Ruby is a character from Steven Universe.
She is voiced by Charlyne Yi.
Ruby is a Crystal Gem and who spends most of her time fused with Sapphire, forming Garnet. She represents Garnet's strength and courage, while Sapphire represents Garnet's kindness and compassion. She isn't really conversive, a trait carried onto Garnet.
Order of the Just[]
Both Ruby and Sapphire are members of the Order by default due to being two halves of Garnet. However, they were members of the Order before fusing.
