Cercyon was the King of Eleusis, and a very strong man. He stood on the roads around Eleusis and challenged passers-by to a wrestling match. The loser (always the passer-by) was murdered, though Cercyon promised his kingdom to anyone who won. He was eventually beaten and killed by Theseus, who took the kingdom of Eleusis.
