"Mike Krahulik (born September 25, 1977) is the artist who draws the popular webcomic Penny Arcade. He goes by the online moniker "Jon(athan) Gabriel" or "Gabe". He does not physically resemble his comic strip counterpart, as the character was not originally meant to represent him.
Krahulik credits cartoonist Stephen Silver as a major influence on his drawing style. His style has become dramatically more stylized since he began drawing Penny Arcade in 1998.
Krahulik has done promotional comics for Tom Clancy's Rainbow Six and many other video games. He also provided the illustrations for the cover of Agent to the Stars by John Scalzi. In his early career he contributed artwork to the Daily Victim, a regular feature that used to run on GameSpy.com, totaling more than 300 illustrations."
