Things You'll Need
Instructions
Obtaining a Light Orb
Go to the Safari Zone in "Pokemon Emerald."
Engage in combat with Pikachus in the area.
Defeat Pikachus until one gives you a Light Orb. This happens 5% of the time, so it should take 20 or less fights to get the Light Orb.
Breeding a Pichu with Volt Tackle and Evolving It into a Pikachu
Go to the Day Care Center on Route 117 near Mauville.
Give your female Pikachu or Raichu the Light Orb.
Place the female Pikachu or Raichu with the Light Orb and a male Pikachu or Raichu in the Day Care Center to breed.
Return to the Day Care Center and pick up the egg after they have completed breeding.
Hatch the egg by walking around with it in your group. The hatched Pichu will have the Volt Tackle ability.
Evolve the Pichu by battling wild Pokemon in the area. When the Pichu evolves into a Pikachu, the Pikachu will have the Volt Tackle ability.
Transfer the Pikachu with Volt Tackle to "LeafGreen" by unlocking the National Pokedex in both "Emerald" and "LeafGreen" and then trading it through the PalPark.
