John F. ("Johnny") Ryan IV (born November 30, 1970 in Boston, Massachusetts) is an American alternative comics creator. He is best known for Angry Youth Comix, a comic book published by Fantagraphics, and for "Blecky Yuckerella", a comic strip which originated in the alternative newspaper the Portland Mercury and now appears on Ryan's website. He is also known for Pig Goat Banana Cricket, a series which was made jointly with Dave Cooper that Nickelodeon picked up. In a throwback to the days of underground comix, Ryan's oeuvre is generally an attempt to be as shocking and politically incorrect as possible.
As a writer of the series, he is also known for the voices of Brando, Alexander Hamilton, Pilgrim Ghost, Paul, Steve, Hot Harry, Shoe Pile, Hyena, Lady Shoe Pile and TGI Freddy.
