Ruby (Doc)

Ruby, nicknamed Doc by Steven, is a Homeworld Gem who made her debut in "Hit the Diamond". She is the leader of the Ruby troops sent by Yellow Diamond to retrieve Jasper. She was last seen floating in space after Steven opened the airlock on the Moon Base, although it is unknown if Navy saved her.

Appearance
Doc's complexion is the same as the Crystal Gem Ruby's in color, but she wears a yellow transparent visor similar to Peridot's and a pair of red shorts, held on by a pair of black suspenders that have two halves of a yellow diamond on the edges. Her gemstone is located on her chest.

Personality
Doc is a natural leader, assertive and professional in her actions. While the others are often distracted, she stays on task. She is the most competent member of the group along with "Eyeball", who is more experienced in Gem history, due to being older than her. She uses strict and commanding language when interacting with the other Rubies, but is very respectful towards Amethyst(who was shape-shifting to appear like Jasper).

Like the other Rubies, Doc is easily fooled by disguises or lies. She also made the error of not including herself in counting the group when she noticed too many Rubies standing about.

Abilities

 * Pyrokinetic Touch: Like the Crystal Gem Ruby, Doc is shown to be able to set things on fire by touching them. This is shown in "Hit the Diamond" when she sets the baseball on fire before throwing it.
 * Photokinesis: In "Back to the Moon", she is shown projecting a red light from her gem as the Gems exit the Roaming Eye. She shares this ability with Garnet, Pearl, Peridot, Eyeball, and the Rutile Twins.
 * Piloting: As shown in "Back to the Moon", she is an expert pilot who is able to fly the Roaming Eye. She shares these skills with Pearl, Peridot, and Navy.

Fusions

 * When fused with multiple Rubies, specifically "Ruby (Eyeball)", "Ruby (Army)", "Ruby (Navy)", and "Ruby (Leggy)", they form a larger Ruby.
