Here is a lovely panning shot of the Melog from the episode "Enemy With My Face." An interesting fact that someone once told me when I ran the Episode Review Website was that the word "Melog" is "Golem" spelled backwards! I found that quite interesting, as a Golem is defined as an "Artificial figure constructed to represent a human being and endowed with life." Golems are found in a lot of fantasy literature, most notably in fantasy role-playing games, so it comes as no great surprise that J. Michael Straczynski wrote this episode!
