The Outsiders by Judd Winick

"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. Calling on established heroes like Jade, as well as newcomes like Shift and Indigo, this new group will find the threats before they become real, no matter what the cost."--
