Mi-Gor is a sinister zombie surgeon working for Rabid Jack. His zombie pirates have laid siege of Harmony Island and turned the monks into zombies. Mi-Gor built Barrelchest to be his bodyguard. Mi-Gor has a problem with his breathing system, so he has to wear a complicated breathing device, which is a problem when he tries to do an evil laugh.
- Mi-Gor's name may be based on Mi-go, a fictional race that plays a role in H.P. Lovecraft's Cthulhu Mythos. The fact that many of its experiments involves lobotomizing brains to terrible inventions of war makes it similar to the Mi-go.
- It is also likely a variation of the name of the universal assistant archetype Igor, a character present in many Frankenstein adaptations, though not in the original novel by Mary Shelley.
- Mi-Gor's difficulty breathing and swollen chest may be a reference to the fatal lung disease emphysema, which causes victims to develop a "barrel-chest" (the name of the boss in The Great Brain Robbery) and a deep voice, both of which are prominent in Mi-Gor.
- His examine text is likely a reference to Nuprin, a painkiller from the 80's which used the slogan "Little. Yellow. Different.".
