A thought crossed my mind while posting in the caption contest. So, Spock dies, his torpedo soft-lands on Genesis, and the planet magically resurrects him a new body for his katra to get transferred into. So, we know that the Genesis planet can rejuvenate or perhaps create a new body using a person's DNA.
So, why didn't Khan get a new body too? His DNA was part of the planet too (along with the entire U.S.S. Reliant), so what was so different that he couldn't come back too?
