For the Wolves I'd suggest Loupback, who can redirect any attack back to it's source.

For general, I'd happily volunteer some of the villains I used in my old Champions campagin, which was like it or not very Silver Age, for all that I was reading '80's comics: The Atomic Playboy (suave and supremely radioactive), The Menagerie (my take on Dragon Man, an android of amazing animal parts and powers), Gulag-13 (if you need any Soviet state supervillains)... I have more. If I can find my old notes. :)
