Known as "Baltimore's blasphemous bad boy",[2] the character is unusual in the underground genre for being "shared" by a number of different creators, appearing in stories by (among others) Jay Lynch, Art Spiegelman, Skip Williamson, and Robert Crumb.

In WILD's peak (the years 1961–1963) it featured cartoons by the likes of Jay Lynch, Art Spiegelman, and Skip Williamson, who all later went on to be significant contributors to the underground comix movement of the late 1960s and early 1970s.

The character finally appeared in his own title in Don Dohler's ProJunior (Kitchen Sink Press, October 1971), which featured contributions from 22 underground cartoonists, including Lynch, Crumb, Spiegelman, Williamson, S. Clay Wilson, Evert Geradts, Jay Kinney, Justin Green, Jim Mitchell, Trina Robbins, Denis Kitchen, Bruce Walthers, Joel Beck, Bill Griffith—and his creator, Don Dohler.

ProJunior's final appearances were in Lynch and illustrator Gary Whitney's Phoebe & the Pigeon People comic strip, which were first published in the late 1970s.

When he began appearing in the comix he sported a leopard skin leotard,[5] and under Crumb's direction dropped his cartooning aspirations and became more of a rabble-rouser and weekend revolutionary.
