DC Comics is full of incredibly powerful characters. With the likes of Superman and Wonder Woman, DC has many characters capable of making a grand impact on the planet. However, other characters have still proven to accomplish a lot, despite a lack of heavy-hitting abilities.

Heroes like Batman or The Atom rely on technology to give them an edge both scientifically and in battle. There are a number of brilliant individuals in the superhero community to explore without even diving into the supervillains of the DC universe.

Updated on December 21st, 2023 by David Harth: The DC Multiverse is known for the sometimes ridiculous power levels of its heroes and villains. However, there are also a lot of non-superpowered heroes out there as well. They often even up the odds with their superior intelligence. In fact, even among the superpowered heroes, there are plenty of extremely intelligent heroes. This has allowed these heroes to figure out ways to defeat the most dangerous threats, saving the Multiverse with their intelligence.
