General Vaughton was a General in the Vektan Army who commanded respect and trust from his troops while he was leading the ISA ground forces on Vekta in defense of the Helghast invasion. During which, he ordered Templar to meet up with Shadow Marshall Luger and Rico in mission to rescue Colonel Gregor Hakha. Before Templar went on the rescue mission he retrieved the security key for General Vaughton who then went up to the SD Platform to reactivate the platforms weapon systems. Shortly afterwards, he discovered that the SD Platform was under the control of the Helghast and he was killed by a Helghast trooper on the orders of the traitor General Adams.
Vaughton was a friend of Jan Templar's father Dirk Templar who was an ISA soldier. However, when Dirk Templar was killed during the Extrasolar War, Vaughton felt responsible to look after young Jan Templar who was his godson. Training him with all the required military skills to exceed his father's potential, Templar matured into a deeply-promising soldier, far more intelligent tactically and morally unwavering than other ISA soldiers. This forged a strong father-son bond between the pair illustrated during the events of Killzone where Vaughton entrusted Templar to guide a small unit through Vekta, triggering a famous fight from Templar. The latter also showed how dearly he loved and respected Vaughton, his early tenacity and high-energy nature sapped and deflated in the aftermath of Vaughton's death where he seeks to avenge him and simply honor Vaughton's name.
- Vaughton bears a striking resemblance to Supreme Allied Commander Dwight D. Eisenhower.
