In Pokémon XD: Gale of Darkness, you can get Pikachu to learn Volt Tackle by first obtaining a Pichu that knows the move. To do this, you need to breed a Pikachu or Raichu with a Pokémon that knows Volt Tackle, such as a female Pikachu or Raichu with a male Electrike or Manectric. Once you have the Pichu, level it up until it evolves into Pikachu, and it will retain Volt Tackle.
