Arthur Hawkins

Arthur Hawkins, known as Arthur Hopkins in the Japanese anime, is the American best friend of Solomon Muto and the grandfather of Rebecca. His original Japanese name is kept in the English video games.

In the manga and first series anime, Professor Hopkins only appears in a photograph with Sugoroku Mutou, and his name is never revealed. Although he is briefly seen after Rebecca finishes her duel with Yugi, his major appearance is in the Waking the Dragons arc, where he investigated the history of Atlantis and of the Orichalcos. He gives information to Yugi concerning both of them and is instrumental in discovering the location of the lair of Dartz. He also appears during the Grand Championship arc.
