In Pokémon Pearl, Night Slash is a Dark-type move that can be learned by certain Pokémon through leveling up or by using a TM. Specifically, you can teach Night Slash to Pokémon like Sneasel or Honchkrow via leveling up. Additionally, you can find TM87 for Night Slash in the game, which is located in the Victory Road area. Make sure to check the compatibility of the Pokémon you want to teach it to, as not all Pokémon can learn the move.

Gallade can learn night slash, but not by level up. To teach Gallade night slash the player most go to Pastoria city and go to the south part of the city then go into the house at the top right of the southern part of the city. There is a guy who can teach Gallade night slash for a heart scale and all other moves it learns before that. I hope that helped!
