Marty's Assistants are twins who assist the president of the Stay Puft Marshmallow Company, Marty Tillis.
After Marty Tillis' initial offer to the Ghostbusters didn't go as planned, the assistants skillfully laid out a seat for Marty and gave him a drink. They later accompanied Tillis to Battery Park to oversee the filming of a commercial.
They are well coordinated and smile a lot but don't speak.
- On page 11 of Ghostbusters Issue #13, the assistants make a non-canon cameo sitting in a row behind Janine Melnitz and Roger Baugh
