One of the more popular series of Dark Horse Comics' short-lived superhero universe Comics Greatest World, which showcased different types of superheroes throughout its four environments. X represented the '90s Anti-Hero, who was determined to rid the city of Arcadia of the rampant crime and corruption that plagued it and was willing to kill anyone who stood in his way. A single diagonal slash across your face meant that you were warned and you'd better not break his rules again; if he completed the X, he killed you. No exceptions.His first story was in Dark Horse Comics #8-10 back in 1992, which was later reprinted as X: One Shot to the Head. He started the Comics Greatest World weekly 16-issue launch in 1993, where he featured prominently in all four Arcadia issues. February 1994 saw the first issue of his ongoing series, which lasted 25 issues, the last of which was published in April 1996.Dark Horse is currently rebooting this series, along with Ghost, who also resided in Arcadia.No relation to X/1999, the X-Universe video games, X-COM, or the Punk Rock band X.
X provides examples of:
- Anyone Can Die: No matter if you're a thug, a corrupted cop or even the mayor, if you're marked by X, then beware.
- Author Appeal: Being part of Dark Horse in those years and having his own comic book, the famous '90s Anti-Hero creator Frank Miller put his distintive seal to X making the covers of issue no.1 for Comics' Greatest World◊ and the One Shot to the Head◊ compilation, both having X as The Protagonist.
- Black and Gray Morality: X's methods are questionable, to say the least, but the criminals and police officers he goes after are no less corrupt.
- Determinator: X is willing to do whatever it takes to clean up the streets of Arcadia.
- Exact Words: The first mark is a warning. The second mark is death. If the X is completed on your face or an image of your face, then X will kill you, even if he wasn't the one who put it there.
- Guns Akimbo: X frequently wields a pair of pistols, as does Ghost who sometimes crosses paths with him.
- Handicapped Badass: At the end of the fourth issue of Arcadia arc of CGW, X takes off the mask and it's revealed he wears an Eyepatch of Power, which is also the reason why in his costume only can be seen one eye, being the other one covered with the X.
- Healing Factor: Throughout the series, X is repeatedly shot, stabbed, burned, blown up, run over, etc., but he always heals from his injuries eventually.
- Hell-Bent for Leather: The complete X outfit was made in black leather with some red on it.
- Love Hate Relationship: With Ghost. Not specifically a "relationship" but they can be enemies as well allies, depending of how their paths are crossed. Also Ghost appeared in some of X's comics and viceversa.
- Marked to Die: X's trademark. A single diagonal slash across your face meant that you were warned and you'd better not break his rules again; if he completed the X, he killed you. No exceptions.
- Mysterious Past: No one really knows who X is or where he came from, though clues to his origin are sprinkled throughout the series and is fully revealed during the final issues.
- One-Letter Name: X
- Red Is Violent: As most of '90s Anti-Hero characters of the time, X also has red as part of his outfit, mostly in the X on his head, the Badass Cape and the cords on his wristpads and boots.
- The Protagonist: First of the Arcadia arc of CGW and later with their own ongoing solo series.
- Wall of Weapons: The X copycat killer has a small room featuring walls completely covered in guns and blades in his house.
- Well-Intentioned Extremist: X wants to clean his beloved Arcadia of corruption, and if he has to kill people to achieve it, then he'll do it.
- Wretched Hive: Arcadia is an orderly, smoothly run machine of a city. This is a world of shadow, danger, and bloody retribution. It is a city of corrupt officials and organized crime. The policemen who are not on the take are criminals in their own right.
