Alfred Bester is a Babylon 5 character played by Walter Koenig. He is a senior Psi Cop and a recurring antagonist in the series. J. Michael Straczynski named the character after the science fiction writer Alfred Bester, since telepathy is a recurring theme in his work (most notably The Demolished Man, which partly may have inspired the Psi corps and the "death of personality" legal punishment in the Babylon 5 universe).
