The Capricorn Vertex (カプリコーン・バーテックス) is an enemy of humanity, and the fifth Vertex the Hero Club encounters. It is based after the constellation Capricorn the Horned-Goat.
Its color palette is white a blackish hue and gray. Capricorn has four horned like structures for its legs. They are connected to the main body which almost looks like a person sitting on it.
It was first introduced in Episode three of Yuki Yuna and was soon defeated by Miyoshi Karin.
The horns which are a notable feature are capable of being used as drills. They have been known to be used twice, the first time being against Nogi Wakaba when she was trapped in a bubble created by the Aquarius Vertex during the initial years of the vertex attacks, as well as when fighting against the first Hero team.
In Yuki Yuna, during the Sealing Ritual, the Soul emits a gas to delay its time being sealed.
