Do you remember, the Kryptonoid?

[Captain Kal]

For the most part, that was true.  Though we had exceptions like Superman constructing a Kryptonian revitalizer to revive a dead alien humanoid.

In the 1960s, the Kandorian scientist, Reg-En, invented an instant healing ray that he used on Superman's Flame Dragon bite wounds. (It actually didn't hit me at first that 'Reg-En' was a play on 'regeneration' until rereading that story years later. D'oh!)

Brainiac took notes about Kryptonian mind control devices used on their mental patients.

I think the inconsistencies of Kryptonian medical science span the entire supermythos and not just the 1970s.

Kryptonian science & technology was centuries, or several millenia (at least) in advance of earth.  Even scientists/science fiction writers like Isaac Asimov would be unable to do it justice.  Consider this example the old tv series "Voyage to the bottom of the sea",  produced in the 1960s & took place in the 1980s.  They had their characters using slide rules.  They couldn't predict the pocket calculator, which hit the market by the early-mid 1970s.  And of course next to nobody can predict all the breakthroughs & paradigm shifts that our science & technology will go through in the next 25, 50, or 100 years.  Or the next several centuries or millenia.  Jules Verne supposedly predicted late 20th century society, science, & technology.  In a story that was unpublished for over a century.

Did anyone else groan at that? :lol:

Heh.  I've groaned at a LOT of Silver/Bronze Age Superman stories!
