Thomas Koppelthorn

Dr. Thomas Koppelthorn is Vice President of SaintLogic. Koppelthorn later plotted revenge against Snake, the man who he believed was responsible for the murder of his wife, Lucinda. After the death of his wife, Koppelthorn scanned her nerve junctions, extracting her character and memories. It was his intention to revive his own wife by inseminating her consciousness into another body, using nano-chip expansions - a system capable of transplanting one's abilities and experiences into another. In order to find a suitable host, Koppelthorn purchased dozens of young children from numerous criminal groups in Africa and South America. Eventually, Koppelthorn discovered the ideal body - that of a young girl named Lucy. With the experiment nearing completion, Koppelthorn then began to enact his revenge. Seizing control of the "Chaioth Ha Kadosh" Metal Gear, Koppelthorn demanded that those responsible for the Praulia Massacre (and subsequently, the death of his wife) should be handed over to him. If his demands were not met, Koppelthorn threatened to launch a nuclear attack using the "Chaioth Ha Kadosh".

In the Snake Tales story External Gazer, he is the creator of the Koppelthorn Engine, designed as part of a grid computing system spread between all parallel universes
