you can either use theft an reds pikachu or try catching a pikachu that has it. reds pikachu is a sure thing though.
yes you can catch pikachu on Pokemon heart gold but only in kanto! they are rare though
You get it from catching or thieving it from Pikachu. (Has a 5% chance of holding it.)
I know in Soul Silver your can only get him in the Viridian Forest . Pretty sure it is the same for Heart Gold
On Heart Gold Pikachu is found in Viridian Forest and on a few other poke walker zones
Any Pokemon 70+. RED'S Pokemon are Pikachu Blastoise Snorlax Lapras Charizard Venusaur
Pikachu to Raichi Eevee to Jolteon Shibibiru to Shibirudon (B&W)
breed pikachu.... nice bloody answer that helps alot!! u tool get pikachu from ilex forest or trade with st. lurge after beating him twice
Give Pikachu a Thunder stone and it will evolve into a Riachu. But in Pokemon Yellow, the Pikachu will not evolve. You can get thunder stones easy by mining them in Pokemon diamond and pearl but in soul silver and heart gold you need to buy them with athleet points at the athleet shop
