Coal

"Coal" is one of the four main protagonists in Life Reborn.

She is the fusion of Ruby and Sapphire, and is considered the current, de-facto leader of the Gems. Along with the rest of the team, Coal is one of the last surviving Gems on Earth who joined the Gems in their rebellion against the Gem Homeworld to stop their invasion of the planet. Following the war, Coal helped protect the Earth over the next 5,000 years. After Rose & Quartz were born by Pyrite and Lapis Lazuli and gave up their physical form, Coal began to mentor Saraya and help train her on how to use her powers. Though often stoic and of few words, her most recent exploits have shown her more jovial, outspoken, and emotional.
