What is it that zombies don't like?

First we would need to question whether zombies are sentient, because if they aren't, then they don't know to be scared of anything. However, I think Frankenstein's monster is kind of like a zombie, too, except he's more human in his thinking. So I think zombies would be scared of fire, or at least, can be killed by fire.

If you're talking about something like resident evil, I think guns could work? They seem fearless though.

Well if you're talking about the dead rising from their graves kind of zombie, then nothing. They're dead.

But if you're talking about a parasite or some kind of pathogen to make people zombie like, like with rage, and an extreme desire for raw human flesh, then we wouldn't know for sure unless it happens.

Zombies don't like living things, if you throw a bunch of puppies at them, they will leave you alone. THAT Sounded awful.

I'm guessing an axe to the head

Bullets

I don't think they enjoy bullets

In video games like Warcraft and Final Fantasy, they are weak to Light, Healing or Holy spells. In movies they don't seem to able to swim.

It can vary from one work of fiction to another. Vampires are also prone to Sunlight, and if caught in it, they will fry. A wooden stake through their black hearts will also kill them for good.

Most undead creatures (which zombies happen to be) are usually prone to fire, and sometimes also daylight. They are immune to cold however. Acid eats away at everyhting, even rotting flesh. Magic might do the trick also, if Your zombies take Place in a medieval-like fantasy world With Magic. Then there's always the good old Method of sword or bullet through their black hearts...

I doubt they enjoy being shot in the head
