I don't get why using the same dynamic is a bad thing. It didn't stop my sister and me from loving almost all of them without ever realizing the similarities until now. I like that It follows a pattern.

I think I know why there's only one weasel main villain. You see, the least weasel is the smallest mustelids, the smallest member of Carnivora. They are only 5 to 7 inches long, smaller even than a rat. On top of that, they aren't known for their intellectual capabilities. The one advantage the average weasel has is speed--their reflexes are like lightning. Ferahgo is a smarter than average specimen, which is how he came to power.
