So I'm gonna kill Santa Claus
When I hear those reindeer pause
I'm gonna break the law
This Christmas, don't got a wishlist, I got a hit list
And at the top of it is old Saint Nicholas
Nothing against him, it's just business
I ain't the Grinch, but I'm gonna steal Christmas!
Holidays like Christmas usually have a beloved and well known central figure associated with them. Santa Claus is perhaps the most well known, and he and the others are usually said to have magical powers that let them spread their holiday cheer around the world. The kids love them too, which is a bonus.
Therefore, in works based around these holidays, you'll often find villains who envy these holiday mascots and want their power for themselves.
This trope isn't about characters simply pretending to be Santa or any other holiday figure, this is about them performing a coup and gaining their power.

Unhappy about the competition, Schäfer arranged for an older member of his cult to dress up as Santa and get on a boat on a river near his cult's compound, while he gathered the children of the cult, loaded them onto a bus, and drove them out to the nearby river, where, he told them, Santa was coming to visit. When the sailing Santa appeared, Schäfer then drew a pistol loaded with blanks from his belt and "shot" Santa, who collapsed into the river and sunk below the surface. Then Schäfer turned to the children assembled before him and proclaimed that Santa was dead and from that day forward, Schäfer's birthday was the only holiday the cult was allowed to celebrate.
