Favorite/scariest Ghost??

For me all of the Ghosts are great, unique and scary in their own way. But who was your favorite and scariest ghost? My favorites are The Angry Princess and the Jackal. Now for scariest ghost for me, the scariest Ghost for me had to be the Jackal! I found him so scary with his sharp teeth and fingernails and it was scary how fast he was. And it shows how dangerous he was when Dennis found out his cage had been open. And he also didn't waste anytime on attacking people. Someone might say the same about the Juggernaut but for me with him he seemed to be on a mission to attack one person and that was Dennis, they had this little moment in the beginning of the movie and you could tell he had been waiting to get out to get to him. So he too was scary but nobody beats the Jackal.

Anyone else?
