Vertex

Vertex are a race of malevolent entities set on destroying humanity. They are the primary antagonists of the anime Yuki Yuna is a Hero and its following video game and manga spin-offs.

Biography
Vertex were created to pass down judgement upon humanity. The Vertex took these objectives to extreme measures and destroyed everything in their path. They succeeded in destroying a majority of the world, except the Shikoku island of Japan, which is under protection by the Shinju, the Divine Tree that protects the rest of the planet under its realm of Jukai. The Vertex attempt to break through the Jukai and reach the Shinju to destroy the last trace of humanity, although the Taisha, a cult worshiping the Shinju, used a counterattack in the form of Heroes, a group of girls gifted with magical powers from the Shinju in hope to defeat the Vertex and restore whatever remains of the planet and possible universe from the force of the Vertex.

Each Vertex is named after a constellation sign in the Zodiac.

Stardust
Stardusts are the smallest unit of the Vertex. Although not very strong and durable, in which a single hit from any force is strong enough to kill one, multiple Stardusts move in massive hoards in attempt to outnumber their enemies. When multiple Stardusts combine together, they are able to produce one of the twelve evolved Vertex.

Virgo
The Virgin, Virgo is the first Vertex the Hero Club go against. It can shoot out explosive pods out of its tail-like abdomen and use its ribbon-like appendages to slap or slam Heroes out of the sky.

Libra
The Scale, Libra can swing itself around to create unstable winds and miniature tornadoes.

Scorpio
The Scorpion, Scorpio is one of the stronger known Vertex. This is due to the powerful venom it carries within its tail, in which if someone is stung, they will experience extreme swelling to their bodies before bleeding to death. Out of all the Vertex, Scorpio has the highest kill rate out of all the Heroes, killing three notable characters: Tamako and Anzu in Nogi Wakaba and assisted in the death of Gin in Washio Sumi.

Sagittarius
The Archer, Sagittarius's appearance includes two mouths, one on top of the other. The smaller head on the bottom fires a barrage of small-needle like projectiles while the larger head on top fires a singular large projectile that explodes on contact. These projectiles can also impale other Vertex, healing their wounds.

Capricorn
The Sea Goat, Capricorn uses its legs and abdomen as drills.

Aquarius
The Water Bearer, Aquarius manifests the element of water to drown its targets, ranging from balls of water to beams of high pressure water. According to Gin, the water Aquarius produces has an Oolong-like flavor.

Pisces
The Fish, Pisces can dig through solid ground. The Shinju cannot detect Pisces while it is underground in the Jukai, giving it an advantage to maneuver around the battlefield unnoticed.

Aries
The Ram, Aries is not only fast, but is also able to duplicate itself when it is damaged. However, only the duplication with the core in its body is the true Aries while the rest are only imitations.

Taurus
The Bull, Taurus uses a bell on its back to produce a powerful sound, loud enough to immobilize every Hero in its range. This sound does not effect Vertex, providing a distraction for Vertex other than Taurus to make their way to the Shinju, that is should Taurus continue to ring its bell.

Gemini
The Twins, Gemini is the only member of the Vertex who does not come as a singular unit, but two. Gemini is the smallest member of the evolved Vertex, only taking a few Starbits to be formed. Despite its position as the weakest of the Vertex, Gemini makes up for it with extreme agility, able to dodge any ranged attack effortlessly. Because of this, it tends to ignore initiating combat and instead rush towards the Shinju while the Heroes are distracted by the other Vertex.

Cancer
The Crab, Cancer is surrounded by six giant plates used to block or reflect obstacles. This works as an advantage when paired with ranged shooting Vertex, such as Virgo and Sagittarius, as it is able to bounce and reflect their shots in angles they cannot do themselves.

Leo
The Lion, Leo is the largest and strongest member of the Vertex. Its element is solar energy, which it can shoot out in beams, or even engulf its entire body into a massive star-like fireball. Although very powerful, it tends to stay in the background while the rest of the Vertex attack in the front line, leaving speculation that Leo acts as a captain or strategist for the Vertex, ordering and monitoring each of their commands. However, this strategy actually works as a last resort should the Vertex at front be wounded or defeated, allowing Leo to absorb the remaining Vertex and form into Leo Starcluster.

Leo Starcluster
When Leo or another Vertex is damaged, it is able to combine itself alongside other Vertex in the area to form a fusion called Leo Starcluster. In its Starcluster form, Leo is able to perform every ability used by itself and by the other Vertex it absorbed, only much more powerful variations.
