In a franchise called "Ghostbusters" you'd think it would be all about ghosts and other supernatural things. Well, it is, but every once in a while you get creatures from another planet. We got Fuggs, Merks, Kryds and their leader Podsnap. In one Slimer! episode an alien appears apparently. (I haven't seen the episode) Pretty crazy, but not totally unexpected.
The ones I listed above are put into the Corporeal category, but I was thinking that there should be an Aliens or Extraterrestrial category, but I don't know.
What do you guys think? Should there be a special category for aliens? Also, what do you think of aliens being in the Ghostbusters franchise? I think its pretty crazy.
