Don Cameron, Ira Yarborough and Stan Kaye bring Mr. Mxyztplk back in Action 102 (Nov. 46), as the imp learns about the legend of Aladdin’s lamp, and decides to create one himself.
Mr. Mxyztplk gives people their wishes, but in his fashion. When people discover their wishes have become nightmares, they beg for things to return to normal, but Mxyztplk refuses.
It’s Lois Lane who outwits the imp, rather than Superman. She asks for three wishes, and then uses them to remove Mxyztplk’s powers, and have him encased in steel. With no way to escape, the imp has little choice but to say his name backwards, and return to the 5th Dimension.
