Robin #10 had Dick Grayson and Tim Drake teaming up, both as Robin. Tim notes that Dick is a far better physical Robin (an acrobat, remember?) while Tim is far more tech-savvy and a hacker.
A villainous one, but Parallax pretty much wins. The universe is dissolved into nothingness, and even though the heroes are in a position to fight him, they don't really have a choice but to let him do his thing. The universe is gone, and he is the only one with the power to actually fix anything. A universe created by a madman is better than no universe at all.
