After teasing us for so many episodes, the identity of the fake Clark Kent running around the same time as Superman is finally revealed. I really thought it was going to be Superman Prime because his speech in the end was so whiny that it reminded me of Prime. But then with all of the magic involved, Mr. Mxyzptlk was the most logical choice.
All those panels are awesome… switching from one Superman foe to the next.
