Sometime between 20 he and his subsidiary CryNet developed the Nanosuit 2.0. During the war, it was realised that the Nanosuit 1.0 was actually more potent than first thought, as it developed a symbiotic bond with its user and even managed to communicate with the nanosystems possessed by the Ceph. He was in command of Prophet and presumably guided him around the island. As he required to test the Nanosuit's ability to combat and circumvent the currently dormant Ceph threat, Hargreave thus orchestrated the events in Lingshan in 2020. His research and development eventually culminated in the Nanosuit 1.0 which he considered a prototype and penultimate design for his grand masterpiece (the Nanosuit 2.0). He soon devoted his life to making anti-alien technology by reverse engineering the Ceph tech he found a century ago in Tunguska. Despite his immobility and vegetative state, Hargreave is able to communicate with others through a proxy screen, which portrays a younger version of himself, sitting on an armchair.

He managed to continue his life through the use of the stolen Ceph technology and actually resides in a stasis tube as he is too old to be mobile.

Later in his life (presumably after World War II) he established CryNet as a subsidiary of Hargreave-Rasch. Hargreave is only alive as of 2023 because of his efforts in Tunguska where he stole and later reverse-engineered advanced Ceph technology and along with Karl Rasch established the Hargreave-Rasch Biomedical Research Centre. Hargreave also comes into possession of alien technology and knowledge of the threat the Ceph pose to human civilization. Hargreave was able to carry the other two across the Siberian wastes in an apparently superhuman demonstration of strength and endurance before being rescued by members of the British expeditionary force operating from Vladivostok. The events transpired in Tunguska led to the discovery of the Ceph and through unknown circumstances left the expedition except for Hargreave, Rasch, and Gould dead. In 1919, Hargreave went on a private expedition to investigate the site of the Tunguska event in 1908 with his colleagues Karl Rasch and Walter Gould.

His deep distrust of government and governmental power, common to many self-made Americans of the time, has only been intensified by his extreme longevity. Experience has taught him that success invariably lies in seizing latent opportunities for the future before others spot them. His strong entrepreneurial spirit enabled him to support his family and ultimately made him one of the richest, most powerful men on the planet. Born to middle class parents in Ohio in 1896, Hargreave enjoyed a relatively gentle early life later blighted by his father's bankruptcy.
