I like Doctor M's design. I went through a lot of them before settling on the on he's got now. All that's clearly visible are white shiny fangs, glowing green eyes, and a fluttery cloak. Otherwise, he's like a big, spiky black shadow. He can sprout tentacles and claws and scales and such.

He uses his tentacles to freak people out, really. Amit offers Sophie a box of Junior Mints and the Doctor reaches over with one of his tentacles to take some. Both of them freak out, but he just shrugs it off--"What? WHAT? You offered."

Also, I hate the "e" key on my keyboard. It isn't pressing down properly and now I have random e-less words in my entries. Bah!
