Personally, I think Hidan, Minato, and any amaterasu user are extremely terrifying. that horrible feeling of the unknown attack from Minato, or the absolute fear of the awaiting pain/death after you've been struck by Hidan. Also, the idea of burning alive by an inextinguishable flame that appears instantly would make anyone run away. But these are just the main ones for me, of course there are others like orochimaru, kakuzu, madara, obito, third hokage, kisame
