What Happened To Everyone Who Joined The Guardians Of The Galaxy?

Jack joined up with the team after he was made a fugitive on Earth thanks to the events of Civil War and had his spine broken, choosing to pay back the debt he owed them for fixing the latter of those two problems rather than own up to the former on Earth.

Despite the truly hilarious hair and the lack of any powers, Jack proved himself a capable Guardian through sheer cunning and a bravery that often bordered on suicidal. This of course, makes his end all the more tragic.

Oh sure if a writer wants him back, he'll come back, but given Flag's lacking popularity, that might be a while. So the moment where Cap turns to the dark side in the setup to Secret Empire and throws Jack Flag out a window to his doom is the last we're going to see of him for some time.
