I'll try to make Disney/Pixar characters in young and stylish concepts, some kind of "students", something like the new Pixar's Movie: Monster University.
Arthur is a member of the fencing team despite being thin and wimpy. Phoebus is one of his best friends and from who has learned most of his moves.
He is loyal to his friends and he's always willing to learn new things being his favorite class History, (with Professor Merlin)
Hope you like it!
