The Outsiders by Judd Winick Book One — DC Comics

The Justice League is a bunch of pushovers. The Teen Titans are just kids. When the DC Universe calls for a more...aggressive approach, they call Nightwing, Arsenal and company: the Outsiders. A renegade Superman Robot goes on the rampage, and a long-standing member of the Teen Titans dies. Stricken with grief, old allies Nightwing and Arsenal decide that enough is enough: a more proactive approach to justice isn't just needed -- it's necessary. This title collects TITANS/YOUNG JUSTICE: GRADUATION DAY #1-3, TEEN TITANS/OUTSIDERS SECRET FILES #1 and OUTSIDERS #1-7.
