With 70 years of super-hero comics behind us, there have been a lot of super-powers on the printed page -- so many, in fact, that even the most dedicated comics reader can occasionally have a hard time keeping them straight.

That's why ComicsAlliance senior writer Chris Sims took it upon himself to finally get things organized with The Periodic Table of Super-Powers, an arranged listing of 84 common (and decidedly uncommon) characteristics of your favorite super-heroes!

(Click for the full-sized version!)

With this table, you can easily represent your favorite super-heroes' power-sets in simple, not-at-all-far-too-complex-to-be-useful formulas!

For instance: Superman comes out as: OAFSISpVxVhSn

Wolverine can be represented as XWxHSn

Poison Ivy is, of course, Iv

And Legion of Super-Heroes wannabe Arm-Fall-Off Boy is simply Af.

Why not try your hand at it and see which power sets you can cobble together?
