Which one is your favorite?
I liked all the newbies. They can spread them around the scene.
The role of moderator seems fine to me. But, the legendary character seems a little strange. I don't think these "barries" look that good. He seems more like a bossy fat man who is more of a villain than a respected character. I think the legendary character should seem more like a warrior hero, someone everyone admires.
In the case of the character Satoshi, the 3rd figure seems very interesting and the most appropriate. I would just change the bat... I don't know how, but I think it could be a little different.
In the case of the legendary character I visualized it how it might be perceived from the eyes of some lower status members, not as how they would be in reality.
The idea is debatable of course, as is most other things at this point so thank you for your comment!
