Created by writer Peter David and artist David Lopez, the book ran for 20 issues between 2003 and 2005. The omnibus edition marks the first time that the final six issues have been collected in any format since their original printing.
"Thanks to some graciousness on DC Comics' part - namely that of Paul Levitz and a few others, we're able to now collect the entirety of Peter David and David Lopez's 20-issue Fallen Angel series," wrote IDW editor-in-chief Chris Ryall.
"This is the original run, the final six issues of which have never been collected in any format since their original comic book release. We're collecting them all in our Omnibus format, so you'll get the entire run in one volume."
Fallen Angel Omnibus arrives in stores in May.
