There are LOTS of superpowers out there.
There are so many that it is very easy to get confused. And then you run into people with similar looking or acting powers, clones, evil twins, alternate universes, etc… it just gets messy!
The folks at Pop Chart Lab created a picture that pretty much gives the rundown down of (almost) every superpower. The char, entitled The Illustrious Omnibus Of Superpowers, and is a “taxonomic tree of over 100 wondrous powers and abilities, with over 200 superheroes and supervillains as examples thereof.”
It separates powers into six separate levels: Mastery, Weapons-based, Animal Powers, Powers of the Body, Powers of the Mind, Force Control and Object Manipulation. And each level is sub-divided into different areas. It is an incredibly well-done and thought out guide. Off the top of my head, I cannot think of any character that does not fall into one of the categories.
The chart is so well done and detailed, that it will take you a long time to get through it. That said, if you are a fan of superheroes, you owe it to yourself to check this one out!
