Baddest, yet Most Obscure Villains.
These are the characters that fall into one or more of these categories:
1. # of Showings- Haven't made many appearances.
2. From the Past- Haven't been in a book in a LONG time.
3. 1-Shot-Wonder- Have only been in one story.
But... they are SERIOUS Threats.
Just to throw a couple out there, I would say -
Man-Beast (this panel doesn't even show his other powers)
and one of my personal favorites...
Koontz Satellite Killer (anybody else remember this thing tearing up Iron Man?)
