Who are the best DC comics villains?
Who are some other memorable DC villains?
Well, there's Darkseid, who is one of the most powerful and ruthless villains in the DC universe. He's the ruler of an entire planet and commands an army of loyal soldiers who will do anything to further his goals. There's also Black Adam, who is a former hero who was transformed into a villain after being corrupted by power. And then there's Sinestro, who was once one of the greatest Green Lanterns but turned to evil and became one of their deadliest foes.
