Do you think that some cabins have demigods with powers that fall in the range of their parent's, but is completely opposite the rest of their half-siblings? Say, an Apollo kid who makes people sicker or a an especially hyperactive Hypnos kid?
Yes! That’s something I fully support, because each reaction has an equal and opposite reaction, meaning for each possible power there is an opposite power, within reason. I think it depends on how the god manifested themselves upon meeting the mortal parent. The Twelve Olympians are gods/goddesses of multiple things, such as Hermes being the god of travelers and thieves. In a very simplified example, if you met Hermes at like a hostel vs if you met him on a heist of some sorts.
I think that in part explains the variance in powers, and how most children would have very similar powers, like a lot of Apollo kids are healers due to their parents meeting Apollo in a situation where he was a doctor or a healer of some sort.
However, that’s just a hypothesis. I’m sure there’s also a variance of randomness in there, because god’s don’t have DNA so there’s no hereditary traits. But, that brings up the question of how demigods get any traits from the parents like all Hermes kids having the same mischievous look annnnd now I’m getting off topic and geeking out over genetics.
But yeah, I totally support polar-opposite demigod powers.
