Ruby

"" is a Gem that made her official debut in "Jail Break." Currently, she is fused with Sapphire, as Garnet. Her unofficial debut was in the episode "Fusion Cuisine".

Appearance
Ruby has light red skin, dark maroon hair, and is slightly taller than Steven. She wears a maroon and dark red tank top, a light red headband around thick, outgrown hair cropped at the neck, mid-thigh length maroon shorts, and pointed violet-red boots.

Personality
She takes on Garnet's strength and courage, contrasting Sapphire, who embodies Garnet's cool nature and kindness. She seems to put the well-being of Sapphire over all else, as she immediately made sure Sapphire was safe and responded "Who cares?!" when Sapphire asked her if she herself was okay. She also seems to not be very conversant, a trait which she carries onto Garnet, as Ruby mumbles and speaks somewhat awkwardly.

Abilities
Like all Gems, Ruby can shape-shift, summon a weapon, and retreat to her gemstone to regenerate. Ruby can fuse with Sapphire to form Garnet.

Unlike Garnet, Ruby doesn't possess future vision. Joe Johnston confirmed that when she complained about not being able to "see" (use future vision), it was because she was so used to having that second sight while being fused with Sapphire.

Ruby, like all Gems, has some degree of super strength, as she was able to shake her cell by slamming her fist against the wall, causing Steven to lose his footing. It is also shown when she was able to lift Sapphire off her feet with little to no effort.

Sapphire
She and Sapphire have a romantic relationship, shown when she immediately panics when realizing that the two have been separated and becomes reckless trying to find her, running around without checking if Peridot and Jasper are around and loudly shouting for Sapphire whenever she stops singing. When she finds Sapphire, the two embrace and Sapphire kisses away Ruby's tears, showing their romantic relationship. Ruby cares strongly for Sapphire's well-being as she expressed deep concern for possible injury. Garnet's dialogue in "Love Letters" implies that Ruby and Sapphire's relationship developed gradually over a period of time.

Steven
At first Ruby seemed cold and distant towards Steven due to wanting to find Sapphire as quickly as possible. Despite this, Ruby cares deeply for Steven, as Garnet says that both her and Sapphire had already loved Steven when he asked if he made a good first impression. She also tried to stop Steven when she thought he was going to get hurt by the energy field in front of her cell.

Crystal Gems
Pearl and Amethyst have been aware of Garnet's true identities for several millennia. Their perception of the two while separated remains unknown, but given their good relationship with Garnet it can be assumed it is a positive one.

The Cluster
Upon encountering The Cluster, Ruby and Sapphire were both disturbed to the point of almost defusing. While Ruby reacted with the most verbal anger and outrage at what Homeworld had done to their fallen friends, it was Garnet's right eye that represents Ruby that started crying indicating that she was deeply saddened as well.From their own comments, as well as that of Garnet herself, it can be assumed that they knew the individual members of The Cluster.
