Mr. Mxyzptlk

A mischievous imp from the fifth dimension (the realm of Zrfff), Mr. Mxyzptlk possesses virtually unlimited reality-warping power and visits the three-dimensional world solely to torment Superman with pranks and chaos. The only way to send him home for 90 days is tricking him into saying or spelling his name backwards.

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.
