Lookit me!

Guisecheck (only one section per game, please):

(Section 1) The longest word I know ends in a Y. I can name seven mythic D's (according to a certain rock-star's husband). My favorite Batman villain's name is a palindrome.

(Section 2) I know several vowel-less words. I can name the actor who played Captain Morgan Bateson, and name a novel that said character prominently featured in. My favorite Buffy villain's name was never said on the show, but I know it.

(Section 3) There's a word with three adjacent pairs of double-letters. The Brunnen-G have terrible __ but an awesome __. There's a hole in the world like a great black pit and the vermin of the world inhabit it and its morals aren't worth what a pin can spit. What name does it go by?
