Black Bolt vs either Firestorm or Classic Comet would be a good fight.
I can make arguments for either side winning in a match up between BB and FS.
When it comes to BB vs CC I'd Comet takes the slightest of majorities. Having class 100 physicals FTL speed, high end brick durability combined with o e of the best TP/TKers around and somone who with his mind over matter has exibited mattter manip on a low scale, just makes him too versatile.
My problem is I don't know starhawk at all. So in regards to the team up can't really make a comment.
