Mine would include the Elder Things from At the Mountains of Madness, and several other Lovecraft species like Yithians, Mi-Go and Flying Polyps. Also, the Chirpsithra from The Draco Tavern; Daleks, Sensorites and Menoptera from Doctor Who; the creature from The Green Slime; Twi'leks from Star Wars (no need elaborate on why); the shapeshifting aliens from The X-Files; Marvin the Martian; ALF; and many others.
