I've been reading the enderverse stories in the recommended order on audible (which is close to chronological rather than publish order) and just finished up Xenocide and Children of the Mind and something occurred to me.
Ender spends thousand of years travelling the galaxy with his sister as a companion. Along the way, he discovers Jane. He plays key roles in many events in history, saving Earth and all of humanity, solving problems, helping people.
Eventually he settles on Lusitania and once again plays a key role in saving the day, bringing 4 distinct species together (humanity, formics, piggies and Jane) and figures out how to use the philotic nature of the universe with the help of Jane and others to develop faster than light travel.
Since Jane needs 'simple' objects to transport instantaneously from one place to another, they build a new design for their 'ships' that is a smaller, simple, boxy habitat.
Ender inadvertently creates other versions of himself and eventually gives one to Jane and grows weary of his own existence and moves his essence from all three bodies into the form his mind created of his memories of young Peter. Ender essentially 'dies' or passes on from living life as Andrew to become a new person as Peter v2. As Peter, he meets another woman and takes her as his companion, and they finish off Ender's role of saving the 4 species and the story ends with them both interested in travelling the galaxy again, in their small, boxy, instantaneous travel 'ship', pursuing their own ambitions and helping others by solving problems they confront along the way.
Then it hit me....
Ender/Peter v2 is the first incarnation of Dr. Who!!!!
