Most one-sided fight in may favour that I remember has gotta be the final boss of Shadow Hearts if you had the final fusion, where you can beat "Metagod" in one move using the proper items and he's no challenge at all even if you don't.
As for the enmy's favour, it's gotta be in both Final Fantasy VIII & X when I ran into Omega Weapon without knowing what it was either time. Did pretty well until till he pulls out whatever cheap move he has in each game.
Also, and this is the nerd in me talking, Arthas VS Illidan. No way Arthas could take Illidan if he didn't have the ancient power of plot convenience.
