Comics history quiz masters - Who was the original "mutant" in the history of comics?

I still say Namor counts, regardless of when they started calling him a mutant or if cerebro detects him. His breathing underwater or on land don’t count, as those are each inherited from a parent, but the little ankle wings that let him fly and his extreme strength make him a mutant, because neither of his parents had those powers.

That, and his prodigious strength. He’s in, I think, the 85-ton range on land (i.e. on a par with Ben Grimm) and 100-ton underwater (he could go toe to toe with Thor or the Hulk, due to homefield advantage). A handful of Atlanteans are that strong, and of them, only his blood relatives have the ankle wings.

Isn’t it time for one of Namor’s illegitimate sons to make an appearance? Or one of his alien monster kids by Marrina?

Don’t forget artificially mutated humans (Savage Land Mutates), artificially evolved humans (Alpha the Ultimate Mutant, the Futurist, any spindly giant with a disproportionately huge head with godlike intelligence and abilities), artificially evolved animals (Knights of Wundagore) and hidden races (Jack Frost’s people, Red Raven’s people, the Mole Men, the Cat People, etc.).

If I remember right (though my knowledge may be out of date) Spider-Man is considered a mutate - of a group who do have genetic oddities but who if left alone would not develop any powers, but if given the right stimulus (which would, often, kill anyone else) that and their body would react in a similar way to a mutants. I think the idea of this was brought in mainly to explain why some people got powers from being involved in radioactive disasters while others just dropped dead.

Wait - so why did the Kryptonians all choose to live on the one planet where they don’t have super powers?

This is never (so far as I know) specifically explained for Daxamites, Kryptonians. or myriad other advanced races that have godlike powers off their own planets. The common take on Kryptonians since Byrne (IIRC) developed the notion of Kryptonians as a fairly xenophobic, emotionally rigid “master race” is that (powers aside) they regard most other races as lower species and do not wish to associate with them.

Daxamites it’s pretty well explained by the fact that a very common element (lead) is swiftly - and, until the 30th/31st century, incurably - lethal to them. Leaving their planet is pretty much suicide.

Now, a religious prohibition, and xenophobic ‘anything out there is evil and dangerous’ aspect has been layered on top.

Kryptonians, the answer has changed over the years - in the 80s and 90s, there was some story I vaguely remember involving genetic engineering and making it so they couldn’t leave Krypton (I have no idea what was supposedly changed that allowed Kal-El to leave).

Currently, it’s historical - they had a period, several hundred years before the birth of Kal-El, where the Kryptonians were tyrants, using their powers to rule a galaxy-spanning empire.

After ‘doing this kind of makes us evil’ sunk in, they pulled back. Leaving a lot of former subject species with grudges and the ability to stockpile arms. Combine that with the urge to go out an explore being uncomfortably close to the urge to go out and conquer for many Kryptonians, and a fairly understandable urge to just close the door and pretend the rest of the galaxy doesn’t exist developed.

(Also, there’s not really that many races like the Kryptonians and Daxamites…they’re the only ones currently canon, and there were only 2 or 3 others that I know of…aside from the rather odd case of Kanjar Ro getting powers under the 3 suns of Rann.)
