Blackhawk and Hellboy

 

These pilots have seen a lot in their adventures, but would they be prepared for a collaboration with The B.P.R.D.?  It would be fun to find out.  Thanks to Patrick McLaughlin for this suggestion!

Captain America and Doll Man

 

I liked reading Doll Man tales when I was a kid, and that was no small accomplishment, given his costume and superhero name, neither of which were very cool.  The amazing  artwork I saw in the reprints featuring him was enough to overcome those hurdles.  I do wonder if the character might have been named Action Figure Man or something else had he been created a decade or two later.

Plastic Man and Giant Man

While I liked Bill Foster as a supporting cast member in Marvel Two-In-One, I wish he could have had a higher profile back in the day, perhaps as a member of the Avengers.  I think he did join year later, just long enough to be killed off in a crossover event.  Just more wasted potential for a great character.
