His quotes against "The Player/Avatar" (also a hints for the plot):

~ A Revenge? Bah! Not against you!
WE have a different intention. An Excellent Plan... A Benefit!

~ The Final Phase shall be completed with you!

~ The Jackal is right... Your FEAR is just... Delicious!
I can't resist its taste! What a Boost!

~ You won't find him here anymore inside of me.
But it means, that... I AM yours Favorite Character!

~ You will end up just like me!
Being imprisoned in another's body... to become as "The One"!
