That's a question I'm still working on, myself. Online, I'm known as Shadow D. Wolf, or just Shadow. In the overrated realm of "Reality," most people call me Kerry, though I've been known to answer to my online name as well.
This photo should give you a general sense of what I look like, though it's a couple years old. I'm about 5 feet, 6 inches tall, weigh about 200 pounds (need to lose a few of those), and most of the time, my eyes are blue. The reason why I say "most of the time" is that, strange as it seems, they do change color from time to time (and I've been accused of wearing contacts more than once). I've known my eyes to turn green, or even violet on rare occasion. Your guess is as good as mine as to why. *Shrugs.*
Okay, now it's time to weird you out. *Takes a breath and hesitates.* I am a werewolf. No, that doesn't mean that, when the full moon rolls around, I get all furry and run around on all fours (though I must admit that might be kinda fun). I'd be lying if I said the moon had no effect on me at all, though. As a general rule, my senses seem a little sharper, and I tend to have more energy under a full moon, though this could just be my imagination. Anyhow, I'm what's known as a Spiritual Therianthrope—that is, I believe that I am spiritually a wolf. This is not to be confused with Lycanthropy, which is a mental illness (I'm not crazy! Really!). Basically, I have the personality of a wolf, sometimes I act like a wolf, and I can use "merf" in a sentence (no, not really). Sometimes I even dream of being a wolf, which is pretty fun.

As a general rule, I tend to be a fairly quiet guy, especially around people I don't know well—some would even call me shy (although I tend to get very talkative when hyper, nervous, or loaded-up on coffee). Those that do know me well tend to say that I get emotionally carried away over little things. I'm also a pretty good listener—at least, I like to think I am. I'm one of those people who can meet someone new, listen to them for a while, and in about five minutes they'll start telling me their whole life's story.
Among my friends and (online) family, I'm known as the "Pack Psychologist," which is just a fancy name for someone who gets his shoulder cried on a lot. To be honest, I have to say that I enjoy listening to their problems, mostly because I know how a good venting session can feel. That said, it does get old sometimes, especially when it's the same person constantly whining about the same thing. Venting is one thing, but being a drama queen is quite another. ;-)
