So great...I don't even know where to begin. 

Thank you JB.  I love it. 

Diamondback was introduced with the Serpent Society in the early 300's of the first series, when Mark Gruenewald was writing.  She started out as a bad girl but then she got a crush on Cap and eventually went over mostly to the side of the angels.

Not sure if that's still the case or if she's still running around in Cap.

I think it was really fun stuff, and very Super-hero-y in a good way. He wrote lots of thought ballons, giving lots of insight to what the characters were feeling DURING the action, which gave the action more oomph, y'know what I mean?

Highlights were the issues where Steve Rogers must become The Captain, and 'The Bloodstone Hunt' 6-parter(the latter of which spotlights DIAMONDBACK as a matter of fact)

I don't know if they've collected those issues, but back issues shouln't be too-too hard to find. (John Byrne artwork in a back-up tale in #350!).
