The Scorpion Vertex (スコーピオン・バーテックス, Sukōpion Bātekksu), is an enemy of humanity, and the fourth Vertex the Hero Club encounters. It is based on the constellation Scorpio, The Scorpion, and is one of the most powerful Vertex in existence.
A yellow face-mantle above a carried orb containing a pulsating bubble. Sports a long tail comprised of multiple spheres, tipped with a powerful stinger. This stinger contains a venom so potent that it can cause a Hero to experience immense swelling from even a light scratch or glancing blow, like in the case of Iyojima Anzu.
A sting so powerful that it can break a hero out of Mankai with a single strike. Lashing, blunt tail attacks meant to shove/disrupt.
This Vertex serves as the front-line for the trio of the Scoripio, Cancer, and Sagittarius Vertexes. Its powerful single-target attacks and disruption make it a force to be reckoned with, but when united in its trio, it is nearly impossible to defeat.
Works in tandem with the Cancer Vertex and the Sagittarius Vertex in order to destroy the world.
- This Vertex was able to destroy Miyoshi Karin's Mankai with a single sting.
- This Vertex's soul is located inside of the orb it carries; its interference tactic is multiplication. Upon emerging, this soul channels briefly while rotating and emitting light, before splitting into a cluster of at least thirteen identical copies of itself; Itsuki Inobuzaki's wires made short work of it: "There may be many of you, but I'll get you all at once!"
