"Did you honestly believe a fifth-dimensional sorcerer would resemble a funny little man in a derby hat?" from Whatever Happened to the Man of Tomorrow.
The mischievous magical imp, Mr. Mxyzptlk - pronounced Mix-yez-pittle-ick, in case you were struggling, and that's according to my Ultimate Guide to The Man of Steel - hails from the Fifth-Dimension and visits Earth every ninety days to, well, annoy Superman. And when you've got almost limitless power, it's not such a difficult task.
We've seen Mxy warp Superman's body; animate the Daily Planet building; create red kryptonite for Lex Luthor; he's even handed over his powers to the Joker for a short period of time, and watched in horror as the psychotic clown decimated Earth. With Mxy, anything goes; the possibilities are endless. So what'll the Thoughtballooners come up with? Stayed tuned during the week - and as always, join in the fun!
