It has to be intuitive. If it's a spider character, players are going to expect characteristics similar to other spiders in the game (e.g. some alternative method of producing silk, or particular vulnerability towards fire). For instance, anyone can tell that Wolfgang is likely the most combat-oriented and strongest, also making sense for him to consume a lot of food and yet ironically be afraid of the dark fitting the stereotype. I don't really like Webber because he just seems tacky, like a little joke for more experienced players to scoff at. I'll withhold judgment until the Beta, though.
