The Cult of the Kobra is a pseudo-religious criminal organization. Its members, called Kobra Cultists, worship their leader Kobra as a living god. The cultists traditionally wear deep red robes with hoods with attached fang imitating masks hiding their faces.
The Cult of the Kobra took control of Santa Prisca from Bane, and began to combine Bane's Venom drug with the Project Blockbuster formula to create Kobra-Venom, a far more powerful and permanent variant. This drug was tested out on one of their own members, Mammoth, who then easily defeated a Venom-enhanced Bane.
Kobra's plan was to sell Kobra-Venom to Sportsmaster, an operative of the Light. The sale was disrupted by the Team and the Venom factory destroyed. Some Kobra Cultists were captured along with Mammoth and Shimmer, although Kobra himself escaped.
Despite the arrival of Batman, Green Arrow and Flash and their protegés, the ritual went ahead. Shimmer fed some of Jason's blood to a cobra, which grew in size and rampaged through downtown Minneapolis. Kobra cultists kept the protegés at bay while Kobra himself transformed into a half-snake after absorbing his brother in the dagger and then stabbing himself with it. The young heroes nevertheless defeated both the cultists and Kobra, though Kobra himself did not emerge from the dagger after the ritual was undone. They feared he got away.
On Febrary 24,Kobra led his cultists in an attempt to send a transmition to brainwash people into joining the cult. They were stopped by a squad of the Outsiders, and Kobra himself was defeated and captured by Beast Boy.
