C. Omega Flight Gold and Brown
I've always liked the heavier armored look OF brought in for Bill. He looks like a guy you do not want to @#$% with.
The problem with BRB in OF (I loved how he beat the crap out of sasquatch) is that he's so powerful that he doesn't really need a team. Just as Sentry, Thor, Hercules, and hulk are so vastly more powerful that it really does not make sense for any of them to be a part of a team. 99% of the threats could be handled by any one of them alone.
