Gast Faremis is a minor, yet important character in Final Fantasy VII. A biologist, he used to be the head of Shinra's Science Research Department. Unlike his colleagues, the later successor Professor Hojo and Dr. Hollander, Gast pursued wisdom for its own sake, rather than using it to gain power.
In the original Final Fantasy VII his name is given as simply Professor Gast. His character profiles in the Final Fantasy VII Ultimania Omega and Final Fantasy VII 10th Anniversary Ultimania guides give his full name as ガスト・ファレミス, "Gast Faremis", although his surname hasn't seen an official romanization. In the Japanese version Gast's full name is mentioned in one of the books in the Shinra Headquarters library.
Gast wears the typical white coat of a scientist, over a brown shirt, blue tie and white trousers. His hair is short and meets his forehead in a widow's peak, and he sports a drooping mustache and dark glasses.
An intelligent man, Gast never saw gain in abusing his knowledge and used it for what he assumed to be good. He has a kind heart and is a keen listener, eager to learn more about the subjects he studies.
Jenova is an ancient organism Shinra excavated from a 2,000-year-old structure, and Gast drew the wrongful conclusion that Jenova was a member of the Cetra, a species of humans said to have been able to commune with the Planet itself, long thought extinct. Shinra sent Hojo and Lucrecia Crescent to assist him in his research to create the Jenova Project, its goal to create a human with the powers of the Cetra to lead Shinra to the Cetra's fabled Promised Land. Gast's research led Hojo to inject Lucrecia with Jenova cells to make a new race of Cetra through Hojo and Lucrecia's unborn child. This child was called Sephiroth.
Gast left the project upon discovering Jenova is not a Cetra, and continued his research on the Cetra in his laboratory at Icicle Inn. When departing Shinra, he helped a captive Cetra, Ifalna, the true last remaining Cetra, escape. This detail is revealed in Crisis Core Complete Guide. After leaving Shinra, the two migrated to Icicle Inn and went into hiding.
Gast records the interviews he conducts on Ifalna, where he learns the truth about Jenova and the Promised Land. He falls in love with Ifalna, and they have a daughter: Aeris. They are tracked down by Shinra, and Hojo kills Gast while capturing Ifalna and Aeris. Hojo keeps Gast's true fate a secret from Shinra, and what happened to Gast's body is unknown.
Gusto (ガスト?, the same katakana as Gast's first name) is the name of a Japanese family restaurant chain. The katakana of Gast's surname (ファレミス, Faremisu?) is similar to the common Japanese abbreviated term for a family restaurant (ファミレス, famiresu?). This may be relevant, as in the Japanese version Gast's full name is discovered in the Shinra HQ library where Mayor Domino and his assistant Hart (ハット, Hatto?, lit. Hut) also are, whose names are puns for Domino's Pizza and Pizza Hut.
The katakana spelling of Gast's first name is closer to the Nordic name "Gusto".
In Latin the word farimus, similar to Gast's surname Faremis, means "lighthouse".
- Gast is one of the few people Sephiroth respects in Final Fantasy VII.
