I have noticed in this discussion People seem to be making one general assumption. There are slight differences between the Roman and Greek aspects of the gods. So since Nico is the Son of Hades while Hazel is the daughter of Pluto then their Demi-god powers would slightly differ.

I could also apply to Thalia (daughter of Zues) and Jason (son of Jupiter).

It would've been interesting to see how Nico & Bianca powers were similar and different?
