Robbie Baldwin, a.k.a. Speedball. He's been through Hell, and now it's time to grim him up. I was never a huge Speedball fan, so I have no particular problem with this development, though I'm reminded of a previous attempt to darken Beast Boy/Changeling in the Teen Titans about 12 years ago. That never "took", and this might not either. God knows Speedball had one of the all-time worst superhero names ever, being named after the drug cocktail that killed John Belushi. I'll be interested to see how Warren Ellis develops Baldwin's story - I'm expecting lots of rainbows and unicorns, personally... or not.
