Ahhh, I get it now. The first 3 gen2 mons are staters in the same way Bulbasaur, Charmander and Squirtle were! They even have the same grass, fire, water typing. (Yes I'm a bit slow).
So that means that the will be good specialists, close to the best in their type, and somewhat hard to collect (I evolved only 2 Charizards).
Do you have any idea how they will measure up to Gen 1 starters? They look cuter and less bad ass...
