The Girl Genius Universe

Only one crossover with another comics universe so far, but many with assorted webcomics (unfortunately beyond the scope of this site). Also, although this page lists only reprinted editions, the webcomic itself continues weekly at Girl Genius Online.

Includes a story featuring the Heterodyne Boys, ancestors of the Girl Genius herself. Munden’s Bar is a spinoff from the main GrimJack title, and thus, a crossover with the GrimJack Universe.

If DC ever collect Phil’s awesome Stanley and his Monster series, that would fit in right here too.
