Superman's Pal, Jimmy Olsen #28

In a wild twist of fate, Jimmy Olsen is hurled into the distant future when Superman’s super-speed during a hurricane sends his helicopter through the time barrier. There, he discovers a shocking truth: in this far-off year, he’s infamous as the man who killed Superman using kryptonite. Now branded a criminal, he’s captured by future authorities and sent back to the 20th century to face trial for a crime he doesn’t remember committing.

When Prof. Potter accidentally gives Jimmy Olsen the wrong pill for his toothache, Jimmy grows into a towering giant—over a dozen stories tall—with the mind of a child. As Superman scrambles to help, he stumbles upon the antidote hidden in the Flying Newsroom, just as Jimmy’s new size threatens to bring chaos to Metropolis.
