Being a fan of comic strip deconstruction, I've started my own blog in that vein. It's called I, Snuffy. Basic premise: Snuffy Smith, the hillbilly petty thief and erratically lucky gambler, is actually a Bond level supervillain. He's biding his time by maintaining an unimpressive Appalachian front, and all the while his genius level intellect laughs maniacally.
This is partly inspired by Austin Grossman's Soon I Will Be Invincible, a superhero/supervillain novel that for me aroused more sympathy for the villain. (The greenhorn superheroine who narrates isn't bad, but most of the rest of them are insufferable. Popular kids who never lost the sense of superiority.) But it's also based on the idea that the people who you may be quickest to dismiss have raging hidden depths, for better and for worse.
Anyway, that's my "other self" for as long as I can keep it going.
