Curt was a high-profile businessman who invested into Muirfield when it was originally started 30 years before. He also volunteered to be an experiment and have the serum injected into him, presumably to get even with rivals. However, the strain he was injected with didn't immediately affect him; Muirfield thought it didn't work. However, it eventually mutated, and Windsor transformed, killing off his rivals viciously. He secluded himself and his daughter, Tori, by barricading themselves within their home and surrounding them with bodyguards, preventing them from being exposed or from anyone trying to come after him and Tori.
