Favorite Kanto Starter: Blastoise
Favorite Johto Starter: Typhlosion (During the 2nd gen, I always give it Thunderpunch and Earthquake to handle its weaknesses)
Favorite Hoenn Starter: Swampert (The reason Mudkip is my favorite, its because, when it evolves, it adds a 2nd type that's makes it immune to Electric-type. That's why it made it useful in the Electric-type Gym. Just need to watch out for Grass-type Pokemon)
