Like topic said.I look into Supes rogues gallery.And find like LEX,Brainiac,ZOD,Cyborg superman,Darkseid(Yes,I still considering him could counting as one of Supes villains)ETC,They all have some attractive traits.
For examples
Determined,Brilliant,Powerful,Ruthless ETC
So I wonder what do you think traits a good superman villain should have?
