Weapon Masters of Techadon are a weapons and technology R&D group from Techadon.
One of them first appeared in Inspector 13, but they were mentioned in earlier episodes. They are a weapons group that creates, supplies and sells weapons to anyone who can afford them their prices. They are incredibly anti-social and never leave their homeworld. No one has ever seen one of them and lived. It is even impossible to encounter the Weapon Masters when buying their products, as when Vulkanus bought Techadon battle robots from them, they simply sent a remote unit to construct them.
They have powerful technology and ships, with some close to Galvan inventions, as Weapons Master 13 was able to hack through the Ultimatrix's three firewalls very quickly. They have advanced suits filled with voice-activated technology and weapons that can deploy almost anything for various scenarios. They take their products very seriously and inspect events in which many of them fail, which was Weapon Master 13's original purpose for searching for the Ultimatrix.
The Weapon Masters are cold and calculating and have no concern with what those who buy their products do with them. They have no problem with killing or kidnapping to reach their means. Weapons Master 13 wished to study Gwen's Anodite abilities to improve Techadon defense systems. He also wanted to use Kevin's Osmosian powers to create raw materials for Techadon forges as punishment for wrecking the factory. While some of their products, such as the Techadon Factory, are custom jobs, others, such as individual Techadon robots, can be commonly bought "off the shelf" and mass-produced.
Unlike the more benevolent Galvan (who usually develop technologies that benefit others peacefully), the Weapon Masters study any and all advanced technological feats in order to transform them into weapons of warfare to auction off to the highest of bidders (not caring what their weapons are going to be used for exactly as it's no longer their issue anymore).
Due to their technological developments, the Weapon Masters have managed to seclude themselves in every sense of the word by a massive defense system (Gwen was going to be dissected and studied in order to advance their technology against Anodites), as well as creating the most efficient factories and ships made from materials that can self-replicate and adapt to anything (This material is unable to be absorbed by Osmosians or phased through by Necrofriggians like Big Chill, but is easily torn apart and digested by Gourmands).
- According to Kevin, the Weapon Masters of Techadon never leave their home planet.
- According to Geoffrey Thorne:
- There are at least thirteen Weapon Masters of Techadon, including Techadon Weapon Master Number 13.
