Batman is a man who dresses like a bat. Spider-Man is a man with the powers of an arachnid. Aquaman is worthless and should have been kicked out of the Superfriends a long time ago.
And then you have Melkman, which is a man who has the powers of a Melky Cabrera. What can a Melkman do? It depends on the year. Just when you think your superhero is fat Batman (in, say, 2008), he suddenly turns into the Incredible Hulk (an All-Star MVP 2012). Being the Melkman brings with it great responsibility; this man appears not-quite-ready to accept his.
