Ruby (Steven Universe)

Ruby is a Crystal Gem that appears in Steven Universe. She is one of the Gems that fuse into Garnet along with her love interest Sapphire.

Appearance/Personality
Ruby is a small maroon-colored gem with puffy black hair and maroon-colored skin. She wears a red tank-top with mahogany shorts, red boots, and a red bandanna tied on her hair. She has a ruby gem embedded on her left palm. Her gem weapon is a boxing glove as shown in

Ruby is very courageous and stubborn, but does have a soft spot for her crush Sapphire. If angered, Ruby can thermoregulate her body temperature and cause her entire body to heat up, so much so that it can even douse out pool water in seconds. She states herself that she is an "eternal flame".

History
Ruby debuts in the episode "Jail Break" where she and Sapphire were tossed into a cell. Steven later frees her and she hears Sapphire's singing and runs to find her. They come accross Lapis Lazuli whom Ruby does not trust. After Lapis refuses to go with them, Steven sets Sapphire free and she reunites with Ruby as they kiss, twirl around, and happily fuse back into Garnet.

In "Keystone Motel", an angered Garnet unfuses into Ruby and Sapphire as Ruby is still angered at Pearl for tricking her and not taking fusion seriously. She stomps out of the motel to literally "let out some steam" as she is still angered at Pearl's actions. When she marches into the water via Stven's encouragement to cool off in the pool, she boils the pool water and causes Steven to go back to the motel. Later on at "The Best Diner Ever", Ruby gets into a huge temper tantrum in the restaurant and destroys the dining table. While getting into an argument with Sapphire, Steven has had enough and stomps out of the restaurant. A guilty Ruby and Sapphire apologise to Steven for their actions and make up with each other, thus fusing back into Garnet.
