[Marvel & DC main comic universes] How common are superpowered beings in across both galaxies?
gpt
In DC Earth is unique in that many humans have a "meta gene" that will activate and gift someone superpowers when exposed to some type of stimulant or trauma as opposed to just dying like what should have happened to Barry Alan or Captain Atom. Abilities within most species don't vary much. There are some outliers. Mongol and his son are far more powerful than the rest of his species, though new comics may have changed this. Same applies to Lobo. Apokolips is mostly populated by Lowlies who aren't much more powerful than regular humans. But the New Gods they share the world with have either hyper advanced technology or a greater connection to the Source that sets them above.

Marvel has a great deal more variety due to the meddling in the genetics of people on many worlds by the Kree, Celestials, Beyonders, etc.
