1)I really enjyed the battle against freya in start oceaan : till end of time . she keeps standing for over 20 minutes
she hits you where ever you are .. with A LOT of damage , and most of your own attacks cunsume hp to ...
2) Or againsts strife in soul caliber 3 .. he's extreemly fast . and the damage he inflicts he get back in his hp ..
And you need to kill 5 of the strongest enemies before reaching him . .. you can't refill your hp
.
3) Penance from FFX .. no need to explain
(hint : it took me very long but he fell down
)
4) the first boss of the wind waker (that scorpion dude) .. i still think he's hardest bos of the game : legend of zelda : the wnd waker .
5) for fun .. Lady from shadow hearts : from the new world .. with my lvl 84 party (i thought) she went down in 3 turns xD
