The Venomari are a Tribe of Serpentine whose Venom causes hallucinations, making their victims see their worst fears. The Tribe was once banished to the Venomari Tomb within the Toxic Bogs of the Ninjago Realm after the Serpentine War. Acidicus was the General of the Venomari, one of the five Serpentine Tribes that united under the command of Pythor P. Chumsworth. The Venomari and other Serpentine Tribes assisted in locating the Four Fangblades, which were needed to free the Great Devourer. Following the Serpentine's second long-term imprisonment within the Tomb of the Stone Army, the Venomari, reformed. The Serpentine built a peaceful society and reached peace with the humans of Ninjago.
