Believable Antagonist +motivation?

[aimless]

A future antagonist in a story(not on site and this is 200-300 chapters in?) has an ability where they can talk to their alternate universe selves.

One of them lives in a reality where the book I’m writing exists in it, and they’ve read it in its entirety. Due to this, the antagonist now has access to future knowledge and is well aware that they’d be going against MC and that they’d die.

When they first meet, they’re around Large Mountain-Level whilst MC is City-Level. They take some actions that screw up the original plot, and now the MC wants to kill them as much as they want to kill him. Is this a believable motivation(for both parties), and how OP would you say this ability is?

As in what the antagonist knows

As in what the antagonist knows

The antagonist will die, so he hates MC, who will kill him. But he can see the future, so he does something and earns the hate of the MC. Is their hate for each other believable?

How can I answer this if I don't know what the antagonist does?

how OP would you say this ability is?

Depends. If he does something that makes the story deviate from its original course, does the story in the other world change?

I’m more curious as to why the antagonist didn’t kill or failed to kill the protagonist. I would think a large mountain could easily destroy a city. Especially when the antagonist should know the protagonists abilities and plans…

As for how OP, I believe it depends on both what George above mentioned and what other worlds the antagonist had access to.

For instance, say one of the worlds antagonist is some god realm cultivator capable of wiping out galaxy’s or some swordsman capable of splitting space or some other nonsense; then that’s OP. Even a more technologically advanced world could be great help. A alternate antagonist who’s super smart in one or more areas/ways would be OP as well.

There’s truly an unlimited amount of possibilities for with such an ability if not properly regulated by the author.

That sounds complicated. Write it carefully.

Damn this is quite a hard topic if your going to write something with time parallel wobbly crap but if you manage to pull it off. It might be a 5/5 antagonist or a messy 1/5 antagonist.

There isn’t like a god-level cultivator or something, but there is one from a more technologically advanced world, as well as a few others

Lately I have problems finding protagonist motivations believable, much less antagonist's.

The whole pataverse angle is a dangerous slope and its where this breaks down.

How would you react to know you are just a fiction?

Why isnt the antagonist having a complete mental breakdown? Why does anything matter when he has no freewill?

For example, I, being an eldritch horror, created you. You only believe you exist because I made you that way. You are just a game and I don't even believe you are real enough to care about.

If you found proof this was true, why aren't you in a padded room?
