When it comes to villains, there are ones like Sauron and Kronos(from PJ) who are seem like a primal or unstoppable force and there are ones like Galbatorix(from the inheritance cycle) who are weak at first or are traitors etc- But the question is which kind is better and more popular Type A or B?
To be honest I don't particularly know considering both sound good and both are popular with me. But if I had to choose it would have to be Type A, because I like the thought of the heroes struggling against this unstoppable villain that doesn’t seem to weaken at all. Take Voldemort for example he seemed like an unstoppable villain but then he was defeated in the end.
