Its dungeon master from the old D&D cartoon in the 80's. I never watched the cartoon when I was a kid I was more of a GI Joe and Transformers fan, but I have watched them since growing up and they are pretty standard 80's cartoon stuff. Anyway if you would like your very own dungeon master to tell you what to do and guide your online travels here is a paper-craft version you can print out of your very own!
Also if you want a villain for dungeon master to play with heres a paper-craft version of venger the villain of the show
These both come from http://cyberdrone.deviantart.com/ I didn't make them nor do I claim to have. If you liked these visit his site looks like he has a bunch more including some star wars ones.
