Gex is a platform video game trilogy, developed by Crystal Dynamics, that details the adventures of an anthropomorphicgecko named Gex. Gex has a passion for television, which makes him a target for the cybernetic being Emperor Rez, who is determined to overthrow The Media Dimension, the "world" of television. He has served as the mascot of Crystal Dynamics, appearing on their company logo for several years until 2000. In the North American version, Gex is voiced by comedian Dana Gould throughout the entire series; the United Kingdom version features Gould, Leslie Phillips and Danny John-Jules as Gex's voice throughout the series. The games are largely inspired by American TV culture. Gex contributes to the games with wise-cracking remarks laced with media and references to popular culture. Gex appears as an unlockable character in the North American and European versions of Hot Shots Golf 2 and Mad Dash Racing. The Gex series has sold a combined total of over 15 million copies for all platforms.
Gex is a smart aleck, wise-cracking gecko. Gex lives with his family in Maui, Hawaii. He spends his days with his friends, surfing, playing the ukulele and throwing poi parties down on the beach with the local lady lizards. After his father's death, he begins watching mass amounts of TV to get over the tragedy. He eventually inherits over twenty billion dollars from his deceased great uncle, and buys the world's largest television. He has his own island hideaway called the GEXCave located in the South Pacific. His catchphrase is "It's tail time!", due to his primary attack being tail whips. Gex is voiced by Dana Gould in all three installments in North America. The PAL versions feature three separate voice actors; Dana Gould in the original game, Leslie Phillips in the second game, and Danny John-Jules in the third game.
Rez is a megalomaniac, cybernetic entity, and the main antagonist of the series. His one true ambition is to control the entire Media Dimension under his own control and ensure the longevity of bad TV shows and Z-Grade movies. His entire essence is made up of Liquid Rez, liquid noise spread throughout the series. He also claims to be Gex's father as a homage to Star Wars. Rez is voiced by Bruce Robertson.
Agent Xtra is Gex's crime-fighting partner, who also loves TV as well. She is kidnapped by Rez, and communicates to Gex through video signals in mission control. She is portrayed in live-action sequences by Marliece Andrada.
Alfred is Gex's butler. He is a turtle who wears a bow tie and glasses. He provides Gex with constant help to defeat Rez. He is voiced by Marc Silk.
Rex is a small, red Tyrannosaurus rex and Gex's prehistoric ancestor. He is frozen in a block of ice that Gex melts to set him free.
Cuz is Gex's overweight cousin and seems to be a leopard gecko. He is saved by Gex after being locked in a cage by the Gangsters.
Gex's Dad who works for NASA by doing various research projects. He and ten other volunteers are chosen to eat tapioca pudding in zero gravity, though their rocket explodes due to a Band-Aid floating into one of the fuel tanks, killing them. His mother later moves to California, and after gaining money inherited from Gex's great-uncle, Charlie, she purchases 51 percent ownership in NASA, fires everyone, sells the rockets to some third world countries, and converts Mission Control into "Space Monkeys", a theme restaurant featuring robotic dancing chimps wearing spacesuits. In the novel, Rez claims that he is Gex's real father and became the way he was after the explosion, whether this is true or not is unclear, although Rez makes the same claim in Gex 2 but with a different story.
Future
A fourth entry was in development for the PS2 but was canceled, with only concept art existing of the project. On February 17, 2015, Square Enix announced that it will allow developers to create games based on some of their old Eidos intellectual properties via the Square Enix Collective project, including the Gex intellectual property.
