Hmm I'd say Ganondorf in OoT. Not being able to lock on AND have to hit those power orb things back at him? Plus the floor falls sometimes to the point where there's only like 8 tiles not including the ones Ganondorf is floating over. All I have to say is Navi, you go through the whole game annoying me with your constant "Hey, Listen!" then you tell me you can't lock on to Ganondorf when I most need you...I hate you and this is why you're discontinued.
I think therefore I exist...but if i don't think much does that mean sometimes I don't exist? O.o
