Thomas Davidson (Earth-616)

Thomas Davidson along with other agents Vasili Dassaiev, John Garrett, Shoji Soma, Cornelius van Lunt, Baron Strucker, Dum Dum Dugan, Nick Fury, Jake Fury, Daniel Whitehall, and Viktor Uvarov were called by Leonardo Da Vinci alias Aries to form the Great Wheel of Zodiac. Each member was assigned a codename from the Zodiac Calendar, Thomas was known as Virgo. The group consisted of the best covert intelligence agents from around the globe. After only a few key missions for Da Vinci, would provide them resources that would be of great value to their own separate agendas.^[1]

Each mission involved acquiring advanced technology from around the world. Thomas executed a mission with the Fury brothers to Chapel at Chateau D'Amboise in France, where they found the technology that would later be reverse engineered into Life-Model Decoy. Jake unwisely got too close and activated it. The technology latched onto him and Davidson, creating Life-Model Decoys of them both. Nick decided to keep this a secret.^[1]

The Great Wheel later fell apart due to the betrayal of Vasili Dassaiev and Viktor Uvarov. The broken Wheel led to the creations of S.H.I.E.L.D., Hydra, Leviathan, and the Zodiac Cartel.^[1]

While Davison and his Life Model Decoy were working for SHIELD as programmers, the LMD went mad, believed itself to be Davison, and betrayed SHIELD to Hydra. The real Davison, still in SHIELD, was able to use Hydra's efforts to subvert and replicate his systems to hack back into Hydra's systems, an espionage coup which was of great use to Nick Fury years later.^[2]
