Lugalbanda: Lugalbanda (Sumerian: lugal-banda , "young/fierce king") is a character found in Sumerian mythology and literature.  Lugalbanda is listed in the postdiluvian period of the Sumerian king list as the second king of Uruk, saying he ruled for 1,200 years, and providing him with the epithet of "the Shepherd".  Whether a king Lugalbanda ever historically ruled over Uruk, and if so, at what time, is quite uncertain.  Attempts to date him in the ED II period are based on an amalgamation of data from the epic traditions of the 2nd Millennium with unclear archaeological observations.

The Cisco Kid: The Cisco Kid is a fictional character found in numerous film, radio, television and comic book series based on the fictional Western character created by O.

Contender (stock character): A contender is a stock character found in stories, television series, films, and other works depicting the development and triumph of an individual through athletic achievement.  The typical storyline of the contender is one of an (often young) individual with raw natural talent, who is hindered by a shortage of either knowledge of the sport, discipline, or indeed something as simple as confidence.  Through the encouragement of a coach or other guiding figure, for instance a wise old man or a magical negro, the contender overcomes previously insurmountable limitations and achieves his or her potential or even beyond, usually by some sort of victory, for instance in an athletic competition.  Alternatively, they may lose in the competition but nevertheless gain in some other, perhaps greater way, such as through genuine respect from their opponents for their endeavours.  After all, what matters is "not the winning, but the taking part".

Cartman first appeared, originally named Kenny, in prototypical form in a 1992 animated short "Jesus vs. Frosty", and a 1995 animated short "Jesus vs. Santa", and first appeared on television in the pilot episode of "South Park", "Cartman Gets an Anal Probe", on August 13, 1997.

Xana: The xana is a character found in Asturian mythology.  Always female, she is a creature of extraordinary beauty believed to live in fountains, rivers, waterfalls or forested regions with pure water.  She is usually described as small or slender with long blonde or light brown hair (most often curly), which she tends to with gold or silver combs woven from sun or moonbeams.  The origin of the Asturian word "xana" is unclear, though some scholars see it as a derivation from the Latin name for the goddess Diana.  References to where the mythological xanas lived are still common in Asturian toponyms.  They also appear in Eastern Galician and Cantabrian mythology (Anjanas).
