Michael Krahulik 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.

Penny Arcade is a webcomic focused on video games and video game culture, written by Jerry Holkins and illustrated by Mike Krahulik. The comic debuted in 1998 on the website loonygames.com. Since then, Holkins and Krahulik have established their own site, which is typically updated with a new comic strip each Monday, Wednesday, and Friday. The comics are accompanied by regular updates on the site's blog.
