Rose Quartz 

Known as the founder and former leader of the Crystal Gems (at least in theory, it could be Pink Diamond). Enthralled by the beauty of Earth, Rose led her friends and allies in a Rebellion against the Gem Homeworld around 5,500 years before the events of the series, successfully driving the invading Homeworld Gems off the planet and saving the life forms inhabiting it. Rose eventually developed a romantic relationship with a human, Greg Universe, before giving up her physical form to give birth to their son, Steven, who inherited her gemstone.

    Abilities:
    

Rose possessed standard Gem abilities, including shapeshifting, weapon-summoning, fusion, bubbling, regeneration, and superhuman strength/durability. As a Quartz Gem, she was created to be a soldier, albeit one with abilities that focused on defense. Noticeably, she was able to effortlessly defeat a fusion of three Rubies in an instant. She was proficient in both combat as well as military command and strategy, being able to lead the Crystal Gems from the front-lines in a successful rebellion against their Homeworld.

• Enhanced Strength: Being a Quartz, Rose had strength fit for a soldier. In "Greg the Babysitter", she destroyed the control panel to a Ferris wheel with a single punch. She was then able to stop the malfunctioning Ferris wheel, and ripped off one of the seats with her bare hands.
• Enhanced Reflexes/Speed: "The Answer" and "Greg the Babysitter" showed that, despite her size, Rose was extremely fast and agile. In the former she destroyed a Ruby fusion quickly and precisely, and in the latter she ripped off a seat of the Ferris wheel leaped and caught a falling Greg.

• Healing: Rose manifested her ability to heal through her tears. Her tears could heal broken Gems/gemstones, and heal other creatures of general injuries. In "Bubbled", Eyeball mentions that she heard rumors about how during the Rebellion, Rose used her healing power to keep her Crystal Gem soldiers in contention with Homeworld's superior forces.
  • Resurrection: In Lars' Head, it is implied that Rose could also resurrect organic beings, giving them special powers in the process, the most notable example being Lion.
• Phytokinesis: Rose had the ability to grow sentient flora that act as her guardians.
• Shield Proficiency: Rose had the ability to summon her shield to protect loved ones.
• Electrical Interference: In "We Need to Talk", Rose appeared to be able to control Greg's radio based upon her emotion. For instance, when she was shocked, the music stopped. However, like her son, it is unknown if she possessed it or if this was for dramatic effect.
• Speed of Descent Regulation: In "Steven Floats", it is revealed that Rose was able to alter her gravity, allowing her to control the speed of her ascent and descent. 

Scaramouche

Known as Scaramouche the Merciless was an android who used to be Aku's number one assassin. His specialty was using his (literally) magical voice to battle his foes.

    Abilities: 

• Enhanced Speed and Agility: Scaramouche was remarkably agile. He was able to leap tall structures in a single bound, quickly dodge Jack's attacks, and massacred an entire village in only a day.
• Musical Telekinesis: Using a "magic" flute, Scaramouche could levitate objects and create golems to fight opponents. When the flute was destroyed, he could continue to levitate objects by scatting, indicating this power comes from his voice and the flute merely amplified his ability, since he only needed to control his sword through his voice. His power depends on his vocal chords, and he becomes defenseless after Jack damages his neck, nullifying the ability.
• Swordsmanship: Scaramouche was a master sword fighter, easily holding his own against even the experienced Jack, and carries multiple blades on his person, including a heavy scimitar and a special "tuning sword" that destroys objects on contact.
• Multi-linguist: Scaramouche appeared to understand French, as he taunts Jack with au revoir which is goodbye in the language. However, he sarcastically remarks it's French for "You're dead, babe."
• Observant Analyst: Scaramouche was shown to be very observant, as he's able to point out that Jack has changed his appearance a lot and even noticed that the samurai didn't have his sword anymore.
• Durability: Despite being cleaved and beheaded by Jack, Scaramouche survived his encounter and was able to continue functioning despite no longer having a body, a feat that most other robots can't do. Although this is most likely due to the fact that Jack could not eradicate all of Aku's essence within him due to killing him with something other than his sword.
• Body-Takeover: As a head, Scaramouche had the ability to take over the body of any organism as long as his head is placed on the neck area of the body.
• Maneuverability: Scaramouche was able to travel long distances even if he only has just his head and part of his neck, simply hopping around on the latter.
• Buoyancy: Despite being made of metal, Scaramouche's head could float in water without sinking.
• Waterproof: It was shown that his electronic circuits are waterproof, since he could not be electrocuted or short-circuit while floating in water, despite the exposed circuitry in his neck.
