Ruby mainly embodies Garnet's strength and courage, while Sapphire embodies Garnet's cool nature and calm under pressure. Ruby is extremely passionate and emotional. She is known to have a short temper and violent ways of exhibiting her anger; this is best seen in "Keystone Motel", when she is infuriated to the point of using her thermokinesis and boiled the motel pool, even summoning her weapon at The Best Diner in the World.
