[Superhero Comics] Why don't aliens get superpowers?

Yes, I know there are alien superheroes and Supervillians. But they tend to be just, like, naturally powered. Superman, Venom, Martian Manhunter, Starfire- sure, they're superpowered from our perspective, but from theirs, they just have normal abilities. Venom is just another symbiote, which makes him very powerful to *us,* but he's not got *powers* any more then a bear has powers.

Or, like the lanterns, they had advanced alien tech which, again, not really powers so much as owning something.

But where are the super aliens? Where's the Skrull who was bitten by some radioactive animal and got its proportional strength? Where's the member of the Reach who was struck by lightning and became an avatar of the speed force? Given how many superhumans there are, you'd think the superaliens would show up in the various invasions of earth, but there's maybe a handful at most. The Heralds of Galactus and Lightning Lad are the only ones I can think of.

What's unique to humanity/earth that means we get all the cool powers?

In case of Marvel.. humans were experimented on by celestials in prehistoric ages. That is the cause of mutations and superpowers.

Some other races like the skrulls have been shown to have mutants. But normally they’re killed as soon as it’s clear.

I think the kree have a strictly controlled breeding program weeding out irregularities.
