Bulbasaur - you go to Cerulean city (the blue place) and you make Pikachu happy.
There is a girl in Cerulean City that will give you a Bulbasaur if your Pikachu's friendship level is very high.
To get your friendship high, you usually just have to keep pikachu with you, having him participate in battles and leveling up. It just takes time. However, if you let him faint, his friendship will go down, so try not to let that happen.

The best and easiest way to get Bulbasaur is to first heal your Pikachu, then go into the house Bulbasaur is in. Use a potion on Pikachu until it says: It won't have any effect. Use the potion at least 5 times to be sure. Now look at Pikachu. He should be super happy. If he is, then talk to the girl and she will give you Bulbasaur.

Bulbasaur can be chosen as a started Pokemon in Red, Blue, FireRed and LeafGreen and one can be given to you by Professor Oak after compleating HeartGold or SoulSilver and by a woman in Cerulean City in Yellow version. You can also transfer a Bulbasaur from another game. There is no way to find wild Bulbasaur without a cheat device (except possibly by exploiting glitches in Red, Blue and Yellow) The only way to get an Ivysaur or a Venusaur is to evolve Bulbasaur (or transfer from somebody who has evolved a Bulbasaur).
