Regardless, like most superhero movie sequels, Doctor Strange 2 would surely up the villainous stakes, so Stephen Strange would surely welcome having Brother Voodoo by his side.
Much like how Doctor Strange is stationed in the United States, Brother Voodoo set up his base in Haiti, but he has fought alongside the good Doctor on many occasions around the world.
Brother Voodoo was introduced in 1973’s Strange Tales #169 as a Haitian who came to the United States to become a psychologist.
For a time, Brother Voodoo succeeded Doctor Strange as the Sorcerer Supreme, but Stephen inherited the title again when Voodoo sacrificed himself to stop the entity Agamotto from regaining his fill power.
