->As far-out as it sounds, somehow my mind alone was catapulted forward through time into my own future! I can only guess-- But I somehow switched minds with myself-- meaning Superman's mind is now in the Superboy body I left behind in Smallville thirteen years ago!

''A Mind-Switch In Time'' was a ''Franchise/{{Superman}}'' storyline published in 1983 and told through two titles: ''Superman Vol. 1'' #380-382 and ''The New Adventures of Superboy'' (or Superboy Vol. 2) #38.

In 1982, Superman flies into the time-barrier to carry out research on the habits of prehistoric men. However, he finds a massive tear disrupting the time-stream. Undaunted, he decides to plow his way through it.

However, he finds a massive tear disrupting the time-stream. Undaunted, he decides to plow his way through it.
Against all odds, past and present Kal-El crash into each other. Since time travel physics dictate nobody can co-exist with himself at the same time, for which time-travelers become immaterial while visiting times where they already exist, both Clarks become intangible and phase into each other before being forcefully tossed back to their times of origin.
Nonetheless, their violent clash has had an unexpected result: teen and adult Clark Kent have swapped bodies.

Superman easily tanks an energy beam\\
'''Superboy:''' You know, you shouldn't knock "snappy patter"! It's a handy way for someone like me to keep up a sunny disposition when I have to take time out of a busy day to deal with someone like you! Know what I mean?\\
'''Biker:''' I--I don't believe it-- Not even a smudge! You just ain't human!

* TheReasonYouSuckSpeech: Superman finally runs out of patience and beats Lex Luthor up while pointing how stupid and short-sighted Lex really is.
-->'''Superman:''' No, we can't have trash like you cluttering the streets-- or wouldn't you love to have someone trip over you and get hurt? Isn't that what you live for... Menacing innocent people with your insane gimmicks? Face it, Lex Luthor... The future would be better off without you! You're a menace! Look at your latest trick!

I'd be doing the world a favor by putting an end to you right now... Before you grow up to be an even greater menace!

-->'''Superboy:''' So long, Ma and Pa. I'm off to the [31st] century for this month's regular Legion meeting.
* TooDumbToLive: After running into young Lex, Superman judges that his nemesis is suicidally stupid: If Luthor had succeeded in killing him, he would have been killed by the next world-destroying entity who dropped by and could only be driven back by Superman.
* TrappedInThePast: Superman travels to the past and gets stuck in 1969.
* TimeLoopTrap: Luthor traps Superman into a loop, forcing him to relive 1969 Thanksgiving Day over and again.
* ToTheFutureAndBeyond: Inverted. Superman gets trapped into a time-loop. Since he cannot break it by time-travelling to the future, he decides to test Einstein's theory that time is not linear but a full loop: he flings himself into the past and travels the entire timestream backwards until emerging one day after the time-loop.
* UnderestimatingBadassery: When Lex demands to know how Superboy broke out of the time loop, Superman replies he decided to test whether Einstein was right about time working as a gigantic loop. Lex admits grudgingly he was wrong about his nemesis' head being full of air instead of brains.
-->'''Lex Luthor:''' All right-- So maybe there is more between your ears than cottage cheese as I always thought, Superboy--
* WeHaveReserves: Euphor's reaction to his minions getting killed by their own powers is uttering "How tragic! Oh, well-- There's more where they came from!" and transforming another person.
* WellIntentionedExtremist: Euphor increases his power by absorbing Metropolis' negative emotions until he is powerful enough to put the whole city under his total mind-control. Even so, he seems to believe he is really the good guy, since he privately insists that he is just helping people and Superman deserves to be kicked out of Metropolis for not removing its citizens' unhappiness.
* WithGreatPowerComesGreatInsanity: Euphor becomes more powerful and more insane as he mass-absorbs negative emotions until he has become a crazy overlord who can give Superman a hard time.
* YouCantFightFate: While in the past, Superman escapes from still another Lex Luthor's deadly trap. Nonetheless, Superman's patience at last has been exhausted, to the point he considers getting rid of young Lex "before [he grows] up to be an even greater menace", and he has to be talked down by Chief Parker. Feeling ashamed, Superman reminds himself once again he can NOT change the past.
-->'''Superman:''' Wh-What came over me? I... I almost killed him...! B-but that's insane! As Superman, I know I couldn't have done it! I can't change the past... and Luthor is still alive in my time!
----
->As far-out as it sounds, somehow my mind alone was catapulted forward through time into my own future! I can only guess-- But I somehow switched minds with myself-- meaning Superman's mind is now in the Superboy body I left behind in Smallville thirteen years ago!
-->-- '''Superboy'''
''A Mind-Switch In Time'' was a ''Franchise/{{Superman}}'' storyline published in 1983 and told through two titles: ''Superman Vol. 1'' #380-382 and ''The New Adventures of Superboy'' (or Superboy Vol. 2) #38. Cary Bates and Curt Swan were the creative team assigned to the ''Superman'' title, and Paul Kupperberg and Kurt Schaffenberger were responsible for the ''Superboy'' side of the crossover.
In 1982, Superman flies into the time-barrier to carry out research on the habits of prehistoric men. However, he finds a massive tear disrupting the time-stream. Undaunted, he decides to plow his way through it.
In 1969, ComicBook/{{Superboy}} volunteers in Smallville's Soames Reform School during Thanksgiving Day, tries and fails to convince ComicBook/LexLuthor to drop his petty grudge once again, and flies into the time-barrier to attend a ComicBook/LegionOfSuperHeroes meeting in the 30th century. However, he finds a massive tear disrupting the time-stream. Undaunted, he decides to plow his way through it.
Against all odds, past and present Kal-El crash into each other. Since time travel physics dictate nobody can co-exist with himself at the same time, for which time-travelers become immaterial while visiting times where they already exist, both Clarks become intangible and phase into each other before being forcefully tossed back to their times of origin.
Nonetheless, their violent clash has had an unexpected result: teen and adult Clark Kent have swapped bodies.
Superboy finds himself fifteen years in the future, stuck in his older self's body, and finds himself surprised to learn about his future life: he lives in Metropolis now, he's a renowned journalist and newscaster, -despite Pa and Ma's advising him to lie low-, her old flame ComicBook/LanaLang is her co-host but he has a romance with fellow Daily Planet co-worker ComicBook/LoisLane, he has found his long-lost [[ComicBook/{{Supergirl}} cousin]] and other Kryptonian survivors…
Superboy is adapting to his future self's life when he comes across a trouble he cannot handle: an emotion-eater called Euphor is mind-controlling Metropolis. Initially, Euphor seemed to mean well, but absorbing massive quantities of negative emotions is simultaneously increasing his power and insanity. Now Euphor has become convinced that he should take Metropolis' unhappiness -together with his free will- away for their own good, and Superman deserves to be kicked out of Metropolis for failing to fix their psychological issues. And he is willing to use brainwashed human shields to force the Man of Steel out of his own city. Superboy knows his older self would know how to handle Euphor, but he is not experienced enough to stop him.
Meanwhile in the past, Superman finds himself stuck in his teenager body, reliving the same day over and again, unable to tell anyone about being adult Clark stuck in a time loop. He cannot break the loop by going forward in time because of the disruption blocking the time stream. Clark is certain that he knows who the culprit behind his predicament is, but assuredly correct assumptions do not solve his problem; specially if he cannot act on them.

'''Biker:''' I--I don't believe it-- Not even a smudge! You just ain't human!

Menacing innocent people with your insane gimmicks? Face it, Lex Luthor... The future would be better off without you! You're a menace! Look at your latest trick!
