Motörhead's Lemmy Kilmister may cut a daunting figure in real life, with his black Fu Manchu mustache and biker duds, but he's larger than life in the virtual world. He's a king, with his own domain, aptly named Lemmy's Castle, guarded by hulking, horned monster security guards and demon spawn inspired by dozens of his own sketches.

His digital dwelling is all part of the newly launched virtual music world ROCKtropia, a virtual planet in the online 3D Entropia Universe, a massive multi-player game in which people interact using avatars. "In my world, you go to jail telling your kids bedtime stories," the 64-year-old says during a break recording Motörhead's newest album, a dirty sparkle in his eye. "I want big stinking bats with horrible noses, or flying anteaters. In my world, most people would die."

For a guy who claims he hates computers, and recently got his first laptop, he's passionate about this brooding online landscape.

"It's goes to show I do know what's going on in the 21st century," he says. "I want to take  over the whole world, in the end. Look at the size of my security guards. Clone them, send  them out. What's the point of having a castle if it isn't scary?"
