Re: How can they keep Cap 3 fresh?
Keeping Cap fresh can be done with a few psychological terror elements, with Steve wondering if the Super Soldier Serum is finally driving him crazy. Dr. Faustus or Karla Sofen (Moonstone) as a foe could work in that regard.
What if Captain America became as angry as Batman, even for a little while? I would like to see Steve Rogers go near-berserk with rage towards an enemy.
