The Duke is not known to have any canon relationships in the series. However, it is possible that he had a crush on Toph. The Duke really seemed to be fond of her and always enjoyed being in her presence. He allowed her to throw up in his helmet when she got seasick. The Duke was also seen glaring at Sokka at one point when Toph was interacting with him and she did have a crush on him. After the war ended, he approached Toph and hugged her.
The Duke has a small amount of popularity in the Avatar fandom. He is very commonly shipped with Toph. Since all of the members of Team Avatar besides Toph were in a relationship at the end of the series, many fans decided to ship The Duke with her because it gave her a love interest and a lot of fans felt that The Duke would be the most likely romantic partner for Toph. When it was revealed that Toph had a daughter named Lin, many fans speculated that The Duke might be the father until it was revealed that the father was a man named Kanto. However, The Duke's birth name is unknown so some fans speculate that Kanto is actually The Duke's real name.
- The Duke is sensitive about his name and feels offended when people call him "Duke" instead of "The Duke."
