I'm going to go with Luca Blight from Suikoden II.
I confronted him with a party of six of my strongest, and he beat them. (I lvled these guys like I had no future) And then a second wave of six of my guys, a fierce battle ensued, and again, Luca was the victor.
My third party rode into battle, and he wiped five of the six members out. I survived with one person (Nanami)
and was like "Ohhh damn.. I lived?"
