Santa Claus has a huge territory.
Not only the Earth, but the dude covers fictional realities as well. In the DC comics universe, for instance, Santa Claus faces some significantly more strenuous challenges than he might find here in our world.
For instance, suppose Santa Claus wanted to make a point and bring coal to a very naughty someone. Say a someone who is the embodiment of evil in the DCU. Someone like, say, Darkseid.
Fortunately for us, we don’t have to suppose. We can read about it, thanks to cartoonist extraordinary Ty Templeton.
Enjoy the day.
