Wind Dragon (Samurai) Restricted characters A few characters have been cited by writers and producers as "off-limits" at various times during the production of the various shows, though they are allowed to appear in the comics based on the show. Adam Strange Adam Strange, was originally supposed to appear in "Hunter's Moon", but legal rights prevented that from happening. The episode's original title was "Mystery In Space", the name of the monthly comic that Adam starred in.
