Brainiac is apparently destroyed by being shrunk out of existence by his own shrinking ray. Superman and Supergirl finally succeed in enlarging the Bottle City of Kandor on a distant planet selected by the Kandorian Science Council: a "phase world" orbiting a red sun that periodically shifts in and out of Earth-One's dimension. Zor-El and Alura invite Supergirl to stay with them, but she decides to return to Earth instead. NOTES: Adventure Comics #356 (May 1967) first established that Kandor was eventually enlarged on a planet called Rokyn, which became the primary home of the scattered survivors of Krypton. The Kandorians' new world is unnamed in Superman #338; it first acquired the name Rokyn in its next appearance in Krypton Chronicles #1 (Sept. 1981). Brainiac's fate in this story was first described by Brainiac 5 in Action Comics #276 (May 1961), who said it was the villain's final defeat. However, Brainiac subsequently returned in Action Comics #514 (Dec. 1980). Superman v.1 #338 (Aug. 1979)
Jon Ross, son of Superman's old friend Pete Ross, is kidnapped by the warlike Nyrvnian race. The Legion visits the 20th century to persuade Superman not to rescue Jon because he and the Nyrvnians are destined to one day help Earth repel an invasion from another galaxy. NOTES: This story is the first time Superman learns that Pete Ross knew Clark Kent was Superboy, a discovery that Pete made in Superboy #90 (July 1961). Jon Ross first appeared (and learned Superman's secret identity) in Action Comics #457 (Mar. 1976). DC Comics Presents #13 (Sept. 1979)

On a mission in deep space, Supergirl develops temporary amnesia after being knocked unconscious by a Kryptonite meteor. She subsequently falls in love with and marries Salkor, the super-powered hero of the planet Makkor, who dubs her "Jasma." Regaining her memory after a subsequent injury, Supergirl returns to Earth, having completely forgotten everything that transpired during her period of amnesia, including her brief marriage. She does not regain her memory of Salkor until more than a year later and never sees him again. NOTES: The chronological placement of these events is speculative. Salkor later tells Superman that he met Supergirl two years before her death, although whether that was terrestrial or Makkorian years is unclear. She's said to have regained her memory shortly after the conclusion of her fight with Blackstarr in Supergirl v.2 #15 (Jan. 1984). (Superman v.1 #415, Jan. 1986)
Supergirl battles Universo with some help from the Legion. Superman Family #207 (5-6.81)

The prisoners in the Phantom Zone mentally compel the amnesiac Quex-Ul (who believes himself to be an Earthman named "Charlie Kweeskill") into freeing them from the Zone. They trap Superman and Quex-Ul in the Zone and begin a rampage on Earth. Mon-El informs Superman and Quex-Ul of a way to escape from the Zone, which Superman eventually does, although Quex-Ul sacrifices his life to save Superman's. The escaped Kryptonian villains are returned to the Zone. NOTES: Quex-Ul first appeared in Superman #157 (Nov. 1962). Phantom Zone #1-4 (1-4.82)
The Legion is summoned to the 20th century by Jimmy Olsen to help Superman stop Mongul, who is attacking the solar system with a Sun-Eater. Wildfire destroys the Sun-Eater by releasing his anti-energy into its core. NOTES: Mongul first appeared in DC Comics Presents #27 (Nov. 1980) DC Comics Presents #43 (Mar. 1982)
Superman is forced to restore Brainiac's original, malevolent programming in hopes that the android will be able to find some way to stop a fiendish planet-eating machine world that Brainiac created years before.

He rededicates himself to the destruction of Superman and the enslavement of the universe. NOTES: Brainiac's transformation makes it unlikely that he eventually would have become Pulsar Stargrave, contrary to Stargrave's claim in Legion v.2 #273 (Mar. 1981). Action #544 (June 1983)
The irrepressible Ambush Bug hitches a ride with a time-traveling Superman and runs amok in the 30th century. NOTES: Ambush Bug first appeared in DC Comics Presents #52 (Dec. 1982). DC Comics Presents #59 (July 1983)

