That just depends on the person and what their greatest fear is. Tower of Terror is the scariest if you hate big drops and falling. Rock n' Roller Coaster would be the scariest if you are afraid of high speeds and/or going upside down (it's the only ride at Disney that has inversions). The more intense "orange" version of Mission:Space would be the scariest if you hate spinning and get motion sickness from it.
the most scariest thing in the world is bloody Mary n the graveyard and the green light coming up from a grave.
