The United Clan of ROBLOX (UCR) is a well known superclan on ROBLOX and one of the original "big three" superclans, which also includes the Roblox Assault Team (RAT) and First Encounter Assault Recon (FEAR). It is run on the principles of honor, dedication, and respect. Despite the fact that it is a war group, UCR is considered one of the most pacifistic clans on ROBLOX. The United Clan of ROBLOX was founded in the summer of 2009 by Kinglime to compete against and ultimately destroy the rival clan The X-101st Legion. It is known to be the first warclan ever made as well as the 18th ever made (hence its group ID of 18.)
