Hubert is the brother of Louise and Duane Quack and the son of Elizabeth Quack and Horatio Quack. He and his family were captured by Snively and held hostage until Dr. Quack agreed to work with Snively. They were later set free and have not been seen since. (StH: #49)
- Like the other Quacks, Hubert's name is based off one of Donald Duck's nephews, in this case, Huey.
