|Residence||Realm 3009 (Neo-Pakistan)|
|First Appearance||WORST FILM EVER (CHRISTMAS SPECIAL)|
Dr. Sack is an infamous doctor who lives in Realm 3009, whom Frank is sent to in the episode WORST FILM EVER (CHRISTMAS SPECIAL), to help cure Dade's sickness. He has some affiliation with Chin-Chin, the Dark Lord being the one who sends Frank and his goons to the doctor. He also may have a fear of broccoli, as Brock Lee intimidates him more than Frank's other henchman, who wields a gun. It is implied that he has healing powers even greater than The Shaman. The fact that he's recommended by Chin-Chin himself might also suggest that he's one of the most powerful healers in all realms. He states himself that his name is not 'Sack', but since Chin-Chin told Frank his name was Dr. Sack, that is fact. He also appears in the book Francis of the Filth.
Dr. Sack appears to be in his late 50's. He wears glasses and a suit, along with a red tie. He hides a gun under his suit jacket and holds a cane in his right hand.
Frank is sent to Neo-Pakistan by Chin-Chin to find Dr. Sack to help cure Dade. He is reluctant to help him, however, as he doesn't want to roll around in Frank's filth with him, and threatens Frank and his henchmen (two black kids Chin Chin found in a parking lot) with a gun, and when they don't respond, he threatens them yet again but with his cane.
He is psychic, seeing as he could tell that Frank wanted him to cure his naked bald-headed man who throws up chocolate.
