The Invincible Iron Man #4 comic book from Marvel Comics Group
It only took four issues for Iron Man to get a respectable villain.  The classic Unicorn finally saves the day.  Sure his helmet looks like a hair dryer and that unicorn on his costume makes him look like a little girl, but overall he is pretty cool.  At least compared to the Freak and the Demolisher.
