Strong oppose The correct title both in French and in English is Aterix or Astrix not Asterix an Obelix See eg this cover on Wikipedia and all other covers The series is listed as The Adventures of Asterix on Amazon the official site  only mentions Asterix albums etcetera I have not found any reference that Asterix an Obelix is the proper name although it is indeed also referenced thus by many that is why it is a redirect to the official name
