Ruby is a member of the Crystal Gems, and an orginal gem created by Steven Universe. She is currently fused with Sapphire as Garnet.

Appearance

Ruby has light crimson skin and maroon hair. She wears a maroon tank top, a matching colored headband around her thick and fluffy, outgrown hair cropped at the neck, mid-thigh length burgundy shorts, and short, pointed maroon boots similar to Amethyst's. She is a few inches taller than Steven.

Personality

She embodies Garnet's fury and courage, contrasting Sapphire, who rather embodies Garnet's cool nature, discipline and kindness. She also appears to be a bad conversationalist, a trait which she carries onto Garnet, occasionally speaking in somewhat unintelligible mumbles. She is shown to be very hot-headed, and has a very short temper. Ruby is very dramatic as well, even referring to herself as an "eternal flame". Ruby also places much value in trust and fusion, being absolutely outraged with Pearl when she learned she was tricked into fusing into Sardonyx and angered at the revelation of Peridot's experiments.

Abilities

Ruby possesses standard Gem abilities, bubbling, shape-shifting, fusion, regeneration, agelessness, and superhuman strength/durability. Ruby seems to possess a higher degree of strength than most Gems, as she was able to shake the walls of her prison with a single punch, lift Sapphire with little effort in "Jail Break", and flip a diner booth table with relative ease in "Keystone Motel".

Fusions

  • When fused with other Rubies, they make a bigger Ruby.

Unique Abilities 

  • Thermokenisis: Ruby is able to increase her core temperature. This is shown in "Keystone Motel", when her body gets so hot that it begins burning the carpet of the motel room, and when she boils the pool to nothing but steam in a very short amount of time. It is also shown to relate to Ruby's temper because when she gets furious, she increases her temperature subconsciously.
