Snakes are elongated, legless, carnivorous reptiles of the suborder Serpentes that can be distinguished from legless lizards by their lack of eyelids and external ears. Like all squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with many more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads with their highly mobile jaws. To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Living snakes are found on every continent except Antarctica, in the Pacific and Indian Oceans, and on most smaller land masses — exceptions include some large islands, such as Ireland and New Zealand, and many small islands of the Atlantic and central Pacific. More than 20 families are currently recognized, comprising about 500 genera and about 3,400 species. They range in size from the tiny, 10 cm-long thread snake to the Reticulated python of up to 8.7 meters (29 ft) in length. The fossil species Titanoboa cerrejonensis was 15 meters (49 ft) long. Snakes are thought to have evolved from either burrowing or aquatic lizards during the mid-Cretaceous period, and the earliest known fossils date to around 112 Ma ago. The diversity of modern snakes appeared during the Paleocene period (c 66 to 56 Ma ago). The oldest preserved descriptions of snakes can be found in the Brooklyn Papyrus. Most species are nonvenomous and those that have venom use it primarily to kill and subdue prey rather than for self-defense. Some possess venom potent enough to cause painful injury or death to humans. Nonvenomous snakes either swallow prey alive or kill by constriction.

Star Trek is an American science fiction entertainment franchise created by Gene Roddenberry and currently under the ownership of CBS and Paramount. Star Trek: The Original Series and its live action TV spin-off shows, Star Trek: The Next Generation, Star Trek: Deep Space Nine, Star Trek: Voyager and Star Trek: Enterprise as well as the Star Trek film series make up the main canon, while Star Trek: The Animated Series as well as the expansive library of Star Trek novels and comics are part of the franchise, but are generally considered non-canon. The first series, now referred to as "The Original Series", debuted in 1966 and ran for three seasons on NBC. It followed the interstellar adventures of James T. Kirk and the crew of the Starship Enterprise, an exploration vessel of a 23rd-century galactic "United Federation of Planets". In creating the first "Star Trek", Roddenberry was inspired by Westerns such as Wagon Train, along with the Horatio Hornblower novels and Gulliver's Travels. These adventures continued in the short-lived Star Trek: The Animated Series and six feature films. Four spin-off television series were eventually produced: Star Trek: The Next Generation, followed the crew of a new Starship Enterprise set a century after the original series; Star Trek: Deep Space Nine and Star Trek: Voyager, set contemporaneously with The Next Generation; and Star Trek: Enterprise, set before the original series, in the early days of human interstellar travel. Four additional The Next Generation feature films were produced. In 2009, the film franchise underwent a relaunch with a prequel to the original series set in an alternate timeline titled simply Star Trek. This film featured a new cast portraying younger versions of the crew from the original Enterprise. A sequel to this film, Star Trek Into Darkness, premiered on May 16, 2013. Star Trek has been a cult phenomenon for decades. Fans of the franchise are called Trekkies or Trekkers. The franchise spans a wide range of spin-offs including games, figurines, novels, toys, and comics. Star Trek had a themed attraction in Las Vegas which opened in 1998 and closed in September 2008. At least two museum exhibits of props travel the world. The series has its own full-fledged constructed language, Klingon. Several parodies have been made of Star Trek. Its fans, despite the end of Star Trek episodes on TV, have produced several fan productions to fill that void. Star Trek is noted for its influence on the world outside of science fiction. It has been cited as an inspiration for several technological inventions such as the cell phone. Moreover, the show is noted for its progressive civil rights stances. The original series included one of television's first multiracial casts, and the first televised inter-racial kiss. Star Trek references can be found throughout popular culture from movies such as the submarine thriller Crimson Tide to the cartoon series South Park.

Suikoden (Japanese: 幻想水滸伝, Hepburn: Gensō Suikoden) is a role-playing video game series originally created by Yoshitaka Murayama. The game series is loosely based on the classical Chinese novel, Shui Hu Zhuan by Shi Naian. Shui Hu Zhuan is rendered as 水滸伝 in Japanese, and read phonetically as Suikoden. Each individual game in the series centers around relative themes of politics, corruption, revolution, mystical crystals known as True Runes and the "108 Stars of Destiny"—the 108 protagonists who are loosely interpreted from the source material. Though the Suikoden games follow an irregular chronological sequence of events, the entire series (except for Tierkreis and Tsumugareshi Hyakunen no Toki) takes place within the same world among continuing and overlapping histories. In some cases, several characters appear in multiple installations.
