Comics Alliance has posted a Periodic Table of Super-Powers, detailing not just powers but origins as well.
Click through to the original article, where they link to a full-sized table that you can actually read.
Let’s see if we can come up with the “chemical” formula for the Flashes:
Speed, Intangibility, Time Travel; Scientist struck by Chemicals
Speed, Intangibility, Time Travel, Detective; Scientist struck by Chemicals
Speed, Intangibility (sometimes), Time Travel; Chemicals, former Sidekick, Legacy hero
Speed, Intangibility, Time Travel; Mutant (closest I could come up with to inherited powers), Time-lost, Legacy hero.
Arguably you could include H=healing (super-metabolism) & Is=invisibility (they can move too fast to be seen), or Sn=super-senses (seeing things more quickly, or moving so fast that radiation is red– or blue-shifted into the visible spectrum), etc.
Who wants to try the Rogues?
