User blog comment:KillRoy231/Big Bads of each season?/@comment-1194123-20180313131038

I don't know what specific pages for "main villains" you refer to on the Supernatural wiki, but to be honest, I don't see much of a purpose for it. First, we already have a "Masterminds" category, which pretty much lists all the "big bads" in one place. Second, it lends itself to different interpretations for who is a "main" villain and who is a "secondary" during a specific season (I think there were arguments when the above category was made, so there's that).
