Nymphadora Tonks
Died: Fighting for good.
Harry remembered the first time he had met Tonks. A group of witches and wizards had come to collect him during the summer before his fifth year at Hogwarts. Mad-Eye had been leading them but there were a few people he didn't know. One of those people was a perky-looking young witch with an alarming shade of bubblegum pink hair who had greeted him with an enthusiastic "Wotcher, Harry!" Her name was Nymphadora but she much preferred her last name over her first. Tonks had always been optimistic and entertaining. There was never a dull moment with her around.
And then she and Remus had gotten married. And after that, she had had a baby named Teddy who would no doubt have been doomed to a life of constant torture under the new regime given the fact that his father was a werewolf and his mother was a metamorphmagus. So they had fought. His parents had fought for a world in which their son would be protected. They died for it, but they died a noble death. Though his real parents wouldn't be there to see him grow up, Harry knew that people would tell Teddy of his parents' bravery and how they died so he could live.
A/N: I have no idea if that's why they did what they did but heck, it sounded good. Haha soooo…review cos reviews = love = the only thing that can kill Voldemort.
