruse. Jimmy had deduced that the "Collector" is really Mon-El in disguise (due to his reaction to the microphone which was made with some lead parts which used to be a weakness for Mon-El) and that the other "Jimmy's" are really other members of the Legion of Super-Heroes (who are revealed to be Colossal Boy, Chameleon Boy and his new pet Proty II, Cosmic Boy, and Bouncing Boy.)
Jimmy learns that this was all planned by the Legion and Superman as an initiation for Jimmy, who is taken to the 30th Century where he is awarded an honorary membership in the Legion of Super-Heroes.

When most the female members of the Legion of Super-Heroes (and Night Girl of the Legion of Substitute Heroes) come down with the Crimson Virus, they have to be sent to a quarantine planet. The rest of the female members are hunted down by a mysterious masked villain named Satan Girl, who seems to be infecting the female Legionnaires with the virus.

With the arrival of Supergirl, who is immune to the virus, the male Legion members try to learn the origins of Satan Girl. When she proves immune to Kryptonite, Lead and an anti-android weapon, the heroes are puzzled to figure out her true identity. Unable to defeat her due to her superior powers, Supergirl has the Legion go and collect the Legion of Super-Pets, as Satan Girl's powers would not effect them. The Super-Pets manage to easily defeat Satan Girl, who is unmasked, revealing that she is really -- Supergirl!? The weakened Satan Girl explains that she is the product of Red Kryptonite, which Supergirl was exposed to upon entering the 30th Century. Knowing that she had only 48 hours of life, she adopted the guise of Satan Girl and created a device that would siphon the Red Kryptonite radiation and infect females with it, in hopes that once she had rid herself of the Red Kryptonite energies she could live past the 48 hour period which Red Kryptonite effects.

With her plan a failure, and the 48 hours running their course, Satan Girl merges with Supergirl. After wards, the Legion learns that Satan Girl managed to handle Green Kryptonite because she wore a lead suit. After this revelation, although they are victorious and their female members restored to normal, the Legion takes a moment to feel pity for Satan Girl, for all she wanted to do was live.
