Answer
Helms held the Cruiserweight Championship for more than a year, making him the longest reigning champion in the title's history. He defeated Matt Hardy for the title on December 20, 2003, and held it until December 20, 2004, when he lost to Juventud Guerrera. Helms' reign was notable for his successful title defenses against several top Cruiserweight competitors, including Hardy, Rey Mysterio Jr., and Chavo Guerrero Jr.
