8. Alison DiLaurentis
To be honest, we’re not sure Ali really belongs on this list, but since she finally cracked the title sequence, we thought she deserved a spot, even if she’s dead (pun intended) last. Ali is the reason for all her friends’ peril. Yes, A may have brought them all closer together, but we liked the liars better as a foursome. She’s mean and manipulative and we’re sure she knows more about Uber A than she’s letting on.
