Oof. And Parademons have killed nearly every species out there, including Tameranians. The Tameranian ability to metabolize sunlight without the biological limitation of their species would make them as strong as Superman. I say 'as strong' because supes has no real upper limit aside from what he decides himself (or the writers do,of course).
He can have the power of them all and make himself look human.Because he doesn't need to know human anatomy to do that there are a lot of species that look human tamerons ,kryptonian,and there are many new gods who look human.No human would make them self look inhuman if they can do anything about it
keep him close to the parademon look, ofc there would be differences but it'll show him as a better version as he kills darkseid, this would also make it so that he has some character development, conflict here in there as for what his past represents, maybe something to look forward to, probably even a way to mend his sins, especially if he wants the best of the best of every species, it's only natural for him to look inhuman.
