This cowgirl's wilder than a buckin' bronco!
- —Ruby about Garnet
Ruby (ルビィ, Rubī?) is a minor character in Final Fantasy IX. She works as one of Tantalus Theater Troupe's actors and is the only female of the group. She plays the lead heroine in Tantalus's production of the famous play I Want to Be Your Canary.
Ruby wears a low-cut white blouse with short sleeves. Her hourglass figure is cinched in by a brown corset-like belt. Short green panels grace the sides of her teal, asymmetrical skirt. She wears opaque white tights, pink shoes, short white gloves with brown ribbons, and a brown choker. Her hair is grey, but much of it is covered by a large, light blue bandana.
When left behind by the rest of the Tantalus troupe, Ruby shows off her entrepreneurial nature by founding her own mini theater. The other Tantalus members fear her scolding and work behind her back to escape her temper. Still, the Tantalus members begin their adventure while cheerfully leaving Ruby behind, briefly forgetting all about her. She would personally be happier if her troupe would just be actors and not thieves, but she still does her best to cheer up anyone who needs it.
In the English localization Ruby has a strong North American southern accent. In the Japanese version, she speaks with an Osaka-ben dialect. In the Italian version, she has a Spanish accent. In the German translation, she speaks a Cologne dialect, and in Spanish, she has an Argentine dialect.
Ruby was going to play the role of Cornelia in Tantalus's production of the play I Want to be Your Canary, but she had the part unintentionally stolen from her by Princess Garnet. During Tantalus's escape from Alexandria, Ruby gets left behind. She starts up her own theater and remains there, even after the rest of Tantalus return to Lindblum and begins to work with the famous actor Lowell Bridges although, he feels his talents are wasted in Ruby's small theater and continually complains about everything. Ruby is the owner of Superslick, an item required to fix Mognet Central.
Even after founding her own theater in Alexandria, Ruby reunites with Tantalus at the end of the game for their final performance of I Want to be Your Canary.
- During one of the opening cutscenes, if the player chooses Queen Brahne 64 times when Baku asks Zidane who they are meant to kidnap, Ruby will storm into the room and move the conversation onwards.
- She is one of the few characters within the "silent" Final Fantasy games to be shown with an accent. The only other accented characters include Faris Scherwiz in the Anthology port of Final Fantasy V, Dr. Odine and Ultimecia in American/European localizations of Final Fantasy VIII, and the non-playable dwarves of Conde Petie.
- In the Advance and successive remakes of the original Final Fantasy, Ruby is one of the automatic names the player can choose for the White Mage job.
