Over the years,Superman and his secret identity Clark Kent have made both official and unofficial cameos in the Marvel Comics universe. However, the DC Comics hero's best secret cameo is one that most people missed, as the Man of Steel made a hidden cameo in The Death of Captain Marvel: The Graphic Novel. While it's not the easiest to see, Superman's kiss curl, cape, and part of his costume can be seen hiding behind a group of mourning Marvel heroes.
