Billdora

Billdora is the het ship between Bill and Tonks from the Harry Potter fandom.

Canon
Bill and Tonks met during their Hogwarts years in the 1980s. Bill was two years ahead of Tonks, and Bill was in Gryffindor while Tonks was in Hufflepuff. Bill and Tonks had a mutual good friend, Jacob's sibling.

One Christmas, Bill and Tonks were among the few (alongside Bill's brother Charlie, Jacob's sibling, Rowan Khanna, Penny Haywood and Merula Snyde) to stay at Hogwarts when most returned home for the holidays. During this time, Tonks met Bill's parents, who came to visit the school. Bill and Tonks had a conversation with Molly Weasley during the Christmas Feast.

Some years after graduation, as the Second Wizarding War began, Bill and Tonks became members of the reformed Order of the Phoenix. They were on good terms with each other and fought in several battles. During the war, Bill started dating Fleur Delacour. His mother Molly and sister Ginny did not approve of the relationship, wanting Bill to marry Tonks instead. Bill and Tonks, however, did not have any romantic feelings for each other, as Tonks was in love with Remus Lupin.

During the Battle of the Astronomy Tower in 1997, Bill was injured by Fenrir Greyback, and as Fleur continued loving him, this inspired Tonks to publicly declare her feelings for Remus. Although Remus did not feel worthy of being together with Tonks, the two got into a relationship. Both couples got married in the summer of that year.

Bill was one of the first to learn about the birth of Teddy Lupin, the son of Tonks and Remus. Later, Bill and Tonks fought in the Battle of Hogwarts, where Tonks and her husband were killed, leaving Teddy an orphan. A few years later, on the anniversary of this battle, Bill and Fleur had a daughter called Victoire. Teddy and Victoire started dating in their teens.

Fanon
The pairing is not very popular, and most fans prefer their canon ships or some other pairings over Billdora. It is not a very well-known ship either. However, it does have some fanfictions, but fanart of the ship does not seem to exist online.
