Why didn't Synchronize activate?

I was fighting a Tentacool and it used Poison Sting. I got poisoned, but the poison wasn’t passed on. Is this because Tentacool cannot be poisoned?

Pleaselog inorregisterto add a comment.

Even if Synchronize would have no effect due to the other Pokémon already having a status condition or the other Pokémon’s type, Ability, or team condition (e.g. Safeguard), it will still activate (revealing it as the Pokémon’s Ability), but have no effect.

Synchronize (Bulbapedia)

It probably did activate, but the poison wasn’t passed because Tentacool cannot be poisoned.

Hope I helped!

Yes, you are correct. Poison-types cannot be poisoned (except in the case of Corrosion)

Yes, Poison types like Tentacruel cannot be poisoned. Therefore, Synchronize didn’t activate. Synchronize will also not burn Fire types, will not freeze ice types, and will not paralyze Electric types Gen 6 onwards. It will not work if you fall asleep against a Pokemon with Insomnia either.

Tentacool is a poison type,and poison types are immune to poison.https://bulbapedia.bulbagarden.net/wiki/Poison_(status_condition)andhttps://bulbapedia.bulbagarden.net/wiki/Poison_(type)Corrosion allows poison types to be poisoned though.https://bulbapedia.bulbagarden.net/wiki/Corrosion_(Ability)
