Mr. Mxyzptlk

Few characters in DC's vast Silver Age playground have proven as delightfully, stubbornly enduring as Mr. Mxyzptlk, who first bedeviled readers in the pages of Superman #135 back in 1960, courtesy of the legendary Jerry Siegel and artist Al Plastino. Over 65 remarkable years — spanning Silver Age mischief all the way to 2025 — this imp has accumulated 103 catalog appearances and three collector-significant key issues, a testament to just how deeply he's burrowed into DC's DNA. His adventures have carried him across flagship titles like Superman and Batman: The Brave and the Bold, where he shares the page with icons including Clark Kent, Lois Lane, Bruce Wayne, Batman, and Green Lantern — elite company that speaks to his standing as one of DC's most persistently fascinating figures. If you're building a serious DC collection, Mr. Mxyzptlk isn't a footnote — he's a throughline.
