"Waterproof Robotman" from Doom Patrol vol.4 #3 (DC, 2004) by John Byrne and Doug Hazlewood
John Byrne obviously has a love for the Doom Patrol, or else he wouldn't have asked to draw all their entries in Who's Who (or their issue of Secret Origins). It would be almost 20 years before he got a chance to do a series though, and again, this is one I missed first time 'round. All I really know is that he rebooted the team, eliminated every other appearance from continuity, and brought back the characters killed by Arnold Drake. Well, everyone else had made a comeback of one sort or another, except Elasti-Girl. Cancelled after 18 issues, it was all undone anyway as Infinite Crisis restored the DP's continuity. So those Superboy-Prime punches weren't all bad.
