3. Lily Potter
J.K. Rowling reminds us that love really is all you need through the beautiful Lily Potter. Lily defeated Voldemort and continued to halter his activity for years simply because she showed outstanding amounts of bravery in protecting her son, all because she loved him; she cast a spell so strong that Voldemort just couldn't exist. Voldemort wanted to recruit Lily and James to follow him as Death Eaters so they were clearly also powerful at a young age or Voldemort fancied Lily and had to recruit James to admire her on the sly. Both valid indications of her power and appeal.
