Joseph Meach was a diver who had fallen on hard times. In an attempt to draw publicity to himself, Meach set up a water tank on a sidewalk in MThe Composite Superman then created situations for Superman or Batman to handle, but which he intentionally sabotaged to humiliate the heroes, then sorted them out himself. Superman and Batman's attempt to expose him by using robot duplicates failed due to Composite Superman's ability to read their minds. Just before Meach could reveal the heroes' secret identities, the powers he gained from the statues faded away. Meach tried to write down the secret of his powers in the Superman Museum, but his memory faded before he could finish (though he managed to write down about the lightning striking the statues, but nothing more).
He later had a funeral for him by the Justice League.
