it's the green knight! withering wizards and diseasing dudes!
the green knight always seemed like the jerk of the group. like the raphael, all attitude. he was the first guy i went through the game with so i'll always have a soft spot for the little asshole. who seriously poisons all the other knights and then runs away, coming back only after they're dead to make out with the princess!? i did, and i'm sure a lot of you guys did as well :D.
