I'm not gonna lie I really wanted to say kryptonain but in shows like young justice and superman and Lois they make it clear that a kryptonain hybrid won't be as strong as a full kryptonain which is why I'm saying viltrumite because you get a decent majority of powers a kryptonain would have minus the super senses plus Nolan told Mark that the viltrumite basically overrides the human DNA and your basically a full viltrumite and with maturity you'll gain full viltrumite powers.
