Well, you know what I look like, and you know what I sound like, but my personality isn't shown nearly as much.
My favorite anime is either Ouran Host Club or Star Ocean EX (Yes, I know, shut up).
If I'm not done up, I look fairly normal, with blond roots beneath my raven-black-dyed hair, typically wearing a gamer-related black shirt (Hacker's Manifesto, Sonic's Eyes, "Control Freak", "My Thumbs Can Go All Night", "Back In The Day" (Pacman), and the like)
If I am done up, my persona changes significantly. I gain a bit of an evil voice (will post in "post your voice"), and I become more philosophical, because I actually think before speaking. What I wear when I actually bother to dress up is dependent on what I have that isn't trashed, but for the most part, it's in the direction of Zio (from Phantasy Star 4) or Testament (from Guilty Gear XX), who both kinda fit the "ideal me" that I have in mind.
I want to be sophisticated, wise, and witty, but I'm not, and I know it. I'm a bit of a goofball, usually, and I'm the entertainer of any group I'm in. I love making people feel better, and making people smile, regardless of what else is going on.
If you need any more info, just ask.
