Question: What is the middle name of the villain Superman and Batman team up against in Superman/Batman: Public Enemies?
Context: Superman (1948) is a 15-part black-and-white Columbia film serial based on the comic book character Superman.  It stars an uncredited Kirk Alyn (billed only by his character name, Superman; but credited on the promotional posters) and Noel Neill as Lois Lane.  Like "Batman", it is notable as the first live-action appearance of Superman on film and for the longevity of its distribution.  The serial was directed by Thomas Carr, who later directed many early episodes of the "Adventures of Superman" television show, and Spencer Gordon Bennet, produced by Sam Katzman and shot in and around Los Angeles, California.  It was originally screened at movie matinées and after the first three scene-setting chapters, every episode ends in a cliffhanger.  The Superman-in-flight scenes are animations, in part due to the small production budget. Before Ambush Bug received his own mini-series, he appeared in "DC Comics Presents" #52 and #59 as a villain, later becoming a hero in "Supergirl" #16.  He discovered that Clark Kent is really Superman in "Action Comics" #560; revealed his origin in issue #563; and in issue #565, tried (and failed) to get Batman, Superman, and Wonder Woman to appear in his mini-series.  In "DC Comics Presents" #81 (his last pre-series appearance), he switches bodies with Superman for 48 hours. The Mayfair Exponential Game System or MEGS is a rules system developed for role-playing games.  The name was what fans called the game system for "DC Heroes", which was later used for "Underground" (1993).  It is noteworthy for its use of an exponential system for measuring nearly everything in the game.  This system makes it possible to have both cosmically-powered characters and ordinary human characters meaningfully interact within the same universe.  For example, in "DC Heroes", the first game to use MEGS, Superman's strength is several orders of magnitude more than Batman's.  With the MEGS system, however, this large difference in strength is scaled down.  So, while Superman would still have a clear advantage in a brawl, Batman is at least able to hold out for a while, mirroring how superhero combat often operates in comic books. Kevin James Anderson (born March 27, 1962) is an American science fiction author with over 50 bestsellers.  He has written spin-off novels for "Star Wars", "StarCraft", "Titan A.E." and "The X-Files", and with Brian Herbert is the co-author of the "Dune" prequel series.  His original works include the "Saga of Seven Suns" series and the Nebula Award-nominated "Assemblers of Infinity".  He has also written several comic books, including the Dark Horse "Star Wars" collection "Tales of the Jedi" written in collaboration with Tom Veitch, Dark Horse "Predator" titles, and "The X-Files" titles for Topps.  Some of Anderson's superhero novels include "Enemies & Allies", about the first meeting of Batman and Superman, and "The Last Days of Krypton", telling the story of how Superman's planet Krypton came to be destroyed. Public Enemies is a 2009 American biographical mob drama film directed by Michael Mann and written by Mann, Ronan Bennett and Ann Biderman.  It is an adaptation of Bryan Burrough's non-fiction book "Public Enemies: America's Greatest Crime Wave and the Birth of the FBI, 1933–34".  Set during the Great Depression, the film chronicles the final years of the notorious bank robber John Dillinger (Johnny Depp) as he is pursued by FBI agent Melvin Purvis (Christian Bale), Dillinger's relationship with Billie Frechette (Marion Cotillard), as well as Purvis' pursuit of Dillinger's associates and fellow criminals Homer Van Meter (Stephen Dorff) and Baby Face Nelson (Stephen Graham). Superman/Batman: Public Enemies is a 2009 original direct-to-video animated superhero film adaptation of "Public Enemies"—the opening story arc of DC Comics' "Superman/Batman"—which focuses on Superman and Batman teaming up to prevent a meteorite from striking Earth and take down Lex Luthor, who has been elected President of the United States.  The film is the sixth in the line of the DC Universe Animated Original Movies line released by Warner Premiere and Warner Bros.  Animation.  Voice actors from the DCAU reprised their roles, although it is not a DCAU production and is said not to be connected with that universe beyond sharing of voice actors.  The film is directed by Sam Liu. Alexander Joseph "Lex" Luthor is a fictional supervillain appearing in American comic books published by DC Comics, though on occasions he has established himself as an antihero.  He was created by Jerry Siegel and Joe Shuster.  Lex Luthor first appeared in "Action Comics" #23 (April 1940) and has since endured as the archenemy of Superman. The New Batman/Superman Adventures is a name given to a package series that combined "" with "" and "The New Batman Adventures" produced by Warner Bros.  Animation.  It aired from 1997–2000 on Kids' WB.  Each half-hour episode in the hour-and-one-half block featured either a single repeat from the original "Superman: The Animated Series" run, the original "Batman: The Animated Series" run, or a brand new story featuring Batman made specifically for this series, drawn in an animation style to match "Superman: The Animated Series".  These new stories focus more on Batman's supporting cast and introduced new characters such as Tim Drake.  The two animated universes were united in the "Superman" episode "World's Finest", which tells the story of Batman and Superman's first meeting.  The new Batman episodes that began airing in the Fall 1997 season were later released as a DVD box set of "Batman: The Animated Series" as Volume 4.  New Superman episodes that later aired in the Fall 1998 season and onward are now considered to be the third season of "Superman: The Animated Series". DC Universe Presents is the name of two DC Comics publications.  The first is part of the UK 'Collector's Edition' line of DC Comics published by Titan Magazines.  Beginning March 2007, it was originally titled Superman Legends and was published alongside "Batman Legends".  Titan also later released several other DC comics following on from the success of Superman and Batman Legends.  The book was retitled as DC Universe Presents at issue 33 but despite the change in title and some of its content, the magazine continued the issue count of Superman Legends. Ra's al Ghul (Arabic: رأس الغول‎ ‎ "Raʾs al-Ġūl"; "Ghoul's Head" or "Demon's Head") is a fictional supervillain appearing in American comic books published by DC Comics, commonly as an adversary of the superhero Batman.  Created by editor Julius Schwartz, writer Dennis O'Neil and artist Neal Adams, the character first appeared in "Batman" #232's "Daughter of the Demon" (June 1971).  The character is one of Batman's most enduring enemies and belongs to the collective of adversaries that make up Batman's rogues gallery, though given his high status as a supervillain, he has also come into conflict with Superman and other superheroes in the DC Universe.
