Gill's name might come from the Hebrew Gilead, meaning "eternal joy". His personality comes from various Judeo-Christian sources. Gill is physically modeled after the Greek Gods of antiquity. His flowing long blond hair is tied in a very low ponytail adorned with a white clip. His battle costume resembles the outfit worn by the Roman Empire a gold sleeveless armor with a matching helmet, gauntlets and leg guards, a brown Roman skirt that reaches below the knee and a long red cape. Gill is also seen wearing a white robe in his own character story. This outfit later became his first alternate costume.

In Street Fighter V, during Kolin's character story, Gill wears only a white robe-like cloak with the left side being sleeveless. In 3rd Strike, he wears a light brown and red hooded long cloak with a long blue green robe and matching brown sandals. In his pre-fight intro in New Generation and 2nd Impact, Gill wears a long gray robe. In the UDON comics, before he changed into his signature skin and eye colors, Gill's skin was tan and he had dark gray eyes. In 3rd Strike, a special glow has been programmed to constantly render his sprite in both positive and negative coloration, further showing off the CPS-3 board's impressive graphical power. The sprite of Gill's secretary, Kolin, has an intentionally asymmetrical haircut, so, like Gill, she appears graphically impressive when rotating from facing one direction to another, instead of being a mirrored sprite. Additionally, Gill was designed wearing a loin cloth to show off as much of his red and blue hues as possible. The black and white palette is used often as a secondary color. It was later decided to color him red and blue, to better show off the game's graphical power. Originally, Gill was to be colored black and white, and utilize powers over light and darkness. In previous 2D Street Fighter games, details such as Sagat's eye-patch would switch sides depending on which way the character was facing. Gill's asymmetrical color scheme was a device for Capcom to display the graphical power of the CPS-3 board. In keeping with that theme, Gill fights completely unclothed except for a white thong around his hips. He bears a distinct and intentional resemblance to a Greek God. Gill's appearance is characterized by his half red and half blue muscular body and flowing blonde hair. 3.4 Prologue - 'The Emperor Doesn't Look Back'.
