In 2005, Liefeld announced that Joe Casey would be re-assembling and re-scripting the original "Youngblood" mini-series into a more coherent and sophisticated story to be titled "Maximum Youngblood". On July 12, 2007, it was announced that Liefeld would return to Image Comics to publish a collected "definitive version" of "Maximum Youngblood" with a new ending written by Joe Casey, illustrated by Liefeld himself. This was followed in January 2008 by a new ongoing series ("Youngblood" Volume 4) written by Casey and illustrated by Derec Donovan, with covers by Liefeld. Liefeld was slated to begin writing and art duties on Youngblood beginning in May 2009. No new issues have come out since then, with "Youngblood" Volume 4 ending with only nine issues.
