Blue Diamond

==Summary==
Blue Diamond is one of the Four Diamonds that rule Homeworld, and is usually accompanied by her servant Blue Pearl. Like her fellow Diamonds, she is tall, intimidating and implied to be immensely powerful. She was the supervisor of the Earth Colonization project before the project was abandoned due to the Crystal Gems' rebellion, taking the demise of Pink Diamond hard as she secretly made regular visits to the site of her fellow Diamond's death. Blue Diamond is also the cause of Garnet joining the Crystal Gems, having condemned the fusion when first formed by accident.
==Powers and Stats==
Tier: Likely 
Name: Blue Diamond
Origin: Steven Universe
Gender: Genderless, but regarded as female
Age: 20,000 years old ()
Classification: Gem, Diamond, Matriarch of Homeworld
Powers and Abilities: Superhuman Physical Characteristics, Gem Physiology (Grants Regeneration [High-Mid], Immortality [Types 1 and 3], Shapeshifting, Size Manipulation, Body Control, Biological Manipulation, Fusionism, Self-Sustenance [Types 1, 2, and 3], Automatic-adjustment to different strengths of gravity, Pocket Reality Manipulation [All Gems have a pocket dimension of infinite size contained within their gemstone], Sealing and BFR [Via Bubbles]), Large Size (Type 1), Empathic Manipulation (Can project her emotions onto others, has shown the ability to do so with both Sadness and Joy), Aura (Allows her to detect and harm entities on the astral plane as well as seemingly increasing her physical attack power as she used it to break Lapis Lazuli's water-chains), Danmaku, Energy Projection, Corruption (When combined with White and Yellow she is able to corrupt an entire planet's worth of Gems), Weather Manipulation (Can create clouds that make Gems happy when they make contact with them), Pseudo/Reliant-Flight via riding on the clouds she creates. Resistance to Empathic Manipulation, Telepathy (Steven struggled to get near her in his Astral Projection form due to their aura), and Gem Destabilization (Resisted Yellow's electricity, which destabilizes a gem's form)
Attack Potency: Likely Moon level+ (Alongside the other three Diamonds, was capable of splitting apart Homeworld just by emerging. Exchanged blows with Yellow Diamond. It's implied that the Diamonds are much more powerful by regular Gems by an unknown degree. Additionally, WoG implies that Diamonds have never been "poofed" before, which may imply that no known Gem has matched their might)
Speed: At least Relativistic, likely higher reaction and combat speed (Should be far superior in speed to the Crystal Gems by somewhat scaling to Pink State Steven), Massively FTL+ Attack Speed (Capable of attacking this fast)
Lifting Strength: At least Class G (Comparable to Yellow Diamond)
Striking Strength: Likely Moon level+
Durability: Likely Moon level+ (A combined attack from Steven, Garnet, Amethyst, Pearl, Bismuth, Peridot, Lapis Lazuli, and Lion did nothing but annoy her. Took a sustained direct attack from Yellow for several seconds without poofing)
Stamina: Infinite, as long as her gem isn't damaged nor destroyed
Range: Extended Melee Range by virtue of size; Tens of Meters via Empathic Manipulation (her emotions reached the beach house); Intergalactic with ranged attacks
Standard Equipment: Blue's Warship, Palanquin
Intelligence: Likely Gifted, as she is the ruling Matriarch of Homeworld and oversaw the Earth Colonization project
Weaknesses: Emotionally sensitive, Sufficient damage to her physical form can revert her back to her vulnerable gem form which can be broken and destroyed. Her powers are less effective on anything that has experienced worse grief than her (although Lapis Lazuli was affected by it, it didn’t take much of a toll on her) and are seemingly ineffective on non-gem life-forms (Lion and Connie were unaffected by her aura).
Notable Attacks/Techniques: 
*Aura Projection: The Diamonds can project an aura around them that they can control, they can either radiate it from their entire bodies or emit it from specific parts of their bodies, usually their hands. Blue's aura is blue and has water-like properties. Though intangible, Blue was able to break Lapis' water chains from her hands upon coating her hands with her aura. She can use this as an offensive ability in both the physical and mental plane, as seen when she was able to focus her aura and attack Steven as he was projecting. 
**Radiated Pathokinesis: Blue Diamond can engulf a large area with her aura which induces sorrow to anyone exposed to it. The induction is powerful enough to cause Gems exposed to the aura to break down and cry immediately unprovoked, even affecting Yellow Diamond to a small degree. When she unleashed her grief over Pink Diamond's death, she instantly rendered the Crystal Gems unable to fight. The aura is also potent enough to split all but the most stable Gem fusions that get caught in it apart, as Alexandrite came undone as soon as she was affected by the aura, while Garnet remained whole. The level of resistance to the ability varies. Humans and animals are apparently not affected, as demonstrated by Connie and Lion during Yellow and Blue's attack on Earth. Gems who feel that they have endured emotional trauma worse than the feelings induced by the aura can resist it almost completely, as Lapis Lazuli barely shed a tear upon being hit by the aura.
**Concussive Blast: Blue Diamond is able to concentrate her aura at a single point outside her body to launch long range energy blasts at her opponents.
*Energy Projection: She is shown to have some form of energy projection power that she uses for battle. The energy can be molded into different projectiles, from spheres to a hail of lasers, or combinations thereof.
