oh nice, another "I get to invalidate every single piece of their established defenses because the plot requires me to do so" enemy, my favorite. Fuck, I know they wave it away with the will of the world shit, but even then this got stale by the time the clown showed up, is this just what this story is now? Walking powerlevels with zero personality or traits that would make for engaging and interesting antagonists, just "I am powerful, you are weaklings. Die" until the plot demands "oh no you 'figured me out' I die now" repeating ad nauseam? Sick plot bro
Otherwise, they would not have met or met but would not have had a any serious conflict.
So story need some kind of puppeteering mechanism to counter them against each other.
In Japanese fantasy, the will of the world.
In Xianxia, the will of heaven.
The word "fate" or "great fate" is also often used in any works very often.
You can also often see gods or divine entities who cast self-fulfilling prophecies or weave "threads of fate" or other nonsense.
Oh yeah, "system quests" from which characters cannot escape and can only complete have also become a popular puppeteering mechanism in many works in recent years.
Another slightly unusual but still common one is "guiding intuition", characters do something because they feel something, and yes, in fact it's a vague posting in the form of actions.
There are literally no reasons of any kind, it's just that the reason is taken right out of the ass and the character believes in it and acts without any reason other than "intuition" feelings.
Sometimes it's very annoying to deal with.
