Controlling the nature of a caught Pokémon?

Question

Does the Synchronize ability control a caught Pokémon's nature and if so, how does it work?

Answer 1

Effect

If the opponent causes a burn, paralysis, or poisoning of a Pokémon with Synchronize, the opponent receives the status condition too. Self-inflicted status conditions (for example through the use of an item) are not passed on.

Changes

In Generations 3-4, bad poison is only passed on as regular poison.

Outside of battle

If a Pokémon with Synchronize is the leading party Pokémon, there is a 50% chance of each wild Pokémon encountered having the same nature.

This doesn't really answer the question.

The question asks how synchronize works, and the answer told how synchronize works. What else do you want the answer to have?

I feel it's right. Go ahead and edit it if you think you're so smart!

Oh, I think I misunderstood the question. I was interpreting the question as "Does Synchronize have the ability to change the nature of Pokemon that have already been caught?".
