The Heroic Table of Elements
Check this brilliant ‘Heroic’ table of elements featuring superheroes and villains from both the Marvel and DC Universe by Illustrator Matt Cowan who recently did a great Superhero ABCs, which you can see on his DeviantArt page. Matt’s seriously done his research on this and tried to use a more scientific approach as to what makes a superhero or super-villain tick, grouping them according to their team affiliations, date of first appearance, type of powers, species and overall power of the character.
He used superherodb.com to calculate overall ‘Heroic’ numbers to describe the value, as well using some artistic licence along the way.
