Cedric Diggory

Warning: Wikipedia contains spoilers.

In Harry's third year, in Harry Potter and the Prisoner of Azkaban, Cedric captained the Hufflepuff team which beat Gryffindor. In Harry Potter and the Goblet of Fire, Cedric was selected to be the Hogwarts champion in the Triwizard Tournament. When Harry is somehow also selected, Draco Malfoy makes Support Cedric Diggory badges for the Slytherins.

Cedric, along with Moaning Myrtle[?], assists Harry in solving the clue of the second task of the Triwizard tournament, in return for the help Harry had given him in the first task.

At the end of the third task Cedric refuses to take the cup without Harry, both of them having helped each other in the maze, so they grasp it together. The cup turns out to be a portkey[?] and it teleports them to Voldemort and his servant Wormtail[?]. Voldemort has Wormtail murder Diggory with the Avada Kedavra curse. Harry escapes, bringing Cedric's body to respect Cedric final wish, that he be brough back to his parents.

His girlfriend was Cho Chang. He danced with her at the Yule Ball.

His wand had a unicorn tail hair in it. It is remarked in the first book that "Always the innocent are the first victims." The character, Ronan, was referring to unicorns, but he could also have been forshadowing Cedric's murder. Cedric was the first of Voldemort's innocent victims after his return to power.
