[The Legend of Zelda: Ocarina of Time] Shadow Link (Water Temple)
No megaton hammer, no bombs, no nothing. The first time I did that fight it was just me, my sword, and my shield. To this day it remains one of the best fights Ive ever had.
[Super Mario RPG: Legend of the Seven Stars] Culex (Monstro Town)
