I really like 2 and 3, but 2 especially. also, when you say Shaggy, do you mean "stoner best friend" or "constantly getting in over your head, and needing to be bailed out." Both are fun
Needing to be bailed out, easily scared ("like, zoinks!"), not very capable at fighting. I thought that this type of character would be represented well by some of the Mundane's moves. Being a reporter for a tabloid is a good reason why the character is hunting monsters with professionals and wizards, and therefore (I think) could work with any of those groups.
