Duckworld
Set in Howard the Duck's home-world and home dimension. This version of Doctor Strange is Ducktor Strange, an anthropomorphic Duck. In this reality, he is still a Sorcerer (the "Mallard of the Mystic Arts"), but is also a drunken derelict, who seems to live in alleys drinking "sorcerous sauce" (alcohol). He has appeared in Howard the Duck (magazine) #6, wherein he sends Howard and Beverly back to Earth, and in She-Hulk (vol. 4) #20, wherein he helps Stu the Intern return to Earth (since Stu's extensive knowledge of Marvel Comics continuity reminded him that he could find the Ducktor and how he could be returned by the Mystic Mallard).