NOTES: A few months after these events, the pre-Crisis reality, including Superman's history as Superboy and the existence of Supergirl, disappears and is no longer remembered by residents of the DC universe. Crisis #12 (Mar. 1986)
  PRE-CRISIS ONLY:Htrae, the Bizarro World, collapses to become a white hole, killing all of the Bizarros and causing the Aethyr — the extra-dimensional collective consciousness which contains the Phantom Zone. Aethyr begins sublimating back into the physical universe and responds by linking its mind with that of Mr. Mxyzptlk, to use the imp's powers to survive the transition to corporeality. Mxyzptlk uses his new power to lay waste to his home dimension of Zrfff, then bombards Metropolis with the Kryptonite-irradiated remains of Argo City. As Aethyr emerges, the Phantom Zone ceases to exist, releasing all its inmates. Mxyzptlk's mind becomes a permanent part of Aethyr's new form and he reabsorbs the Zoners into his-/itsself before vanishing to recreate Zrfff in his/its own image. NOTES: Final issue of DC Comics Presents. The canonicity of this story, written by Steve Gerber and described on the cover as "An Untold Tale of the pre-Crisis Universe," is uncertain. Its flashbacks to Krypton and to the origin of the Aethyr are consistent with previous Earth-One accounts and can probably be considered canonical, but the same may not be true for the present-day events and ambiguous finale. (It's not clear whether by re-imprisoning the Phantom Zone prisoners, Mxyzptlk/Aethyr has effectively recreated the Zone.) Adventure Comics #329 (Feb. 1965) had previously indicated that Htrae survives to the 30th century, although in this timeline, Mxyzptlk/Aethyr may have eventually recreated the Bizarros, which would seem to be within his/its power. DC Comics Presents #97 (Sept. 1986)
  Imaginary Story: "Whatever Happened to the Man of Tomorrow?" A group of Legionnaires, accompanied by Supergirl (years before her death), gives Superman a trophy of his final and greatest victory. NOTES: This Imaginary Story is not technically part of continuity. Superman v.1 #423 (Sept. 1986)
  Imaginary Story: "Whatever Happened to the Man of Tomorrow?" The Legion's trophy gives Superman the clue to defeating Mr. Mxyzptlk. The adult Legion of Super-Villains appears on the scene to gloat, but the villains flee when they realize they may be injured. NOTES: This Imaginary Story is not technically part of continuity. This was the final appearance of the adult LSV. Action #583 (Sept. 1986)
The Future
21st Century Earth is devastated by World War III, which culminates in a limited nuclear conflict. The population is cut nearly in half and it takes almost a century before order is fully restored. Many records of the 20th century are lost. NOTES: The existence of an atomic war in the Legion's timeline was first suggested by Saturn Queen in the Adult Legion story in Superman #147 (Aug. 1961). History of the DCU #2 (Nov. 1986)
2050 While returning to their own era from Superboy's time, a group of Legionnaires briefly appears in the real, rather than Pocket Universe, 21st century. NOTES: These events take place concurrently with Legion v.3 #23 (June 1986). (Legion v.2 #287, 5.82)
  At some unknown time, Darkseid, lord of Apokolips, goes into suspended animation, where he remains until 2984. Apokolips later moves to Earth's dimension. (Legion v.2 #287, 5.82)
  Waylaid by the Lord of Time while attempting to return to the 30th century, Karate Kid finds himself in the world of Earth After Disaster, where he meets Kamandi. Karate Kid speculates that Kamandi may have a counterpart in the Legion's timeline, perhaps one of the Legionnaires. He and Diamondeth eventually make their way to the Legion's timeline. NOTES: Karate Kid's next chronological appearance is in Superboy and the LSH #244 (Oct. 1978). This story strongly suggested that Kamandi's Adventures took place in an alternate version of the 30th century. Most of his other appearances, however, implied that the Great Disaster took place sometime in the 21st century, placing Kamandi in either the late 21st or early 22nd centuries. Kamandi #58 (8-9.78)
23rd Century The Great Wars of the 23rd century occur. (Tales of the Legion #321-323, 3-5.85)

28th Century The galaxy is ravaged by the Great Wars of the 28th Century. Although this era produces many technological advances, including anti-matter fusion power, nega-shielding, gamma-energy blasters, warping mists, and the Atomic Axe, the devastation of the wars causes many of these discoveries to be lost for more than 200 years. (Superboy v.1 #210, 8.75)
2729 A being known only as the Engineer constructs a mobile, artificial world populated by androids designed to amuse him and protect him from attack. After the Engineer's death, the androids continue to carry out their programming, periodically attacking anyone who approaches the planet. (Legion v.2 #262, 4.80)
