Ah, for now, I've only come up with a couple of not-so-convincing Barbarians:
1) Morning - because he has a spaceship in his avatar, and spaceships travel from island to island... well, it's obvious... he's quite the barbarian.
2) Gur - supposedly, he has England in his signature, and it was once a leading "maritime" power. So, he also seems like a barbarian.
