The Weaponeers are a group of arms dealers and weapons experts who use their superior technology to terrorize people and countries.

They first encountered the X-Treme Sanctions Executive when they assaulted the citizens of the Central Saharan Republic, claiming the land and people under the reign of Achmed Al-Khalad. Most of them, including their sergeant, were captured, but some were on a plane with the captain when the team fled, teleporting from Cannonball's attacks.

They were later hired by the Hellfire Club led by Sat-Yr-Nin, who wanted to conquer Genosha by using Zanzibar as an advance base. They were confronted by the Genoshan Excalibur, Mutantes sans Frontières, and one of its associates: Jono Baraka, president of Tanzania and also known as the mutant superhero "Askari the Spear". The Weaponeers ended up double-crossing Viper and Sat-Yr-Nin. In retaliation, Viper shot Scimitar in the back, killing him.^[1]

During an attempt to take control of the nation of Zanzibar,^[2] they were confronted to the X-Men Psylocke, Bishop, Marvel Girl, and Storm.

The X-Men were close to victory when the Scarlet Witch warped the reality into a mutant-dominated Earth.
