The Worlds and Times of Doctor Who

And who in this world gains these powers? Perhaps one of the incarnations of the Time Lord known as the Doctor?

Or perhaps one of the companions from his longest known Regeneration cycle?

Maybe someone from the Doctor's present-day/current cycle?

Or perhaps someone from a companion-led spin-off show?

There are plenty of options and combos to explore. But who will gain these powers and become an Incest God/Goddess?
