Jake Lockley is shown to be extremely shrewd man who is willing to do anything to accomplish his goals, as seen throughout his various murders in his serving to Khonshu.
Lockley is the most rageful alter of Spector, who is willing to cross nearly all limits in his animalistic rage, who never hesitates to kill anyone to serve his purpose. Lockley possesses a far more brutal disposition than Spector or Grant, as shown when he had killed Alpha and Beta in Cairo when Spector was not in control. His vengeful nature suits perfectly with the likes of Khonshu who uses this alter of Spector to serve his full vengeance on those he views wrong, as shown when he made Lockley kill Arthur Harrow which he complied doing without any inner turmoil. He is fluent in Spanish and it is seemingly his default language. However, he is also shown internally speaking with a Brooklyn accent when inside the Duat and facing Dr. Harrow. The sheer rage in Lockley left him susceptible to manipulations by Khonshu, who manipulated him into being his loyal servant under the offering of immense power and a purpose for serving justice. It also appears as though, Lockley serves as the most loyal servant to Khonshu, who never questions his methods, due to his own brutal nature.
