Michael Krahulik (born September 25, 1977) is an American artist for the webcomic Penny Arcade and co-founder with Jerry Holkins of Child's Play, a charity that organizes toy drives for children's hospitals. He goes by the online moniker "Jonathan Gabriel" or "Gabe". Krahulik does not physically resemble his comic strip counterpart, as the character was not originally meant to represent him.
