he says that, while looking human himself. i wonder weather he is even human himself, or some kind of alien

Celestial Dragons and Elders are supposed to be humans, but they think themselves as better than “mere” humans. Perhaps there will be an alien twist incoming!

The fact the Seraphim carry on the feelings of their lineage factor “parent” with them seems a weird decision… are they just clones of the Original with better stats or will they develop their own feelings?

Judging by Vegapunk’s reaction, he didn’t intend them to carry the original’s feelings, but I guess the propensity to feel certain ways is inherited in the cloning process.
