When I was in high school, I started writing a serial novel, longhand, set in the Arthurian mythos, and influenced not incidentally by Marion Zimmer Bradley's 'The Mists of Avalon.'
I think that Batman loses his efficacy and mythology if he's got too many people around him. That's what the Justice League is for, you know what I mean?
There are so many great characters because one of the things that makes Batman fantastic is that Batman is tragic. I've said this elsewhere; I've said it over and over again, but the beauty of the character is that he's a Don Quixote.
I think when you're working with a character that another writer is acting as - for lack of a better word - custodian of, your obligation as a professional is to not do anything that violates that 'primary' take.
'Alpha' is a very fast-moving book. It doesn't lend itself to laborious introspection and the navel-gazing that some stories can fall prey to.
Every character needs an adversary - one who is both challenging and a contrast for the hero. The best adversaries reveal something about the character they're contrasting.
