Michael D. Hull

A barely passing surgeon specialized in general surgery, working under the research facility before the major shutdown. 

Has a fun and perverse personality, often lighting up the mood in a usually dark atmosphere. He quotes obscure Anime/Hentai references that nobody but him knows about.

Even though he lacks professionalism sometimes, he gets serious when the time comes for it and cares deeply about the bonds he makes.

A notable co-worker for Florence and Serenity
