STAR WARS is really just a treatise on microbial evolution and the concept of the selfish gene. See below for more details.
So here’s the idea. The concept of midichlorians was introduced in the prequels. They are “a microscopic lifeform that reside within all living cells and communicate with the Force”. So essentially mitochondria, but powered by the Force. Han Solo has a great quote in episode IV,
Kid, I’ve flown from one side of this galaxy to the other, and I’ve seen a lot of strange stuff, but I’ve never seen *anything* to make me believe that there’s one all-powerful Force controlling everything. ‘Cause no mystical energy field controls *my* destiny. – Han Solo
But with midichlorians you now have a genetically discrete entity that is the sole communication with the powerful Force. The midichlorians want, in an evolutionary sense, to preserve and continue their lineage- they are ‘selfish’. So it stands to reason that they would have a say in what was going on with their hosts. A ‘host’ is simply a very large (relatively speaking) machine to enact the plans of the midichlorians. Of course. A kind of large biosuit for battle. So it’s amusing to think of them controlling all the battles like they’re playing video games.
Incidentally, this is not my first Star Wars inspired comic. That would be here.
