If you're ever in a christmas-y mood, I'd recommend the Klaus comics by Grant Morrison, which are published through Boom studios.
It starts with a mini that tells the origin of Santa Klaus, reimagining him as a sort of Robin Hood esque folk hero. Then after the mini there's a yearly one shot showing Santa's various adventures.
The primary argument I've heard is based on scaling. Basically, base Galaxia supposedly scales higher than all of the villains previous to her, and that includes someone with "Manipulate an entire nebula" levels of TK
Not sure if there is gonna be a long run, this is feeling very "Final arc"-y to me.
I'm late but happy birthday
