Inspired by @nathanielrepay & @sarahgorman edited for clarity for @Lisa_Fav who disagrees with my choices.
  1. Minerva McGonagall
    She. Literally. Turns. Into. A. Cat. Do I need any more explanation?
  2. Luna Lovegood
    She's a bit weird and crazy but you grow to love her. She's also supportive af of DA etc etc. would do anything for her friends. Has a way of going with the flow when things go wrong (I'm about 50/50 with her on that one)
  3. Crookshanks
    There's more to him than meets the eye. He's very in tune to untrustworthy people. If he were a person he'd be a Slytherin.
