I liked Dreadwing. He talks of honour, and occasinally adheres to it, but he's also a 'Con of convenience who's more than happy to break conduct if it suits him or his master/cause. Still, his loyalty and caring for his brother was nice, and his ultimate choice to pick his brother over his faction, and granting the Autobots the edge they needed, was quite noble of him. A shame he died, though. He was a pretty cool guy.
