Aside from being a demon, Urkonn has his own backstory, which I found intriguing. As Melaka's trainer, he relentlessly prepares her for her worst nightmares, including betrayal from those she trusts.
Urkonn used unorthadoxed methods to train Melaka that ultimately led to his demise. I highlighted him because I liked his interactions with the slayer and wanted more.
What do you think about Urkonn? He looks like a bad a**, huh? Were you (are you) a Buffy fan? Have you read any of Whedon's comic books?
On another note, can someone tell me why Joss Whedon doesn't have a website? I mean, for the love of Peter, he's on Facebook. Good grief.
