A hero is defined by their villains, and the world of superhero comic books is filled with some of the scariest and silliest bad guys around. Rogues’ Gallery aims to settle the score and determine who is the true arch-nemesis for some of our favorite superheroes, and we need your help to do it!

This week we're looking at the villains of Earth's Mightiest Mortal, the hero known as Shazam! Whether it's through magic, science, or a combination of the two, Shazam has some of the most memorable villains in comics, but we need your votes to find out which one is the best of the worst.

The number one seed this week might seem to be Black Adam, who represents a complete corruption of the power of Shazam and can go toe-to-toe with the hero like no-one else can. However, Black Adam has been an ally as much as an enemy in recent years, and Doctor Sivana has been making a major play to be The Big Red Cheese's ultimate enemy .

Then of course there's the conniving Mr. Mind, who was the one to gather many of the former Captain Marvel's enemies together to form the Monster Society of Evil. There's also Captain Nazi, who killed Captain Marvel Jr's grandfather and is, well, a Nazi; and The Seven Deadly Enemies of Man, who represent the absolute worst aspects of humanity.

Let us know who you think gets the top spot for Shazam’s number one nemesis below, and we’ll be back in a few weeks with a countdown of his top ten best and baddest villains. You can vote for up to three selections in the poll!
