Trivia

 * In the Guilty Gear fighting game series, the character Ky Kiske has an overdrive called "Ride the Lightning." In addition to a thoroughly heavy metal soundtrack, the Guilty Gear series contains a multitude of music references.  Ky's special move is undoubtably named after the Metallica album "Ride the Lightning."  Whether ArenaNet plays Guilty Gear is unknown.
