Willem Reid

William "Willem" Reid, also known as True Willem, or simply Willem, was a renowned special forces operative and mercenary commander. Considered by some as "The Greatest Warrior of the 20th Century," he earned such monikers as "the Legendary Soldier" and "the Legendary Mercenary," feared in combat by both friend and foe as a hero and a madman.

After his time in the CIA, Willem became one of the founding members of The House alongside Eric House, who would come to be his archrival as a result of Eric's questionable ambitions. Having his genetic code used as part of the Les Enfants Terribles project, Willem was the genetic father of Solid Willem, Liquid Willem and Venom Willem.
