Wesley has a short blonde hair with full-opened fringe and green eyes.
Despite he wearing no upper underwear, Wesley wears a black jacket with blue colors addition on top (including his collar), a light khaki pants and brown shoes. Wesley also wears a necklace with bone as a pendant.
Wesley joined the V.S.S.E. at the same time as Alan Dunaway, He was a proven marksman of the agency, He's a friendly, quiet, smart, reserved, and cheerful-looking man, and he currently holds a doctorate degree in engineering. Wesley is best known for his own unflappability in extreme situations, where he can make snap decisions strategically. Wesley is also a natural animal-lover/caretaker. Because he and Alan get along extremely well, they are different from other agents/teams.
Although Alan and Wesley were V.S.S.E. agents only for 4 years, they were already far and away trustworthy, as they were qualified to act as officers in a simulation fight for newer agents based on the Astigos Island Crisis. Both served as the final test newer agents (up until the Hamlin Battalion incident) must surpass as a part of the undeniably high amount of battery and aptitude of training agents must undergo before becoming fully-pledged V.S.S.E. agents.
While the V.S.S.E. agents helped Alicia, he was the one who always fully-attentioned on her life. This is revealed in a cutscene which shows Daniel Winston clubbed by Giorgio Zott, then Wesley held her and told her to rescue Daniel, this indicates that he has feelings for Alicia.
His personality is more mature than Alan.
Wesley's haircut is similar like one of American boyband Backstreet Boys member Nick Carter.
His name is later shared by Wesley Gibson, the protagonist of the 2008 film Wanted.
