Kathryn Immonen

January 2011 saw the release of Marvel Comics new four part mini-series Wolverine and Jubilee, with artist Phil Noto. In 2012, she took over the Journey into Mystery title with issue #646, transitioning from Loki to Sif as the main character.

In May 2009, Immonen became writer for the Marvel Comics' award-winning series, Runaways with artist Sara Pichelli.

Kathryn and Stuart Immonen have been creating various webcomics alongside their print work for Marvel Comics. Their first webcomic was Never as Bad as You Think, which was published by Boom! Studios in December 2008. The webcomic was followed by Moving Pictures, which saw a print publication by Top Shelf Productions in April 2010. The latter webcomic took on a darker tone than the humorous Never as Bad as You Think, taking place in 1940s France during World War II and starring a Nazi protagonist. The A.V. Club described Moving Pictures as "illustrative of what a major writing talent Immonen really is."
